2012, DOI: 10.1007/s10103-012-1093-4

Abstract

It is now known that erbium lasers are effective in composite removal, but there is minimal information about their efficacy on recycling of ceramic brackets. This study, therefore, aimed to determine the percentage of remaining adhesive on the base and the shear bond strength of debonded ceramic brackets after being reconditioned by an Er,Cr:YSGG (erbium, chromium: yttrium–scandium–gallium–garnet) laser. Thirty premolars were divided into three groups, then bonded with mechanical retention ceramic brackets according to the bracket base conditions: (1) new brackets; (2) debonded brackets cleaned of adhesive with the Er,Cr:YSGG laser at 3.5 W; and (3) debonded brackets cleaned of adhesive with the Er,Cr:YSGG laser at 4 W. Before bonding, the percentage of remaining adhesive on the bases of reconditioned brackets was calculated by using stereomicroscopic images through an image processing software. The brackets were then tested in shear mode in a universal testing machine and the adhesive remnant index scores were determined. The percentage of remaining adhesive on the bases of brackets that were cleaned by the Er,Cr:YSGG laser at 4 W (3.1 %) was significantly lower than that of the 3.5-W laser group (5.9 %) (p = 0.03). No significant difference was found in bond strengths between the new and the reconditioned brackets (p = 0.19). The frequency of bond failure at the enamel-adhesive interface was lower in the laser-reconditioned brackets when compared to the new brackets. The application of Er,Cr:YSGG laser was efficient in removing adhesive from bases of debonded ceramic brackets because it produced comparable bond strengths to new brackets while reducing the risk of enamel damage during debonding.

DOI: 10.1111/j.1600-0501.2012.02490.x

Abstract

Objective

The aim of the present study was to evaluate morphological changes induced by glycine powder air polishing on titanium surfaces and its effect on bacteria recolonization in comparison with sodium bicarbonate powder.

Materials and methods

5 mm wide and 1 mm thick titanium grade II disks were divided into three groups of treatments: (i) no treatment; (ii) air polishing with glycine powder; (iii) air polishing with sodium bicarbonate powder. Specimens were characterized by laser profilometry, scanning electron microscopy (SEM) and then installed onto removable appliances worn for 24 h by healthy volunteers. Surface contamination was evaluated using SEM and counting the number of colony forming units (CFU).

Results

SEM observation revealed an increased roughness with the formation of craters on samples treated with sodium bicarbonate powder, while not in glycine ones. Statistical analysis failed to show significant differences of both R_a and R_max parameters in treated groups. SEM observation of specimens surfaces, after 24 h of permanence in the oral cavity, showed a higher contamination of the disks treated with sodium bicarbonate compared with those not treated (P < 0.05). Conversely, the group treated with glycine showed the lower contamination if compared with bicarbonate-treated group (P < 0.05).

Conclusions

Air polishing with glycine powder may be considered as a better method to remove plaque from dental implant because glycine is less aggressive than sodium bicarbonate powder. Moreover, the use of glycine powder seems to have an active role on the inhibition of bacterial recolonization of implants in a short test period (24 h). Further studies are needed to demonstrate the bacteriostatic properties of glycine, envisaged on the basis of reduced contamination of the disks polished with glycine compared with those not treated.

10 Practical Tips for Pulling a Child’s Loose Tooth

2012-05-31T09:30:00.000-04:00

It sure is a good thing that kids come with multiple sets of teeth, because they sure seem to go through them quickly. If you’ve got a little one with a tooth that’s worked itself loose, you may be thinking of completing the job yourself. For you, we offer this list of 10 practical tips for pulling a child’s loose tooth:

Don’t DIY – We thought we should get this one out of the way up front. Some things are best left to the professionals, and proper hygiene is important here, which is something that is more difficult to maintain in the average home environment. But, if you insist, read on …
Wash – In the interest of the aforementioned hygiene, wash your hands thoroughly in warm water with a mild soap. That way your hands are germ free as they enter your child’s mouth.
Calm the Patient – Keep your child preoccupied by telling a story, providing a video, a game or TV program they can amuse themselves with while positioned for the extraction. Try to get their attention on anything other than the tooth you’re about to rip from their mouth.
Gauze – Use a sterile gauze pad rather than your bare fingers for grasping the tooth for removal. Again, the less germs the better!
Blood – There’s going to be some, and it may involve the gums. Make sure you’ve got a means for quickly cleaning it up, and that your child is positioned so as not to swallow any accidentally.
Pressure – Apply it to the bleeding area until it subsides, using more of that gauze you’ve gotten at the ready. It should stop bleeding fairly quickly. However, if bleeding persists, get medical help.
An Apple a Day … – To facilitate removal, try having your child eat an apple first. This could pry the tooth loose by itself, effectively helping you avoid all the drama that comes with yanking out a loose tooth.
Work it, Baby – Work the tooth back and forth to loosen it further until you can easily pull it out. In fact, let them work the tooth back and forth… it will give them something to do all day.
Ice, Ice, Baby – Ice works wonders in these kinds of situations. An ice cube or pack could help deaden pain during this process if your child protests excessively.
Tooth Fairy Time – Have your child place her trophy tooth under her pillow, and patiently wait until morning. You’ve saved enough on a dental visit to make it worth her while, and it will make all the blood and tears worth it when you see her face light up with joy when she discovers the tooth fairy really did come in the middle of the night.

Pulling out your child’s tooth has all the makings to shape up into a horrific experience. But once it’s out they’ll quickly forget the aforementioned pain and be chomping at the bit for nighttime and a chance at meeting the tooth fairy.

The MPLC Launches Umbrella License® for Pediatric Dentists

2012-05-30T10:30:00.000-04:00

American Academy of Pediatric Dentistry among charter organizations to partner with MPLC

Los Angeles, CA – The Motion Picture Licensing Corporation (MPLC), an independent copyright licensing agency, is introducing its Umbrella License for Pediatric Dentists. The American Academy of Pediatric Dentistry (AAPD) is among the first to partner with MPLC for the purpose of offering this license to its members, allowing dentists to show movies and other children’s programming in a copyright compliant manner. Through their agreement, AAPD members can obtain the Umbrella License at a discounted rate.

The license provides dentists the performance rights to show movies, popular children’s programs, educational documentaries, and other audiovisual content for entertainment purposes in their patient waiting rooms and exam rooms. Movies can be shown from more than 425 Hollywood studios, independent, special interest, children-related, and foreign producers. Once a license is secured, pediatric dentist office administrators can rent or purchase movies and play them without any further reporting.

According to the US Copyright Act, Title 17 of the United States Code, copyrighted motion pictures and other programs that are available for rental or purchase in any legal format, are intended for personal, private, and home use only. Exhibitions outside of the home, such as within a medical office, require a public performance license. Regardless of whether or not an admission fee is charged, this legal requirement applies equally to for-profit and not-for-profit organizations.

“Children are sometimes apprehensive when going to see the dentist, and seeing a familiar face on the screen can sometimes help soothe a child’s emotions and alleviate stress,” said Sal Laudicina, President of the MPLC Licensing Division. “We designed our Umbrella License as a convenient and comprehensive copyright compliance solution to provide a wide array of program possibilities for pediatric dentists. AAPD members now have the peace of mind to show the type of movies and programming children know and love, in accordance with federal law. We are happy to have forged a relationship with the AAPD and look forward to making it possible for its members to provide their patients with fun entertainment to look forward to at their next visit.”

“The AAPD is pleased to partner with the MPLC so that our members can conveniently obtain a discounted copyright license and have the option of entertaining their patients with child-friendly video entertainment,” said Dr. John S. Rutkauskas, Chief Executive Officer of the AAPD.

Maxillary Overdentures Supported by Anteriorly or Posteriorly Placed Implants Opposed by a Natural Dentition in the Mandible: A 1-Year Prospective Case Series Study

2012-05-29T08:00:00.000-04:00

Slot, W., Raghoebar, G. M., Vissink, A. and Meijer, H. J. A. (2012), Maxillary Overdentures Supported by Anteriorly or Posteriorly Placed Implants Opposed by a Natural Dentition in the Mandible: A 1-Year Prospective Case Series Study. Clinical Implant Dentistry and Related Research. doi: 10.1111/j.1708-8208.2012.00459.x

ABSTRACT

Background: For maxillary overdenture therapy, treatment guidelines are missing. There is a need for longitudinal studies.

Purpose: The purpose of this 1-year prospective case series study was to assess the treatment outcome of maxillary overdentures supported by six dental implants opposed by natural antagonistic teeth in the mandible.

Materials and Methods: Fifty patients were treated with a maxillary overdenture supported by six dental implants, either placed in the anterior region (n = 25 patients) or in the posterior region (n = 25 patients). Items of evaluation were the following: survival of implants, condition of hard and soft peri-implant tissues, and patients' satisfaction.

Results: One-year implant survival rate was 98% in the anterior group and 99.3% in the posterior group. Mean radiographic bone loss in the anterior and posterior groups after 1 year of loading was 0.22 and 0.50 mm, respectively. Mean scores for plaque, calculus, gingiva, bleeding, and pocket probing depth were low, and patients' satisfaction was high, with no differences between the groups.

Conclusion: Six dental implants placed in either the anterior region or the posterior region of the edentulous maxilla, connected with a bar, and opposed by antagonistic teeth in the mandible supply a proper base for the support of an overdenture.

Water sorption characteristics of restorative dental composites immersed in acidic drinks

2012-05-26T08:30:00.000-04:00

Dental Materials
Volume 28, Issue 6 , Pages e63-e70, June 2012

Abstract

Objectives

To determine the diffusion coefficient, water sorption and solubility of various types of restorative dental composites and to evaluate the effect of acidic media (orange juice and coke) on their characteristics.

Methods

Resin composite specimens (Filtek™ Z350, Spectrum^® TPH^®3 and Durafill^® VS) were prepared in a stainless steel mold of 1mm thickness and 10mm diameter (n=5) and light-cured. All samples were dried at 37°C, immersed in media (distilled water, orange and coke) at 37°C and weighed at suitable time intervals (15, 35, 155, 320, 785, etc.min) until 40 days of immersion and then were dried again for 40 days. Diffusion coefficient (m²s⁻¹) was determined according to Fick's second law while water sorption and solubility (μg/mm³) were calculated based on BS EN ISO 4049:2000. Data of water sorption and solubility were analyzed with One-Way ANOVA and post hoc Scheffe test at p=0.05.

Results

The experimental data obtained were obeyed and nearly fitted to the diffusion theoretical data plot. The highest values of diffusion coefficients were presented by Durafill^® VS (32.23–45.25×10⁻¹³m²s⁻¹). Diffusion coefficients of Filtek™ Z350 and Spectrum^® TPH^®3 were the highest when immersed in coke media followed by distilled water and orange juice. The water sorption of most composites was significantly increased after immersion in coke and orange (p<0.05). Meanwhile only Spectrum^® TPH^®3 showed an increase in solubility when immersed in coke media. Z350 presented the highest water sorption after immersion in distilled water and coke (16.13 and 18.22μg/mm³) while Durafill^® VS presented the highest solubility (7.20–9.27μg/mm³).

Significance

The exposure of restorative dental composites to acidic drinks can cause an increase in diffusion coefficient, water sorption and solubility parameters which may accelerate the degradation process and thus reduce the life span of composite restoration.

Effects of common beverage colourants on colour stability of dental composite resins: The utility of a thermocycling stain challenge model in vitro

2012-05-25T10:00:00.000-04:00

Journal of Dentistry

Available online 27 April 2012

Abstract

Objectives

To study the colour stability of dental composite resins using a thermocycling stain challenge model accounting for the complex effects of oral environment and tooth brushing.

Methods

Composite resin discs were made from Filtek Supreme Ultra (FiltekSU), TPH3 and Renamel, and subjected to thermocycling challenges in warm coffee (55 °C/pH 5.2) and a cold tea and fruit juice mixtures (5 °C/pH 3.6) for a total of 1000 cycles with 30 seconds dwell time in each solution per cycle. Colour was assessed in the CIELAB colour space using a Crystaleye dental spectrophotometer before and after thermocycling, and after brushing vigorously for 3 min. The thermocycling stain challenge was repeated for a second 1000 cycles and the discs were brushed again. Colour changes were compared among the 3 groups using Kruskal–Wallis test.

Results

All 3 groups showed statistically significant colour changes after stain challenge, with ΔE* as 5.74 for FiltekSU, 3.21 for TPH3 and 2.52 for Renamel. Colour change was more significant in FiltekSU than in TPH3 and Renamel (p < 0.05). After brushing, colour recovered mostly to its original CIELAB values in TPH3 and Renamel but less so in FiltekSU. The second round of thermocycling stain challenge resulted in colour changes in FiltekSU that largely could not be removed by vigorous brushing.

Conclusions

Colour stability of FiltekSU is inferior to that of TPH3 and Renamel. The thermocycling stain challenge model can potentially differentiate surface staining that can be removed by brushing from true discolouration of the material that is refractory to oral hygiene procedures.

Who Profits from Dental Non-Profits? Not you!

2012-05-24T09:00:00.000-04:00

My friend Fred Joyal of 1-800 Dentist has written an excellent blog post on Delta Dental of Washington attitude toward dentists but in effect it applies to many insurances companies. Just because the insurance company is a non profit does not mean it is benevolent to the dentists. In the blog post there are recent comments from James Dwyer the CEO of the Washington Dental Plan which every dentist should read as to how the insurance companies view the dentists.

Recently Delta Dental of NJ has told us that we can expect a 4-5% reduction in payouts this year. No one really know what this means and the NJ Dental Association does not want to comment on this either. These Insurance Company CEO's and their corporate attorneys make much more then the dentists who submit claims. Yet they want us to work harder. Delta of NJ has money for the CEO and can give money to many benevolent charities but has to reduce reimbursement. Thus although they are non profit they act just like for profit entities.

Call your congressman and support the elimination of anti-trust measures that insurance companies have been granted by law.

Go read the Fred's blog post and see exactly where we stand.

Clinical performance of long-span zirconia frameworks for fixed dental prostheses: 5-year results

2012-05-23T10:30:00.000-04:00

SCHMITTER, M., MUSSOTTER, K., RAMMELSBERG, P., GABBERT, O. and OHLMANN, B. (2012), Clinical performance of long-span zirconia frameworks for fixed dental prostheses: 5-year results. Journal of Oral Rehabilitation. doi: 10.1111/j.1365-2842.2012.02311.x

Summary The purpose of this prospective cohort study was to assess the performance of tooth-supported, long-span, zirconia fixed dental prostheses (FDPs). Thirty FDPs with span lengths from 36 to 46 mm (mean 40·33 mm), with 4–7 units and with connector dimensions ∼9 mm² were inserted (19 in the posterior region, 11 including anterior teeth) using glass–ionomer cement. The performance of the FDPs was assessed (aesthetic evaluation, failures, hypersensitivity/tooth vitality, secondary caries, pocket depth, decementation, and chipping) at baseline and after 5 years. Cox regression analysis was performed to identify risk factors. There were 16 failures after 5 years. Framework fracture occurred for two FDPs, four FDPs had to be re-cemented, one abutment tooth had to be treated endodontically, one abutment tooth fractured and cohesive failure of the veneer occurred for eight. Four FDPs had to be replaced, so survival was 82%. The aesthetics were rated as excellent by the patients at baseline and good at the 5-year recall. Cox regression analysis showed that both length [P = 0·05, exp(B) = 1·22] and location [P = 0·019, exp(B) = 4·09] of the FDP were risk factors for failure. Compared with the previously published 2-year results, the incidence of complications increased dramatically. Additionally, it was shown that long-span FDPs in the molar region are at greater risk of failure than FDPs in the anterior region.

Shofu launched a new Giomer Pit and Fissure Sealant (BeautiSealant)

2012-05-22T10:00:00.000-04:00

BeautiSealant is a tooth colored, fluoride recharging, pit and fissure sealant with a self-etching primer that speeds treatment time by eliminating the need for phosphoric acid etching. Using an advanced, self-etching primer, BeautiSealant helps preserve healthy enamel that is easily demineralized with harsh acid-etchants, while still maintaining superior bond strength. Seeping deeply into pits and fissures, our HEMA-free primer bonds equally to enamel or dentin preparing the tooth surface for a secure and long-lasting bond. Providing flawless handling characteristics, both the viscosity and the syringe design contribute to a smooth, bubble free consistency, and reduce the common issue of overfilling. Unlike many competitors, BeautiSealant is also highly radiopaque offering clear visibility at follow-up. As the newest member of the GIOMER family, BeautiSealant is filled with Shofu’s proprietary Surface Pre-Reacted Glass (S-PRG) with proven cariostatic properties, acid neutralization, and plaque inhibition.

10 Tips for Preparing Your Child for the Dentist

2012-05-21T09:03:00.000-04:00

From Nanny.net

Dentist visits are a real source of angst for children, but a necessity for dental health. So it’s in everyone’s best interest for your child to be up to making those appointments without too much fuss. Not to mention the fact that better preparation helps children get the most from their dental care. The following are ten tips for preparing your child for the dentist:

Brush Your Teeth. – It makes it much easier to spot any potential problem areas when your child’s teeth are clean. Have them brush thoroughly just prior to their visit.
Floss – Similarly, apart from good overall practice, flossing will keep the spaces between their teeth clear, making it easier to spot cavities, as well as prevent them.
Rinse – In addition to killing harmful germs in their mouths, the dentist will be very grateful to your child for this courtesy. It may burn a little, but there are non-alcohol rinse alternatives.
Reward – It helps to associate a not-so-great experience with a more positive end result. Fewer cavities may not excite your child, but a visit to the movies, a park, or arcade afterward might do the trick.
Stress Reduction – Coordinate your child’s office visit with an activity that will help her relax and get her mind off the anxiety of a dental visit. If you can change your child’s thinking about the dentist, it will make the experience better overall.
Explain What to Expect – If this is your child’s first visit, talk to them about what they will be doing, and why. The dentist will be looking in your mouth to make sure your teeth are okay, etc. The more they know, the less stress they will have.
Read a Book – Choose a book about a child’s first dentist visit to help them understand and mentally prepare for it. Make it a normal part of life and not something to dread.
Start Early – The earlier the better for the child’s first visit. You can start generally between 6 and 12 months. You especially want to make the first visit a non-emergency one. This will help acclimate your child to what to expect, and to develop trust in her dentist.
Play Dentist – You can take turns with your child, alternately playing the roles of dentist and patient. Let him get accustomed to checking teeth, and having his checked, in a fun and reassuring setting before heading out for the real thing.
Schedule Early in the Day – Avoid the potential for a cranky or hungry toddler by getting an early appointment whenever possible. It will help make your visit a more pleasant one for everyone.

No matter what age your kids are, going to the dentist is an important part of life. Good dental hygiene is vital to good health. Start early and make visiting the dentist fun.

Heraeus and Benco Dental Team Up to Help Customers Turn Scrap into Cash

2012-05-19T10:00:00.000-04:00

Trusted manufacturer and dealer partner to increase customer liquidity

SOUTH BEND, Ind., May 14, 2012 /PRNewswire via COMTEX/ -- Heraeus Kulzer, LLC, the worldwide leader in dental esthetics, announced today that it is partnering with Benco Dental to make it more profitable and convenient for Benco customers to trade in their scrap metals for cash.

Heraeus, the world's largest private precious metal refiner, and Benco, the largest privately owned, full-service dental distributor in the United States, note that there are three reasons why dental practices and laboratories should cash in their scrap on a regular basis:

Accountability: Scrap is unaccountable, while regular, frequent shipments allow customers to keep track of their assets.

Liquidity: Precious scrap is not liquid until it is cashed in; raw scrap collects no interest.

Security: Scrap stashes are not insured; insurance companies will not reimburse in the event of fire or theft.

Countless laboratories and dental offices trust Heraeus Precious Metal Refining to provide exceptional service and unsurpassed integrity. The company guarantees fair market value for customers' precious metals (gold, platinum, palladium and silver). Settlement is based on the London PM prices on the day of assay valuation. Customers can be paid in gold investment coins, with a check, and/or electronic transfer.

Heraeus Precious Metal Refining heats, melts, separates and analyzes precious metals in a single location to give laboratories and dentists the highest possible return for their dental scrap metal. By eliminating surprise fees and minimum lot charges, Heraeus is able to give its customers the utmost in value and service.

Considered the global gold standard in dental esthetics materials, Heraeus operates a state-of-the-art refinery in Newark, New Jersey. The facility receives more than 25,000 scrap shipments annually, 80% of which are from existing loyal customers. Because it processes its own scrap from beginning to end, Heraeus offers direct, personalized contact without any middlemen, saving time and money for its valued customers.

Effect of an annual benefit limit on adult dental expenditure and utilization: a cross-sectional analysis

2012-05-18T11:00:00.000-04:00

Morrison, G. C., Hendrix, K. S., Arling, G., Hancock, E., Hus, A. M., Rosenman, M. B. and Swigonski, N. L. (2012), Effect of an annual benefit limit on adult dental expenditure and utilization: a cross-sectional analysis. Journal of Public Health Dentistry. doi: 10.1111/j.1752-7325.2012.00341.x

Abstract

Objectives: Despite widespread use of dental benefit limits in terms of the types of services provided, an annual maximum on claims, or both, there is a dearth of literature examining their impact on either cost to the insurer or health outcomes. This study uses a natural experiment to examine dental care utilization and expenditure changes following Indiana Medicaid's introduction of a $600 individual annual limit on adult dental expenditure in 2003.

Methods: In a before and after comparison, we use two separate cross-sections of paid claims for 96+ percent of the Medicaid adult population. Paid claims were available as a per-member-per-year (PMPY) figure.

Results: Between 2002 and 2007, the eligible population decreased 3 percent (from 323,209 to 313,623), yet the number of people receiving any dental services increased 60 percent and total Medicaid dental claims increased 18 percent (from $34.1 million to $40.1 million). In both years, those Dually (Medicare/Medicaid) Eligible had the largest percentage of members receiving services, about 75 percent, and the Disabled Adult group had the lowest percentage (5-8 percent), yet both populations are likely to have high dental need due to effects of chronic conditions and medications.

Conclusions: The increase in the number and percentage of people receiving Diagnostic and Restorative care suggests that the expenditure limit's introduction did not impose a barrier to accessing basic dental services. However, among those receiving any service, PMPY claims fell by 37 percent and 31 percent among the Dually Eligible and Disabled Adults categories, respectively, suggesting that the benefit limit affected these generally high need populations most.

Development of polarization dental imaging modality and evaluation of its clinical feasibility

2012-05-12T11:30:00.000-04:00

Journal of Dentistry

Available online 24 April 2012

Abstract

Objectives

In the evaluation of tooth color, the specular reflection caused by roughness or saliva on the tooth surface may cause artifacts in image analysis. In this study, a polarization dental imaging modality (PDIM) was developed to obtain cross-polarized images and, therefore, to address the problem of specular reflection. Its clinical validity was evaluated by performing 3 studies of shade tab selection for implant, plaque distribution detection, and evaluation of tooth whitening.

Methods

In vivo human tooth and shade guide color images were obtained, and the minimum color difference between them was calculated for the best color matching shade tab selection. A dental plaque disclosing agent was used to differentiate plaque regions on teeth, and plaque distribution was detected by applying the K-means algorithm. In vivo human teeth were treated with a commercial tooth whitening gel, and tooth whitening was quantitatively evaluated using the PDIM images.

Results

The PDIM produced repeatable glare-free tooth color images by effectively removing the specular reflection from the tooth surface. The cross-polarized tooth images were successfully utilized for shade guide selection, plaque detection, and tooth whitening by minimizing artifacts in the quantitative image analysis. The PDIM could simultaneously provide both qualitative and quantitative assessment of the tooth condition in clinical diagnosis.

Conclusions

The clinical feasibility of the PDIM was successfully verified in 3 clinical studies by showing its clinical efficacy as a new imaging modality.

Reno researchers discover new research use for plaque

Interdisciplinary work yields new, easier, less destructive way to examine diets of ancient peoples by using dental calculus

RENO, Nev. – While we may brush and floss tirelessly and our dentists may regularly scrape and pick at our teeth to minimize the formation of plaque known as tartar or dental calculus, anthropologists may be rejoicing at the fact that past civilizations were not so careful with their dental hygiene.
University of Nevada, Reno researchers G. Richard Scott and Simon R. Poulson discovered that very small particles of plaque removed from the teeth of ancient populations may provide good clues about their diets. Scott is chair and associate professor of anthropology in the College of Liberal Arts. Poulson is research professor of geological sciences in the Mackay School of Earth Sciences and Engineering.
Scott obtained samples of dental calculus from 58 skeletons buried in the Cathedral of Santa Maria in northern Spain dating from the 11th to 19th centuries to conduct research on the diet of this ancient population. After his first methodology met with mixed results, he decided to send five samples of dental calculus to Poulson at the University's Stable Isotope Lab, in the off chance they might contain enough carbon and nitrogen to allow them to estimate stable isotope ratios.
"It's chemistry and is pretty complex," Scott explained. "But basically, since only protein has nitrogen, the more nitrogen that is present, the more animal products were consumed as part of the diet. Carbon provides information on the types of plants consumed."
Scott said that once at the lab, the material was crushed, and then an instrument called a mass spectrometer was used to obtain stable carbon and nitrogen isotope ratios.
"It was a long shot," he said. "No one really thought there would be enough carbon and nitrogen in these tiny, 5- to 10- milligram samples to be measurable, but Dr. Poulson's work revealed there was. The lab results yielded stable carbon and nitrogen isotope ratios very similar to studies that used bone collagen, which is the typical material used for this type of analysis."
Scott explained that the common practice of using bone to conduct such research is cumbersome and expensive, requiring several acid baths to extract the collagen for analysis. The process also destroys bone, so in many instances, it isn't permitted by museum curators.
As for using hair, muscle and nails for such research, Scott said, "They are great, when you can find them. The problem is, they just don't hold up very well. They decompose too quickly. Dental calculus, for better or for worse, stays around a very long time."
Scott said that although additional work is necessary to firmly establish this new method of using dental calculus for paleodietary research, the results of this initial study indicate it holds great potential.
"This is groundbreaking work," Scott said. "It could save a lot of time and effort, and also allow for analysis when things like hair, muscle and nails are no longer available."

Peri-implantitis susceptibility as it relates to periodontal therapy and supportive care

2012-05-07T11:30:00.000-04:00

During Arthritis Awareness Month, the New Jersey Society of Periodontists Explains the Periodontal Disease Connection

During Arthritis Awareness Month, the New Jersey Society of Periodontists Explains the Periodontal Disease Connection

Research Indicates that Patients with Rheumatoid Arthritis are Nearly Eight Times More Likely to Have Periodontal Disease

Morganville, NJ (May 3, 2012) – May is Arthritis Awareness Month, and the New Jersey Society of Periodontists (NJSP) would like patients and caregivers alike to be aware of the link between periodontal disease, a chronic inflammatory disease of the gums, and rheumatoid arthritis, a chronic inflammatory disease of the joints.

“The common denominator here is the inflammatory aspect of both diseases,” explains Dr. Scott Zirkin, president of the NJSP. “Periodontal disease is a chronic bacterial infection that stimulates an inflammatory response, which in turn imposes a burden on a person’s immune system. Over time, sustained inflammation can lead to the destruction of connective tissue and bone tissue. This destruction affects both teeth and joints.”

According to Linda Gruskiewicz, executive director of the New Jersey Chapter of the Arthritis Foundation, “We are very much aware of the existing studies linking periodontal disease to arthritis and believe that arthritis patients can benefit from the collaborative care of a periodontist and a physician.”

Gruskiewicz is referring to a study published a few years ago in the Journal of Periodontology, which found that patients who had both periodontal disease and severe rheumatoid arthritis experienced reduced arthritis pain, a reduced number of swollen joints, and a reduced degree of morning stiffness when their periodontal disease was finally treated and brought under control. “The mouth/body connection is very strong and should not be underestimated by those living with arthritis or their caregivers,” says Zirkin.

“Some arthritis patients may eventually develop periodontal disease because the restricted strength and mobility of their hands prevents them from following proper oral hygiene tasks, such as brushing and flossing,” adds Gruskiewicz. “It’s a constant challenge for patients and caregivers alike.”

To arthritis patients who have difficulty taking care of their oral health, Dr. Zirkin offers the following advice: “The use of power toothbrushes, oral irrigators, dental floss holders, and prescription-only mouth rinses have proven to be extremely helpful for arthritis sufferers with limited manual dexterity. What’s more, regular visits to a periodontist who can provide advanced periodontal treatment can help keep periodontal disease under control, and perhaps minimize some of the symptoms of arthritis as well.”

About the New Jersey Society of Periodontists:

The New Jersey Society of Periodontists (NJSP) is an organization of New Jersey dentists who specialize in the art, science, and practice of periodontics, including implants. The group is dedicated to advancing the knowledge base and understanding of periodontal diseases, as well as advancing ideas in treatment techniques in implantology. The NJSP seeks to explore and discuss problems of mutual interest with those in the practice of periodontics and implant dentistry. It supports the public, periodontists, and all dental professionals involved in the oral care of patients of all ages. For more information, please visit www.njperio.org.

About the New Jersey Chapter of the Arthritis Foundation:

The Arthritis Foundation is the only national not-for-profit organization that supports research and programs to help the 50 million people in the United States affected by the more than 100 types of arthritis and related conditions. The Arthritis Foundation is the largest private, not-for-profit contributor to arthritis research in the world, funding more than $380 million in research grants since 1948. The Foundation helps people take control of arthritis by providing public health education; pursuing public policy and legislation; and conducting evidence-based programs to improve the quality of life for those living with arthritis.

Carestream Dental Debuts New Scheduler for CS SoftDent, Announces CS 1600 Now Available

2012-05-04T09:41:00.003-04:00

New Solutions Emphasize Workflow and Efficiency to Improve Patient Care

ATLANTA – Carestream Dental today previewed the new Scheduler for CS SoftDent practice management software at the California Dental Association – South meeting (CDA – South), being held through Saturday, May 5, at the Anaheim Convention Center in Anaheim, Calif. The company also announced that the CS 1600 intraoral camera is now available for sale.

During CDA – South, the Carestream Dental team will showcase three solutions that are designed to streamline workflow and improve communication within practices and with patients. This year’s line-up includes:

· The all-new Scheduler for CS SoftDent. Designed to give practice administrators a better handle on the interruptive environment of the front desk, the new Scheduler quickly provides easy access to an array of information. It improves office efficiency, productivity and communication, streamlining tasks such as booking new appointments, looking up patient records and updating appointment cards. With customizable tools and appointment books, intelligent and intuitive workflows, and rapid search and display functionality, the CS SoftDent Scheduler offers the most advanced scheduling ever introduced in dentistry. For current CS SoftDent customers with the Advantage Plan, the Scheduler is available as an upgrade free of charge; it is also available for sale as part of CS SoftDent v.15.

· The CS 1600, a multi-use intraoral camera that combines exclusive, patented caries detection technology with Carestream Dental’s industry-leading image quality. With the widest focus range on the market (1mm to infinity), this easy-to-use camera marks a leap forward in dental care; as dentists typically must rely on traditional, more subjective methods of caries detection. This camera features the same unique liquid-lens autofocus technology as Carestream Dental’s 1500 intraoral camera as well as a sophisticated 18-LED illumination system and an optional polarizer filter to reduce glare.

· The compact CS 7600 digital intraoral radiography system, which reinvents imaging plate technology by improving usability, productivity and security. Launched earlier this year at the Chicago Midwinter Meeting, this cost-effective system’s patented intelligent workflow technology prevents plate mix-up and reduces operation time. The CS 7600 is fully automated and as easy to use as film – with all the benefits of digital imaging.

“Carestream Dental understands that efficiency, diagnostic excellence and enhanced patient care are critical components to the success of dental practices,” said Edward Shellard, D.M.D., chief marketing officer and director of business development for Carestream Dental. “The all-new Scheduler for CS SoftDent greatly improves practice administration through intuitive workflows, and the CS 1600 advances caries detection technology into new and meaningful territory. From more advanced scheduling to sophistication in diagnosis, the products we’re showcasing at CDA – South represent our dedication to improving the tools that are available to dental practices.”

Carestream Dental invites all CDA – South attendees to visit booth #502 to get a hands-on demonstration of the CS SoftDent Scheduler and other products during the show.
