Cement-associated peri-implant mucositis. A 1-year follow-up after excess cement removal on the peri-implant tissue of dental implants

Clinical Implant Dentistry and Related Research
Online Version of Record published before inclusion in an issue

Abstract

Background

Methacrylate-based cements seem to promote peri-implant tissue inflammation even in the absence of excess cement.

Purpose

The present study deals with the question of whether the removal of methacrylate cement from the peri-implant sulcus will lead to peri-implant tissues free of inflammation on a 1-year follow-up basis.

Material and Methods

Implant supported suprastructures that had been in the mouth for at least 3.5 years either cemented with methacrylate (premier implant cement [PIC]) or zinc eugenol (temp bond [TB]) cement were compared. All superstructures in 33 patients with a total of 61 implants (35 with PIC and 26 with TB) were removed and excess cement, bleeding on probing (BOP), suppurationen and probing depth were documented. Excess cement found was removed, and in all cases the suprastructure was recemented with TB. Patients were followed up after 4 weeks (F1) and 1 year (F2).

Results

Excess cement was found around 60% of the implants with PIC. No excess cement was found around implants with TB. At the time of revision therapy, BOP was found around 100% of the implants with PIC and excess cement (PIC+), 93% around implants with PIC but no excess cement (PIC−), and around 42% of the TB-cemented implants (Chi-squared P < .01). Suppuration was observed in 86% of the PIC+ implants, in 14% of the PIC− implants and in 0% of the TB implants (Chi-squared P < .01). At the time of both F1 and F2, the inflammation parameters, that is BOP and suppuration, on implant level were significantly reduced in the PIC+ cases (McNemar‘s test P < .01). For PIC−, BOP was significantly reduced at both points in time (P < .05). For TB no differences were found. Probing depth at F2 had significantly decreased in all groups (t test P < .05).

Conclusion

The removal of excess cement and recementation with TB had an anti-inflammatory effect on the peri-implant tissues after 1 year.

Enamel remineralization effect of a dentifrice containing calcium sodium phosphosilicate: an optical coherence tomography observation.

Acta Odontol Scand. 2017 Jan 16:1-10. doi: 10.1080/00016357.2016.1277588. [Epub ahead of print]

Abstract

OBJECTIVE:

The purpose of this study was to examine the effects of a dentifrice containing 5% calcium sodium phosphosilicate (CSP) on the remineralization of the enamel using optical coherence tomography (OCT).

MATERIALS AND METHODS:

Bovine incisors were sliced and shaped in a rectangular form. One group of five specimens was treated with undersaturated 0.1 M lactic acid buffer solution (pH 4.75) for 10 min and then placed in artificial saliva (pH 7.0) (De group). Other specimens were stored in solutions of toothpaste containing CSP for 10 min, followed by 10-min immersion in the lactic acid buffer solution twice a day before storage in artificial saliva (CSP group). An additional group was stored in only artificial saliva (control group). OCT imaging on the selected location of the enamel surface was performed. The peak intensity and width at 1/e2 were recorded in each of the six areas on the sample and averaged, and the sample size of each group was six. The integrated value in units (dB × μm) was calculated in the area of peak intensity. The data for each group was subjected to one-way repeated-measures ANOVA and Tukey HSD tests (α = 0.05).

RESULTS:

The changes in integrated values of each group were different. A slight but significant increase in the integrated value was observed in the control group, whereas a slight but significant decrease in the value was observed the De group. Integrated values increased in the CSP group.

CONCLUSIONS:

Remineralization occurred upon immersion in the toothpaste containing CSP.

In vitro effects of hyaluronic acid on human periodontal ligament cells

BMC Oral HealthBMC series – open, inclusive and trusted201717:44
DOI: 10.1186/s12903-017-0341-1
Received: 2 August 2016
Accepted: 11 January 2017
Published: 16 January 2017

Abstract

Background

Hyaluronic acid (HA) has been reported to have a positive effect on periodontal wound healing following nonsurgical and surgical therapy. However, to date, a few basic in vitro studies have been reported to investigating the potential of HA on human periodontal ligament (PDL) cell regeneration. Therefore, the aim of this study was to investigate the effect of HA on PDL cell compatibility, proliferation, and differentiation in vitro.

Methods

Either non-cross-linked (HA_ncl) or cross-linked (HA_cl) HA was investigated. Human PDL cells were seeded in 7 conditions as follows (1) Control tissue culture plastic (TCP) (2) dilution of HA_ncl (1:100), (3) dilution of HA_ncl (1:10), 4) HA_ncl directly coated onto TCP, (5) dilution of HA_cl (1:100), 6) dilution of HA_cl (1:10) and (7) HA_cl directly coated onto TCP. Samples were then investigated for cell viability using a live/dead assay, an inflammatory reaction using real-time PCR and ELISA for MMP2, IL-1 and cell proliferation via an MTS assay. Furthermore, the osteogenic potential of PDL cells was assessed by alkaline phosphatase(ALP) activity, collagen1(COL1) and osteocalcin(OCN) immunostaining, alizarin red staining, and real-time PCR for genes encoding Runx2, COL1, ALP, and OCN.

Results

Both HA_ncl and HA_cl showed high PDL cell viability (greater than 90%) irrespective of the culturing conditions. Furthermore, no significant difference in both mRNA and protein levels of proinflammatory cytokines, including MMP2 and IL-1 expression was observed. Both diluted HA_ncl and HA_cl significantly increased cell numbers compared to the controlled TCP samples at 3 and 5 days. HA_ncl and HA_cl in standard cell growth media significantly decreased ALP staining, COL1 immunostaining and down-regulated early osteogenic differentiation, including Runx2, COL1, and OCN mRNA levels when compared to control samples. When osteogenic differentiation medium (ODM) was added, interestingly, the expression of early osteogenic markers increased by demonstrating higher levels of COL1 and ALP expression; especially in HA 1:10 diluted condition. Late stage osteogenic markers remained inhibited.

Conclusions

Both non-cross-linked and cross-linked HA maintained high PDL cell viability, increased proliferation, and early osteogenic differentiation. However, HA was consistently associated with a significant decrease in late osteogenic differentiation of primary human PDL cells. Future in vitro and animal research is necessary to further characterize the effect of HA on periodontal regeneration.

OraCoat® Products Help Orthodontic Patients With Mouth Sores and Caries




OraCoat XyliGel® and H-B12 Melts® Provide Patients Dealing with Painful Brace Sores and Possible Tooth Decay with a Viable Treatment Option

Bellevue, WA (January 17, 2017) – OraCoat®, a division of OraHealth Corp., the world leader in the breakthrough technology of oral adhering discs, produces a line of all-natural products conducive for the use of orthodontic patients suffering from brace irritation and difficulty brushing their teeth with braces.

Pediatric patients, and brace wearers in general, often experience mouth sores as a result of the brackets rubbing against the inside of the cheeks, creating exasperating and often painful mouth sores. Although home remedies such as rinsing with salt water and avoiding acidic foods can help allay these symptoms, for many patients, the sores persist.

OraCoat H-B12 Melts® provide long-lasting pain relief and healing support for mouth sores, cuts, wounds, brace irritation, and mouth ulcers. With active ingredients of hyaluronan and bioactive B12, these safe-to-use adhering discs support a healthy mouth lining and work harmoniously with braces and other orthodontic appliances. Moreover, pediatric brace wearers also run the risk of suffering tooth decay as a result of food and plaque getting trapped between the brackets and wires. To prevent permanent damage to tooth enamel, in addition to proper cleaning, OraCoat XyliGel® neutralizes acids in the mouth with a buffered pH of 7.4 and holds 17% xylitol against the teeth to reduce plaque formation.

Effective for both daytime and nighttime use, XyliGel stimulates saliva production and coats the mouth and lips to relieve dry mouth. This soothing gel reduces plaque and acidity on the teeth.* XyliGel is the newest member of the OraCoat brand family of products which includes XyliMelts® oral adhering discs, rated by a Clinicians Report® survey as the most effective remedy for combating dry mouth.

DentalEZ® Donates Massive Amount of Equipment, Supplies to Project Chimps Organization




Contribution Will Provide Complete Dental Care Facility for
the Organization’s New Location

Malvern, PA (January 10, 2017) – For its latest philanthropic endeavor, DentalEZ®, a supplier of integrated products and services for dental health professionals worldwide, recently donated a full shipment of dental supplies and equipment to Project Chimps, a rescue organization dedicated to the lifetime sanctuary care of hundreds of captive chimpanzees.

Specifically, the Company donated various dental products, and operatory and utility room equipment to Project Chimps’ new northern Georgia sanctuary including NevinLabs steel cabinets, DentalEZ® delivery units and operatory lights, StarDental® handpieces, and RAMVAC vacuums and compressors. Because of the Company’s generous donation, the new dental facility will now have all components needed for complete and optimal dental care of the rescued animals.

Peter Volk, Territory Sales Manager for DentalEZ is heading the mission along with Southern Region Manager, Chuck Seeger, and Jason Hodkowski, Senior Institutional Sales Manager. The team is currently working with the company to create the dental facility. “It is interesting because as dental professionals our focus is almost always on our human patients,” remarked Volk. “What most people don’t think about is that all of the animals that they only see on Animal Planet or at the zoo need dental care. Once in a captive environment these animals need to receive all of the preventive care that we humans are accustomed to.”

A recent transfer carried out by Project Chimps prompted the charitable donation by DentalEZ, as well as widespread national attention. Nine chimpanzees once used as research animals at the New Iberia Research Center in Louisiana were just relocated to the new Project Chimps refuge, hundreds of miles from their former home in a lab where they were used as subjects in biomedical testing.

Workers with the non-profit organization transported all nine animals and now Project Chimps sanctuary, located in Morganton, Georgia, is their new home, a sprawling preserve where over 200 chimps will eventually roam free. The 236-acre sanctuary is located along a temperate rainforest, with rolling hills and a lush, green landscape. In addition to office buildings, a full veterinary clinic, and an upscale kitchen designed by celebrity chef Rachael Ray, there are currently four "villas" that can house 10-15 chimps each, and one larger group building that can house two groups of 10-15 chimps. 

“It’s a very rewarding feeling to know that we are providing the medical and dental equipment to chimps that, up to this point, have spent most if not all of their lives in a research laboratory,” continued Volk. “As a DentalEZ representative, it is important that we give back not only to the people in our community, but also to those that do not have a voice. It is our calling as dental professionals to make sure that everyone, both human and animal, are treated with the utmost care and respect.”

In 2015, all chimpanzees were designated an endangered species, marking the end of privately funded research on chimpanzees in the US. Chimps are considered the smartest primate and the closest relatives to humans, which is why the New Iberia Research Center in Louisiana has used 220 of them for medical testing.

The opening of the new Project Chimps sanctuary follows a steady shift away from controversial biomedical research on chimpanzees across the country. The National Institutes of Health (NIH) began significantly phasing out its funding of federal research on chimps in 2013, and announced the retirement of its 50 remaining chimpanzees in November 2015.

NIH also ended its research support for chimps but did not own approximately 360 remaining around the US. Now the private institutions that own them, like the New Iberia Research Center, are following suit. However, due to limited space at existing sanctuaries such as Chimp Haven in Louisiana and Save the Chimps in Florida, the creation of new refuges like Project Chimps is crucial.

About Project Chimps

Project Chimps was founded in late 2014 by a “super group” of chimpanzee, nonprofit, philanthropic, and legal experts to solve the critical question of what would happen to the hundreds of chimps still left in private biomedical research. Primatologists and professionals from all over the country left their current roles and signed on to work for Project Chimps, a nonprofit organization that is making unprecedented advances for captive chimpanzees. Through relationship-building, collaboration, and tenacity, Project Chimps was able to come to an agreement with the University of Louisiana’s New Iberia Research Center. They agreed to let Project Chimps have all of their remaining chimpanzees and provide them with lifetime sanctuary care. This decision is unprecedented and shows what positive collaboration can do for the betterment of others, in this case: chimpanzees. For more information, please visit www.projectchimps.org.

OraVital’s 2017 KOL Access Webinar Series


Dr. Bradley Bale & Dr. Amy Doneen Kick-Off
OraVital’s 2017 KOL Access Webinar Series

The Presenters Will Review the Findings of Their British Medical Journal Paper That Shows High Risk Periodontal Pathogens
are a Contributory Cause of Arterial Disease

Toronto, CA – January 10, 2017 – OraVital Inc., The Oral Infection Experts™, will be kicking off its 2017 KOL Access Webinar Series, with two of the leading pioneers of the oral-systemic health movement; Dr. Bradley Bale and Dr. Amy Doneen, who are the authors of the best-selling book, “Beat the Heart Attack Gene”

Long time advocates of the critical role that dental professionals play in the prevention of heart attacks and strokes, Drs. Bale and Doneen recently co-authored an article with Dr. David Vigerust that will be published in print in the prestigious Postgraduate Medical Journal and was published online ahead of print by the British Medical Journal (BMJ) entitled, “High-Risk Periodontal Pathogens Contribute to the Pathogenesis of Atherosclerosis.”

According to OraVital CEO, Dr. Jim Hyland, “This is a ground-breaking report that further validates the oral-systemic health link in general and more specifically, the perio-cardio link. The PGMJ /BMJ manuscript clearly states, ‘periodontal disease due to high risk pathogens is a cause of arterial disease.’ Now more than ever, dental clinicians can and should strengthen their commitment identifying and managing this form of periodontal disease.”  

-more-
Because of the complexity of the topic and because atherosclerosis is the largest cause of death and disability in North America, Drs. Bale and Doneen have been invited to present their findings in a two-part CE webinar. The schedule is as follows:
·       Thursday, 2/9/17 l 8:30 PM EST: “High-Risk Periodontal Pathogens Contribute to the Pathogenesis of Atherosclerosis.” l Presented by Bradley Field Bale, M.D. l 1 CEU
According to Dr. Bale, “Periodontal disease due to high risk pathogens must be considered a contributory cause of arterial disease.  Dr. Bale will present the science which supports this landmark statement.  Considering this knowledge, the dental community has a significant opportunity to favorably impact the number one cause of death and disability by effectively managing this type of periodontal disease.”
·       Thursday, 3/9/17 l 8:30 PM EST: “Integrating the Science of Oral/Systemic Health into Clinical Practice.” l Presented by Amy Doneen, DNP, ARNP l 1 CEU

“It is necessary to respect the clinical context for which the information outlined in the recent BMJ study can be applied to the clinical dental arena,” explained Dr. Doneen. “What’s more, lines of communication must be created between medicine and dentistry that can clearly articulate the importance of understanding the oral pathogen burden as it relates to the vascular health of the individual patient.”  

For more information on the 2017 KOL Access Webinar Series, sponsored by OraVital® and how to register for each upcoming webinar, visit https://www.oravital.com/KOL2017. Dental industry thought leaders wishing to participate in future KOL Access Webinars are invited to send an abstract to Michael@Ventriello.com.

Evaluation of pit-and-fissure sealants placed with four different bonding protocols: a randomized clinical trial

Authors







  •  

    Abstract



    Background

    Application of adhesive after acid etching may increase the retention of pit-and-fissure sealants and improve clinical effectiveness.

    Aims

    To clinically evaluate the retention, marginal discoloration and caries incidence of pit-and-fissure sealants applied using four bonding protocols: conventional acid etching, etch-and-rinse adhesive, multimode universal adhesive and self-etch adhesive used after acid etching.

    Design

    In this split-mouth design study, the four adhesive protocols were randomly assigned to the four erupted, non-carious first permanent molars and involved 52 patients between 6 and 10 years of age. The sealants were evaluated at 3-, 6- and 12-month intervals. Statistical analysis was carried out using Friedman test and Kruskal–Wallis test.

    Results

    At 12 months, the retention rate was maximum in etch-and-rinse and universal adhesive groups (77.1%) followed by self-etch adhesive (58.3%) and conventional acid etching group (45.8%). Dental caries was observed only in one tooth, and marginal discoloration was found to be the highest in conventional group and least in etch-and-rinse group.

    Conclusions

    Use of adhesives during pit-and-fissure sealant application does not significantly enhance sealant retention nor decrease marginal discoloration. Etch-and-rinse adhesive is advantageous only at short term.

    The evaluation of trustworthiness to identify health insurance fraud in dentistry

    Available online 27 December 2016

    Highlights

    The Economist says 10% of health care expenditure ($272 billion) was wasted on fraudulent claims in 2012.
    Previous studies aimed at other types of fraud are inadequate for solving cross-dentist health insurance fraud.
    We devise a social-network-based risk evaluation to detect fraudulent claims in dentistry.
    By experiment, using real-world or artificial data, our method can effectively identify undetected frauds in the past in dentistry claims data.
    Integrating our method with previous research can provide higher accuracy.

    Abstract

    Objective

    According to the investigations of the U.S. Government Accountability Office (GAO), health insurance fraud has caused an enormous pecuniary loss in the U.S. In Taiwan, in dentistry the problem is getting worse if dentists (authorized entities) file fraudulent claims. Several methods have been developed to solve health insurance fraud; however, these methods are like a rule-based mechanism. Without exploring the behavior patterns, these methods are time-consuming and ineffective; in addition, they are inadequate for managing the fraudulent dentists.

    Methods

    Based on social network theory, we develop an evaluation approach to solve the problem of cross-dentist fraud. The trustworthiness score of a dentist is calculated based upon the amount and type of dental operations performed on the same patient and the same tooth by that dentist and other dentists.

    Results

    The simulation provides the following evidence. (1) This specific type of fraud can be identified effectively using our evaluation approach. (2) A retrospective study for the claims is also performed. (3) The proposed method is effective in identifying the fraudulent dentists.

    Conclusions

    We provide a new direction for investigating the genuineness of claims data. If the insurer can detect fraudulent dentists using the traditional method and the proposed method simultaneously, the detection will be more transparent and ultimately reduce the losses caused by fraudulent claims.

    Adjunctive efficacy of probiotics in the treatment of experimental peri-implant-mucositis with mechanical and photodynamic therapy: a randomized, cross-over clinical trial.

    J Clin Periodontol. 2016 Dec 29. doi: 10.1111/jcpe.12689. [Epub ahead of print]

    Abstract

    AIM:

    to evaluate the adjunctive clinical efficacy of probiotics in the treatment of peri-implant mucositis (p-iM) with professionally administered plaque removal (PAPR) and photodynamic therapy (PDT).

    MATERIALS AND METHODS:

    Following p-iM induction, patients underwent PAPR+PDT and were randomly assigned to receive the professional and home-based administration of probiotics (Lactobacillus plantarum and Lactobacillus brevis) (test treatment) or placebo preparation (control treatment) according to a cross-over design. Clinical parameters were assessed at 6 sites for each implant before as well as at 2 and 6 weeks after professional treatment administration.

    RESULTS:

    Twenty patients contributing 1 dental implant each were included. Immediately before treatment and at 6 weeks, the median number of sites with bleeding on probing (BoP+) sites per implant unit was 4 (3-6) and 2 (0-2) (p< 0.001), respectively, for test treatment, and 3.5 (2-4) and 2 (0-3) (p= 0.03), respectively, for control treatment. No significant difference in clinical outcomes was observed between treatment groups.

    CONCLUSION: The combination of PAPR and PDT either alone or associated with probiotics determined a significant reduction of the number of BoP+ sites at 2 and 6 weeks around implants with p-iM. The adjunctive use of probiotics did not significantly enhance the clinical outcomes of PAPR + PDT.

    Treatment Outcomes of Mineral Trioxide Aggregate Pulpotomy in Vital Permanent Teeth with Carious Pulp Exposure: The Retrospective Study

    Journal of Endodontics

     

    Abstract

    Introduction

    This study aimed to illustrate the treatment outcomes of mineral trioxide aggregate (MTA) pulpotomy in vital permanent teeth with carious pulp exposure.

    Methods

    MTA pulpotomy was performed in 66 vital permanent teeth with carious pulp exposure including teeth with signs and symptoms of irreversible pulpitis and the presence of periapical radiolucency. Patients were assessed for clinical and radiographic outcomes by 2 examiners. The relationship between treatment outcomes and factors was analyzed by means of univariate analysis and binary logistic regression.

    Results

    Fifty patients (a total of 55 teeth) attended the follow-up examination. The age of the patients ranged from 7–68 years old (mean = 29 years old). For the follow-up period as far as 62 months, 48 teeth showed successful outcomes (success rate = 87.3%). Teeth with clinical signs of irreversible pulpitis and the presence of periapical radiolucency could be treated successfully by MTA pulpotomy with success rates of 84% and 76%, respectively.Three of 7 failed cases required pulpectomy after MTA pulpotomy to relieve painful pulpitis. Four other failed cases were asymptomatic, and failure was detected from radiographic examination. The relationship between treatment outcomes and treatment factors could not be detected statistically.

    Conclusions

    Teeth with carious pulp exposure can be treated successfully by MTA pulpotomy. Clinical signs of irreversible pulpitis and the presence of periapical radiolucency should not be considered as a contraindication for pulpotomy.

    Tooth eruption and obesity in 12-year-old children


    Abstract

    Background/purpose

    There is a need to comprehensively investigate the relationship between tooth eruption and obesity. The study aimed to investigate the relationship between erupted permanent tooth number and obesity among 12-year-old children in a population-based study.

    Materials and methods

    A random sample of 806 12-year-old schoolchildren in Hong Kong was recruited. Oral examinations were conducted and the eruption status of the permanent teeth was assessed. Body height, body weight, waist circumference (WC), hip circumference, and triceps skinfold thickness (TRSKF) were measured to assess the adiposity statuses [weight-height ratio (W/H) and body mass index (BMI) for general obesity; WC and waist-hip ratio (WHR) for central obesity; and TRSKF for peripheral obesity]. The relationships between erupted permanent tooth number and adiposity statuses were examined in bivariate analysis and analysis of covariance.

    Results

    The response rate was 82.9% (n = 668/806). Three hundred and forty-six (50.9%) children had 28 teeth erupted. Second molars had the highest rate of noneruption (17.5–35.8%). The mean number and standard deviation (SD) of erupted permanent tooth were 26.4 (2.4). The mean value and SD were 31.1 (6.3) for W/H, 19.8 (3.7) for BMI, 70.4 (9.4) for WC, 0.82 (0.06) for WHR, and 11.8 (4.5) for TRSKF, respectively. After accounting for sociodemographic factors, analysis of covariance identified that W/H, BMI, WC, and WHR were positively associated with the number of erupted permanent teeth (P < 0.01).

    Conclusion

    Erupted permanent tooth number was positively associated with obesity (general and central) among a population-based sample of 12-year-old children in Hong Kong.
