Posterior composites: update on cavities and filling techniques

Available online 23 November 2016

 

Abstract

Objectives

The aim of this paper is to examine cavity design for posterior resin composite restorations and to discuss various resin composite filling techniques.

Data

Literature with regard to cavity preparation for amalgam and resin composite restorations has been reviewed. An overview of available bulkfill resin composite systems is provided and a categorization of these systems according to their clinical application and their intended use is outlined.

Sources

A literature search was carried out by the authors in Medline.

Study selection

Pre-defined inclusion criteria based on keywords were included and reviewed.

Conclusions

Minimum cavity preparations are advised for posterior resin composite restorations, preserving the greatest amount of healthy tooth structure. For resin composite restorations only the caries lesion needs to be removed with all remaining tooth structure protected for the bonding process. The anticipated outcome of this philosophy will result in the longer survival of teeth. Newer bulkfill restorative resins allow the operator to complete the restoration in a similar time to the placement of a dental amalgam restoration.

Abstract

An association between vitamin D deficiency and early dental implant failure is not properly verified, but its role in osteoimmunology is discussed. This article illustrates two case reports with vitamin D deficiency and early implant failure. Prior to implant placement, the first patient received crestal bone grafting with autologous material. Both patients received dental implants from different manufacturers in the molar region of the mandible. In the case of bone grafting in the first patient, all implants were placed in a two-stage procedure. All implants had to be removed within 15 days after implant placement. Vitamin D serum levels were measured: Both patients showed a vitamin D deficiency (serum vitamin D level <20 affirm="" after="" and="" between="" both="" clinical="" d="" deficiency="" early="" failure.="" follow="" g="" implant="" in="" l="" must="" nbsp="" osteoimmunology="" p="" patients.="" placement="" prospective="" randomized="" relationship="" successful="" supplementation="" the="" to="" trials="" vitamin="" was="">

Study Shows OraCoat® XyliMelts® Oral Adhering Discs Effectively Treat Acid Reflux




FDA-Approved Clinical Trial Shows that XyliMelts Discs are an Effective Supplement for Treating Many Acid Reflux Symptoms

Bellevue, WA (December 1, 2016) – A recent study revealed that OraCoat® XyliMelts® oral-adhering discs greatly reduce symptoms of heartburn in acid reflux sufferers. The double-blinded, randomized, placebo-controlled study conducted by Peter Van der Ven, DMD, PhD; Jeffrey Burgess, DDS, MSD; and Michael Karcher, BA, PhD candidate; was approved by the Western Institutional Review Board and the U.S. Food and Drug Administration (FDA).

Gastro-esophageal reflux disease (GERD), more commonly known as acid reflux, describes a chronic digestive condition in which an accumulation of stomach acid in the esophagus creates symptoms. Acid reflux affects about 30 percent of the population on a weekly basis and is known to contribute to or cause a number of medical and dental problems including heartburn, sore throat, laryngitis, cough, halitosis, and tooth decay. The condition is also associated with sleep disturbance and can have a negative effect on nighttime comfort and overall quality of life.

The study aimed to prove if XyliMelts, recently rated by a Clinicians Report® survey as the most effective remedy for alleviating dry mouth could produce similar results in treating patients suffering from acid reflux, which is often managed by prescribed and over-the-counter medications that prevent excessive acid production. XyliMelts are formulated from all-natural ingredients commonly used in foods. As tests prove that salivary stimulants can decrease the perception of nighttime dry mouth, tests also suggest increased saliva can diminish nighttime reflux.

Conducted over two weeks, the study analyzed 53 test subjects who provided daily responses to nine questions listing common acid reflux symptoms that might have occurred during the prior night’s sleep. The subjects were separated into two groups, with 26 administered with XyliMelts discs delivered in unmarked packaging, while 27 subjects received the placebo treatment, a water-based gel packaged in an unmarked white tube. Neither the research coordinator nor the subjects were aware which product was being used for data collection.

Test results displayed that both the disc and gel reduced the taste of reflux, heartburn sensation, morning hoarseness, perceived reflux severity, and the number of antacids taken during the night. While both groups demonstrated comparable effectiveness in combating most symptoms, XyliMelts exhibited a profoundly higher improvement rate in lessening heartburn intensity than the placebo gel.*

Overall, the study supports the use of XyliMelts discs as a supplemental remedy for counteracting symptoms during sleep in acid reflux patients.* The discs were well tolerated by all the subjects involved with no adverse reactions reported.

Kerr Launches Harmonize™

Next generation universal composite creates lifelike, long-lasting restorations.

November 30, 2016 Kerr is pleased to announce the launch of Harmonize, a next generation universal composite infused with Adaptive Response Technology (ART), a nanoparticle filler network with features that help dentists achieve a lifelike restoration with more ease and simplicity than ever before. It’s the ART in Harmonize that creates enhanced structural integrity to provide exceptional strength, handling and esthetics.
Harmonize diffuses and reflects light in a similar way as human enamel, leading to an enhanced chameleon effect for better blending. In addition, the particle size and structure is designed to offer superior gloss retention, and easy polishability compared to leading composites.
Harmonize is softer while sculpting, holds its shape without slumping and does so without the stickiness of other composites due to the high loading, spherical shape and rheological modifier of ART.
The ART filler system allows for high loading at 81%, plus a unique reinforced nano-scale filler particle network, which leads to better polymerization, more integration with resin, strength and durability.
Harmonize provides everything doctors expect from a universal composite.
“Harmonize reflects the type of product innovation we are most proud of at Kerr — a superior product that makes the patient happier and the dentist’s day easier,” said Phil Prentice, Vice President of North America for KaVo Kerr. “Our team is committed to the continuous improvement of even our best products and we think our customers will be thrilled with Harmonize.”

Comparison of implant versus tooth-supported zirconia-based single crowns in a split-mouth design: a 4-year clinical follow-up study

Clinical Oral Investigations
, Volume 20, Issue 9, pp 2467–2473

 

Abstract

Objectives

This study aims to evaluate the 4-year clinical performance of tooth versus implant-supported single-unit zirconia crowns (LAVA™) placed on posterior region.

Materials and methods

Twenty-four patients (10 men and 14 women) who had received 48 single crowns (24 implant-supported and 24 tooth-supported) from January 2007 to December 2009, were included. California Dental Association (CDA) quality assessment system, plaque and gingival index scores were used to evaluate the performance of the crowns at baseline and at all follow-up examinations.

Results

During the follow-up period, no fracture of zirconia coping has occurred. Major complication was chipping in three patients that required a new crown fabrication. Except for the failure ones, all crowns in both groups were rated as satisfactory at the follow-up examinations based on the CDA quality assessment criteria. There were no statistically significant differences between tooth and implant-supported crowns in terms of periodontal parameters.

Conclusions

The present 4-year follow-up clinical study demonstrates that single-unit tooth- and implant-supported zirconia crowns have similar prosthetic and periodontal outcomes.

Clinical relevance

Single-unit implant or tooth-supported zirconia crowns may be considered acceptable treatment modalities for restoration of either missing or compromised posterior teeth

A One-Year Evaluation of a Free Fissure Sealant Program

Abstract


Statement of Problem: Pit and fissure sealant therapy has been approved as an effective measure in the prevention of occlusal dental caries. Resin based ma- terials are the most common materials used worldwide. A variety of resin based fissure sealants are produced and used. Most of them have been presented with ideal results in research environment. However, their effectiveness in the real life, especially in a mass application program such as Iran’s oral health reform plan is not clear.
Objectives: To evaluate the longevity of different fissure sealant applied in Iran’s oral health reform plan in Fars Province (south of Iran) after one year.
Materials and Methods: Seven counties were selected. One hundred 6- to
8-year-old school children who had undergone fissure sealant therapy in spring
2015 were randomly selected from each county. Their first molars were exam- ined to evaluate the status of the fissure sealants which were applied one year ago. Data on the type/brand of fissure sealant materials, type and experience of clinicians who applied them, existence of a chair-side assistant, and whether the children were caries-free at the time of fissure sealant application were collected from the existing reports.
Results: Data of 1974 teeth from 598 children were used for the final analysis. The effects of type/brand of the material was significant on the final results and remained significant (p < 0.001) after adjustments for the level of fluoride, urban/rural area, upper/lower jaw, type of clinician who applied the sealant, existence of a chair-side assistant, and child’s gender, age, and being caries-free.
Conclusions: Many factors affect the success rate of a fissure sealant therapy program. The type/brand of the material remained significantly related to the success rate of the fissure sealant even after adjustments for other influencing factors. In this study, ClinproTM  Sealant (3M/ESPE, USA) showed better longevity after one year of application.

New Version of OraCoat® XyliGel® Provides Effective Remedy for Day and Nighttime Dry Mouth

-->


All-Natural and Great Tasting, XyliGel Relieves Dry Mouth Symptoms and Helps Reduce New Cavities

Bellevue, WA (November 15, 2016) – OraCoat, a division of OraHealth Corp., the world leader in the breakthrough technology of oral adhering discs, recently launched a new version of OraCoat® XyliGel®. Formulated with all-natural ingredients, XyliGel coats the mouth with 17% xylitol and oral lubricant to help relieve the symptoms of xerostomia (dry mouth) for those who have very low levels of saliva or prefer to use a gel.

Dry mouth is the subjective sensation of dryness experienced during the daytime and nighttime when an insufficient amount of saliva is produced. While mild or occasional oral dryness occurring especially during sleep is considered normal in healthy individuals, excessive ongoing dryness leads to, among other things, disturbed sleep, difficulty chewing and swallowing, tongue roughness, frequently drinking liquids at night, and rampant tooth decay.

Effective for both daytime and nighttime usage, XyliGel stimulates saliva production and coats the mouth and lips. The gel is pH buffered to the optimal range for the mouth, pH 7.4, and is non-acidic. “It’s our mission to provide the market with safe and effective all-natural oral care remedies,” stated Jeff Haley, Founder, CEO, and Chief Scientist of OraHealth Corporation. “XyliGel not only treats many of the symptoms associated with dry mouth, it also has a favorable vanilla taste for its users to enjoy.”

This soothing gel reduces plaque and new cavities and can decrease long-term tooth decay.* 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.
