Physical Properties of Nanohybrid and Microhybrid Resin Composites Subjected to an Acidic Environment: A Laboratory Study
Consumption of acidic beverages does not alter the color stability nor decrease the hardness of resin composites in comparison with nonacidic beverages. In general, the type of materials and polishing methods are important factors in the maintenance of resin composites.
Bioactive Materials Subjected to Erosion/Abrasion and Their Influence on Dental Tissues
When restorations are needed in patients with high risk of erosive tooth wear, resin-modified GICs may be considered an alternative. Although they are susceptible to wear under erosion/abrasion, they are capable of reducing enamel loss adjacent to the restorative material.
Do Tooth- and Cavity-related Aspects of Noncarious Cervical Lesions Affect the Retention of Resin Composite Restorations in Adults? A Systematic Review and Meta-analysis
Recognizing the effects related to the teeth and cavities of NCCLs that are relevant to the success of the restoration is important, as clinicians must be aware of them during the procedure and follow-up of the patients.
Effect of Curing Light and Exposure Time on the Polymerization of Bulk-Fill Resin-Based Composites in Molar Teeth
Light curing a molar bulk-fill mesio-occluso-distal restoration from a single position at the center of the occlusal surface may result in inadequate photopolymerization of the resin-based composite at the bottom of the proximal boxes.
Wear Properties of Different Additive Restorative Materials Used for Onlay/Overlay Posterior Restorations
Recently introduced indirect resin composites and dental ceramics show a wear behavior similar to traditional gold alloys. The present laboratory findings support a successful use of such new materials on load-bearing occlusal surfaces of posterior teeth, even for extensive occlusal rehabilitations.
CLINICAL TECHNIQUE/CASE REPORT
A Conservative Approach to Ceramic Veneers: A Case Report
For anterior ceramic veneers, a predictable result can be obtained through a proper diagnostic mock-up followed by the use of reduction guides in tooth preparation. In addition, isolation with a rubber dam is crucial for the success of adhesive protocols.
An Improved Direct Injection Technique With Flowable Composites. A Digital Workflow Case Report
Anterior dental restorations often involve difficult and time-consuming procedures. An improved direct injection technique using a digital workflow in the restoration of anterior teeth can be an alternative to save clinical time and yield a predictable and esthetic outcome.
CLINICAL RESEARCH
Clinical Performance of a Glass Hybrid Restorative in Extended Size Class II Cavities
The clinical effectiveness of a glass hybrid restorative system was as acceptable as composite resin in large size Class II cavities subsequent to 24-month evaluation.
The Dental Amalgam Phasedown in New Zealand: A 20-year Trend
This research reports how amalgam has reached the verge of elimination from clinical service in New Zealand's dental education system. New Zealand's national school of dentistry is prepared for New Zealand's expected ratification of the Minamata Convention on Mercury.
Literature Review
Effect of Bleaching Gel Concentration on Tooth Color and Sensitivity: A Systematic Review and Meta-analysis
The use of low-concentration bleaching gels will promote in the patient a favorable whitening effect compared to high concentrations while at the same time being responsible for a lower dental sensitivity, promoting patient comfort.
LABORATORY RESEARCH
Endodontic Access Effect on Full Contour Zirconia and Lithium Disilicate Failure Resistance
Although more investigation is required, replacing adhesively luted, all-ceramic yttria-stabilized zirconium dioxide and lithium disilicate crowns may not be required after endodontic access.
Effects of Bioactive Agents on Dentin Mineralization Kinetics After Dentin Bleaching
Dental bleaching treatment significantly decreases dentin bond strength. Bleached dentin remineralization treatment seems to effectively promote mineral formation, increase dentin bond strengths, and improve dentin's chemical affinity with adhesive monomers.
Influence of Light-curing Distances on Microflexural Strength of Two Resin-based Composites
Clinicians may light cure thin layers of the resin-based composites explored at 2-mm and 8-mm distances without significantly affecting the microflexural strength.
How Do the Etching Mode and Thermomechanical Loading Influence the Marginal Integrity of Universal Adhesives?
Adhese Universal exhibited better marginal integrity than Peak Universal, and for both adhesives, thermomechanical loading degraded the bonding durability, particularly for nonetched enamel and pre-etched dentin.
Does Diamond Stone Grinding Change the Surface Characteristics and Flexural Strength of Monolithic Zirconia?
Dentists commonly need to perform grinding procedures to gain space when adapting a prosthesis; however, this grinding may induce damage to the surface. Thus, it is important to perform grinding that does not impair the properties, and the best way is without irrigation for conventional and monolithic zirconias.
Influence of Multiple Peak Light-emitting-diode Curing Unit Beam Homogenization Tips on Microhardness of Resin Composites
Lack of beam homogeneity in multiwave light-curing units might produce inadequate polymerization in composite restorations, causing a decreased microhardness that lessens clinical longevity of a restoration. Light curing units producing homogeneous beams are recommended.
