Resistance to marginal ridge fracture of class II restorations restored with some bulk-filled resin based composites can be significantly improved by capping with conventional composites and by higher radiant exposure.
Efficacy of a Light-cured Tetracaine-based Anesthetic Gel for Rubber Dam Clamp Placement: A Triple-blind Randomized Clinical Trial
A light-cured anesthetic gel is an excellent alternative to decrease pain when used with a rubber dam clamp to restore noncarious cervical lesions.
Effect of Analgesic Drugs on Tooth Sensitivity Induced by In-office Dental Bleaching: A Systematic Review and Meta-analysis
Clinically, the most commonly observed side effect of bleaching is postoperative sensitivity. Thus, preemptive administration of analgesic drugs can reduce sensitivity and provide more comfort to the patient, without interfering with the results of bleaching.
Efficacy and Adverse Effects of Whitening Dentifrices Compared With Other Products: A Systematic Review and Meta-analysis
When advising patients, dentists should consider the extrinsic stain removal effect of whitening dentifrices that may ultimately result in color change and yet produce adverse effects more often than regular dentifrices.
Effects of Finishing and Polishing Methods on the Surface Roughness and Surface Free Energy of Bulk-fill Resin Composites
The finishing and polishing methods, along with the type of resin composite, significantly affected the surface roughness and surface free energy.
CLINICAL TECHNIQUE/CASE REPORT
Multidisciplinary Management and Pulp Vitality Preservation of a Tooth With Extensive Iatrogenic Furcal Root Perforation and Biologic Width Violation
Knowledge is lacking about the possibility of orthodontically moving a root-repaired tooth whose pulp has maintained vitality. The present case report provides an example of the successful management of a molar tooth with severe iatrogenic damage and multiple negative prognostic factors.
Regardless of the presence of a flowable bulk-fill resin or a short-fiber–reinforced resin under a conventional resin composite, restorations in class II cavities restored with bulk-fill resins showed satisfactory and similar clinical performance.
The surface gloss of esthetic restorations is a determinant in accurately mimicking dental structures in terms of tooth proportion and visual perception. Restorative protocol choices might be guided by understanding the threshold of perceptibility and acceptability of gloss differences.
Volumetric Cuspal Deflection of Premolars Restored With Different Paste-like Bulk-fill Resin Composites Evaluated by Microcomputed Tomography
The use of paste-like bulk-fill composites for class II MOD cavities reduces cuspal deflection compared to the paste-like conventional resin composite.
Clinical Evaluation of a Chairside Amalgam Separator to Meet Environmental Protection Agency Dental Wastewater Regulatory Compliance
US dental practices that routinely place and remove amalgam restorations are now required to use an amalgam separator with ≥95% efficiency. This independent study evaluated and characterized the performance of a chairside amalgam separator, demonstrating that minimum standards for compliance can be met.
CEREC BlueCam and CEREC OmniCam CAD-CAM systems were able to fabricate onlays with clinically acceptable marginal discrepancies, below 100 μm; however, the Press system presented superior internal and marginal adaptation.
Dynamic Viscoelastic Characterization of Bulk-fill Resin-based Composites and Their Conventional Counterparts
The viscoelastic properties of bulk-fill resin-based composites (RBCs) were affected by aqueous solutions and are often inferior to their conventional counterparts. The clinical use of conventional RBCs are generally preferred over bulk-fill materials for high-stress-bearing situations.
Influence of Application Time on Dentin Bond Performance in Different Etching Modes of Universal Adhesives
Although reduced application time of dentin appears to be acceptable for some universal adhesives, care should be taken when using universal adhesives that recommend applying the adhesive with active motion, regardless of the etching mode.
Effect of pH Cycling Followed by Simulated Toothbrushing on the Surface Roughness and Bacterial Adhesion of Bulk-fill Composite Resins
Toothbrushing slightly increases the surface degradation of conventional and bulk-fill resins initially caused by a cariogenic challenge. However, these superficial changes do not suggest significant differences in bacterial adhesion on the composite resin surfaces.
Influence of CAD/CAM Fabrication and Sintering Procedures on the Fracture Load of Full-Contour Monolithic Zirconia Crowns as a Function of Material Thickness
Chairside sintering might be a suitable procedure to produce zirconia restorations with clinically adequate fracture loading values for specific restoration thicknesses.
