Polymerization shrinkage of conventional resin-based composites can cause cuspal deflection and be associated with enamel cracking, cusp or tooth fracture, and changes in occlusion. High-viscosity bulk-fill resin composites may produce less cuspal deflection than a conventional incrementally placed resin composite.
Assessing the Appearance and Fluorescence of Resin-Infiltrated White Spot Lesions With Caries Detection Devices
Fluorescent camera caries detectors can be used to assess the effectiveness of resin infiltration in improving the optic properties of white spot lesions. Clinicians can use a fluorescent camera to demonstrate early lesions to patients.
Real-time Light Transmittance Monitoring for Determining Polymerization Completeness of Conventional and Bulk Fill Dental Composites
Short curing times of 10-20 seconds may be insufficient for an optimal polymerization, especially under nonideal clinical conditions (eg, variable distance and angulation of the curing unit tip).
Replacement of a Missing Maxillary Central Incisor Using a Direct Fiber-Reinforced Fixed Dental Prosthesis: A Case Report
Fiber-reinforced fixed dental prosthesis using the direct restorative technique may be accomplished with ideal contours and tooth morphology when a proper material selection and a step-by-step protocol is followed. This option becomes useful as an interim restoration in many clinical situations.
Does Finishing and Polishing of Restorative Materials Affect Bacterial Adhesion and Biofilm Formation? A Systematic Review
A polished/smooth surface is mandatory for maintaining clinical health of restored teeth. However, this review depicts the absence of reliable data that characterize and elucidate the mechanism related to the effect of surface properties on bacterial adhesion/biofilm formation.
CLINICAL TECHNIQUE/CASE REPORT
Repairing defective composite resin and amalgam restorations is a safe and effective treatment that might increase restoration longevity.
A Clinical Study on the Effect of Injection Sites on Efficacy of Anesthesia and Pulpal Blood Flow in Carious Teeth
Infiltration anesthesia over the midpoint of the line connecting the root apexes of two adjacent teeth causes less reduction of pulpal blood flow.
Use of a hybrid light (laser/LED) for in-office dental bleaching shows the same degree of color change with lower bleaching time and sensitivity compared with conventional in-office bleaching.
Thanks to new composite resins and dental ceramics, an excellent esthetic may be clinically combined with outstanding functional features in terms of their wear behavior, which proved to be very similar to that of the well-known traditional gold alloys.
Effect of Vital Tooth Bleaching on Surface Roughness and Streptococcal Biofilm Formation on Direct Tooth-Colored Restorative Materials
Vital tooth bleaching with 10% carbamide peroxide or 40% hydrogen peroxide increased both the surface roughness and biofilm formation on resin composite and resin-modified glass ionomer cement restorative materials, suggesting that existing restorations should be polished or replaced after bleaching.
The use of NaOCl at the interface of resin and eroded dentin may be a viable alternative to minimize the degradation of the etch-and-rinse and self-etch resin−dentin interfaces.
Effect of Light Activation of Pulp-Capping Materials and Resin Composite on Dentin Deformation and the Pulp Temperature Change
Light curing of pulp-capping materials caused deformation of pulpal dentin and increased pulpal temperature by light curing and exotherm effects. The use of Vitrebond or Ultra-Blend Plus in deep cavities resulted in better performance through a combination of high degree of cure, lower temperature, and dentin strain.
The Effects of Cavity Preparation and Composite Resin on Bond Strength and Stress Distribution Using the Microtensile Bond Test
The biomechanical performance of composite resins is strongly influenced by the type of cavity preparation used. Using flat surface preparation to test different composite types may underestimate the effect of C-factor, stress, and shrinkage of composite resins.
Effect of Finishing and Polishing on Roughness and Gloss of Lithium Disilicate and Lithium Silicate Zirconia Reinforced Glass Ceramic for CAD/CAM Systems
Silica-based glass ceramics restorations achieve clinically acceptable, enamel-like roughness and gloss by either glazing or manual finishing and polishing. The latter can be considered an adequate procedure, comparable to furnace-based restorations, and this is noteworthy for chairside monolithic restorations.
A Novel Enamel and Dentin Etching Protocol Using α-hydroxy Glycolic Acid: Surface Property, Etching Pattern, and Bond Strength Studies
Glycolic acid is a mild etchant that effectively etches enamel and dentin surfaces, a necessary step to successfully placing dental adhesive restorations.
