Issues

No tooth sensitivity change is detected with the application of partial ceramic indirect restorations. This clinical study could not confirm that immediate dentin sealing is more advantageous than delayed dentin sealing in terms of tooth sensitivity or patient satisfaction with 1 year of clinical service of partial ceramic restorations.

The interaction between different substances on resin composite surfaces is a critical issue in the assessment of the clinical longevity of restorative materials.

This study provides clinicians with insight into the in vitro differences in the performance of commercially available fluoride varnishes. More clinical research is needed to equip dentists with evidence that will help them make better treatment choices.

Highly translucent fully stabilized zirconia can be less fracture resistant than lithium disilicate and partially stabilized zirconia depending on the thickness.

Biaxial flexural strength of tested materials vary with composition and thermocycling significantly decreases their strength. Future clinical studies should evaluate if recommendations based on cavity size and tooth location improve long-term performance.

The use of the LM-Contact Former system, which uses transparent plastic cone-shaped tips, allows obtaining tight proximal contacts in posterior Class II composite resin restorations with a simple technique. Filling the remaining cavity after removing the transparent tip with a bulk-fill flowable resin-based composite decreases the total working time.

Porcelain laminate veneers offer a reliable and successful esthetic treatment, maintaining the long-term gingival health of the surrounding tissues.

Bleaching gels stored at room temperature or kept refrigerated before immediate use showed similar results for color stability, tooth sensitivity, and pH. However, the consistency of the gels when dispensed may be affected by storage temperature.

Chewing gum containing sodium metaphosphate is useful for whitening after eating colored food.

The composition and adhesion strategy of current simplified adhesives may be used for noncarious cervical lesions with minimal dentin sclerosis.

The masking ability of resin composites can change over time and influence long-term performance of multilayered restorations.

The combination of camphorquinone with violet absorption alternative photoinitiators does not improve the depth of cure and, consequently, can increase the polymerization shrinkage stress of bulk-fill composites.

Universal adhesive systems containing phosphate/carboxylic functional methacrylate derivatives are an interesting alternative when bonding to caries-affected dentin.

Violet light produced clinically significant chromatic changes without the use of bleaching gel and potentiated the bleaching effect obtained with a gel containing 17.5% hydrogen peroxide (HP). However, the use of violet light with a gel containing 35% hydrogen peroxide did not affect the final result.

In vitro application of CPP-ACP–containing crèmes for two weeks has a tendency to reduce dentin hypersensitivity by occluding dentinal tubules.

Resin-based composites are able to retain a high-translucency character upon storage.

Hydrofluoric acid etching of yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) ceramic surfaces vitrified with low-fusing glaze withstood thermomechanical cycling. This surface treatment is suitable for improving the bonding stability of resin cements to Y-TZP ceramics.
