Issues

The use of several clinical approaches to improve resin impregnation and the strength of polymer formed by the adhesives as well as to reduce the activation of host-derived proteases can improve the longevity of the resin-dentin bonds.

Increased depth of luting tended to improve the fiber post retention. The bond strength of the self-adhesive resin cement was less affected by aging than the conventional resin cement.

The prognosis of severe cases of external cervical resorption is normally unfavorable due to the injury location and treatment difficulty, and in most cases, the injured tooth is indicated for extraction. It is extremely important to preserve the injured tooth in young patients both for the psychologic aspect and for maintaining function and esthetics.

The proposed technique may be a promising alternative to restorative treatment of teeth with severe dental fluorosis.

Hypoplastic enamel stain in anterior teeth can seriously compromise the esthetics of a smile. Knowing the etiology of the enamel deficiency is essential for determining the most appropriate treatment approach.

Etch-and-rinse adhesive systems can be a better choice for ensuring the long-term success of fissure sealants.

The longevities of resin composite (RC) and glass ionomer (GI) used for cervical restorations were statistically not different, but the clinical performance of the RC was superior to GI in retention, marginal adaptation, and marginal discoloration.

Faster bleaching was observed with Whiteness HP Blue 35 (35% hydrogen peroxide) and tooth sensitivity was similar to that found with the lower concentration Whiteness HP Blue 20 (20% hydrogen peroxide). These results cannot be extrapolated to other in-office 35% hydrogen peroxide gels.

The increased risk of adhesive bond degradation by bleaching should be considered when simplified self-etching adhesives are used. This should be taken into consideration while planning bleaching of adhesively reconstructed teeth.

Silane application is not mandatory for repairing silorane-based resin composite, which can be successfully repaired even with different repair adhesive/materials. However, early signs of nanoleakage can be detected.

Light-curing adhesive and oxalate-type desensitizing agents exhibited better reduction of dentinal fluid flow rate than did protein-precipitation and fluoride-type desensitizing agents based on measurements by a new fluid flow measuring device of subnanoliter scale.

A dentin bonding agent provided greater bond strength to dentin for RMGI than the manufacturers' recommended products.

Ethanol-based chlorhexidine pretreatment is not recommended as a generalized approach to enhance bonding durability.

The application of Nd:YAG laser prior to photopolymerization of adhesive systems in an attempt to create a new bonding layer by dentin/adhesive melting significantly increased the shear bond strength to the dentin substrate.
