Issues

Adhesive cementation using adhesive resin cements promotes higher crown retention when compared with self-adhesive, resin-modified ionomer, and zinc phosphate cements. Conditioning with tribosilicatization and application of a thin low-fusing glass porcelain layer plus silanization on the intaglio surface of an yttria-stabilized polycrystalline tetragonal zirconia crown seems to improve crown retention.

Accelerated aging induced perceptible color change in a nanofilled resin composite whether or not matrix metalloproteinase inhibitors were used.

Professionally applied in-office whitening, professionally dispensed patient-applied home whitening, and the use of an over-the-counter product are effective in changing tooth color toward a lighter shade, whereas do-it-yourself whitening is not an effective tooth whitening modality.

Knowing the details of ultramorphological features of the dentin-resin interface can enhance the proper selection of simplified self-etch adhesives when used in clinical practice.

Bond strength to dentin decreases with time because of the hydrolytic degradation of the hybrid layer components dentin collagen and adhesive resin. Inhibition of enzymes responsible for the collagen degradation may improve the bond strength durability.

Successful resin composite restorations can be achieved when a careful restorative technique is employed. Use of a sectional matrix band and elastic ring helps achieve a tight proximal contact, and the centripetal restorative technique can help to obtain contour and anatomy, minimizing the use of rotary instruments during the finishing procedures.

White developmental enamel lesions can be successfully masked using the resin infiltration technique, resulting in a satisfactory esthetic appearance of affected teeth.

Repair of amalgam restorations is a safe and effective treatment to increase the restorations' longevity with minimal intervention dentistry.

Carbodiimide (EDC) and glutaraldehyde are cross-linking agents capable of increasing resin-dentin bond durability. This study showed that these substances might be safely applied on acid-etched dentin since they have no transdentinal cytotoxic effects on cultured odontoblast-like cells.

Single Bond Universal and All-Bond Universal significantly improved the bond strength of resin cement to zirconia ceramic compared with Alloy Primer.

The combined use of air-abrasion and zirconia primer should be recommended for strong and durable bonding between yttria-tetragonal zirconia polycrystal and self-adhesive resin cement.

During in office bleaching techniques, the reapplication of products is not necessary.

Matrix metalloproteinase (MMP) inhibitors prevented bond strength loss of an etch-and-rinse adhesive over time. Bond strength of a self-etching adhesive was not significantly reduced with 9 months of aging; thus, MMP inhibitors did not show a significant effect.

The surface free energy and dentin bond strength of the dual-cure core build-up systems tested in this study were affected by the light intensity of the curing unit. When using dual-cure core build-up systems, practitioners need to consider the light intensity of the curing unit to achieve the optimal bond strength.

This study showed that 35% hydrogen peroxide gel exhibited higher whitening potential compared with 20% gel, without intensifying the adverse effects on enamel surface microhardness.

Determining the optimal irradiation parameters of odontoblast-like cell stimulation using dentinal barrier as a function of the wavelength is the first step toward establishing the ideal window for biostimulation of pulp tissue previously injured by caries lesion progression and cavity preparation.
