Dental changes have been reported to the teeth of uremic patients that consequently affect bonding of that tissue to fixed restorations.

This study demonstrated that the incorporation of nanoparticles does not improve the surface properties of the ionomeric cements when exposed to simulated dietary solutions. However, the nanofilled composite resin was more resistant to chemical degradation.

The use of different surface treatments (airborne particle abradion or tribochemical silica coating/silane coupling system) on zirconia ceramic for different adhesive resin cements (dual or self-cure) may improve bond strength between resin cements and zirconia ceramic.

Reinforcement of teeth with coronal fractures and immature weakened roots with resin composite that was cured by the modified layering technique could be a promising approach for practitioners.

Forty seconds of light exposure in increments up to 3 mm of a novel silorane-based composite resin produced higher degree of conversion and hardness than thicker increments, using halogen or LED units.


This article discusses indications and limitations of enamel microabrasion treatment and indicates that this technique may be a promising alternative to restoring severe stains.


The active application mode seems to be an easy and effective clinical alternative to improve the retention rates and reduce marginal staining of one-step self-etch adhesives in noncarious cervical lesions.

Tooth sensitivity is the most frequent adverse effect of in-office vital tooth whitening. The use of a desensitizing gel after tooth whitening may reduce the incidence and severity of in-office vital tooth-whitening sensitivity.

Except for the better marginal adaptation that packable resin composite showed, silorane-based restorative, nanofilled resin, and packable resin composite resulted in similar clinical performance in restoring Class I cavities after 3 years.


The sandwich technique results in more microleakage than classically bonded composite resin restorations.

This study showed that silorane-based composites demonstrated acceptable performance in all parameters studied (water sorption, solubility, and roughness), supporting their use as an alternative restorative material.

Pulsed Nd:YAG laser may contribute to the tensile bond strength of resin to enamel and increase the acid resistance of enamel surfaces. It can be a clinical alternative for pretreating enamel surfaces when direct bonding orthodontic attachments or adhesive restorations.

Benzalkonium chloride preserves resin-dentin bonds by reducing collagen solubilization. When incorporated into adhesive blends, benzalkonium chloride provides comparable bond stability to other inhibitors and application protocols without adding more steps to the bonding sequence.

The application of the low-fusing glaze porcelain followed by hydrofluoric acid etching and silanization and tribochemical silicatization generates strong bonds between resin cement and zirconia. Panavia generates stronger bonds than does Clearfil.

The use of resin-modified glass ionomer cement as an intermediary base provides lower microleakage, indicating better sealing of the tooth-restoration interface.

The findings in the present study suggest that in-office digital impressions and subsequent computer-aided design/computer-aided manufacturing (CAD/CAM) fabrication of ceramic crowns could result in marginal and internal fit similar to that of hot-pressed all-ceramic crowns.

The shade guide must remain consistent in the shade-matching process. If there is a perceptible color change in the shade guide, the result will be inconsistent shade determination and, thus, an unacceptable restoration.

The use of RMGIC liner with composite resin restorations reduces microleakage. The silorane-based composite showed lower volumetric polymerization shrinkage than methacrylate-based composites.
