Evaluation of a standard shade guide for color change after disinfection.

Objective: To determine if surface disinfectants cause a change in the shade perception of a standard Classic Vitapan shade guide.

Method And Materials: Consistency in shade selection for dental restorations involves many factors, and one of the most important is the shade tabs used in the selection process. Ten shade tabs each of shades B2, D2, C1, and A3.

Performance of 2 packable composites at 12 months.

Objective: The purpose of this randomized, double-blind, clinical trial was to compare the marginal seal of 2 packable resin composite materials in moderate to large lesions on molars.

Method And Materials: Fifty participants in need of a moderate to large Class 2 or complex Class 1 molar restoration were randomly distributed into 4 groups, to receive either Alert (Jeneric/Pentron) or SureFil (Dentsply/Caulk) resin composite with or without a surface sealer. Each participant received one restoration.

Predictors of non-carious loss of cervical tooth tissues.

This Predictor Variables study is designed to determine which one of 11 factors evaluated may be correlated to Non-carious Loss of Cervical Tooth Tissues (NLCTT) using subjects with and without NLCTT. The ultimate objective is to successfully predict the path toward risky behaviors and reduce the incidence of NLCTT.

Depths of cure and effect of shade using pulse-delay and continuous exposure photo-curing techniques.

This study investigated the extent of cure (monomer conversion into polymer) of a variety of photo-initiated resin composites and different shades. Cure values were measured at the top surface and at simulated lighting conditions 0.5, 1.
