Filter by:The aim of this randomized, controlled, prospective clinical trial is to evaluate the performances of a universal adhesive in three different application modes, a self-etch adhesive and an etch&rinse adhesive in restoration of non-caries cervical lesions. Thirty-four patients will receive restorations. Lesions will be divided into 5 groups according to adhesive systems and application modes: CU-SE: Clearfil Universal Bond Quick in self-etch mode, CU-SLE: Clearfil Universal Bond Quick in selective etch mode, CU-ER: Clearfil Universal Bond Quick in etch&rinse mode, CSE: Clearfil SE Bond, TB: Tetric N-Bond. Restorations (Tetric N-Ceram composite) will be scored with regard to retention, marginal discoloration, marginal adaptation, recurrent caries and post operative sensitivity using modified USPHS criteria after 48 months. Two examiners who is not involved in the placement of restorations will conduct the evaluations. Descriptive statistics will be performed using Chi-square tests.
Suitability of intraoral impressions for assessment of wear of teeth and restorative materials over 60 months, using the gypsum replica method and 3-D laser scanning: perspective clinical and laboratory evaluation.
LAVA Ultimate composite restorations will be used as restorative material to reconstruct severely worn dentitions.
A randomized, controlled clinical trial is designed to analyze the wear of enamel by opposing polished monolithic zirconia crowns and by the polished veneer surfaces of metal-ceramic crowns. This single-blind pilot study will involve a total of 30 teeth that require full coverage crowns that oppose natural antagonist teeth. The objectives of this research are to test the following hypotheses: (1) differences between mean wear of antagonist enamel by polished monolithic zirconia crowns and by the polished veneer surface of metal-ceramic crowns are statistically significant; (2) differences between mean wear of antagonist enamel by opposing polished monolithic zirconia crowns and enamel by opposing enamel are statistically significant; and (3) differences between mean antagonist wear of enamel by opposing polished veneer surfaces of metal-ceramic crowns and enamel by opposing enamel are statistically significant.
