Effect of potential remineralizing agent and antioxidants on color stability of bleached tooth exposed to different staining solutions.

Aim: The aim of the study was to evaluate the effect of staining solutions, remineralizing agent, and antioxidant on color stability of tooth during and after bleaching.

Materials And Methods: Ninety human central incisors were bleached using 35% hydrogen peroxide (Pola office) and allocated to three groups ( = 30). Group I stained with cola-based soft drinks, Group II stained with pomegranate juice, and Group III stained with turmeric.

To evaluate and compare the effect of different light-curing modes and different liners on cuspal deflection in premolar teeth restored with bulk filled or incrementally filled composite measured at different time intervals.

Aim: The aim of this study is to evaluate and to compare the effect of different light-curing modes and different liners on cuspal deflection in premolar teeth restored with bulk filled or incrementally filled composite measured at different time intervals.

Materials And Methods: The study was divided into two parts (Part 1-different curing modes, Part 2-different liner) each with sixty extracted human upper premolar teeth with standardized large mesio-occlusal-distal cavities prepared. Each part was divided into two groups according to the composite used (Group A-Filtek Z350 XT, Group B-Sonic fill).
