Evaluation of Remineralization Seen in Dentin Related to Ceramic Restorations.

Background: Recently, the caries management had shifted from extension for prevention to early detection and remineralization of remaining tooth structure using noninvasive techniques.

Aim: The present trial was carried out to assess the effect of adding mono-n-Dodecyl phosphate as a surfactant to ceramic on remineralization of dentin.

Materials And Methods: The 32 teeth were divided into the following four groups randomly ( = 8 each group) - Group I: cavities not restored, Group II: Restored with ceramic, Group III: restored with ceramic and 2% mono-n-Dodecyl phosphate, and Group IV: restored with ceramic and 5% mono-n-Dodecyl phosphate.

Comparative evaluation of flexural fracture resistance of mandibular premolars after instrumentation with four different endodontic file systems: An study.

Background: Under axial loading, there is stress concentration around the cervical areas especially in the premolars because of their location in the arch.

Aim: To evaluate and compare flexural fracture resistance of mandibular premolars after instrumentation with ProTaperUniversal, ProTaper Next, OneShape, and WaveOne endodontic file systems.

Methods: Seventy-five mandibular premolar teeth with single straight canals were divided into five different groups (n = 15): Group A: Control, Group B: ProTaper Universal (PTU), Group C: ProTaper Next (PTN), Group D: OneShape, Group E: WaveOne.
