In vitro comparison of the marginal adaptation of cold ceramic sealer with the single-cone obturation technique versus AH-26 sealer with the lateral compaction technique in single-canal teeth.

Objectives: This study aimed to compare the marginal adaptation of a cold ceramic (CC) sealer with the single-cone obturation technique with that of an AH-26 sealer with the lateral compaction technique in single-canal teeth.

Materials And Methods: In this in vitro experimental study, the root canals of 24 extracted single-rooted single-canal teeth were instrumented to F3 files by the crown-down technique and randomly assigned to 2 groups (n = 12). The root canals were obturated with a CC sealer and single-cone obturation technique with 4% gutta-percha in group 1 and with an AH-26 sealer and lateral compaction technique with 2% gutta-percha in group 2.

Antimicrobial efficacy of antiplaque agents of common toothpastes against and : An study.

Background: This study was designed to evaluate the antimicrobial activity of common gum protection and antiplaque toothpastes against () and () as important periodontal pathogens.

Materials And Methods: This experimental study investigated the antimicrobial activity of 15 commonly used toothpastes from different companies on the two common types of periopathogens, and . The antimicrobial activity of toothpaste was evaluated at three concentrations of 100%, 50%, and 25% and analyzed by agar well diffusion plate method and zone of inhibition.
