In vitro evaluation of antimicrobial activity of different Gutta-percha points and calcium hydroxide pastes.

Purpose: To evaluate the antimicrobial activity of different compositions of Gutta-percha points and calcium hydroxide (Ca(OH)2) pastes, used in endodontic therapy.

Materials And Methods: The evaluated material consisted of Gutta-percha points containing Ca(OH)2, Gutta-percha points containing chlorhexidine (Chx), conventional Gutta-percha points and Ca(OH)2 pastes. Antimicrobial properties of Chx and CaOH paste are compared with CaOH points.

Unilateral molariform macrodont mandibular second premolar: an unusual case report in a nonsyndromic patient.

Macrodontia is a rare dental anomaly that refers to teeth appears larger than normal. It can be generalized or isolated macrodontia. Isolated macrodontia involving premolar is very rare.

Evaluation of Different Disinfactants on Dimensional Accuracy and Surface Quality of Type IV Gypsum Casts Retrieved from Elastomeric Impression Materials.

Background: The present study was done to evaluate the dimensional stability and surface quality of Type IV gypsum casts retrieved from disinfected elastomeric impression materials.

Materials And Methods: In an in vitro study contaminated impression material with known bacterial species was disinfected with disinfectants followed by culturing the swab sample to assess reduction in level of bacterial colony. Changes in surface detail reproduction of impression were assessed fallowing disinfection.
