OBJECTIVE The purpose of this study was to evaluate the distribution of microorganisms in the root canal system (RCS) and periapical lesions of dogs' teeth after rotary instrumentation and placement of different calcium hydroxide [Ca(OH)2]-based intracanal dressings. MATERIALS AND METHODS Chronic periapical lesions were experimentally induced in 80 premolar roots of four dogs. Instrumentation...
The major goal of root canal treatment is to remove irritants from the root canal system, to obturate the cleaned and shaped root canals, and to prevent recontamination. Ray and Trope proposed that coronal microleakage may be a major cause of endodontic failure. Many previous studies have examined that coronal leakage might occur, even in well obturated root canals. One of the most important co...
The aim of this study was to evaluate in vitro antimicrobial activity of 4 antibiotic agents (for E.faecalis) and 4 antifungal agents (for C.albicans) by agar dilution method. Additionally, modified strip diffusion method was used for detection of in vitro antimicrobial activities of 5% NaOCl, 2.5% NaOCl, 17% EDTA and 2% CHX and agar diffusion method for detection of in vitro susceptibilities o...
