Abstract This study designed to evaluate the effect of sodium hypochlorite, MTAD, and Tea Tree Oil irrigation solutions on bacteria in infected root canals with periapical lesions, and their effect on healing of periapical lesions. The study conducted as follows: Part I: total of thirty patients-males and females-were included in this study, their ages ranged between 20-55 years. Each of them was diagnosed for being healthy, not suffering from any systemic illness, having a radiographically evident periapical radiolucency related to either mandibular or maxillary single rooted teeth. Standardized intraoral periapical radiographs were taken at the baseline using bite blocks with a long-cone paralleling technique. Before biomechanical preparation, root canals were irrigated using sterile saline prior to sampling. They were then sampled using three paper points per each sample S1. The paper points were placed into transport medium of thioglicolate broth and carried in pre-sterilized screw tubes for microbial culturing. |
