A Comparative study for the management of Peri-radicular Pathosis by Conventional Root Canal Therapy and Non Instrumental Endodontic Therapy.

Non-surgical endodontics is one of the realities in modern endodontics globally which is a highly sophisticated specialized technical clinical procedure to conserve the teeth. Lesion Sterilized Tissue Repair (LSTR) is an alternative of conventional non-surgical endodontics (C-RCT) considered being a valuable adjunct to the treatment of infected root canal. This cross sectional prospective study was carried out in the department of Conservative Dentistry & Endodontics, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from January 2002 to January 2003. This study involved 100 cases of symptomatic endodontically involved teeth with peri radicular pathosis treated by non-surgical method (C-RCT) & (LSTR therapy) in multi-visit technique and immediate and long-term clinical and radiological follow-up done for 24 months. The result revealed complete disappearance of sinus tract 46(92%) in C-RCT and 35(70%) in LSTR therapy group and success in C-RCT was 88% and in LSTR therapy as 86% after 24 months follow-up by clinical and radiological evaluation. So, it can be concluded that non-surgical approach in the management of periradicular pathosis by C-RCT and LSTR therapy was found safe, effective and practical method of treatment of an endodontically involved tooth.
