Non-Surgical Management of Non-vital Teeth with Periapical Pathosis by Conventional Root Canal Treatment: A Clinical and Radiological Evaluation

Abstract

Background: Infections of the dental pulp occur as consequence of caries, operative dental procedures and trauma, and involve a mixed, predominantly Gram-negative, anaerobic bacterial flora. Objectives: The study was done to evaluate the success rate of non-surgical management of non-vital teeth with periapical pathosis. Methods: A total number of 40 infected teeth with periapical lesion were treated by Conventional Root Canal Treatment. Irritants from the root canal system was removed by mechanical instrumentation (Crown down Technique), chemical irrigation with NaOCL and by using Calcium Hydroxide as intracanal medicaments and fluid tight obturation both apically and coronally resulting repairs of inflamed periradicular tissues. Depending on the extension of tissue damage repair varies from a simple reduction and resolution of the inflammation to a more complex regeneration involving remodeling of bone, periodontal membrane and cementum. Results: This study present 2 years clinical and radiological follows up period. Among 40 cases 32 cases could be treated as acceptable as their responses were good both clinically and radiologically and 5 patients came back with some complications among them 3 cases were uncertain and 2 cases were unacceptable. Conclusion: This study suggests that Conventional root canal Treatment is an effective procedure for saving teeth with periapical pathosis.
