Non-Vital Teeth Management with Periapical lesion by Conventional Root Canal Treatment – A Clinical and Radiological Evaluation

Background: Dental pulp infections are a result of caries, dental procedures and trauma, and consist of a mixed, predominantly Gram-negative, anaerobic bacterial flora. Objectives: The study was performed to check the rate of success of non-surgical management of non-vital teeth with periapicalpathosis. Methods:40 infected teeth having a periapical lesion were treated by Conventional Root Canal Treatment. The irritants from the root canal system were removed using mechanical instrumentation (Crown down Technique), chemical irrigation with NaOCL and by Calcium Hydroxide as intracanal medicament. Also, fluid tight obturation both apically and coronally was done which resulted in repairs of inflamed periradicular tissues. Depending on the extension of damage of tissue, 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 presents 2 years clinical and radiological follow up period. Out of 40 cases, 32 cases could be considered as acceptable as their responses were good both clinically and radiologically. 5 patients came back with some complications out of which 3 cases were uncertain and 2 cases were unacceptable. Conclusion: It can be seen that Conventional root canal Treatment is a very effective procedure for saving teeth with periapicalpathosis
