Efficacy of Orange Oil, Lemon Oil and Xylene as Solvents in Removing Gutta Percha from Curved Root Canals: An In-vitro Study

Abstract

Introduction: Root Canal Treatment (RCT) is the most common and effective treatment for saving natural tooth. Despite of modern technology and progress in the materials, failures in endodontic treatment still remains. Microbial infection majorly bacteria in the root canal is the prime cause of reinfection in root canal treatment. Endodontic instruments, solvents, lasers are the different techniques that can be used for removing gutta percha from the root canal. Aim: To compare the efficacy of orange oil, lemon oil, and xylene as solvents in removing gutta percha from curved root canals. Materials and Methods: This in-vitro study conducted in Sharad Pawar Dental College and Hospital, Sawangi Meghe, Wardha, Maharashtra, India, for three months and 24 freshly extracted teeth including incisors, premolars and molars having curved root will be taken. Then, RCT would be performed in all the extracted teeth by using cold lateral compression obturation method. Then all teeth would be divided in three groups (n=8). After one month, the Gutta Percha (GP) would removed by ProTaper Universal system. First group will use orange oil as solvent, second group will use lemon oil as solvent and the third group will use xylene as a solvent. The micro-Computed Tomography (CT) images prior to the application of solvent and after application of solvent will be taken and would be evaluated to check the percentage of filling material remaining. Results: The expected outcome is orange oil and lemon oil to act as a better root canal solvent, as compared to xylene. Conclusion: The determination and comparison of the efficacy of orange oil, lemon oil and xylene as GP solvents from the present planned study will help the clinicians during re-RCT treatment.
