Comparative Evaluation Of Gutta- Percha Solvents in Endodontic Retreatment – An InVitro Analysis
Main Article Content
Abstract
Introduction
The epidemiological surveys conducted so far have reported that more number of root canal treated teeth are associated with periapical radiolucencies as a result of poor endodontic therapy. The aim of this study was to evaluate the efficacy of gutta percha removal in endodontic retreatment using orange oil and comparing it with current gold standard Xylene.
Materials and Methods
Freshly extracted 30 single rooted teeth were used in this study. It was divided into two groups by alternate sampling technique.
The teeth were prepared using rotary protaper universal system and obturated by single cone technique. Two drops of solvents were placed in the canal orifice of obturated root canal and gutta percha(GP) was removed using peso reamer and manual filing with H-files. Post Operative radiographs were taken to visualize the efficacy of gutta percha removal using different solvents.
Results
The remaining amount of GP present after using GP solvents are evaluated using Hulsman and Slotz classification(Hülsmann & Stotz, 1997). Radiographic and histological studies were done to evaluate the effectiveness of GP solvent. Statistical analysis was done using the Chi-Square test.
