BackgroundSeveral hand instruments and rotary systems have been evaluated for success and failure of single visit root canal treatment. Moreover; studies focusing on the comparison of the effectiveness of rotary systems versus hand instrumentation have yielded mixed results in the terms of clinical and radiographic success of single visit root canal treatment. However; most dentist they reserve single visit root canal treatment for vital pulp. Therefore; in this study we have evaluated the success rate of single visit root canal treatment on teeth with non-vital pulp. Aim: The aim of study was to determine the clinical and radiographic success rate of single visit root canal treatment performed on non-vital tooth along with periapical radiolucency ranging from 0-2 mm in diameter by hand and rotary protapers. Methods & material: 40 single rooted non-vital teeth with single root canal from the patients in the age range of 30-40 years were selected for the study. Single visit endodontic treatment was done in all the teeth with hand & rotary protaper. Two groups were made with 20 patients each. Group A treatment was done with hand protaper and group B with rotary protaper. Zinc oxide eugenol sealer and Lateral condensation technique was used to obturate the canals. All the patients were given the recall at 6 and 12 month interval, to decide the clinical and radiographic success of treatment done. Result: Both hand & rotary protaper group showed 100% success rate at 6 month recall, there was no statistically significant difference (p>0.05) of success rate in the two groups at 6 month recall. At 12 month recall hand protaper group showed 100% success rate, while rotary protaper group showed a success rate of 85%. The difference of success rate at 12 month in the two group was not statistically significant (p>0.05). Chi-square test and Kruskal Wallis test were used for statistical analysis. Conclusion: One visit endodontics can be performed on teeth with necrotic pulp and/or associated with small periapical lesions with hand and rotary protaper.
