The present study was conducted to compare manual and rotary instrumentation techniques in deciduous teeth. Materials and Methods: The present study was conducted on 120 patients (boys – 60, girls – 60) in the age range of 5–12 years. Patients were divided into two groups of sixty each. Group I patients were treated with rotary files and Group II patients with manual technique. Time taken for instrumentation and obturating the canals in both groups was recorded. The quality of filling was labeled as optimal, underfilled, and overfilled. Results: The mean instrumentation time in Group I was 12.4 min and in Group II was 18.2 min. Chi-square test showed highly statistically significant difference (P < 0.05). The mean filling time in Group I was 1.4 min and in Group II was 2.6 min. In Group I, in 92%, filling was optimal, whereas in Group II, 76% had optimal filling, 5% in Group I and 14% in Group II had overfilling, and 3% in Group I and 10% in Group II had underfilling. Conclusion: In the present study, we found lesser instrumentation time and filling time with rotary system compared to manual endodontic method. ER -
