Instrumentation Time Efficiency of Rotary and Hand Instrumentation Performed on Vital and Necrotic Human Primary Teeth: A Randomized Clinical Trial

Aim: To compare the instrumentation time efficiency of rotary and hand instrumentation performed on necrotic human primary teeth. Methodology: Patients aged 4-7 years were enrolled, forty five teeth (19 maxillary and 26 mandibular teeth), which had a total of 102 canals and completely formed apices and of minimum 10 mm root length were selected. Of the 45 treated primary molars, 31 teeth were diagnosed as having chronic pulpitis, and 14 as having pulp necrosis that responded negative to hot and cold tests; and, clinically, all pulps were confirmed to be necrotic on entrance into the pulp chamber. Results: The mean time spent for rotary root canal preparation and hand preparation for the three groups was GI: 20.10 ± 7.86, GII: 9.37 ± 2.19 minutes and GIII: 10.45 ± 4.77 minutes, respectively. With regard to canal filling quality, 29 cases (64.44%) were flush-filled, 5 cases (11.11%) were under-filled, and 11 cases (24.44%) were over-filled. The Student t test was used to compare data whether there were statistically significant differences between the results obtained clinically. Significance was set at p<0.05. Conclusion: Clinically, time efficacy in primary molar endodontic treatment, especially with the unpredictability and difficulty of canal morphology, is invaluable. The use of rotary files in primary teeth has several advantages when compared with manual K files. *Corresponding author: Jorge Paredes Vieyra, PMB#1513, 710E San Ysidro Blvd. suite “A”, San Ysidro California 92173, USA, Tel: (619) 8463512, 01152664 1230750; E-mail: [email protected] Received March 04, 2014; Accepted March 29, 2014; Published March 31, 2014 Citation: Vieyra JP, Enriquez FJJ (2014) Instrumentation Time Efficiency of Rotary and Hand Instrumentation Performed on Vital and Necrotic Human Primary Teeth: A Randomized Clinical Trial.
