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 conï¬Ârmed 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 signiï¬Âcant differences between the results obtained clinically. Signiï¬Âcance 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.
