ABSTRACT

Aim: To analyze instrumentation time in artificial deciduous molars by manual and mechanized technique and to compare the quality of root canal filling using digital radiography. Material and Methods: The sample consisted of 65 teeth, of which 5 were used for calibration of the study (G1), 30 for reciprocating mechanized instrumentation (G2) and 30 for manual instrumentation (G3). The instrumentation time was timed. After the instrumentation, the root canals were obturated in both groups. In order to analyze the quality of the obturation, digital radiographs were used. The D ‘Agostino test was used, and the data presented a non-normal distribution. The Mann-Whitney test was used to evaluate the instrumentation time and the quality of the obturation. The level of significance was set at 5%. Results: Mechanized instrumentation time was faster than manual instrumentation (p ‹0.05), and the degree of obturation quality was more effective in the teeth instrumented by the mechanized technique (p ‹0.05). Conclusion: The mechanized instrumentation technique proved to be more effective in reducing the time and degree of filling of the root canals, and its use provided advantages in the pediatric clinical routine.
