Background and Objective: The extrusion of debris beyond the root apex is regarded as the main cause of pain following root canal treatment and the amount of extruded debris is closely related to the technique and extent of canal cleaning and shaping. The aim of this study was comparison of apical debris extrusion during root canal preparation in primary molars using conventional and reciprocal systems.
Methods: This experimental study was performed on 32 primary mandibular second molar teeth (16 in conventional rotary group and 16 in reciprocal group). The distal root of teeth were prepared to working length in two groups. The extruded debris were collected in the Falcon 15ml tubes. Then the tubes were placed in an incubator for 5 days due to the presence of irrigation solution extruded from the Apex. After that, the tubes were placed on the scale with an accuracy of 0.0001g and the tubes weight were measured again. The amount of extruded debris was obtained from the difference of two weighing numbers for each tube. At the end, the data were analyzed by SPSS software version 26.
Findings: The mean weight of debris in conventional and reciprocal groups were 0.0115g±0.0201 and 0.0122g±0.0051 respectively. The mean rank of conventional and reciprocal groups were 11.69 and 21.31 respectively. In reciprocal group, the level of apical debris extrusion was significantly higher. (p=0.003).
Conclusion: Due to this study, reciprocal engine-driven filing extrudes more apical debris than conventional engine-driven filing. |
