Aims:
The aim of this study was to quantify the debris extruded apically from teeth using rotary and reciprocation instrumentation systems.
Subjects And Methods:
Eighty extracted human mandibular premolars with single canals and similar lengths were instrumented using ProTaper Universal (40, 06; Dentsply Maillefer, Ballaigues, Switzerland), ProTaper Next (40, 06; Dentsply Maillefer, Ballaigues, Switzerland), WaveOne (40, 06; Dentsply Maillefer, Ballaigues, Switzerland), and Reciproc (R40; VDW GmbH, Munich, Germany). Debris extruded during instrumentation was collected into preweighed Eppendorf tubes, which were then stored in an incubator at 70°C for 5 days. The final weight of the Eppendorf tubes with the extruded debris was calculated after obtaining the mean of three consecutive weights obtained for each tube.
Statistical Analysis Used:
Statistical analysis was performed using SPSS version 16.0 software. The groups were compared using the Kruskal-Wallis test for all variables.
Results:
There was no statistically significant difference between the groups (P = 0.1114). However, the ProTaper Universal group produced more extrusion and ProTaper Next produced least debris extrusion among the instrument groups (P > 0.05).
Conclusions:
All instrumentation techniques were associated with extruded debris.
