Background: One of the factors that most negatively affect the endodontic instrumentation process in primary teeth are the presence of extruded debris in the periapical region. Therefore, different techniques have been evaluated to reach an answer to the question regarding which root canal preparation method produces the least amount of debris extrusion. Objectives: The main objective of this study was to assess the amount of debris extrusion as well as irrigation associated with 3 different instrumentation techniques: a rotary system (PROTAPER NEXT – PTN),a new reciprocating system (S-ONE pro – SO) and hand K-files. Material and methods: Forty-eight primary mandibular molars with a single distal canal were selected and randomly divided into 3 groups (n = 16). Three different techniques were used for the canal instrumentation of each group, comprising PTN, WO and hand K-files. Pre-weighed Eppendorf tubes were usedfor the collection of debris extrusion, then stored in an incubator at 70°C for 5 days. A one-way analysisof variance (ANOVA) test was used for data analysis, followed by Tukey’s post hoc test. Results: Statistically significant differences were found while comparing the PTN and SO systems with the hand files. Both PTN and SO showed less debris extrusion toward the periapical tissues than the hand files. Still, no statistically significant differences were seen between the PTN and SO groups. Conclusions: Generally, debris extrusion occurred in all of the 3 experimental groups. The PTN and SOsystems showed the least debris extrusion as compared to the hand files during the root canal instrumentation of the primary teeth, and for these reasons along with the shorter operating time, it may be concluded that using rotary and reciprocating systems rather than manual files is highly advisable. However, a clinical assessment is suggested.
