Comparision of apically extruded debris during retreatment procedure by two types of endodontic instruments

Abstract :

 Background: During root canal treatment, canal deis during shaping and cleaning inadvertently is extruded through the apex. This happens not only during the routine endodontic cases but also during the retreatment cases. Objective: This study analyzed in–vitro the amount of deis extruded through the foramen using two instrumentation techniques during endodontic retreatment. Material and methods: Sixty roots of mandibular first premolars were selected, instrumented with anatomical diameter up to size number 40 ISO file and then obturated with gutta–percha and zinc–oxide eugenol sealer by lateral condensation. They were then divided into two groups of 30 each. The first group was instrumented with ISO K–files for gutta–percha removal and the second group was instrumented with Protaper retreatment files and gutta–percha was removed. All teeth were irrigated with distilled water. The deis extruded through the foramen were collected and weighed by an analytical balance. Results: Group 2 had the lowest average for material extrusion through the foramen followed by group 1. When Tukey test for statistical analysis was applied, significant difference among groups were found (p = 0.02). Conclusion: It can be concluded that Protaper retreatment files produce significantly less deis as compared to K–files.
