Abstract

  As a consequence of root canal preparation, dentinal chips, irrigants and pulp remnants are extruded into preradicular space. This phenomenon may lead to post endodontic flare-ups.

The Objective: Of this study was to compare the amount of extruded debris with three endodontic NiTi enginedriven systems.

Material and Methods: A total number of 63 freshly extracted human molars were selected. Teeth were divided randomly into three equal groups (21 teeth each group) according to type of Ni-Ti rotary file system; (A) Protaper Next, (B) Hyflex CM and (C) Neolix. Standard Access cavity prepared and checked for patency using K file #10 and #15. Root canal instrumentation on mesial root canals done. Root canal instrumentation on mesial root canals done. Debris were collected after mesial root instrumentation in pre-weighed eppendorf tubes. The eppendorf tubes were weighed 2 times on the analytical balance: First weight: Before instrumentation. Second weight: After evaporation of moisture and irrigant and incubation.

Results: Neolix rotary system showed least amount of extruded debris while Hyflex CM rotary system showed highest amount of extruded debris.

Conclusion: All endodontic rotary instruments tested produced apical extrusion of debris.
