ABSTRACT
Aims:
To compare the apical extrusion of Enterococcus faecalis after instrumentation with three different Ni-Ti rotary instruments- An in vitro study. Settings andDesign:
In vitro study Methods andMaterial:
Forty freshly extracted mandibular premolars were mounted in bacteria collection apparatus and root canals were contaminated with a suspension of Enterococcus faecalis. The contaminated teeth were divided into 4 groups of 10 teeth each according to rotary system used for instrumentation Group1 Hyflex files, Group 2 GTX files, Group 3 Protaper files and Group 4 control group (no instrumentation). Bacteria extruded after preparations were collected into vials and microbiological samples were incubated in BHI broth for 24 hrs. The colony forming units were determined for each sample. Statistical Analysis Used Statistical analysis was done using one way ANOVA followed by post hoc independent “t” test.Results:
GTX files extruded least amount of bacteria followed by Hyflex files. Maximum extrusion of E. faecalis was seen in rotary Protaper group.Conclusion:
Least amount of extrusion was seen with GTX files followed by Hyflex files and then rotary Protaper system.
