Abstract

Aim

To evaluate the volume of sodium hypochlorite extruded from the apex on using various mechanical activators.

Materials and methods

Forty extracted single-rooted mandibular premolar teeth were taken. Standardized access opening with chemicomechanical preparation till protaper F3 was done with 2 mL of 5.25% sodium hypochlorite in between instrumentation of each file. The apical patency was checked with 10 K file. The teeth were then divided into four groups: Group I (n = 10) activation was done with #20 side-vented needle; group II (n = 10) activation was done with GP cones; group III (n = 10) activation was done with Irrisafe tips; group IV (n = 10) activation was done with endoactivator. As much as 10 mL of 5.25% sodium hypochlorite has been used with each group to activate the irrigant. The extruded sodium hypochlorite during activation with various systems was been collected in prepared apparatus. The obtained samples were analyzed for sodium ion concentration. Evaluation of the volume of sodium hypochlorite extruded from the apex was analyzed using absorption spectrometry. Then the above results were then statistically analyzed.

Results

Varying amount of apical extrusion was seen among the above study groups. Minimum amount of apical extrusion was seen with endoactivator. Maximum amount of apical extrusion was seen with needle irrigation followed by GP cones.
