Aim: To compare smear layer removal ability and evaluation of compressive strength of root dentin using various concentrations of garlic extract and 17% EDTA solutions.
Materials and Methodology: One hundred and twenty human mandibular first premolars were decoronated to a root length of 17mm. They were cleaned and shaped upto 40k size file using saline as an irrigant throughout the instrumentation. The specimens were equally divided into 4 groups according to final irrigant used for both smear layer and compressive strength evaluation; group 1- 17% EDTA, group 2 – 30mg/ml garlic solution, group 3 – 10mg/ml garlic solution, group 4 – saline. Samples were split longitudinally and examined under microscope for smear layer evaluation at coronal, middle and apical levels. For compressive strength evaluation, specimens were cut to obtain 6mm cylinders and placed under universal testing machine at a cross head speed of 1mm/min.
Results: 17% EDTA had a lowest mean range of smear layer scores compared to other groups. Coronal sections recorded lowest mean rank of smear layer scores when compared to apical region scores. Compressive strength values were lowest for EDTA group.
