Aim: To analyze the effect of RcPrep, phytic acid, and etidronate on dentinal defect formation during root canal preparation, a scanning electron microscopic study.
Materials and Methods: Twenty samples of extracted single-rooted mandibular premolar teeth were decoronated at cementoenamel junction. Samples were grouped into 5 groups, Control Group (5%sodium hypochlorite and distilled water), GROUP A(5%sodium hypochlorite and 1% phytic acid), GROUP B (5%sodium hypochlorite and etidronate), Group C (5%sodium hypochlorite and RcPrep). Biomechanical preparation of all the samples was done using Dentsply Protaper files (S1, S2, F1, F2, F3) with irrigation using respective irrigants mentioned in the respective groups.
All the specimens were subjected for scanning electron microscopy for detection dentinal defect formation in each group.
Result: Irrigation with 5% NaOCl + 1% Phytic acid caused the maximum dentinal defect formation in root dentin while Irrigation with 5% NaOCl + Distilled water caused minimum dentinal defect formation.
