ABSTRACT Objective: The purpose of this study was to quantify the amount calcium ions removed from root canal by etidronic acid (HEBP), BioPure MTAD, and SmearClear using atomic absorption spectrophotometer. Materials Methods: Fifty (n = 50) freshly extracted human mandibular premolar teeth were collected decoronated at cementoenamel junction. canals prepared in a crown down fashion rotary system copiously irrigated with 1.0% sodium hypochlorite. All specimens rinsed deionized water. Based on type chelating agent used, samples 10) randomly divided into five (four test one negative control) groups. Accordingly, Group I - 9% HEBP, II 18% III SmearClear, IV V normal Saline. Subsequent irrigation, solution tube subjected spectrophotometer for quantification canal. Results: mean concentration (mean ± standard deviation) all groups (I–V) 13.32 0.54 μg/ml, 16.36 0.27 20.04 0.24 18.15 0.39 8.74 0.49 respectively. Conclusions: most effective removal Hence, its combined use an organic solvent can be recommended efficient smear layer removal.
