- Abstract
Objectives: The aims of this in vitro study were to compare the efficiency of 5.25% sodium hypochlorite (NaOCl) in conjunction with 17% ethylene diamine tetra acetic acid (EDTA) and EDTA with tension-active agent (SmearClear®) for the removal of calcium hydroxide (Ca(OH)2) from root canals and to determine the root canal wall cleanliness at the coronal, middle and apical third regions. Materials and Methods: The root canals of 28 freshly extracted mandibular second premolars were prepared with ProTaper, after the placement of (Ca(OH)2) into the canals, two irrigation solutions were used for its removal. In Gr 1, 5.25% NaOCl with SmearClear® was used while in G 2 5.25% NaOCl with 17% EDTA was used. Four teeth were used as positive and negative controls of two teeth each. After longitudinal sectioning; the dentinal walls were examined using scanning electron microscope. Statistical analysis was carried out using the Kruskal-Wallis and Mann-Whitney tests. Results: Significantly less residual material was obtained with NaOCl-17% EDTA at the apical third region compared to SmearClear irrigation solution (P = 0.029). Whereas no significant difference between the two solutions at the coronal (P = 0.343) and middle (P = 0.686) third regions. Conclusions: Within the limitations of this study, both tested EDTA irrigation solutions with or without tensioactive agent produced effective root canal cleanliness at the coronal and middle third regions. However, 17% EDTA was superior in removing the (Ca(OH)2) dressing at the apical third region compared to SmearClear irrigation solution.
