Aim: This study aimed to compare smear layer removal ability of different solutions of Triphala (TA) when used in specific irrigant protocols in curved canals. Materials and Methods: Seventy-four mandibular first molars with 25-35 degrees of curvature of mesial roots were selected and standardized, and canals were prepared. As the initial rinse solution (8 mL), 5% sodium hypochlorite was used. Samples were divided into control (Group I--normal saline, Group II--17% ethylenediaminetetraacetic acid) and experimental (Group III, IV, V, VI, VII, VIII, and IX) groups based on the type of final rinse solution (5 mL) used, that is, TA-premixed (P), TA-(P)-sonic, TA-(P)-ultrasonic, 3% TA solution, 5% TA solution, 10% TA solution, and 10% citric acid. Samples were dehydrated, split buccolingually, splutter coated, and examined in field emission scanning electron microscope. Results: Among the experimental groups, Group V presented the least amounts of smear and debris in all thirds of the root canal with mean values of 1.6 ± 0.63 and 1.6 ± 0.62, respectively, and on comparison with Group II the results were comparable, and no significant difference was found statistically (P > 0.05). Group V presented with the highest amount of erosion with loss of peritubular and intertubular dentin at all levels with mean values of 1.60 ± 0.51. Conclusion: The use of TA as a final rinse solution during biomechanical preparation seems promising. [ABSTRACT FROM AUTHOR] |
