The aim of this study was to compare the removal potency of calcium hydroxide [Ca(OH)2], triple antibiotic paste (TAP) and doxypaste using manual irrigation with sodium hypochlorite (NaOCl). This was an in vitro experimental study conducted at DIDC and DRIBBS, Dow University of Health Sciences and Department of Material Sciences, NED University of Engineering and Technology in December 2015. Thirty extracted single and multirooted teeth having 45 canals were prepared using k files upto master apical file (MAF). The canals were divided into 3 groups (15 canals in each group) receiving Ca(OH)2, triple antibiotic paste and doxypaste respectively. After storing in an incubator for 15 days these medicaments were removed by manual filing followed by irrigation with side vented needle at 1mm from working length using sodium hypochlorite and the sample observed under a stereomicroscope after sectioning. Statistical analysis was performed using SPSS 16.0 to determine the significance of the result by applying kruskal-Wallis test (P-value 0.05).

Remnants of medicaments were found in all three of the experimental groups with calcium hydroxide being associated with highest amount of residues (33.3%) which was more than 2 times greater than triple antibiotic paste (11.6%) and 6 times greater than doxypaste (5.72%). This show that failure in completely removing these medicaments from the canal walls may adversely effect the endodontic treatment outcome by compromising the efficacy of the sealer.
