Abstract

Abstract

Aims: The purpose of this study was to evaluate and compare the effect of Triphala and 2% chlorhexidine  and 5.25%hypochlorite sodium on the micro-hardness of root canal dentin used irrigation solutions.

Settings and Design: This experimental study was designed in vitro study

Methods andMaterial: Eighty-eight single-rooted mandibular premolars with single canal were selected. The teeth were sectioned horizontally at mid-root with a diamond disc, then were embedded in resin blocks to facilitate handling. The samples were ground-polished with water-cooled polishing and finishing disks. 88 samples were randomly assigned to four test groups (n=22). Group I: distilled wateras control group; Group II: Triphala; Group III: 2% CHX; Group IV: 5.25% NaOCl. Following treatment with irrigation solutions for 15 minmicro-hardness of dentin blocks was evaluated using Vickers hardness indentation machine. The data were recorded as Vicker’s Hardness number. Statistical analysis used:The results were analyzed statistically by using one-way ANOVA and post hoc-Tukey’s test.

Results: the results indicated that 5.25 % NaOCl solution was significantly decreased root-dentin micro-harness when compared with the control group (p<0.05). Triphala had the least effect on micro-hardness in comparison with  2%CHX and 5.25% NaOCl.

Conclusions: Although there are many factors for irrigation solution preference, according to the results of this study Triphala seems to be an appropriate endodontic solution because of its harmless effect on the micro-hardness of root canal dentin.

Key words: 2% chlorhexidine, dentin micro-hardness, 5.25% hypochlorite sodium,  irrigation, Triphala
