Abstract
The aim of this study is to investigate the effect of different access cavity designs and irrigation solutions on the removal of CaOH 2 from root canals. A total of 84 human mandibular molars were selected for this study. The samples were divided into three main groups of 28 teeth to be prepared: TAC, UCAC and TrAC. CaOH 2 was placed into the root canals of the teeth after cavity preparation and root canal shaping. To allow imaging under the CLSM, CaOH 2 was mixed with rhodamine B dye. The samples were then divided into 4 subgroups according to the irrigation solutions (saline, 17% EDTA, 70% ethanol, 0.2% chitosan) used to remove CaOH 2 . After the removal process, apical 3 mm sections were taken, and images of these sections were obtained using a CLSM. The images were analyzed with ImageJ software. The obtained data were analyzed using two-way anova and tukey post hoc tests, keeping the significance level at p<0.05. The TrAC group showed statistically significantly cleaner canal walls compared to the UCAC group(p0.05). Also, no significant difference was observed between 0.2% chitosan and 17% EDTA (p>0.05). It was observed that 70% ethanol removed CaOH 2 from the canal walls at a statistically significant level compared to 17% EDTA (p<0.05). Cavity designs were found to influence the amount of calcium hydroxide removed from root canals. Furthermore, 70% ethanol and 0.2% chitosan may serve as potential alternatives to 17% EDTA for the removal of calcium hydroxide.
