ABSTRACT

Aim: The aim of this study was to compare the diffusion ability of hydroxyl ions through dentinal tubules of different calcium hydroxide-herbal pastes and compare it with the calcium hydroxide paste prepared with saline. Methods: A comparative study regarding the diffusion of hydroxyl ions through dentinal tubules using (1) calcium hydroxide-saline paste (2) calcium hydroxide-tulsi paste (3) calcium hydroxide-ginger paste, conducted on 60 extracted mandibular premolar teeth with a single root canal. After decoronation with a diamond disc and working length determination, the canals were prepared upto 40 k file. Teeth were distributed into three experimental groups and kept in deionised water. Change in pH was evaluated using digital pH meter at 24,72 and 168 hours. Data were analysed by ANOVA test and Post- hoc Tukey’s test using IBM SPSS-20 software. Result: Statistical analysis indicated that group I had the highest pH values at 24 and 72 hours, at 168 hours highest pH values was by group III followed by group II and group I respectively. Group I showed no change in pH values after 72 hours. Conclusion: Herbal preparations allow the maximum ionization of calcium hydroxide and promote sustained release of the ions for a longer duration of time.
