Abstract

The purpose of this study was to measure hydroxyl ion diffusion through dentinal tubules. Eighty single-rooted teeth were instrumented and divided into 8 groups. Groups 1 and 3 were irrigated with 10 mL saline and 10 mL sodium hypochlorite (NaOCl), respectively. Groups 5 and 7 were irrigated with 3 mL and 1 mL of 17% ethylenediaminetetraacetic acid (EDTA) and 10 mL NaOCl, respectively. Groups 2, 4, 6 and 8 were irrigated as in groups 1, 3, 5 and 7, but calcium hydroxide was placed in the root canals. The pH was recorded for 30 days, a defect was made in the cementum, and the pH recorded for an additional 30 days. The greatest rise in post-defect pH was for group 6, which was significantly greater (p < 0.01) than all other groups. A final irrigation with 3 mL EDTA and 10 mL NaOCl allowed greater hydroxyl ion diffusion.
