N2 - Introduction: This study aimed to evaluate the impact of pH on the dentin piezoelectric response in root canal treated teeth. Materials and Methods: Thirty extracted mandibular canines were selected by simple random sampling and based on specific inclusion criteria. The middle third of each root was cut into cubic specimens of approximately 2 mm × 2 mm x 4 mm. The prepared samples were soaked in 17% EDTA and 1% sodium hypochlorite for 1 minute. The sections were rinsed in distilled water, dried immediately, and then randomly allocated into 3 groups of 10 each. Samples in each group were soaked in one of 3 solutions with pH 4.4, 7.4, or 10.4 for 5 min. A compression load was applied by a universal mechanical testing machine. The 8000-8-SM scanner detected the potential generated. Results: No significant differences were observed among the groups when the force was applied vertical to the dentinal tubules (P > .05). However, all subgroups indicated significant differences when the force was applied along the dentinal tubules (P < .05). When the force was applied along to the tubules, the mean dentin piezoelectricity was higher in the alkaline, neutral, and acidic groups, respectively. Conclusion: This study demonstrated that the piezoelectric properties of dentin in root canal treated teeth can be influenced by variations in pH, depending on the direction of force applied to the dentinal tubules.
