The primary outcomes for this study were the Schiff sensitivity scores for air, cold, and acidic stimuli and VAS scores at baseline (0) and at 2 and 4 weeks. For each test group, the Schiff sensitivity score for each stimulus modality was calculated for each patient and tooth at each assessment. Descriptive statistics were computed for each measurement and the experimental group. The differences in Schiff sensitivity scores between the follow-up and experimental groups were evaluated using a linear mixed-effects model. Statistical significance was set at
