Purpose: The aim of this study was to evaluate dentin sensitivity and clinical effects following removal of cervical enamel projections from human teeth using three rotating instruments. Matherials and Methods: In this study, 15 of 20 total molar teeth with furcation lesions were classified using the instruments, and each group contained five sites. Each site was treated with periodontal flap surgery, and cervicial enamel projections were removed using a piezoelectric ultrasonic scaler, periodontal bur, and diamond bur. Five sites without cervical enamel projections set the control group. Patients’ dentin sensitivity to compressed air was examined based on a visual analogue scale before and 1, 4, 8, 12 weeks after periodontal flap surgery. Probing depth, gingival recession, and attachment level were evaluated at 12 weeks after surgery. Results: In all groups, probing depth reduction and attachment gain were significantly detected at 12 weeks after surgery (p<0.05), and there was no significant difference in cervical enamel projection removal methods (p>0.05). Attachment gain was greater in the periodontal bur group compared to the group without cervical enamel projections (p<0.05). In all groups, there was no significant difference in patients’ dentin sensitivity to compressed air at all until 12 weeks after surgery (p>0.05). There were no statistically significant differences among the four groups regarding patients’ dentin sensitivity to the compressed air. Conclusion: Removal of cervical enamel projections did not increase patients’ dentin sensitivity to compressed air.
