Aim: The objectives of the present study are to assess the problem of dentin hypersensitivity after non-surgical periodontal treatment with hand and ultrasonic instrumentation. Materials and Methods: For this controlled clinical trial of a “split mouth” design, 15 patients are selected with homologous teeth in the incisor to premolar region and probing depth (PD) ≤5 mm on the buccal aspect of the teeth. One side (control) is instrumented with hand instruments and the other side (test) with ultrasonic instruments for complete scaling and root debridement. Dentin hypersensitivity is assessed at baseline, after 2 weeks, and the 4 weeks after treatment, with an explorer scratching the root surface and with an air jet. Results: The results showed that both periodontal therapies showed the same improvement in the decrease of PD and increase in clinical attachment level. The test group (15 patients) initially presented mean value 4.06 ± 0.70 and at 1 month after treatment, this mean value was reduced to 3.0 ± 0.75. In the control group (15 patients), these values were 4.06 ± 0.79 and 2.80 ± 0.20 before and after treatment, respectively. There were reductions in the sulcus bleeding index during the 4-week follow-up. Hypersensitivity increased statistically only in the control group after stimulation with air and scratch probe test during the 2nd week. After the instrumentation, the occurrence of sensitivity occurred at low levels, and completely disappeared within 4 weeks of evaluation. Conclusion: Despite the limitations of the present study, no differences were observed between manual and ultrasonic instrumentation regarding the occurrence of dentin hypersensitivity after treatment. Only a one change was observed there was increase in sensitivity only in the control group (hand scaling) after stimulation with air and scratch probe test during the 2nd week.
