Dentin hypersensitivity after manual and ultrasonic scaling

Introduction: This study aimed to evalua te the dentinal hypersensitivity (DH) after manual and ultrasonicscaling.Materials and Methods: In this study ۹۰ ۰ teeth were assessed. Plaque index and gingival recession weremeasured. Prior to scaling and root planning (SRP), DH was measured clinically using a periodontal probe andair jet. The patients reported the discomfort using the Visual Analogue Scale (VAS). Later the teeth in the twoopposite quadrants were manually scaled and the other two quadrants were ultrasonically scaled. After ۲weeks, DH was reevaluated with the same two methods. The data were analyzed using the SPSS.Results: The DH of ۹۰۰ teeth in ۳۴ patients was included. ۶۷.۶% (۲۳) of participants reported pre scaling DHand ۸۵.۳% (۲۹) experienced post scaling DH. The prevalence of DH had no significant difference before andafter SRP in manual group and ultrasonic group. Also, after SRP, no significant difference was observedbetween manual and ultrasonic scaling.Conclusion: Manual and ultrasonic methods did not increase DH after SRP compared to baseline. Post scalingDH was not signi ficantly different between the manual and ultrasonic SRP. DH was related to gingivalrecession. So that, pre and post scaling DH were higher in patients with gingival recession.
