However, piezoelectric instruments gave smoother root surface than hand instruments and were also more efficient in calculus removal. Both SEM and profilometric analysis showed that Piezoelectric scaler A and Piezoelectric scaler B caused less root surface roughness compared to hand instruments.Ĭonclusion: The findings of the present study suggest that scaling and root planing using both piezoelectric scalers and hand instruments were effective in mechanical debridement of the root surface. There was significant difference in mean Loss of tooth substance index(LTSI) and Roughness loss of tooth substance index (RLTSI) scores when compared in the three groups (p value =0.002). Piezo Ultrasonic Scalers operate using precise, single-plane liner oscillations to ensure that patient mucosal tissue remains undamaged. Perform normal ultrasonic scaling with the added. Results: Statistically significant difference was observed in Remaining calculus index (RCI) in the three experimental groups with hand instrument being least effective in removing calculus when compared to the piezoelectric scalers(p?0.05). Ultrasonic scaler with regular, endo, and perio frequencies Woodpecker's UDS-L LED Piezo Ultrasonic Scaler packs functionality and value into one unit. Specimens were subjected to Scanning Electron Microscopy (SEM) & Profilometric analysis to evaluate the root surface roughness created by these three instruments. Group 1,Group 2 and Group 3 where instrumentation was done using two piezoelectric scalers- Piezoelectric scaler A & Piezoelectric scaler B and Gracey curette respectively. They were divided into three groups of 30 teeth each i.e. Methods: 90 freshly extracted non-carious, non-restored single rooted teeth with hopeless periodontal prognosis were included in the study.
