Abstract

Abstract: PURPOSE: To evaluate the efficacy of traditional manual scaling and piezoelectric and magnetostrictive ultrasonic scaling in regard to periodontal pocket depth and power setting. METHODS: Thirty extracted human molars were assigned to receive manual scaling or ultrasonic scaling (both on the full or half power setting) with probing depth of 5 and 7 mm for 2 min. The remained oil materials on the roots were calculated as supplementary data. The data were compared using SAS6.12 software package. RESULTS: The procedures of ultrasonic scaling resulted in reductions of the values than manual scaling in all groups. The data of the magnetostrictive group were significantly smaller than the piezoelectric group in 5 mm pocket depth (P<0.01) on full power setting, while the opposite in 7 mm pocket depth. There was no significant difference between piezoelectric and magnetostrictive scaling in both 5 mm (P=0.217) and 7 mm (P=0.574) pocket depth on half power setting. The data increased significantly from 5 to 7 mm pocket depth (P<0.01), but no significant influence on different power settings. CONCLUSIONS: The study indicates that ultrasonic scaling instruments are more effective than a hand curette and the scaling efficacy decreased in deeper periodontal pocket.The results reveal no significant difference between magnetostrictive and piezoelectric ultrasonic instruments whether on half or full power settings.
