Abstract

<p> Purpose: Calculus removal is essential for periodontal treatment. The scaling is performed using many types of scalers. The main sources of power used in dentistry at present are hand, air and ultrasound. To resolve the problems of these scalers, we developed a vibrating scaler using an electric rotating mass. The purpose of this study was to evaluate the clinical effectiveness of the vibrating scaler in comparison with a hand scaler.</p><p> Methods: This study was approved by the Review Board of Tohoku University Hospital Institution. The subjects were 20 patients with slight or moderate periodontitis. We examined the left and right paired same-name teeth in the same jaw. One tooth was scaled by the vibrating scaler, and the other tooth was scaled by hand.</p><p> Results: Each examination of calculus index showed a score of zero. The total treatment time of the vibrating scaler was slightly shorter than that of the hand scaler. Patients' pain VAS showed a decreasing tendency, but there was no significant difference in the doctor's fatigue VAS between the two groups. Though we found no difference between the two groups, PPD and BOP showed a significant decrease. We found a significant decrease only on GI at one week using the vibrating scaler. There was no difference between the two groups in the number of bacteria.</p><p> Conclusion: These results indicated that the vibrating scaler had an equal ability to remove calculus as the hand scaler.</p>
