The goal of this study was to determine whether an ultrasonic scaler with a modified tip is as effective as a curet in providing supportive periodontal treatment for patients, based on clinical parameters of periodontal disease. Nine patients with 10 sites exhibiting probing pocket depth > or = 3 mm were treated at 0, 90, and 180 days in a single-blind, split-mouth design for supportive periodontal treatment with either Gracey curets (GC) or an ultrasonic scaler with a modified tip (MU). Clinical parameters included plaque index, gingival index, bleeding on probing, darkfield microscopy, and elastase presence. Probing pocket depths and attachment levels were measured using an electronic probe. Measurements of clinical parameters were taken at 0, 14, 45, 90, 135, and 180 days. The results showed that treatment with MU was as effective as treatment with GC in all clinical parameters measured. Both treatment modalities were effective in reducing the elastase levels. Instrumentation time was significantly reduced with the MU (3.9 minutes vs. 5.9 minutes, P < 0.05). The MU instrument effectively reduced the microbial environment in a significantly shorter time as compared to GC.
