Abstract：Objective: To compare the effect of Gracey scaler and periodontal ultrasonic therapeutic apparatus in the treatment of periodontitis. Methods: 80 periodontitis patients were randomly divided into a control group and an observation group according to random number table and 40 cases in each group. Gracey traditional manual scaler was used in the control group and Vector periodontal ultrasonic therapeutic apparatus were used in the observation group. The dental plaque index (PLI) , probe depth (PD) , gingival index (GI) and clinical attachment loss (CAL) and VAS were compared. Results: One month after the treatment, dental plaque index( PLI), probe depth (PD) and clinical attachment loss (CAL), gingival index(GI) were both improved and the difference was statistically significant (P ＜ 0. 05) , the PLI, GI and PD in the observation group were better than that in the control group (P ＜ 0. 05) . The VAS were both reduced in two groups and the difference was statistically significant (P ＜ 0. 05) , and the VAS in the observation group reduced more than that in the control group (P ＜ 0. 05) . Conclusion: Both of Gracey scaler and periodontal ultrasonic therapeutic apparatus has sound effect for periodontitis, periodontal ultrasonic therapeutic apparatus has better effect and it is of high clinical application value.
