摘要
目的比较两种治疗仪在龈下刮治方面的疗效,并对病人的疼痛感受进行评估,以期为临床应用提供参考。方法选取20例慢性牙周炎的病人,采用左右半口对照方法,随机用品瑞PR-ZH1牙科综合治疗仪(A组)和Suprasson P5newtron超声多功能牙科治疗仪(B组)进行龈下刮治。分别于术前和术后1个月记录所选患牙的菌斑指数(PLI)、探诊出血(BOP)指数、探诊深度(PD)和龈下刮治的时间,并于术后即刻采用视觉模拟评分法(VAS)对病人的疼痛进行评估。结果两组治疗前后PLI、BOP指数及PD比较差异均有显著意义(t=5.57~20.82,P<0.01)。两组治疗前后PLI、BOP指数及PD差值比较差异无显著性(P>0.05)。两组龈下刮治时间比较差异无显著性(P>0.05)。两组VAS评分比较差异有显著性(t=3.02,P<0.05)。结论两种治疗仪用于龈下刮治均可取得良好的效果,品瑞PR-ZH1型治疗仪治疗病人产生的疼痛感更轻。
Objective To compare the clinical efficacy and perception of pain during subgingival scaling using PRME PR- ZH1 ultrasonic system versus Suprasson P5 newtron ultrasonic system. Methods Twenty patients with chronic periodontitis were debrided using both PRME PR-ZH1 （group A） and Suprasson P5 newtron （group B） ultrasonic system. The periodontal indi ces （PLI, PD and BOP）, before and one month after subgingival scaling, and the time spent for subgingival scaling were recorded. The pain caused by the treatment was evaluated by VAS right after the procedure. Results The differences between the two groups （one month after treatment） were significant with regard to PLI, BOP and PD （t =5.57-20.82,P〈0.01）, before treat- ment, the differences of the index were not significant （P〉0.05）. The difference of time spent for the treatment between the two groups was not significant （P^0.05）.The VAS of group A was significantly smaller than that of the group B （t=3.02,P〈0.05）. Conclusion Both therapeutic apparatus can get a satisfactory result for subgingival scaling, but PR-ZHI causes less pain.
