一次完成与分次完成龈下刮治的短期疗效观察

目的：比较一次完成和分次完成龈下刮治治疗牙周炎的短期临床疗效。方法：30例中度牙周炎患者，进行洁治和口腔卫生指导后随机分为两组，实验组为一次性完成龈下刮治，洗必泰含漱；对照组为传统的分4次完成龈下刮治，每次间隔1周。记录各组刮治前，治疗后6周的改良龈沟出血指数（SBI）、探诊深度（PD）、附着丧失（AL）等相关指标。结果：一次性和分次完成龈下刮治均使SBI、PD、AL等指标明显改善，但实验组与对照组相比较SBI、PD、AL等指标明无统计学差异。结论：一次和分次完成龈下刮治治疗牙周炎疗效肯定，一次性龈下刮治较传统的分次法治疗周期短，复诊次数少，提高患者的依从性，值得在临床上推广。

Observation of Short-term Clinical Effect between FM-SRP and Q-SRP

Objective: To compare the short-term clinical effect of full-mouth subgingival scaling and root planning(FM-SRP) with quadrant scaling and root planning(Q-SRP).Methods: 30 patients with moderate periodontitis patients,were randomly divided into two groups after the scaling and oral hygiene instruction.The experimental group conducted FM-SRP using chlorhexidine rinse.The control group completed the traditional subgingival scaling by 4 times,each separated by 1 week.The related indicators of improved sulcus bleeding index(SBI),probing depth(PD),attachment loss(AL) in each group before and 6 weeks after scaling were recorded.Results: The indicators of SBI,PD,AL improved significantly after FM-SRP and Q-SRP,but there were no statistical difference of these indicators between the experimental group and the control group.Conclusion: The clinical effect of FM-SRP and Q-SRP were sure.However,FM-SRP needs shorter cycle times and fewer referral than Q-SRP,improves the compliance of patients,and should be widly used in clinical practice.
