摘要
目的 评价65 μm甘氨酸颗粒喷砂抛光方法对牙周炎维护期患者的临床效果并与传统的维护方法比较,以便为进入牙周维护期的患者寻求一种有效、省时且舒适度较高的治疗方法.方法 纳入全身健康、进入牙周治疗维护期的患者23例,采用自身的分口对照设计,试验侧使用65 μm甘氨酸颗粒喷砂抛光（试验组）,对照侧采用超声洁治＋抛光进行维护治疗（对照组）,分别记录维护治疗前和12周后各项临床指标,以及两种方法操作中患者舒适度和所需操作时间,比较分析两种方法的临床效果.结果 两种方法治疗后12周的各项临床指标（探诊深度、出血指数、菌斑指数等）均较基线有明显好转,但两种方法各项临床指标间差异均无统计学意义.患者舒适度评分和临床操作时间试验组[分别为（1.7±1.3）和（192.7±82.7）s]均显著优于对照组[分别为（3.3±1.8）和（345.4±116.9）s],差异均有统计学意义（P＜0.01）.结论 对牙周维护期的患者使用65 μm甘氨酸颗粒喷砂抛光可以达到与传统维护治疗方法相近的临床效果,同时还具有省时、舒适度高的优点.
Objective To evaluate the clinical effect of the 65 μm glycine powder air-polishing （GPAP） and ultrasonic scaling during periodontal maintenance phase.Methods Twenty-three patients at the age of 28-72（8 males and 15 females） who were systematically healthy were involved in this study.According to splitting-mouth design,one side of a mouth was randomly assigned to the experiment group with 65 μm GPAP therapy,while the other side was the control group with ultrasonic scaling therapy.The clinical parameters including probing depth（PD）,bleeding index（BI）,gingival recession（Rec）,plaque index （PLI）,staining index（SI） were recorded.The patients＇ perception of treatment was assessed by visual analogue scale（VAS）.The treatment time was recorded and compared between the two groups.Results Both of the two methods had good clinical effects.PD,BI and PLI of the two groups 12 weeks after treatment were better than those at baseline（P〈0.01）.There was no significant deference between the two methods at baseline and at the 12 weeks after treatment.The VAS value of experiment group was better than that of control group（1.7± 1.3 vs.3.3± 1.8,P〈0.01）.The treatment time of experiment group was also shorter than that of control group[（192.7±82.7） s vs.（345.4± 116.9） s,P〈0.01].Conclusions The results indicate that 65 μm GPAP may be as effective as the ultrasonic scaling during periodontal maintenance phase.65 μm GPAP had the advantage of more comfort and less time consuming.
