摘要/Abstract

摘要： 目的: 评价角化龈宽度（KTW）对牙周组织再生术治疗骨下缺损临床效果的影响。方法: 回顾性分析行牙周组织再生术治疗骨下缺损的14例患者（44个位点）基线和术后2年随访时的临床资料。以基线时的KTW进行分组,分为KTW>2 mm组及KTW≤2 mm组,采用SPSS 25.0软件包对2组的牙周临床指标进行统计学分析。结果: 组内比较发现,2组术后探诊深度（PD）及临床附着丧失（CAL）水平较术前显著减小（P<0.05）;组间比较2组术后与术前基线时的PD变化值（△PD）及CAL变化值（△CAL）,发现2组之间△PD无统计学差异;但KTW>2 mm组的△CAL显著大于KTW≤2 mm组（P<0.05）。结论: 牙周组织再生术治疗骨下缺损能够有效减轻牙周炎症,减小牙周袋深度,获得附着水平增加。但当KTW不足时（≤2 mm）,手术所获得的附着水平再生有限,再生手术治疗的效果欠佳。

Abstract: PURPOSE: To evaluate the effect of keratinized tissue width (KTW) on periodontal regenerative surgery for the treatment of intrabony defects. METHODS: The clinical data of 14 patients (44 intrabony defect sites) treated with periodontal regenerative surgery were retrospectively analyzed at baseline and 2-year of follow-up. Forty four sites were divided into KTW2 mm group and KTW≤2 mm group according to KTW at baseline. Periodontal clinical indicators of the 2 groups were analyzed by SPSS 25.0 software package. RESULTS: At 2-year post-treatment, probing depth (PD) and clinical attachment loss (CAL) in the 2 groups were decreased significantly compared with those at baseline(P<0.05). There was no significant difference in ΔPD, but △CAL in KTW2 mm group was significantly greater than that in KTW≤2 mm group. CONCLUSIONS: Periodontal regenerative surgery for the treatment of intrabony defects can effectively reduce periodontal pocket inflammation, decrease periodontal pocket depth and increase the level of attachment. When the width of the keratinized gingiva is insufficient(KTW≤2 mm), the regeneration of the attachment level obtained by surgery is limited, and the efficacy of regenerative surgery is poor.
