干预措施:

局麻下于邻牙颊侧轴角处行垂直切口,切口越过膜龈联合;翻瓣时应在完整保留龈乳头的同时,暴露骨缺损

干预措施代码:

Intervention:

Under local anesthesia, a vertical incision was made on the buccal side of the adjacent tooth at the apical angle, crossing the junction of the mucosa and the gingiva. During the flap dissection, while completely preserving the gingival papilla, the bone defect should be exposed.

干预措施代码:

Intervention:

Under local anesthesia, at the position corresponding to the gingival papilla in the bone defect, a modified or simplified incision to preserve the gingival papilla is made based on the width of the adjacent space; the buccal and lingual flaps are lifted.

测量指标:

Outcomes:

指标中文名:

临床附着水平变化量

指标类型:

主要指标

Outcome:

Clinical attachment level, CAL

Type:

Primary indicator

测量时间点:

基线、术后6个月、术后1年

测量方法:

使用UNC-15牙周探针(The University of North Carolina-15 probes)探查龈沟底/牙周袋底到釉牙骨质界(Cementoenamel Junction,CEJ)的距离。每颗牙记录六个位点(远中颊侧、颊侧中央、近中颊侧、近中舌侧、舌侧中央、远中舌侧),将骨缺损所在区域涉及位点之中的CAL最大值作为该病损的基线CAL值,相应位点同样作为今后复查时的测量位点。

Measure time point of outcome:

Baseline, 6 months, and 1 year after surgery

Measure method:

The gingival sulcus/periodontal pocket base to the cementoenamel junction (CEJ) was probed using UNC-15 probes. Six sites were recorded for each tooth (distobuccal, midbuccal, mesiobuccal, mesiolingual, midlingual, and distolingual). The maximum CAL value among the sites involved in the bone defect area was taken as the baseline CAL value for that defect, and the corresponding sites were similarly designated as the measurement sites for subsequent follow-up examinations.
