干预措施:

Interventions:

组别:

薄型组

样本量:

4

Group:

Thin phenotype

Sample size:

干预措施:

牙周表型判断方法如下:受试者平躺于椅位,上颌合平面垂直于地面,牙周探针平行于牙冠长轴,轻探入受试牙唇侧中央龈沟,薄型组为牙周探针的轮廓透过牙龈组织可被辨认。

干预措施代码:

Intervention:

The method for determining periodontal phenotype is as follows: The subject lies supine on the chair with the maxillary occlusal plane perpendicular to the ground. The periodontal probe is positioned parallel to the long axis of the tooth and gently inserted into the central gingival sulcus on the labial side of the target tooth. In the thin phenotype group, the contour of the periodontal probe can be discerned through the gingival tissue.
