摘　　要：目的 检验牙周探诊法判断牙龈生物型的准确性.方法 选择牙龈健康、20～30岁之间的青年14人（男6人,女8人）,共66颗上颌前牙.通过判断牙周探针在探入的牙龈组织内轮廓是否清晰定性判断上颌前牙牙龈生物型；使用锥形束CT测量上颌前牙唇侧中央釉质牙骨质界处牙龈厚度,并分析其相互关系.结果 牙周探诊法判断牙龈生物型的方法具有良好的一致性（一致率为80％,Kappa=0.699）和可重复性（一致率为88％,Kappa=0.815）；牙周探诊法定性判断牙龈生物型与锥形束CT定量测量牙龈厚度的结果一致,薄型、中间型、厚型3种牙龈的平均厚度分别为（1.02±0.20）、（1.28 ±0.25）和（1.46±0.25） mm,三者间差异有统计学意义（P =0.001）.结论 牙周探诊法判断牙龈生物型是一种简便、相对客观、适用于临床的检查方法.Objective To establish a convenient,objective and applicable method to assess gingival biotype using periodontal probing.Methods A total of 66 maxillary anterior teeth from 14 volunteers （6 males,8 females） with healthy gingiva,aged from 20 to 30 years,were recruited in this study.The gingival biotypes were evaluated by whether or not the outline of the periodontal probe was clear inside the gingiva.Gingival thickness of the cement6-enamel junction（CEJ） in upper anterior teeth was measured by cone-beam CT （CBCT）.Results The method of periodontal probing-assessed gingival biotype had good consistency and repeatability. The result of probing-assessed gingival biotype was consistent with that obtained by CBCT. The mean thickness of gingiva in thin,compromised and thick gingival biotype was （ 1.02 ± 0.20）,（ 1.28 ± 0.25 ） and （ 1.46 ± 0.25 ） mm.These differences were significant for all three comparisons（ P =0.001,respectively）.Conclusions Periodontal probing-assessed gingival biotype is a simple,relatively objective and suitable method for clinical examination.
