摘要：  目的 · 采用锥形束计算机体层摄影术（CBCT）检测上海地区汉族青年前牙区的牙龈厚度，初步评价临床应用可行性及牙龈生 物型特点。方法 · 在同一位点（5 名受试者，30 个位点）分别采用牙龈穿刺法和 CBCT 检测牙龈厚度，对测量数据进行比较。对 30 名受试者进行全颌 CBCT 扫描，测量、计算并分析前牙区（330 个位点）牙龈厚度数据，对相应位点间的牙龈厚度进行比较；根据临 床牙龈生物型的分型，获得不同生物型的牙龈厚度范围及比例。采用 SPSS 13.0 软件对所得数据进行统计学分析。结果 · 牙龈穿刺法 与 CBCT 测得的牙龈厚度的差异无统计学意义 (P>0.05)。上海地区汉族青年人群牙龈生物型以薄型和中间型为主；其中上颌尖牙牙龈 厚度平均为（1.08±0.18）mm，上颌侧切牙牙龈厚度平均为（1.07±0.16）mm，上颌中切牙牙龈厚度平均为（1.32±0.15）mm。统计 学分析结果显示，上颌中切牙牙龈厚度大于侧切牙和尖牙，差异具有统计学意义（P=0.000，P=0.000）。 结论 · CBCT 可作为检测牙龈 厚度的可靠方法。上颌中切牙牙龈厚度大于侧切牙和尖牙。上海地区汉族青年人群牙龈生物型以中间型为主，厚型最少。

Abstract:

Objective · To detect gingival thickness of the anterior teeth region of Han nationality youths in Shanghai by cone-beam computerized tomography (CBCT), and evaluate its clinical application feasibility and the gingival biotype.  Methods · Firstly, gingival thickness in the same site (5 participators, 30 sites) was detected by bone sounding and CBCT respectively, and the data were compared. A total of 30 participators with healthy gingival were recruited to the study and examined by the CBCT, the gingival thickness of selected sites (330 sites) was assessed and compared. All the subjects were examined by the experienced doctors and classified into three groups, “thick-type” “middle-type” and “thin-type”. Gingival thickness range and the proportion of every type were obtained. All data analyses were performed using SPSS 13.0.  Results · There was no statistical difference in the thickness of gingival measured by bone sounding and CBCT (P>0.05). The main gingival biotypes of Han nationality youths in Shanghai were “thin-type” and “middle-type”. The average gingival thickness of upper central incisors [(1.32±0.15） mm] was larger than those of upper lateral incisors [(1.07±0.16) mm, P=0.000] and upper canines [(1.08±0.18) mm, P=0.000].  Conclusion · CBCT is feasible for detecting gingival thickness. Gingival thickness of the upper central incisors is significantly larger than those of upper lateral incisors and upper canines. The main gingival biotype of Han nationality youths in Shanghai is “middle-type”, the proportion of “thick-type” is least.
