【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(P0.05)。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 the gingival thickness in the anterior teeth of Han nationality youth in Shanghai by using conical beam computed tomography (CBCTs). Methods: gingival thickness was measured by gingival puncture and CBCT in 5 subjects at the same site and 30 sites. To compare the measured data, 30 subjects were scanned with CBCT, measured, calculated and analyzed the gingival thickness data of the anterior tooth region (330 sites), compared the gingival thickness between the corresponding sites, and according to the clinical gingival biotype classification, The range and proportion of gingival thickness of different biological types were obtained. The data were analyzed statistically by SPSS 13.0 software. Results: there was no significant difference in gingival thickness between the gums puncture method and the gingival thickness measured by CBCT. The gingival biotypes of young people were mainly thin type and intermediate type. The average gingival thickness of maxillary canine was 1.08 卤0.18 mm, that of maxillary lateral incisor was 1.07 卤0.16 mm, and that of maxillary central incisor was 1.32 卤0.15 mm 路mm. the gingival thickness of maxillary central incisor was greater than that of lateral incisor and canine. Conclusion: the gingival thickness of maxillary central incisor is greater than that of lateral incisor and canine. The main gingival biotypes in Shanghai Han nationality are intermediate type and the thickness type is the least.
