【摘要】：目的:测量上颌前牙唇侧黏膜厚度,分析其与性别及体质量指数(BMI)的相关性。方法:选择健康汉族青年男45人,女55人为研究对象,推开唇颊组织,用锥形束CT对颌面部扫描并三维重建,测量上颌前牙唇侧龈缘至牙槽嵴顶牙龈及牙槽嵴顶至其根方3 mm范围的黏膜厚度和龈缘至牙槽嵴顶的牙龈宽度。分析黏膜厚度的性别组间差异及与BMI的相关性。结果:受试者总体在牙长轴纵切面上,中切牙、侧切牙和尖牙唇侧龈缘至牙槽嵴顶的黏膜厚度(mm)分别为1.32±0.20、1.10±0.24、1.21±0.19;牙槽嵴顶至其根方3 mm范围的黏膜厚度(mm)分别为0.69±0.17、0.52±0.16、0.59±0.15;牙龈宽度(mm)分别为3.18±0.45、3.00±0.44和3.07±0.40。上颌前牙唇侧牙槽嵴顶至其根方3 mm范围的黏膜厚度男性大于女性(P0.05),与黏膜厚度BMI显著正相关(r=0.376,P0.05)。结论:①上颌前牙区唇侧牙龈厚度呈冠根向递增趋势,唇侧牙龈厚度大于牙槽黏膜厚度;②男性牙槽黏膜厚度显著大于女性;③牙槽黏膜厚度与体质量指数显著正相关。
[Abstract]:Objective: to measure the thickness of labial mucosa of maxillary anterior teeth and to analyze its correlation with sex and body mass index (BMI). Methods: 45 healthy young Han males and 55 females were selected as subjects to open the labial and buccal tissues. Conical beam CT was used to scan and reconstruct maxillofacial region. The mucosal thickness of the labial margin to the top of the alveolar crest and the width of the gingival between the gingival margin and the alveolar crest of the maxillary anterior teeth were measured in the range of 3 mm from the top of the alveolar ridge to the top of the alveolar crest, and the difference of the mucosal thickness between the two groups and the correlation between the mucosal thickness and BMI were analyzed. Results: the subjects were generally on the longitudinal plane of the long axis of the tooth. Central incisors, The mucosal thickness of lateral incisor and canine labial margin to alveolar crest were 1.32 卤0.201.10 卤0.241.21 卤0.19, 0.69 卤0.170.52 卤0.160.59 卤0.15, and 3.18 卤0.453.00 卤0.44 and 3.07 卤0.40, respectively. The mucosal thickness from the top of alveolar ridge to its root was 0.69 卤0.170.52 卤0.160.59 卤0.15; and the width of gingival was 3.18 卤0.453.00 卤0.44 and 3.07 卤0.40, respectively. The thickness of mucous membrane in 3 mm range of root side in male was larger than that in female (P0.05), and there was a significant positive correlation with mucosal thickness (BMI). Conclusion the thickness of labial gingival in the maxillary anterior tooth area increases in a coronal and root direction. The thickness of labial gingiva was greater than that of alveolar mucosa. (2) the thickness of alveolar mucosa in males was significantly higher than that in females. There was a significant positive correlation between the thickness of alveolar mucosa and body mass index (BMI).
