摘要：

目的 探讨青少年牙齿牙槽骨吸收高度与性别、年龄的关系。 方法 利用多层螺旋CT测量149例10~20岁青少年牙齿唇侧、舌侧、近中侧及远中侧4个位点牙槽骨吸收高度，SPSS 25.0软件分析不同牙齿各侧牙槽骨吸收高度与性别、年龄的关系。 结果 牙槽骨吸收高度在性别间差异无统计学意义（P>0.05），所有类型牙齿牙槽骨吸收高度与年龄呈正相关，4个位点牙槽骨吸收高度联合构建的模型（y=2.569x1+3.106x2+4.108x3+1.451x4-0.082，R2max=0.756）较2个位点联合（y=5.942x1+4.489x2+0.612，R2max=0.706）、单个位点（R2max=0.638）对年龄的推断能力更强。 结论 青少年牙齿牙槽骨吸收高度与年龄呈正相关。4个位点联合对年龄的推断能力更强，于实际应用中拟合效果更好。

Abstract:

Objective To explore the relationship between the height of alveolar bone resorption and sex and age in the adolescent dentition. Methods Multi-slice computed tomography （MSCT） was used to measure the height of alveolar bone resorption at labial, lingual, mesial and distal sites of teeth in 149 adolescents aged from 10 to 20 years. SPSS 25.0 software was used to analyze the relationship between the height of alveolar bone resorption and sex and age. Results There was no significant difference in the height of alveolar bone resorption between sex （P>0.05）. The height of alveolar bone resorption was positively correlated with age in all types of teeth. The model constructed by combining the alveolar bone resorption height data of four sites （y=2.569x1+3.106x2+4.108x3+1.451x4-0.082，R2max=0.756）had a better ability to infer age than that of combining two sites （y=5.942x1+4.489x2+0.612，R2max=0.706） and a single site （R2max=0.638）. Conclusion The height of alveolar bone resorption is positively correlated with the age of adolescents. The combination of four sites has a stronger ability to infer the relationship between the height of alveolar bone resorption and age in adolescents and has higher accuracy in practical application.
