摘　　要：目的运用全口曲面断层影像技术,研究陕西省6-15岁汉族未成年人牙齿钙化规律,建立利用牙齿钙化程度推断陕西汉族6-15岁未成年人年龄的方法。方法按照中国汉族儿童及青少年牙齿钙化分级标准,对1997名（男934名,女1063名）陕西省6-15岁汉族未成年人的全口曲面断层影像中下颌恒牙钙化程度进行分级评分;将所得评分值及对应的年龄输入SPSS软件并进行统计分析,最终建立年龄推断的方程。结果下颌同名牙钙化评分值侧别间非参数检验结果 P〉0.05,而性别间非参数独立样本检验结果 P〈0.05;下颌左侧各颗恒牙钙化程度与年龄相关分析结果 r〉0.59;方程拟合优度检验所得校正决定系数均大于0.76,估计值标准误男性在0.85-1.05岁之间、女性在0.83-0.97岁之间。结论本研究建立的方法合理可靠,可用于陕西省汉族6-15岁未成年人年龄的推断。Objective To establish a method of age estimation for Han nationality adolescents aged from 6 to 15 years old in Shanxi.Methods 1997 digital orthopantomograms（934 male and 1063 female） of Han nationality adolescents aged from 6 to 15 years old in Shanxi were observed and graded,then the grading scores were analyzed with SPSS13.0.Results The P-value of non-parameter test for the scores of dental calcification between homonymic teeth were above 0.05,but it was opposite between gender,each coefficient of correlation between the age and the dental calcification was above 0.59,all of the adjusted R2 for the equations were above 0.76,the standard error of estimate is 0.85 to 1.05 years for male and 0.83 to 0.97 year for female.Conclusion The method established in this study was reasonable and reliable,and it can be used to estimation the age of adolescents in Shanxi.
