摘要 目的研究广东省6~15周岁人群牙齿钙化的规律,建立根据牙齿钙化程度推断未成年人年龄的方法。方法观测2 710例(男性1 363例,女性1 347例)广东省6~15周岁汉族人全口曲面断层影像片,对其下颌牙齿钙化程度进行评分分级,所得数据经SPSS软件统计分析,建立根据牙齿钙化程度推断年龄的方程,并以100例(男60例、女40例)研究外样本进行盲测。结果数据统计显示,两侧同名牙钙化评分分级值的差异无显著性意义(P>0.05),而性别间差异有显著性意义(P<0.05);下颌单侧8颗牙齿的钙化评分分级值与年龄相关系数(r)女性为0.552~0.759,男性为0.672~0.838;所建回归模型拟合优度(R2)均在0.7以上,估计值标准误男性为0.91~1.11岁,女性为0.92~0.98岁;盲测推测年龄与真实年龄平均误差男性为0.429±0.282岁、女性为0.399±0.252岁。结论本研究所建方法推断结果准确可靠,可用于广东地区6~15周岁人群年龄推断。 Objective To observe explorer the development of dental calcification through orthopantomographs collected from the groups aged 6~15 years old in Guangdong province,then to set up methods for age estimation.Methods Referring to the reported standard to grade the stage of low mandibular dental calcification showing in the digital orthopantomograms belonging to 2 710(male 1 363,female 1 347)samples aged 6~15 years old in Guangdong,and deal the figure with SPSS 13.0 and set up equations for age estimation,then to do blind test based on 100 samples(male 60,female 40).Results There are no significant statistic differences in the low mandibular dental calcification stage between sides,but the differences do exist between gender;meanwhile,there is a good relation between chronological age and dental calcification;the blind test proves that the method used in this study is practical.Conclusion The method set up in this study will play an important role in estimating age for Chinese Han nationality adolescents aged from 6 to 15 years old in Guangdong.
