在日本多机构协作队列（J-MICC研究）中通过问卷调查口腔状况和牙齿数量。本研究的目的是通过比较自我报告的牙齿数量与临床牙科检查确定的牙齿数量来评估牙齿数量测量的有效性。一个自我管理的问卷调查和牙科检查进行了1275名参与者的公司体检谁要求牙科检查和377名受试者的J-MICC研究。通过将自我报告的牙齿数量与临床检查确定的牙齿数量进行比较，评估牙齿数量测量的有效性。计算斯皮尔曼等级相关系数定量评价其效度。在男性中，平均临床检查和自我报告的牙齿数量分别为26.5和24.8颗牙齿。在女性中，平均临床检查和自我报告的牙齿数量分别为26.4和25.5颗牙齿。有一种倾向，低估了自我报告的自然牙齿的数量。临床检查和自我报告的牙齿总数（ρ = 0.69）之间存在显著相关性，男性（ρ = 0.70）和女性（ρ = 0.67）之间也存在显著相关性。自我报告的口腔健康变量是有效的，反映了临床状态。进一步修订问卷中关于剩余牙数的问题，提高了自报牙数的效度。
Oral condition and number of teeth were investigated by questionnaire in the Japan Multi-Institutional Collaborative Cohort (J-MICC Study). The aim of the present study was to assess the validity of the tooth number measure by comparing the self-reported number of teeth with the number of teeth determined at clinical dental examination. A self-administered questionnaire and dental examination were performed by 1275 participants of a company medical examination who requested dental check-up and 377 subjects of the J-MICC study. The validity of the tooth number measure was assessed by comparing the self-reported number of teeth with that determined at clinical examination. Spearman’s rank correlation coefficient was calculated to quantitatively evaluate the validity. In males, the mean clinically-examined and self-reported numbers of teeth were 26.5 and 24.8 teeth, respectively. In females, the mean clinically-examined and self-reported numbers of teeth were 26.4 and 25.5 teeth, respectively. There was a tendency toward underestimation of the number of natural teeth by self-reporting. A significant correlation was observed between the clinically-examined and self-reported numbers of teeth in total (ρ = 0.69) and both males (ρ = 0.70) and females (ρ = 0.67). The self-reported oral health variables were valid and reflected clinical status. Further revision of the question on the remaining tooth in the questionnaire improves the validity of self-reported number of teeth.
