The aim of the study was to examine the association between untreated caries on the crown and root of the tooth with the age, gender and dental attendance in a group of adult. Six general practitioners in the Greater Manchester area agreed to take part. Over a 6-week period they collected clinical and personal data on 270 of their adult patients. No association was found between the mean number of coronal surfaces with caries and age; however, there was more root caries in people over 55 yr. More recurrent caries associated with a restoration was diagnosed than primary caries. There were proportionally more female than male regular attenders, and once attendance has been taken into account there were no gender differences for either coronal or root caries. Both coronal and root caries were associated with attendance, with irregular attenders experiencing more. Irregular attenders were three and a half times more likely to have caries on the root surfaces than regular attenders.
本研究的目的是调查一组成年人中牙齿冠部和根部未经治疗的龋齿与年龄、性别及就诊情况之间的关联。大曼彻斯特地区的六位全科医生同意参与研究。在六周的时间里，他们收集了270名成年患者的临床和个人数据。发现有龋齿的冠面平均数量与年龄之间无关联；然而，55岁以上人群的根面龋更多。与修复体相关的再发龋比原发龋被诊断出的更多。定期就诊者中女性比例高于男性，在考虑就诊情况后，冠龋和根龋在性别上均无差异。冠龋和根龋都与就诊情况有关，不定期就诊者患龋更多。不定期就诊者根面患龋的可能性是定期就诊者的3.5倍。
