This study compares the results of a full mouth examination with the results of examining only the CPITN selection of 10 index teeth 17/16, 11, 26/27, 47/46, 31 and 36/37 for estimates of prevalence and severity of the conditions assessed with the CPITN, i.e. gingival bleeding, dental calculus, pockets 4-5 mm deep and pockets 6+ mm deep. The mean number of sextants recorded with bleeding or with calculus was generally overestimated when examinations were based on the CPITN selection of index teeth, whereas the mean number of sextants with pockets, whether moderate or deep, were generally underestimated. Similarly, the prevalence of pockets, whether moderate or deep, was underestimated in virtually all age groups while the prevalence of calculus was overestimated in all age groups and the prevalence of bleeding was overestimated among persons below 30 yr of age. We conclude that the partial recording approach of the CPITN methodology is reasonably well suited for identifying persons who are relatively healthy according to the hierarchy of the CPITN parameters. There is, however, a considerable risk that persons presenting with the more severe conditions, i.e. pockets, will be overlooked if only partial recordings are performed.
本研究比较了全口检查结果与仅检查10颗指数牙（17/16、11、26/27、47/46、31和36/37）的社区牙周指数（CPITN）选择结果，以评估CPITN所评估状况的患病率和严重程度，即牙龈出血、牙结石、4 - 5毫米深的牙周袋和6毫米及以上深的牙周袋。当基于CPITN指数牙选择进行检查时，记录有出血或有牙结石的牙面平均数量通常被高估，而有牙周袋（无论中度或深度）的牙面平均数量通常被低估。同样，几乎所有年龄组中，中度或深度牙周袋的患病率被低估，而所有年龄组牙结石的患病率被高估，30岁以下人群中出血的患病率被高估。我们得出结论，CPITN方法的部分记录方法相当适合根据CPITN参数等级识别相对健康的人。然而，如果仅进行部分记录，存在相当大的风险，即患有更严重状况（即牙周袋）的人会被忽视。
