Indices used to evaluate periodontal health have been widely accepted in epidemiological studies, yet their reliability cannot be guaranteed. The aim of this study was to evaluate the reliability of periodontal indices applied on elders. 19 elderly subjects, 73-years-old on average, were examined at a 1st appointment by 2 independent examiners. They were re-examined 2 weeks later during a 2nd session. The examinations were performed in a dental chair with good illumination. Periodontal health was evaluated using the community periodontal index of treatment need, and tooth mobility was evaluated using 2 different indices. Inter and intra-examiner agreements were evaluated using kappa statistics. Taken as an overall measurement, the CPITN was a reliable assessment of periodontal treatment need in elders. Disagreement occurred mainly on the evaluation of bleeding and shallow pockets. The detection of fairly mobile teeth was reliable; however, the performance of the more sensitive scale was deceptive. it seems that, in the case of tooth mobility, a choice has to be made between sensitivity or reproducibility. It can be concluded that examiners should be trained carefully since the reliability of the CPITN and tooth mobility evaluation were good but close to a critical level for which an agreement is classified as poor.
用于评估牙周健康的指标在流行病学研究中已被广泛接受，但其可靠性无法得到保证。本研究的目的是评估应用于老年人的牙周指标的可靠性。19名平均年龄为73岁的老年受试者在第一次就诊时由2名独立检查者进行检查。两周后在第二次就诊时对他们进行了重新检查。检查在照明良好的牙科椅上进行。使用社区牙周治疗需要指数评估牙周健康状况，并使用2种不同的指数评估牙齿松动度。使用kappa统计量评估检查者之间和检查者内部的一致性。作为一项总体测量，社区牙周治疗需要指数是对老年人牙周治疗需求的可靠评估。分歧主要发生在出血和浅袋的评估上。对相当松动牙齿的检测是可靠的；然而，更敏感量表的表现具有欺骗性。似乎在牙齿松动度方面，必须在敏感性和可重复性之间做出选择。可以得出结论，由于社区牙周治疗需要指数和牙齿松动度评估的可靠性良好，但接近被归类为差的一致性的临界水平，因此应对检查者进行仔细培训。
