The diagnostician may expect an error associated with the measurements of clinical parameters. It is important to know how precise these measurements are. The purpose of this study was to make an estimation of the measurement error by comparing repeated measures of the same site. Six dental hygiene students were examined for gingival and were recorded twice. The maximum error associated with 95% of the temperature data and the average error were calculated as 1.3 degrees C and 0.65 degrees C, respectively. The probabilities of making a correct assessment of pocket depth and of sulcular bleeding were computed to be 0.864 and 0.840, respectively. The need for repeated measures was statistically analyzed. It can be concluded from our data that the thermocouple thermometer used in this study is a suitable instrument for measuring the gingival temperature. However, it is necessary to acquire a higher level of precision for the assessment of pocket depth and sulcular bleeding. This can be accomplished by increasing the number of clinical measures on each point.
诊断医生可能会预期到与临床参数测量相关的误差。了解这些测量的精确程度很重要。本研究的目的是通过比较同一部位的重复测量来估计测量误差。对六名口腔卫生专业学生的牙龈进行了检查，并记录了两次。与95%的温度数据相关的最大误差和平均误差分别计算为1.3摄氏度和0.65摄氏度。对牙周袋深度和龈沟出血做出正确评估的概率分别计算为0.864和0.840。对重复测量的必要性进行了统计分析。从我们的数据可以得出结论，本研究中使用的热电偶温度计是测量牙龈温度的合适仪器。然而，对于牙周袋深度和龈沟出血的评估，有必要获得更高的精度。这可以通过增加每个点的临床测量次数来实现。
