背景资料：探测深度（PD）是一种常用的方法，以确定牙周病的严重程度，在治疗和评估疾病的进展。在科学调查中收集数据的检查者之间的协议是必要的，以建立可靠的标准来确定牙周附着丧失的水平。我们的研究的目的是评估间和intramexaminer之间的变异PD测量研究检查员使用恒力牙周探针，并比较牙齿的平均值和象限mean.Methods的变异性：三个检查员，谁曾接受过培训和校准，进行测量20名志愿者。通过测量标准误（SE）确定研究中心的检查者内和检查者间变异性。数据分析包括象限平均值和牙齿平均值的误差测定。结果：象限平均值的PD测量值用于计算检查者内变异性，导致SE的平均值（SD）为0.40 mm（+/-0.02）。象限平均值的检查者间变异性为0.16 mm（+/-0.02）。对于牙齿平均SE，检查者内变异值等于0.38 mm（+/-0.07），检查者间变异值等于0.24 mm（+/-0.05）。结论：参与我们研究的所有三名检查者都能够使用恒力电子探针获得可靠的PD测量值。与牙齿平均值相比，使用全象限平均值时，生殖力没有明显变化。这些经过培训的检查员能够提供0.5 mm以下的可重复测量。
Background: Probing depth (PD) is a commonly used method to determine periodontal disease severity in both treating and evaluating disease progression. Agreement among examiners collecting data in scientific investigations is necessary to establish reliable criteria for determining levels of periodontal attachment loss. The objective of our study was to evaluate inter- and intraexaminer variability of PD measurements among study examiners using a constant force periodontal probe, and to compare the variability of tooth-mean and quadrant-mean.Methods: Three examiners, who had been previously trained and calibrated, performed measurements on 20 volunteers. Intra- and interexaminer variability of sites was determined by means of standard error of measurement (SE). Data analysis included determination of error for both quadrant mean and tooth mean.Results: PD measurements for the quadrant-mean were used to calculate the intraexaminer variability, resulting in a mean (SD) value for an SE of 0.40 mm (+/-0.02). Interexaminer variability for quadrant mean was 0.16 mm (+/-0.02). For tooth-mean SE, the intraexaminer variability values were equal to 0.38 mm (+/-0.07), and interexaminer variability equal to 0.24 mm (+/-0.05).Conclusions: All three examiners participating in our study were able to obtain reliable measurements for PD, using the constant force electronic probe. Reproducibility did not vary appreciably when using the whole quadrant mean compared to the tooth mean. These trained examiners were able to provide reproducible measures under 0.5 mm.
