There is presently no satisfactory method of detecting periodontal disease activity at a specified site by means of clinical measurements. This study was designed to examine the possible sources of error with regard to probing measurement reliability. Intra-examiner reproducibility of probing measurements was studied at 766 sites in 10 patients with untreated periodontitis, using a 0.25 N hinged constant force probe (a) with a stent for guidance and landmark, and (b) without stent. The stent made little difference to overall reproducibility of probing depths, though it appeared to reduce variation in different areas. Repeated probing led to an increase in some measurements, perhaps by an effect on tissues. Reproducibility of probing depth was lower in deep pockets, and about 2% of all probing depth scores varied by 3 mm or more at the same site. 4 possible sources of measurement error were noted: visual and tactile observational error, positional error and tissue change. The results are discussed in relation to the clinical detection of periodontal disease activity.
目前还没有通过临床测量在特定部位检测牙周疾病活动的令人满意的方法。本研究旨在探讨探诊测量可靠性方面可能的误差来源。使用0.25 N铰链式恒力探针，对10例未经治疗的牙周炎患者的766个部位进行了检查者内探诊测量的重复性研究，（a）使用带有支架以进行引导和作为标志，以及（b）不使用支架。支架对探诊深度的总体重复性影响不大，尽管它似乎减少了不同区域的变异性。重复探诊导致一些测量值增加，可能是对组织产生了影响。深牙周袋中探诊深度的重复性较低，并且在同一部位所有探诊深度分数中约2%的变化幅度达到3 mm或更大。注意到4个可能的测量误差来源：视觉和触觉观察误差、位置误差和组织变化。结合牙周疾病活动的临床检测对结果进行了讨论。
