The assessment of clinical attachment level (CAL) represents the gold standard for diagnosing and monitoring periodontal disease. The aim of the present study was to evaluate the performance of the newly introduced cemento-enamel junction (CEJ) probe in detecting CAL, using CEJ as a fixed reference point, and to compare the CEJ probe with the Florida stent probe (FSP) as well as with a standard manual probe, University of North Carolina-15 (UNC-15).
Three examiners recorded the probing attachment level in 384 sites in case group (chronic periodontitis), and in 176 sites, in control group (healthy periodontal status), using the three probes. Subjects included both the sexes and ranged from 35 to 45 years. The experimental design was structured to balance the intra- and inter-examiner consistency at the same site during the two visits.
CEJ probe showed higher intra-and inter-examiner consistency over both FSP and UNC-15 in both the case and control groups. Frequency distribution of differences of various magnitudes of repeated measurements ≤1 mm was in the higher range of 86.8% to 87.5% for CEJ probe. The FSP was more reproducible than UNC-15 in detecting relative attachment level (RAL).
CEJ automated probe was found to have greatest potential for accuracy and consistency in detecting CAL than FSP and UNC-15. The automated probes appeared to be more reproducible than manual probes.
临床附着水平（CAL）的评估是诊断和监测牙周疾病的金标准。本研究的目的是评估新推出的牙骨质-釉质界（CEJ）探针以CEJ作为固定参考点检测CAL的性能，并将CEJ探针与佛罗里达支架探针（FSP）以及标准手动探针北卡罗来纳大学15号探针（UNC-15）进行比较。
三名检查者使用这三种探针记录了病例组（慢性牙周炎）384个位点以及对照组（牙周健康状态）176个位点的探诊附着水平。受试者包括男性和女性，年龄在35至45岁之间。实验设计旨在平衡两次就诊期间同一部位检查者内部和检查者之间的一致性。
在病例组和对照组中，CEJ探针在检查者内部和检查者之间的一致性均高于FSP和UNC-15。对于CEJ探针，重复测量差异≤1mm的各种幅度的频率分布在较高范围，为86.8%至87.5%。在检测相对附着水平（RAL）方面，FSP比UNC-15更具可重复性。
发现CEJ自动探针在检测CAL方面比FSP和UNC-15具有更高的准确性和一致性潜力。自动探针似乎比手动探针更具可重复性。
