本研究的目的是在探查 II 级和 III 级面部磨牙分叉部位最深的根间袋深度时，从组织学角度确定牙周探针尖端的位置。用设置在50g压力下的压敏探针探测面部分叉袋(5.8mm.±.1.3)。用酸蚀复合树脂将探针尖端固定在牙齿上。手术块活检被取出、固定、脱钙并进行组织学切片处理。从9个活组织检查中切下颊舌连续切片(6μ)，并从3个活组织检查中切下顶冠连续切片。对切片进行组织计量分析。探针尖端刺入发炎的分叉结缔组织的平均深度为2.1毫米(±0.6)。探针尖端位于根间骨顶部 0.4 毫米 (.+-.1.4) 处。探针尖端周围结缔组织 (ICT) 中炎症细胞浸润的百分比为 56% (.+-. 15%)。 ICT 百分比与探头穿透深度之间没有相关性。这项研究表明，对未经治疗的面部磨牙分叉部位进行探测并不能测量根间根表面的附着水平，而是记录探针穿透发炎分叉结缔组织的深度。
The purpose of this investigation was to histologically determine the position of the periodontal probe tip when probing the deepest interradicular pocket depth in grade II and III facial molar furcation sites. Facial furcation pockets (5.8 mm .+-. 1.3) were probed with a pressure-sensitive probe set at 50 g pressure. The probe tip was attached to the tooth with an acid etched composite resin. Surgical block biopsies were removed, fixed, decalcified and processed for histological sectioning. Buccolingual serial sections (6 .mu.) were cut from 9 biopsies and apicocoronal serial sections were cut from 3 biopsies. The sections were histometrically analyzed. The probe tip penetrated the inflamed furcation connective tissue an average depth of 2.1 mm (.+-. 0.6). The probe tip was located 0.4 mm (.+-. 1.4) apical to the crest of the interradicular bone. The % of inflammatory cell infiltrate in the connective tissue (ICT) around the probe tip was 56% (.+-. 15%). There was no correlation between the % of ICT and the depth of probe penetration. This investigation demonstrated that probing of untreated facial molar furcation sites does not measure the attachment level of the interradicular root surfaces, but rather records the depth of probe penetration into the inflamed furcation connective tissue.
