Assessment of the validity of the transparency of the periodontal probe as a tool for determining the periodontal phenotype.
The periodontal phenotype was assessed at the six upper anterior teeth of 75 subjects using two methods. One is through assessing the transparency of the periodontal probe upon insertion into the gingival sulcus. The second method was through the assessment and clustering of the width of keratinized gingiva clinically and the gingival and buccal plate thickness on Cone Beam Computed Tomography scan.
The probe transparency approach correctly identified thick periodontal phenotype in most cases (41 out of 43 [95%]). However, this was not the case for thin periodontal phenotype; probe transparency approach identified 64% of the thin sites (261 out of 407) and misclassified nearly one third of the patients.
The probe transparency approach is a valid approach in identifying the phenotype in subjects with thick phenotype but not in subjects with thin phenotype.
The definition of periodontal phenotype has recently changed. Accurate designation has been shown to affect treatment outcomes especially esthetic ones in different disciplines of dentistry. Probe transparency is commonly used by clinicians and researchers. Assessment of the validity of this method based on the most recent definition and compared to actual assessment of bone and gingival thickness is of great clinical value.
评估牙周探针的透明度作为确定牙周表型的工具的有效性。
在 75 名受试者的六颗上前牙上使用两种方法评估牙周表型。一种是通过评估牙周探针插入龈沟时的透明度。第二种方法是通过临床评估和聚类角化龈的宽度以及锥形束计算机断层扫描上的牙龈和颊板厚度。
探针透明度方法在大多数情况下（43 例中的 41 例[95%]）正确识别了厚牙周表型。然而，对于薄牙周表型则并非如此；探针透明度方法识别出 64%的薄部位（407 例中的 261 例），并错误分类了近三分之一的患者。
探针透明度方法在识别厚表型受试者的表型方面是有效的，但在识别薄表型受试者的表型方面则不然。
牙周表型的定义最近发生了变化。在不同的牙科领域，准确指定已被证明会影响治疗结果，特别是美学结果。探针透明度被临床医生和研究人员广泛使用。基于最新定义评估这种方法的有效性，并与实际评估骨和牙龈厚度进行比较，具有重要的临床价值。
