Various methods, including clinical and radiographic techniques, can be used to assess periodontal regeneration in interproximal areas. The goal of the present study was to compare the papilla length relative to the alveolar bone crest measured by clinical, intrasurgical, and radiographic techniques.
The study sample included 250 interproximal papillae in 68 patients with generalized chronic periodontitis. The papilla length from the alveolar bone crest was measured clinically (as the actual papilla length, APL), intrasurgically (as the bone probing length, BPL), and radiographically (as the radiographic bone length, RBL). Measurements were standardized by using acrylic resin stents, XCP rinn, a paralleling technique, and/or a radiographic grid.
The mean (± standard deviation) for RBL was 4.9 ± 0.8 mm, BPL was 5.1 ± 0.6 mm, and APL was 5.1 ± 0.6 mm. Correlations between RBL and APL and between BPL and APL were 0.918 and 0.943, respectively (both P < 0.01).
If the clinical recordings are appropriately standardized, then noninvasive radiographic methods can be used to evaluate the papilla length with good accuracy.
包括临床和影像学技术在内的多种方法可用于评估邻面区域的牙周再生情况。本研究的目的是比较通过临床、手术中及影像学技术测量的相对于牙槽嵴顶的龈乳头长度。
研究样本包括68例广泛性慢性牙周炎患者的250个邻面龈乳头。从牙槽嵴顶测量龈乳头长度，采用临床测量法（实际龈乳头长度，APL）、手术中测量法（探骨长度，BPL）和影像学测量法（影像学骨长度，RBL）。使用丙烯酸树脂支架、XCP林恩、平行投照技术和/或放射格栅对测量进行标准化。
RBL的平均值（±标准差）为4.9±0.8mm，BPL为5.1±0.6mm，APL为5.1±0.6mm。RBL与APL之间以及BPL与APL之间的相关性分别为0.918和0.943（均P<0.01）。
如果临床记录经过适当标准化，那么无创影像学方法可用于准确评估龈乳头长度。
