The aim of this study was to investigate the relationships between gingival thickness (GT) and keratinized gingiva width (KGW), papilla height (PH), and crown ratio (CR) by employing transgingival probing and an intraoral scanner (IOS).
This cross-sectional study examined 360 maxillary anterior teeth from 60 patients. GT was assessed using transgingival probing with an endodontic spreader. KGW, CR, and PH were measured using an IOS. One-way analysis of variance, the Student's -test, and Spearman correlation coefficients were employed for statistical analysis.
Higher GT was significantly associated with thinner KGW in the central region (=0.019). There was no statistically significant difference in GT between teeth (=0.06). PH was lower in lateral teeth than in canines (=0.047), with a PH of 2.99 mm in lateral teeth. The KGW was narrower in canines than in central teeth (=0.007). A moderate correlation was observed between KGW and PH in the central region (=0.01), while a weak negative correlation was found between KGW and CR (=0.043).
A moderate negative correlation was found between GT and KGW, as well as between PH and KGW in central teeth. In contrast, a weak negative correlation existed between CR and KGW. The PH (2.99 mm) was lower in lateral teeth than in canines. The traditional paradigm, which suggests a positive correlation between KGW and GT, was re-evaluated by measuring KGW using an IOS.
本研究旨在通过龈下探查和口腔内扫描仪（IOS）研究牙龈厚度（GT）与角化龈宽度（KGW）、龈乳头高度（PH）和冠根比（CR）之间的关系。
这项横断面研究检查了60名患者的360颗上颌前牙。使用根管扩大器进行龈下探查评估GT。使用IOS测量KGW、CR和PH。采用单因素方差分析、Student's -检验和Spearman相关系数进行统计分析。
在中央区域，较高的GT与较薄的KGW显著相关（P = 0.019）。牙齿之间的GT无统计学显著差异（P = 0.06）。侧切牙的PH低于尖牙（P = 0.047），侧切牙的PH为2.99 mm。尖牙的KGW比中央牙窄（P = 0.007）。在中央区域，KGW与PH之间观察到中度相关性（P = 0.01），而KGW与CR之间发现弱负相关性（P = 0.043）。
在中央牙中，GT与KGW之间以及PH与KGW之间发现中度负相关。相比之下，CR与KGW之间存在弱负相关。侧切牙的PH（2.99 mm）低于尖牙。通过使用IOS测量KGW，对KGW与GT之间呈正相关的传统范式进行了重新评估。
