BACKGROUND/PURPOSE: Gingival tissue firmness cannot be objectively assessed or monitored in real-time in existing examinations. This study was designed to examine the potential utility of shear wave elastography (SWE) as a means of evaluating and monitoring gingival inflammation in an effort to assess the effects of initial periodontal therapy in patients with advanced periodontitis.
This pilot study included analyses of 66 sites in 6 advanced periodontitis patients. Patients underwent the SWE examination of the gingiva at the mid-labial and interdental papillae at baseline and at 2, 4, and 6 weeks following initial periodontal therapy. Measured periodontal parameters in these patients include Plaque index (PI), Gingival bleeding index (GBI), Probing depth (PD), and Clinical attachment loss (CAL).
Respective baseline SWE values at the mid-labial gingiva and interdental papilla 25.68 ± 6.82 kPa and 26.78 ± 6.20 kPa, with no significant differences between these two measures. A significant negative correlation between SWE and both PI (r = -0.350, = 0.004) and GBI (r = -0.287, = 0.020) was observed at baseline. Initial periodontal therapy contributed to significantly higher SWE values and tougher gingiva, particularly during the first two weeks. Postoperative changes in SWE were negatively correlated with SWE values at baseline (r = -0.710, < 0.001).
These results establish SWE as a sensitive noninvasive approach to quantitatively assessing changes in gingival elasticity in real-time.
背景/目的：在现有的检查中，牙龈组织硬度无法进行客观评估或实时监测。本研究旨在探讨剪切波弹性成像（SWE）作为评估和监测牙龈炎症的一种手段的潜在效用，以评估初始牙周治疗对晚期牙周炎患者的疗效。
这项前瞻性研究分析了6例晚期牙周炎患者的66个部位。患者在基线时以及初始牙周治疗后2周、4周和6周，接受了唇侧中部和牙间乳头处牙龈的SWE检查。这些患者测量的牙周参数包括菌斑指数（PI）、牙龈出血指数（GBI）、探诊深度（PD）和临床附着丧失（CAL）。
唇侧中部牙龈和牙间乳头处的基线SWE值分别为25.68±6.82 kPa和26.78±6.20 kPa，这两种测量方法之间无显著差异。在基线时，观察到SWE与PI（r = -0.350，P = 0.004）和GBI（r = -0.287，P = 0.020）均呈显著负相关。初始牙周治疗导致SWE值显著升高，牙龈更硬，尤其是在最初两周。SWE的术后变化与基线时的SWE值呈负相关（r = -0.710，P < 0.001）。
这些结果表明SWE是一种敏感的非侵入性方法，可实时定量评估牙龈弹性的变化。
