BACKGROUND/PURPOSE: This study was conducted to evaluate the influence of mucogingival parameters, including keratinized mucosa (KM) and attached gingiva (AG), on the outcome of non-surgical periodontal therapy (NSPT).
A total of 204 non-smoking patients with generalized chronic periodontitis who received NSPT between 2012 and 2014 were included. The Mantel-Haenszel chi-square test was used to assess the associations between initial mucogingival parameters and initial clinical parameters on the buccal aspect, and the associations between initial mucogingival parameters and outcome clinical parameters on the buccal aspect of the sites with severe periodontal destruction. The generalized liner model was used to evaluate the contribution of initial clinical parameters to the outcome of NSPT.
KM ≥ 3 mm was associated with greater probing pocket depth (PD), less gingival recession (REC), and less clinical attachment level (CAL), and AG < 1 mm was associated with greater PD, REC, and CAL before NSPT. At the sites with severe periodontal destruction, KM ≥ 3 mm was associated with greater PD reduction (0.25 ± 0.08 mm) and CAL gain (0.25 ± 0.09 mm), and AG < 1 mm was associated with greater CAL gain (0.15 ± 0.08 mm) after NSPT. Initial PD ≥ 7 mm and non-molar teeth showed greater contribution to the outcome of NSPT.
Less AG (<1 mm) was associated with greater periodontal destruction at baseline. At the sites with severe periodontal destruction, greater KM (≥3 mm) and less AG (<1 mm) resulted in better outcomes of NSPT.
背景/目的：本研究旨在评估黏-牙槽参数（包括角化黏膜（KM）和附着龈（AG））对非手术牙周治疗（NSPT）效果的影响。
共纳入 204 名 2012 年至 2014 年间接受 NSPT 的非吸烟、广泛性慢性牙周炎患者。采用 Mantel-Haenszel χ2 检验评估初始黏-牙槽参数与颊侧初始临床参数以及初始黏-牙槽参数与颊侧严重牙周破坏位点的治疗后临床参数之间的相关性。采用广义线性模型评估初始临床参数对 NSPT 效果的贡献。
KM≥3mm 与较大的探诊深度（PD）、较小的牙龈退缩（REC）和较小的临床附着丧失（CAL）相关，AG＜1mm 与 NSPT 前较大的 PD、REC 和 CAL 相关。在严重牙周破坏的位点上，KM≥3mm 与较大的 PD 减少（0.25±0.08mm）和 CAL 增加（0.25±0.09mm）相关，AG＜1mm 与 NSPT 后较大的 CAL 增加（0.15±0.08mm）相关。初始 PD≥7mm 和非磨牙对 NSPT 效果的贡献更大。
AG 较少（＜1mm）与基线时更大的牙周破坏相关。在严重牙周破坏的位点上，较大的 KM（≥3mm）和较小的 AG（＜1mm）导致 NSPT 效果更好。
