Periodontitis is bacteria-related chronic inflammatory condition characterized by pocket formation, loss of clinical attachment, gingival recession, mobility, and eventual loss of teeth. The purpose of this study was to clinically evaluate the need for elimination of the pocket epithelium during mucoperiosteal flap surgery aimed at reattachment or re-adaptation.
A split mouth design was done to compare modified Widman flap (MWF) with removal of the pocket epithelium and crevicular mucoperiosteal flap (CMF) without removing the pocket epithelium. The following measurements were taken after 1 month of completion of nonsurgical phase gingival index (Loe and Silness), plaque index (Silness and Loe), mobility, furcation involvement, level of attachment, pocket depth, gingival recession, gingival contour index, and dentinal hypersensitivity (ice stick test). In addition to these measurements, which were taken immediately prior to the surgery (baseline), 1- and 3-month and 6 months postsurgical measurements were also recorded.
The results of this study showed a greater reduction of mean probing depth in the test group (MWF). The control group (CMF) showed greater mean gingival recession compared to the test group throughout the study period. The test group showed more gain in the clinical attachment levels compared with the control group. The difference between the two groups was statistically significant (P < 0.001).
The results of this study demonstrate that MWF surgery was more effective in reducing mean probing depth, showed greater gain in clinical attachment, and demonstrated less gingival recession.
牙周炎是一种与细菌相关的慢性炎症性疾病,其特征为牙周袋形成、临床附着丧失、牙龈退缩、牙齿松动,最终导致牙齿缺失。本研究的目的是在旨在实现再附着或重新适应的黏骨膜瓣手术中,临床评估消除牙周袋上皮的必要性。
采用双侧对照设计,比较去除牙周袋上皮的改良Widman瓣(MWF)与未去除牙周袋上皮的龈沟黏骨膜瓣(CMF)。在非手术阶段完成1个月后,进行以下测量:牙龈指数(Loe和Silness)、菌斑指数(Silness和Loe)、牙齿松动度、根分叉病变、附着水平、牙周袋深度、牙龈退缩、牙龈外形指数和牙本质过敏症(冰棒试验)。除了在手术前立即进行的这些测量(基线)外,还记录了术后1个月、3个月和6个月的测量结果。
本研究结果显示,试验组(MWF)的平均探诊深度降低幅度更大。在整个研究期间,对照组(CMF)的平均牙龈退缩程度比试验组更大。与对照组相比,试验组的临床附着水平增加更多。两组之间的差异具有统计学意义(P < 0.001)。
本研究结果表明,MWF手术在降低平均探诊深度方面更有效,临床附着增加更多,牙龈退缩更少。
