An improvement in clinical parameters along with regeneration is the desired outcome of periodontal therapy. The aim of this study was to analyze and contrast the efficaciousness of combined open flap debridement (OFD) and subepithelial connective tissue graft (SECTG) to OFD in the management of periodontal supracrestal defects.
Totally, 20 paired sites exhibiting supracrestal defects were subjected to surgical treatment adopting the split mouth design. The defects were divided randomly for treatment with OFD and SECTG (test) or OFD alone (control). The clinical effectiveness of the two arms of treatment was evaluated at 6 months and 12 months post-operatively by assessing clinical and radiographic parameters. The measurements carried out included probing pocket depth (PPD), relative attachment level (RAL), gingival marginal level, radiographic bone level (BL).
The mean reduction in PPD at 0-12 months was 3.20 ± 0.82 mm and RAL gain of 3.10 ± 1.51 mm was observed, the OFD and SECTG (test) group; corresponding observations for OFD (control) were 2.10 ± 0.63 mm and 1.90 ± 0.57 mm. However, BL changes did not follow the pattern of clinical improvement on the radiographic assessment of either treatment group. Post-operative evaluation was made. Improvement in different clinical parameters was statistically significant (P < 0.01).
Treatment of supracrestal defects with a combination of OFD and SECTG led to significantly better clinical results compared to OFD alone.
临床参数的改善以及组织再生是牙周治疗期望达到的结果。本研究的目的是分析和对比联合开放性翻瓣清创术(OFD)与上皮下结缔组织移植术(SECTG)和单纯OFD治疗牙周袋上缺损的疗效。
采用双侧对照设计,对20对存在牙周袋上缺损的部位进行手术治疗。将缺损随机分为接受OFD联合SECTG治疗(试验组)或仅接受OFD治疗(对照组)。在术后6个月和12个月,通过评估临床和影像学参数来评价两组治疗的临床效果。测量指标包括探诊深度(PPD)、相对附着水平(RAL)、牙龈边缘水平、影像学骨水平(BL)。
在0至12个月期间,OFD联合SECTG(试验组)的PPD平均减少3.20±0.82mm,RAL增加3.10±1.51mm;OFD(对照组)的相应观察值分别为2.10±0.63mm和1.90±0.57mm。然而,在对任一治疗组的影像学评估中,BL变化并未遵循临床改善的模式。进行了术后评估。不同临床参数的改善具有统计学意义(P<0.01)。
与单纯OFD相比,联合OFD和SECTG治疗牙周袋上缺损可带来显著更好的临床效果。
