The present investigation aimed to evaluate root coverage (RC) with periosteum eversion technique (PET) using periosteum as a graft and coronally advanced flap (CAF) with platelet-rich fibrin (PRF) membrane as a graft in the treatment of isolated Miller's class I and II gingival recession defects.
Thirty sites in 15 participants with Miller's Class I or II gingival recession were randomly treated either with PET using periosteum as graft and CAF + PRF as graft. In a split mouth design, the parameters such as recession depth, recession width at cementoenamel junction, probing depth, periodontal attachment level (PAL), and keratinized gingival width were assessed at baseline, 3 months, and 6 months postoperative follow-up with William's graduated probe and Vernier caliper.
Both the treatment modalities yielded statistically nonsignificant desirable treatment outcomes at both postoperative levels in terms of all the parameters The mean RC with probe method and Vernier method in CAF + PRF was 75.01% and 86.86%, respectively, and PET showed a mean RC of 61.112% and 83.971%, respectively, at 6-month interval period which showed a nonstatistically significant difference.
Both the treatment modalities, i.e., CAF + PRF and PET are essentially and equally effective in the treatment of Miller's Class I or II gingival recession defects.
本研究旨在评估采用骨膜翻转技术(PET)以骨膜为移植材料,以及采用带富血小板纤维蛋白(PRF)膜的冠向推进瓣(CAF)作为移植材料治疗孤立性米勒I类和II类牙龈退缩缺损时的牙根覆盖情况(RC)。
15名患有米勒I类或II类牙龈退缩的受试者的30个部位,随机采用以骨膜为移植材料的PET或CAF + PRF作为移植材料进行治疗。采用双切口设计,在基线、术后3个月和6个月随访时,使用威廉斯刻度探针和游标卡尺评估诸如退缩深度、釉牙骨质界处的退缩宽度、探诊深度、牙周附着水平(PAL)和角化龈宽度等参数。
就所有参数而言,两种治疗方式在两个术后阶段均产生了统计学上无显著差异的理想治疗效果。在6个月的间隔期,CAF + PRF采用探针法和游标卡尺法测得的平均牙根覆盖率分别为75.01%和86.86%,PET的平均牙根覆盖率分别为61.112%和83.971%,差异无统计学意义。
CAF + PRF和PET这两种治疗方式在治疗米勒I类或II类牙龈退缩缺损方面基本等效且同样有效。
