The aim of this study was to determine whether the addition of an autologous platelet rich fibrin (PRF) membrane to a coronally advanced flap (CAF) would improve the clinical outcome in terms of root coverage, in the treatment of isolated gingival recession.
Systemically healthy 20 subjects each with single Miller's class I or II buccal recession defect were randomly assigned to control (CAF) or test (CAF + PRF) group. Clinical outcome was determined by measuring the following clinical parameters such as recession depth (RD), recession width (RW), probing depth (PD), clinical attachment level (CAL), width of keratinized tissue (WKT), gingival thickness (GTH), plaque index (PI), and gingival index (GI) at baseline, 3(rd), and 6(th) month postsurgery.
The root coverage was 65.00 ± 44.47% in the control group and 74.16 ± 28.98% in the test group at 6(th) month, with no statistically significant difference between them. Similarly, CAL, PD, and WKT between the groups were not statistically significant. Conversely, there was statistically significant increase in GTH in the test group.
CAF is a predictable treatment for isolated Miller's class I and II recession defects. The addition of PRF to CAF provided no added advantage in terms of root coverage except for an increase in GTH.
本研究旨在确定在治疗孤立性牙龈退缩时，在冠向复位瓣（CAF）上添加自体富血小板纤维蛋白（PRF）膜是否会在牙根覆盖方面改善临床效果。
选取20名全身健康、患有单个米勒I类或II类颊侧退缩缺损的受试者，随机分为对照组（CAF）和试验组（CAF + PRF）。通过在基线、术后第3个月和第6个月测量以下临床参数来确定临床效果，这些参数包括退缩深度（RD）、退缩宽度（RW）、探诊深度（PD）、临床附着水平（CAL）、角化组织宽度（WKT）、牙龈厚度（GTH）、菌斑指数（PI）和牙龈指数（GI）。
第6个月时，对照组的牙根覆盖率为65.00±44.47%，试验组为74.16±28.98%，两组之间无统计学显著差异。同样，两组之间的CAL、PD和WKT也无统计学显著差异。相反，试验组的GTH有统计学显著增加。
CAF是治疗孤立性米勒I类和II类退缩缺损的可预测治疗方法。在CAF上添加PRF除了增加GTH外，在牙根覆盖方面没有额外优势。
