To determine the efficacy of latelet-rich fibrin (PRF) and Amniotic membrane (AM) along with the coronally advanced flap (CAF) technique in treating Miller's class I gingival recession (GR) defects.
A total of 32 sites with Miller's class I GR defects were distributed into Group A (CAF + PRF, n = 16) and Group B (CAF + AM, n = 16). Clinical parameters like gingival index (GI), plaque index (PI), gingival bleeding index (GBI), gingival sulcus depth (GSD), relative attachment level (RAL), and gingival marginal level (GML) were measured at baseline and at 3, 6 and 9 months after surgical intervention.
PRF and AM with CAF were effective treatment modalities for treating Miller's class I GR defects, with an average root coverage value of 2.00 ± 0.75 mm in Group A and 1.5 ± 0.3 mm in Group B. Complete coverage (100 %) was obtained in 57 % sites of group A and 49 % sites of group B. At the 9-month follow-up, there was a significant increase in relative attachment levels in both groups when compared to baseline.
In the present study it was observed that there was a clinically and statistically significant improvement in root coverage with both groups. PRF-treated sites showed > 50 % complete coverage and hence were superior. AM showed comparable results to PRF and could be used as an alternative.
确定富血小板纤维蛋白（PRF）和羊膜（AM）联合冠向推进瓣（CAF）技术治疗米勒I类牙龈退缩（GR）缺损的疗效。
将32个患有米勒I类GR缺损的部位分为A组（CAF + PRF，n = 16）和B组（CAF + AM，n = 16）。在基线以及手术干预后3、6和9个月测量临床参数，如牙龈指数（GI）、菌斑指数（PI）、牙龈出血指数（GBI）、牙龈沟深度（GSD）、相对附着水平（RAL）和牙龈边缘水平（GML）。
PRF和AM联合CAF是治疗米勒I类GR缺损的有效治疗方式，A组平均牙根覆盖值为2.00±0.75mm，B组为1.5±0.3mm。A组57%的部位和B组49%的部位实现了完全覆盖（100%）。在9个月的随访中，与基线相比，两组的相对附着水平均有显著增加。
在本研究中观察到，两组的牙根覆盖在临床和统计学上均有显著改善。PRF治疗的部位显示>50%的完全覆盖，因此更具优势。AM显示出与PRF相当的结果，可作为替代方案使用。
