The aim of this study was to compare the effectiveness of root coverage through vestibular incision subperiosteal tunnel access (VISTA) technique using platelet rich fibrin (PRF) or subepithelial connective tissue graft (SCTG) in multiple gingival recessions.
A total of 20 patients with multiple gingival recessions were included, and 10 subjects were randomly allocated to test group (VISTA with PRF) and 10 patients to control group (VISTA with SCTG). Clinical parameters were recorded at baseline, 3 months, and 6 months. Patient's response toward the treatment was also assessed by questionnaire.
All the clinical parameters in the study have showed better results in test group when compared to control group after a follow up period of 6 months with statistical significance.
The results of the present study suggested that multiple gingival recessions can be successfully treated with both procedures, but better root coverage and a greater increase in keratinized tissue were achieved with the VISTA technique with SCTG. All the patients in both groups felt it was worth undergoing the treatment.
本研究的目的是比较使用富血小板纤维蛋白（PRF）或上皮下结缔组织移植（SCTG）的前庭切口骨膜下隧道入路（VISTA）技术在多处牙龈退缩中进行根面覆盖的有效性。
共纳入20例多处牙龈退缩患者，随机将10例受试者分配至试验组（VISTA联合PRF），10例患者分配至对照组（VISTA联合SCTG）。在基线、3个月和6个月时记录临床参数。还通过问卷调查评估患者对治疗的反应。
经过6个月的随访期，研究中的所有临床参数在试验组中与对照组相比均显示出更好的结果，具有统计学意义。
本研究结果表明，两种方法均可成功治疗多处牙龈退缩，但VISTA联合SCTG技术实现了更好的根面覆盖和角化组织的更大增加。两组所有患者均认为接受该治疗是值得的。
