富血小板纤维蛋白辅助治疗牙龈退缩的临床效果及患者满意度评价

摘要/Abstract

摘要： 目的评价和比较冠向复位瓣术单独或联合应用富血小板纤维蛋白（platelet rich fibrin,PRF）治疗Miller Ⅰ类或Ⅱ类牙龈退缩的临床效果及患者满意度。方法临床上选取Miller Ⅰ类或Ⅱ类牙龈退缩且有意愿进行手术治疗的患者30例，分为试验组（冠向复位瓣术联合PRF）、对照组（冠向复位瓣术）。在术前、术后3个月、术后6个月记录牙周探诊深度、角化龈宽度、牙龈退缩深度以及根面覆盖率，分析2组的临床疗效，患者填写满意度调查表，并进行分析。结果试验组和对照组在术后3、6个月检查临床指标牙龈退缩深度、角化龈宽度较术前明显好转，差异有统计学意义（P<0.05）；术后3、6个月，试验组和对照组2组间角化龈宽度比较，差异有统计学意义（P<0.05）；术后3、6个月，2组间牙周探诊深度、牙龈退缩深度、根面覆盖率比较均无统计学差异(P>0.05)；术后3、6个月时，2组中的牙周探诊深度与术前相比，差异无统计学意义(P>0.05)；试验组患者的满意度显著高于对照组，差异有统计学意义(P<0.05)。结论本研究结果进一步证实了这两种方法对MillerⅠ、Ⅱ类牙龈退缩的治疗均有效，辅助应用PRF可增加术后角化龈宽度，并提高患者满意度。

Abstract: Objective To evaluate and compare the clinical effects and patients′ satisfaction with treatment of Miller Ⅰ or Ⅱ gingival recession by coronally advanced flap alone or with platelet rich fibrin(PRF). Methods Thirty patients with Miller Ⅰ or Ⅱ gingival recession and willing to undergo surgical treatment were selected and divided into experimental group (coronally advanced flap combined with PRF) and control group (coronally advanced flap). Periodontal probing depth, keratinized gingiva width, gingival recession depth and root coverage were recorded before surgery, 3 months and 6 months after surgery. The clinical efficacy of the two groups was analyzed, and the satisfaction questionnaire was filled out and analyzed. Results The clinical indexes of gingival recession depth and keratinized gingiva width at 3 and 6 months after surgery were significantly improved compared with those before operation in the experimental group and the control group, and the differences were statistically significant (P<0.05). The width of keratinized gingiva between the two groups was statistically different at 3 and 6 months after surgery (P<0.05). There were no statistically significant differences in the periodontal probing depth, gingival recession depth, and root coverage between the two groups at 3 months and 6 months after surgery (P>0.05). There was no significant difference in the periodontal probing depth between the two groups at 3 months and 6 months after surgery compared with that before the operation (P>0.05). The satisfaction of patients in the experimental group was significantly higher than that in the control group, and the difference was statistically significant (P<0.05). Conclusion The results of this study further confirm that these two methods are effective for the treatment of Miller Ⅰand Ⅱ gingival recession, and the adjuvant application of PRF can increase the width of postoperative keratinized gingiva and improve patients′ satisfaction.
