摘要
目的观察富血小板纤维蛋白(PRF)用于阻生齿拔除的临床疗效。方法将下颌近中水平阻生齿60颗随机分为研究组与对照组各30颗,研究组术后牙槽窝放置PRF,对照组牙槽窝常规处理。比较2组术后并发症的发生情况及术后1、3、6个月牙槽骨的骨密度。结果研究组术后并发症发生率低于对照组,术后第1、3个月的牙槽骨新生骨骨密度与同期对照组新生骨骨密度相比均明显增高,差异均有统计学意义(P <0. 05),但术后第6个月2组的牙槽骨骨密度比较差异无统计学意义(P> 0. 05)。结论 PRF可减轻阻生齿拔除术后的并发症,并促进牙槽窝新骨形成,但不能增加骨组织的密度。
Objective To observe the clinical efficacy of platelet-rich fibrin( PRF) for the extraction of impacted teeth. Methods 60 teeth of the mandibular near-middle level impacted teeth were randomly divided into study group and control group,each of 30 cases. In study group,PRF was placed in the alveolar fossa,and control group was routinely treated. The incidence of postoperative complications and the bone mineral density of alveolar bone at 1,3,and 6 months after surgery were compared in two groups. Results The incidence of postoperative complications in study group was lower than control group,the bone mineral density of the alveolar bone in the first and third months after operation was significantly higher than control group,the difference was statistically significant( P < 0. 05),but there was no significant difference in alveolar bone mineral density between two groups( P > 0. 05). Conclusion PRF can ease the postoperative symptom of impacted tooth,and promote the formation of new bone in the distal second molar,but can not increase the density of bone tissue.
