摘要:

背景:重组牛碱性成纤维细胞生长因子是一种多效能的细胞因子,具有促进血管生成,创面愈合和组织修复及促进骨再生的能力,并有具有组织相容性好、易操作的特性,在口腔颌面外科领域应用广泛。

目的:将重组牛碱性成纤维细胞生长因子凝胶植入下颌阻生牙拔除后牙槽窝,评价其预防干槽症的效果。

方法:纳入拔除下颌阻生牙的患者160例,随机数字表法均分成2组,试验组在拔除阻生牙后放入重组牛碱性成纤维细胞生长因子,对照组不放任何材料任其自行愈合,拔牙后3 d,5 d和1周门诊复诊观察干槽症的发生情况,比较两组干槽症的发病率。

结果与结论:试验组有1例干槽症发生,发生率为1.25%。对照组有10例干槽症发生,发生率为12.5%。两组干槽症发生率比较差异有显著性意义(P < 0.01)。试验组拔牙后牙槽窝内可见肉芽组织,拔牙窝缩小,充满新生肉芽组织,比对照组早一两天。患者应用重组牛碱性成纤维细胞生长因子凝胶均未发生过敏、组织增生等局部及全身反应。说明下颌阻生牙拔牙后局部应用重组牛碱性成纤维细胞生长因子凝胶对干槽症的发病有预防作用,能加快拔牙创的愈合。

Abstract:

BACKGROUND: Recombinant bovine basic fibroblast growth factor is a manifold effect cytokine which can promote angiogenesis, wound healing, tissue repair and bone regeneration. Recombinant bovine basic fibroblast growth factor with good histocompatibility is easy to operate and has been widely used in oral and maxillary surgery.

OBJECTIVE: To evaluate the effect of recombinant bovine basic fibroblast growth factor against dry socket syndrome after tooth extraction.

METHODS: A total of 160 patients who had been extracted mandibular third molar were selected and randomly divided into two groups. In the experimental group, recombinant bovine basic fibroblast growth factor was put into the sockets after mandibular third molars were extracted, while in the control group, we let the wounds to be healed naturally without any materials. The incidence of dry socket syndrome was observed and compared between two groups at 3 days, 5 days and 1 week after tooth extraction.

RESULTS AND CONCLUSION: One patient had dry socket after operation in the experimental group, and the incidence was 1.25%. In the control group, 10 patients suffered from dry socket, and the incidence was 12.5%. There was a significant difference in the incidence of dry socket between the two groups (P < 0.01). There was visible granulation tissue within the tooth socket after tooth extraction in the experimental group, and extraction sockets narrowed and were filled with granulation tissues, which was 1-2 days earlier than the control group. No allergies, tissue hyperplasia and other local and systemic reactions occurred in patients receiving implantation of  recombinant bovine basic fibroblast growth factor gel. These findings indicate that local implantation of recombinant bovine basic fibroblast growth factor gel after mandibular tooth extractions can speed up the healing of dental extraction wounds.
