摘要/Abstract

摘要： 目的: 评价十字形分牙法和T形截冠法拔除下颌中低位阻生牙的疗效。方法: 选择2024年9月—2024年11月亳州市人民医院收治的下颌中低位阻生牙患者81例,按照拔牙方法不同分为对照组（n=40,T形截冠法）和试验组（n=41,十字形分牙法）。比较两组手术时间、术中并发症（焦虑、断根）、术后并发症（疼痛、肿胀、开口受限）、术后1周拔牙创愈合情况,以及术前、术后1周的生活质量[口腔健康影响程度量表14（oral health impact scale 14,OHIP-14）]。结果: 试验组手术时间显著短于对照组,术中并发症总发生率（4.88%）显著低于对照组（20.00%）,术后疼痛及开口受限评分显著低于对照组,术后肿胀程度显著轻于对照组,术后并发症总发生率（4.88%）显著低于对照组（32.43%）,术后1周拔牙创愈合评分显著低于对照组（P<0.05）。术后1周,两组OHIP-14评分降低,且试验组显著低于对照组（P<0.05）。结论: 与T形截冠法相比,十字形分牙法可缩短下颌中低位阻生牙拔除的手术时间,降低术中焦虑、断根及术后疼痛、肿胀、开口受限的发生率,有利于拔牙创愈合。

Abstract: PURPOSE: To evaluation the effect of cruciform tooth division and T-type crown amputation in extraction of mandibular middle and low impacted teeth. METHODS: A total of 81 patients with mandibular middle and low impacted teeth treated in Bozhou People's Hospital from September to November 2024 were selected. According to the different extraction methods,they were divided into the control group(n=40, T-type crown amputation) and experimental group(n=41, cross tooth extraction). The operative time, intraoperative complications(anxiety, broken root), postoperative complications (pain, swelling and restricted mouth opening), healing of tooth extraction socket 1 week after surgery, and quality of life before and 1 week after surgery[oral health impact scale 14(OHIP-14)] were compared between the two groups. RESULTS: The operative time of the experimental group was significantly shorter than that of the control group, the total incidence of intraoperative complications(4.88%) was significantly lower than that of the control group (20.00%), the score of postoperative pain and mouth opening restriction was significantly lower than that of the control group, the degree of postoperative swelling was significantly less than that of the control group, and the total incidence of postoperative complications(4.88%) was significantly lower than that of the control group(32.43%). The healing score of tooth socket 1 week after operation was significantly lower than that of the control group (P<0.05). One week after surgery,the OHIP-14 score of both groups was decreased,and the experimental group was significantly lower than the control group(P<0.05). CONCLUSIONS: Compared with T-type crown amputation, cruciform tooth division can shorten the operation time of mandibular middle and low impacted tooth extraction, reduce the occurrence of intraoperative anxiety, broken root, postoperative pain, swelling and restricted mouth opening, and is conducive to the healing of tooth extraction wound.
