口腔齿槽冰帽在下颌阻生智齿拔除术后的疗效评价

Efficacy of Cold Alveolar Gum for Postoperative Reaction after Extraction of Impacted Mandibular Third Molar Surgery

目的:探讨齿槽医用冰帽应用于下颌阻生智齿拔除术后的临床疗效。方法:选取60例下颌阻生智齿患者,随机分为实验组与对照组,术前测量张口度、眼外眦至同侧耳屏中点距离、口角至同侧耳屏中点距离、颏前点至同侧耳根距离,手术采用切开、翻瓣、去骨及分冠手术步骤。术后实验组术区齿槽医用冰帽咬敷,对照组纱布压迫止血,冰袋外敷。术后48h再次测量以上各面部标记点间距离并记录术后疼痛VAS评分,对比齿槽医用冰帽和冰袋的临床效果。结果:两组患者在术后疼痛、面部肿胀方面有统计学差异(P<0.05),在张口度方面无统计学差异(P>0.05)。结论:齿槽医用冰帽对下颌阻生智齿术后反应有疗效,优于面部冰敷。

Objective:To evaluate the efficacy of cold alveolar gum in the postoperative response of impacted mandibular third molar surgery.Methods:A total of 60 patients were randomly allocated to two groups:cold alveolar gum and ice bag.The patients were measured using a plastic flexible ruler and an opening degree measure placed from the tragus to the lateral angle of eye,the tragus to the angle of mouth,the ear root to the pogonion and the mouth-opening preoperatively and postoperatively,while the postoperative pain was evaluated by visual analog scale(VAS)at the 48 hours after surgery.The clinical effects of cold alveolar gum and ice bag were compared.Results:The significant differences were found in the postoperative pain and the facial swelling between two groups(P<0.05).However,no differences were found in the mouth opening.Conclusion:This study illustrates the efficacy of cold alveolar gum that actually ameliorated the postoperative reaction in the extraction of the impacted mandibular third molar and was superior to the ice bag.
