现代牙科学重点实行预防为主,然而,这一原则还不常应用于第三磨牙的治疗,已知的统计学资料有助于临床医生设计适合这些牙齿的治疗方案。本预测研究可获得外科手术确切的指征,决定手术时间,评定由外科手术所引起的并发症,特别注意针对病人年龄与手术后并发症之间关系的研究。方法:资料来自于9,574名患者,总计外科拔除16,127个下颌第三磨牙,男性占研究人数的42.8%(4,097名),女性占57.2%(5,477),患者按以下年龄分组;24岁以下包括24岁者为组1,25～34岁为2组,35岁和35岁以上为3组,年龄组的研究与 Chal-
Modern dentistry focuses on prevention. However, this principle is not always applied to the treatment of third molar. Known statistical information helps clinicians to design treatments that are appropriate for these teeth. This prediction study will provide precise indications of surgery, determine the timing of surgery, assess the complications caused by surgery, with particular attention to the study of the relationship between patient age and postoperative complications. METHODS: The data were obtained from 9,574 patients with a total surgical exclusion of 16,127 mandibular third molars. Men comprised 42.8% (4,097) of the study population and 57.2% (5,477) of the women. The patients were grouped by age group below 24 years old and included 24 The age group is 1,25 to 34 years old for the 2 groups, 35 years old and 35 years old for more than 3 groups, the age group and Chal-
