The primary goal of this study was to identify and quantify indications for retaining third molars. This retrospective cohort study included 1682 patients (818 male, 864 female; mean age 31 years) who were referred to the University Hospitals Leuven for third molar removal. Eight reasons for retaining the third molars were identified: (1) risk of damaging adjacent structures, (2) compromised health status, (3) adequate space for eruption, (4) third molar serves as abutment tooth, (5) orthodontic reasons, (6) eruption into proper occlusion, (7) symptomless third molars in patients >30 years old, and (8) patient preference. To compare these categories between sex and age groups, a generalized linear model for binary data was fitted with a logit link. A total of 1149 third molars in 548 patients were not extracted. The most frequent reasons for retaining third molar teeth were: eruption into proper occlusion (31.9%), patient preference (31.5%), and symptomless third molars in patients >30 years old (17.5%). Compromised health status and advanced age were often included in the decision regarding whether to retain the third molars. One third of the referred patients had reasons to retain one or more third molars. These findings might facilitate the future development of a consensus statement.
本研究的主要目的是确定并量化保留第三磨牙的适应证。这是一项回顾性队列研究，共纳入了 1682 名患者（818 名男性，864 名女性；平均年龄 31 岁），他们因第三磨牙拔除而被转诊至鲁汶大学医院。确定了保留第三磨牙的 8 个适应证：（1）损伤邻接结构的风险，（2）健康状况受损，（3）萌出空间充足，（4）第三磨牙作为基牙，（5）正畸需要，（6）萌出至正常咬合，（7）30 岁以上无症状的第三磨牙，（8）患者偏好。为了比较这些适应证在性别和年龄组之间的差异，使用二项逻辑斯蒂回归拟合广义线性模型。共有 548 名患者的 1149 颗第三磨牙未被拔除。保留第三磨牙的最常见适应证是：萌出至正常咬合（31.9%）、患者偏好（31.5%）和 30 岁以上无症状的第三磨牙（17.5%）。保留第三磨牙的决策中常考虑健康状况受损和年龄较大等因素。三分之一的转诊患者有保留一颗或多颗第三磨牙的适应证。这些发现可能有助于未来达成共识。
