The aim of this study was to identify the indications for the removal of mesio-angular mandibular third molars based on age and dental health as measured by the DMFT (decayed, missing, and filled teeth) score, and to find out if early intervention should be considered. We studied 319 patients who had 431 mesio-angular mandibular third molars removed. Variables recorded were age, primary indication for removal, and the DMFT score. Indications for removal included distal cervical caries (DCC) in the mandibular second molar (n=180, 44%), pericoronitis (n=131, 32%), and caries and related disease (n=62, 15%). The frequency of distal cervical caries (DCC) in the mandibular second molar increased linearly as patients became older and was the most common reason why mesio-angular third molar teeth were removed. This suggests that patients should be advised of the consequences of retaining thesetypes of third molars, and offered prophylactic removal of asymptomatic teeth.
本研究的目的是根据年龄和通过DMFT（龋失补牙）评分衡量的牙齿健康状况，确定拔除近中阻生下颌第三磨牙的指征，并探讨是否应考虑早期干预。我们研究了319例拔除431颗近中阻生下颌第三磨牙的患者。记录的变量包括年龄、拔除的主要指征和DMFT评分。拔除指征包括下颌第二磨牙远中颈部龋（DCC）（n = 180，44%）、冠周炎（n = 131，32%）以及龋病和相关疾病（n = 62，15%）。随着患者年龄增长，下颌第二磨牙远中颈部龋（DCC）的发生率呈线性增加，这是拔除近中阻生第三磨牙最常见的原因。这表明应告知患者保留这类第三磨牙的后果，并建议对无症状的牙齿进行预防性拔除。
