To examine the association between third molars and orofacial pain. We hypothesized that impacted third molars are a cause of orofacial pain.
Magnetic resonance images of 1808 participants from two population-based cohorts from Northeastern Germany were analysed to define the status of third molars according to the Pell and Gregory classification. A self-reported questionnaire and a clinical dental examination were used to detect chronic and acute complaints of orofacial pain, masticatory muscle pain, migraine and other types of headache. Logistic regression models were used to analyse the associations between third molar status and orofacial pain.
Individuals with impacted third molars in the maxilla had a higher chance of chronic orofacial pain than those with erupted third molars (odds ratio 2.19; 95% CI 1.19-4.02). No such association was detected for third molars in the lower jaw. Third molars were not associated with masticatory muscle pain, migraine or other types of headache.
Impacted maxillary third molars might be a cause of chronic orofacial pain. Thus, physicians should consider the eruption/impaction status of third molars in their decision-making process when treating patients who complain of orofacial pain.
探讨第三磨牙与颌面部疼痛的关系。我们假设阻生的第三磨牙是颌面部疼痛的一个原因。
对来自德国东北部两个基于人群的队列的 1808 名参与者的磁共振图像进行分析，根据 Pell 和 Gregory 分类来确定第三磨牙的状态。使用自我报告的问卷和临床牙科检查来检测颌面部疼痛、咀嚼肌疼痛、偏头痛和其他类型头痛的慢性和急性症状。使用逻辑回归模型分析第三磨牙状态与颌面部疼痛之间的关联。
上颌阻生第三磨牙的个体发生慢性颌面部疼痛的几率高于萌出第三磨牙的个体（比值比 2.19；95%置信区间 1.19-4.02）。下颌第三磨牙与颌面部疼痛之间无关联。第三磨牙与咀嚼肌疼痛、偏头痛或其他类型头痛无关。
上颌阻生第三磨牙可能是慢性颌面部疼痛的一个原因。因此，医生在治疗颌面部疼痛的患者时，应根据第三磨牙的萌出/阻生状态来做出决策。
