Relationship between headaches and malocclusion

目的：有关头痛与错(牙合)关系的研究较少。在此，我们从1401名在牙科接受治疗的门诊患者中检查了689名在过去一年中经历过头痛的牙科患者。方法：根据前、后牙合异常以及向上和向下异常(正常、深牙合和开牙合)，将患者分为3组(正常、上颌前突和下颌前突)。头痛的诊断是由神经科医生根据HIS标准进行的。结果：在接受调查的1401名受试者中，49.2%的人出现了头痛。其中，单纯偏头痛占30.2%，单纯紧张型头痛占27.6%，混合型或混合型头痛占42.2%。2.在前后畸形分类中，错(牙合)型头痛的发生率依次为下颌前突、上颌前突、正常组。在正常和下颌前突受试者中，偏头痛的发生率高于紧张型头痛。从上下畸形的分类来看，错牙合类型中头痛的发生率最高，依次为外牙合、深牙合、正常组。在正常和开放咬合受试者中，偏头痛的发生率高于紧张型头痛。结论：虽然它们的详细病因尚不清楚，但本研究的发现表明，错牙合可能在偏头痛和紧张型头痛的发病中起作用。

OBJECTIVE : Few studies have investigated the relationship between headaches and malocclusion. Here, we examined 689 dental patients who had experienced headaches within the previous year from among 1401 outpatients who had received treatment at the Department of DentistryMethod : Patients were classified 3 malocclusion groups (normal, maxillary protrusion and mandibular protrusion) based on anterior-posterior abnormalities as well as upward and downward abnormalities (normal, deepbite, and openbite). The diagnosis of headache was performed by a neurologist, according to the criteria HIS.RESULT :I.Headaches were seen in 49.2% of the 1401 subjects surveyed. Among these subjects, those with only migraine accounted for 30.2%, those with only tension-type headaches accounted for 27.6%, and those with mixed-type or miscellaneous headaches accounted for 42.2%.II.In terms of the classification of anterior and posterior abnormalities, the incidence rate of headaches among malocclusion types were most numerous in the order of mandibular protrusion, maxillary protrusion, and normal groups. The incidence of migraine was higher than tension-type headaches in normal and mandibular protrusion subjects. The reverse was obserbed in maxillary protrusion subjects.III.In terms of the classification of upward and downward abnormalities, the incidence rate of headaches among malocclusion types were most numerous in the order of operibite, deepbite, and normal groups. The incidence of migraine was higher than tension-type headaches in normal and openbite subjects. The reverse was obserbed in deepbite subjects.CONCLUSION : Although their detailed aetiology is still unknown, the finding of this study suggest that malocclusion may play a role in the onset of migraine and tension-type headaches.
