Determining the Correlation between Chronic Headache and Cervical Lesion of Teeth

Many patients suffer from chronic headache that may last for years and exacerbate recurrently. In cervical lesion malocclusion, premature contacts and occlusal parafunctions may act as an etiological factor and cause chronic headache. To determine the correlation between chronic headaches and cervical lesions of teeth, this study was carried out. In this case-control study, 120 patients were examined (60 case and 60 control). The case group (30 male and 30 female) had chronic headache and Control group (30 male and 30 female) were without any chronic headache. The cervical lesions of the teeth and the occlusion classification were recorded for all the patients. The patients were examined in two age range (22-39 years old and 40-56 years old). Data were analyzed using chi square and Fisher's exact tests. In case and control groups, headache was 60% and 23.3% frequent respectively. The difference was statistically significant (P=0.0001) but there was not any significant difference in headache frequency between males and females (P=0.451). In case group, the prevalence of class I, II and III occlusion was 38/3%, 40% and 21.7% respectively and in control group, the class I, II and II occlusion was 50%, 30%, 20% prevalent respectively. The difference was not significant (P=0.402). In case group, cervical lesion was more prevalent in upper jaw (16.7%) compared with lower jaw (8.3%). The difference was significant (P=0.0001). More cervical lesions were observed in patients with chronic headache.
