Objectives Headaches are a common problem among adolescents, and malocclusion is a possible risk factor. The purpose of this study was to investigate the association between malocclusion and headache among Japanese adolescents aged 12–15 years using a population‐based sample. Methods A total of 938 adolescents (94.7% of the target population in Koshu City) participated. A modified version of the Index of Orthodontic Treatment Need ( IOTN ) was used by orthodontists to evaluate occlusal characteristics, and the frequency of headaches (none, rarely, sometimes) was assessed via questionnaire ( N = 938). Ordered logistic regression analyses were used to analyze the association between malocclusion and headache. Results The prevalence of malocclusion diagnosed using the modified version of the IOTN was 44.9%. Multiple ordered logistic regression analyses showed that the odds ratio ( OR ) of having malocclusion for headache was 1.38 (95% confidence interval [ CI ]: 1.06–1.80), after adjustment for demographics, lifestyle, and dental status including orthodontic treatment history and tooth size. Moreover, among occlusal traits, lower crowding was independently associated with headache ( OR : 1.64, 95% CI : 1.07–2.51). Conclusions We found that malocclusion, especially lower crowding, was associated with headache in a population‐based sample of adolescents aged 12–15 years in Japan. Further study is needed to elucidate the mechanisms by which malocclusion affects headache.
