Abstract
The purpose of this study was to investigate the relationship between orthodontic treatment and temporomandibular dysfunction (TMD). A questionnaire on TMD was carried out with ninety-five patients (22 males and 73 females) who finished orthodontic treatment (multi bracket, chin cap and FKO).
The results were as follows;
1. Twenty-five percent of the orthodontic patients experienced TMD. There was no significant difference in the prevalence of TMD irrespective of the orthodontic method. The prevalence of temporomandibular joint sounds amounted to twenty percent, that of limitation and pain amounted to twelve percent respectively.
2. Sixty percent of the TMD symptoms which occurred after orthodontic treatment disappeared naturally. Of patients who answered the question saying they felt the symptoms of TMD up to then, only twenty-two percent was confirmed through clinical examination.
