The purpose of this study was to determine the tongue rest position in subjects with dental normal occlusion and nasal breath, using lateral cephalometric radiographs taken after the ingestion of barium sulphate to evidenciate the contours of the tongue. The study sample was composed by 66 radiographs of white subjects, 26 male and 40 female, aged between 12 and 21 years, from schools in the region of the Great Paulista ABC. The criteria used for diagnosing normal occlusion was the Six keys to normal occlusion (Andrews, 1972) ; at least four out of the six keys should be present, necessarily the first one, which is the inter-arch relation. To take the X-rays, the patient was positioned in the natural head position, and they were taken immediately after the swallowing of barium sulphate. Posteriorly the cephalometric tracings were done and the following measurements were obtained: tongue length, tongue height, distance from the medium area of tongue dorsum to the hard palate, distance between tongue apex and incisal face of lower incisor. The results indicate that there is not a unique pattern for the tongue rest position in oral cavity, therefore presenting various possibilities. Convergence existed only in the fact that all of them touched the soft palate. There was no statistical significant relationship between the tongue rest position and the facial biotypes or the gender.
