RESUMO

Lateral cephalometric radiographies have been commonly used by health professionals. To obtain them, the patient s head should be adequately positioned, being the Frankfort horizontal plane (FHP) the most recommended and used by the Radiologists. Incorrect cephalic positioning is one of the factors that lead professionals, especially orthodontists, to reject such radiographies. This incorrect positioning might be related to the patient s head movement and/or errors made by the operator. Osseous FHP might not have a perfect correspondence with cutaneous FHP, leading professionals to judge the xray as unsatisfactory. Therefore, the aim of this study was to analyze the relationship between osseous FHP and cutaneous FHP (a line linking the superioredge of tragus to the inferioredge of eyeorbit), considering the cephalic variation among the different races, using the lateral cephalometric approach. The sample consisted of 27 individuals: 9 negroids, 9 caucasians, and 9 asians, being also assigned to two groups according to their facial pattern: 14 brachyfacial and 13 dolichofacial. Photographs were used to obtain cutaneous PHF. The lateralcephalometric Broadbent (1931) radiographic method was used in order to obtain the lateral photographs, using the relation of the cutaneous FHP and the horizontal plane. ...
