RESUMO

The aim of this study was to evaluate the morphological, functional and sensorial characteristics of the stomatognatic system in children, adolescents and adults. To evaluate the morphology, the following variables were considered: muscle thickness using ultrasonography, craniofacial dimensions using lateral cephalograms, dentition phase (mixed and permanent dentition). Signs and symptoms of temporomandibular dysfunction, bite force, electromyography of masseter and anterior temporalis and the influence of additional fluids on the swallowing threshold were evaluated as part of the functional exams. In the sensorial evaluation, the perception of attributes during chewing of natural solid food was assessed by a specific questionnaire. It was observed that the masseter and anterior temporalis thickness was not associated to muscle activity. However, the body variables weight and height and facial morphology as well, influenced the muscle thickness. Signs and symptoms of temporomandibular dysfunction were associated to a ?long face? pattern, although it was not possible to identify any predictive trace of dysfunction. Bite force increased from mixed to permanent dentition and the presence of signs and symptoms, specially those related to muscle tenderness, was correlated to a decrease in the bite force for females in the permanent dentition only. In the mastication experiments, the added fluids influenced the electrical activity and number of chewing cycles and sensorial perception as well specially for dry food. The type of food had a larger effect than the additional fluids
