The aim of this study is to assess the relationship between masticatory and salivary function and anthropometric and nutritional assessments of 200 pre pubertal children of both genders. The chewing function will be assessed by means of masticatory performance evaluation. The masticatory performance will be determined by the individual capacity of the fragmentation of a test food (Optocal plus) and sieving technique. Salivary flow rate will be determined by collecting saliva by mechanical stimulation (chewing Parafilm®) and without stimulation, and then pH and the concentrations of total protein, amylase, calcium, urea and lipids will be determined by spectrophotometry. In addition, the limiar will be evaluated to detect the four primary tastes (sweet, salty, sour and bitter) in three different concentrations. These variables of the masticatory function will be associated with anthropometric (body mass index and arm and abdominal circumferences) and food intake by 24-hour recall and the calculation of estimated dietary intake by means of a software. The description and the relationship between the variables under study will be evaluated using descriptive statistics, Komolgorov-Smirnov normality test, correlation tests (Pearson or Spearman) and tests of means ("t" Student / Mann-Whitney test). Multiple linear regression models with stepwise backward elimination will verify the relationship between anthropometric measurements (as the dependent variables) and the flow, composition and pH of saliva, masticatory performance, sensory analysis and food intake, controlling for gender and age (± = 0.05).
