Abstract

Maximum bite force determination is a subjective variable of great importance for the establishment of the correct treatment plan and prognosis in oral rehabilitations. The instruments used for this measurement are not feasible for office routine, due to the high financial cost. On the other hand, manual dynamometers for manual force measurement can offer an alternative to overall strength and presents a low cost. The aims of this study, is to estimate the correlation between the mean hand grip strength and maximum bite force of non-edentulous young individuals (aged 18 to 25 years - Group I); edentulous and non-edentulous adults (aged 40-59 years - Group II); female users of bimaxillary total prostheses (Group III); in addition to compare the average grip strength and masticatory strength among the different groups. After agree with the free and informed consent form, they will be submitted to the manual gripping force measurement test with the aid of the digital electronic device in the dominant hand, a total of three measurements, of which the average will be calculated. Subsequently, through a digital gnatodynamometer, the maximum bite force in the molar region will be measured, considering the average of three measurements on each side. The Pearson Correlation Coefficient (r) and Multivariate Analysis of Variance (MANOVA) tests will be applied, with a significance level of 5%. (AU)
