Abstract

To determine reference values of orofacial myofunctional condition and orofacial forces in healthy young and adults. Fifty young and adults were selected from a total of 316 voluntaries. Participants were assessed with the Orofacial Myofunctional Evaluation with Scores (OMES) for the investigation of orofacial myofunctional condition. The maximum forces of bite, cheeks, tongue (anterior and posterior regions), and lips were assessed with an electronic dynamometer (values expressed in Newtons). Force values were obtained by average of three repeated measurement. The technical error of measurements was calculated for all variables. There were no differences in orofacial myofunctional condition between men and women. Men presented higher values of orofacial forces compared to women. The normal values of orofacial myofunctional condition and orofacial forces were determined in healthy and adults Brazilian men and women. The values obtained in this study from healthy Brazilian may help in the diagnosis of alterations in orofacial motor function and contribute for their therapeutic management.

Highlights

Face and tongue muscles are crucial for the performance of orofacial functions including mastication, speech, deglutition, and facial expressiveness[1], which are relevant for one’s health and quality of life
The Technical Error of Measurements (TEM) was estimated for all variables of study by Dahlberg’s formula [∑(D2) / 2 x n]0-5, where D stands for the difference between two repeated measures and n refers to the sample size
The reliability of the orofacial forces was analyzed by the interclass correlation coefficient (ICC), based on measurements performed on twelve voluntaries, by two independent raters (ICC Inter- raters), and two repeated measurements by the same rater (ICC Intra-rater)

Summary

Introduction

Face and tongue muscles are crucial for the performance of orofacial functions including mastication, speech, deglutition, and facial expressiveness[1], which are relevant for one’s health and quality of life. When the performance of orofacial muscles is impaired, problems may occur in mastication and in the manipulation and propulsion of the food bolus during deglutition, for example. Tasks that demand maximal performance, such as those used in the assessment of maximal muscle force, may reveal possible neuromuscular impairments. They can serve as a diagnostic tool and provide information for therapeutic planning[1]
