Association between perioral muscle pressure and masticatory performance

Abstract

The aim of this study was to determine the association between strength of the perioral muscles and masticatory performance. Subjects were 56 healthy adults (30 men and 26 women; mean age of 24·9 years) with normal occlusion. Perioral muscle pressure was measured using JMS tongue pressure measurement device, and maximum tongue pressure and cheek pressure on the habitual chewing side (H) and non-habitual side (non-H) were measured. The masticatory performance was evaluated using gummy jelly, and the amount of glucose extracted was measured after chewing under condition H or non-H. The association between sex and maximum tongue pressure was analysed using Student's t-test. Cheek pressure and the amount of the glucose extracted between condition H and non-H or between men and women were analysed by two-way repeated-measures anova. In addition, the correlations between maximum tongue pressure and cheek pressure on condition H, maximum tongue pressure and the amount of glucose extracted under condition H, and cheek pressure and the amount of glucose extracted under condition H were analysed using Pearson's correlation coefficients for men and women. The maximum tongue pressure, cheek pressure and the amount of glucose extracted were higher in men than in women. The amount of glucose extracted was higher under condition H than under condition non-H, but no significant difference in chewing side was observed in cheek pressure between men and women. Additionally, positive correlations were shown between maximum tongue pressure, habitual-side cheek pressure and the amount of glucose extracted on men and women. In conclusion, the association between higher perioral muscle pressure and better masticatory performance was shown.

Comparison of masticatory performance and tongue pressure between children and young adults

“…In the recent studies, tongue pressure and masticatory performance were positively correlated in a sample of young adults (Takahashi et al, 2013); additionally, significant differences in maximum tongue pressure were found between males and females in young adults (Takahashi et al, 2013; Vanderwegen, Guns, Van Nuffelen, Elen, & De Bodt, 2013). The findings were consistent with their results.…”

“…Subjects were asked to place a balloon on the anterior part of their palate and to close their lips, biting a hard ring with the upper and lower incisors. Then, the subjects were asked to raise their tongues and compress the balloon onto the palate with maximal voluntary muscular effort for approximately 7 s. The pressure was measured (in kilopascals) using a digital voltmeter attached to the tongue pressure manometer (Takahashi et al, 2013). …”

“…In humans, after 2–4 years of age, the tongue is used during mastication because the mature swallowing pattern prevails over the infantile swallowing pattern (Peng, Jost‐Brinkmann, Yoshida, Chou, & Lin, 2004). There have been a number of reports concerning the relationship between tongue pressure and chewing ability in young adults (Takahashi, Koide, Arakawa, & Mizuhashi, 2013; Yamada, Kanazawa, Komagamine, & Minakuchi, 2015). Additionally, studies on the relationship between chewing ability and indices of physical constitution, such as body mass index (BMI) and body weight in children with primary dentition, were also reported (Consolacao Soares et al, 2017; Soares et al, 2017).…”

Eficiência mastigatória em crianças respiradoras bucais com e sem alterações na oclusão

“…Provavelmente, se houvesse maior número de sujeitos e em outras fases da dentição, os resultados seriam diferentes. Uma possível explicação para os achados deste estudo, é que alguns fatores são determinantes na performance mastigatória, tais como o número de contatos oclusais, a excursão lateral durante a mastigação, a força de mordida 11,12,25 e, de forma geral, maior força da musculatura perioral 22 .…”
