“…Comparisons with other studies are tricky, since values of masticatory performance may be confounded by the use of different methodologies. Nevertheless, the results of bite force were similar to those of other studies in pre-school children, 14,15 despite the different devices used.…”

“…About thirty children were selected, but only 15 cooperated and performed the two tests properly, despite the training before the experiments. The sample size was determined taking into account the correlation coefficients found in the literature 5,14,15,19 for a power test of 0.8, being 15 subjects a sufficient number.…”

“…13 Other factors, such as state of dentition, instrumentation design and transducer position related to dental arch, 15,25 malocclusions, signs and symptoms of temporomandibular disorders; size, composition and mechanical advantage of jaw-closing muscles, may influence the values found for bite force. 1,15,25 Thus, the subjects' sensory feedback may limit willingness to exert the maximum effort. 6 The primary occlusion directly influences the development of the permanent dentition 16 , and conditions that are known to interfere with growth and development should be considered.…”

The aim of this study was to evaluate the relationship between masticatory performance and maximum bite force in the primary dentition. The sample comprised 15 children of both genders, aged 3 to 5.5 years, with good systemic and oral health, presence of all primary teeth without large caries, no structural anomalies, without severe malocclusion, and no history of orthodontic treatment. They chewed one standardized silicone tablet for 20 strokes and the median areas of the chewed particles were measured by an optical digital system. Enhanced performance was measured by a decrease in the chewed particle areas and an increase in the amount of chewed particles. The bite force was determined using a transmitter pressurized tube connected to an analog/digital electronic circuit. Weight, height and body mass index (kg/m 2 ) were determined. The data were analyzed by descriptive statistics and Pearson or Spearman's correlations, after assessment of the normality of the distribution by Shapiro-Wilks' W-test. There was no correlation between bite force and particle area and amount (p > 0.05), neither were the body variables correlated with the masticatory variables (p > 0.05). It was concluded that the bite force was not a primary determinant of masticatory performance, and both variables were not dependent on body variables in the studied sample.

A amostra consistiu de 15 crianças de 3 a 5,5 anos de idade, de ambos os gêneros, apresentando boa saúde bucal e sistêmica, com a presença de todos os dentes decíduos, sem cáries extensas, sem anomalias estruturais, sem maloclusão severa e ausência de tratamento ortodôntico. Um tablete de silicone foi mastigado durante 20 ciclos e as áreas medianas das partículas foram mensuradas por um sistema óptico digital. A performance mastigatória foi considerada melhor quanto menor o tamanho das partículas mastigadas e quanto maior o número das mesmas. Para a força de mordida utilizou-se um tubo transmissor pressurizado, conectado a circuito eletrônico analógico/digital. O peso, a altura e o índice de massa corporal (kg/m 2 ) foram determinados. Os dados foram analisados pela estatística descritiva e correlacionados pelo coeficiente de Pearson ou Spearman, após a avaliação da normalidade da distribuição pelo teste de Shapiro-Wilks. Não houve correlação significativa entre a força de mordida e as áreas e o número das partículas (p > 0,05), assim como as variáveis corporais não se correlacionaram com as variáveis mastigatórias (p > 0,05). Concluiu-se que a força de mordida não foi o principal determinante da performance mastigatória na amostra avaliada, e ambas não foram dependentes das variáveis corporais.

Development of the masticatory system is influenced by functional needs. Furthermore, masticatory exercise can improve masticatory function. The aim of this study was to evaluate the potential effect of the gum chewing exercise on the maximum bite force (MBF) in adult subjects with different facial morphologies. MBF was measured by a portable occlusal force gauge and lateral cephalogram was used for evaluation of craniofacial morphology in 19 individuals (7 males and 12 females) with a mean age of 25.4 years (SD ± 4.3). The volunteers underwent gum chewing exercise for 5 min twice a day for 4 weeks. MBF was measured before (T1) and after the 4‐week exercise (T2). The facial morphology of the subjects was classified into the brachy (n = 7), mesio (n = 7), and dolicho (n = 5) facial types. In all three groups, exercise was associated with a significant increase in MBF, though the percent increase was highest in the dolicho facial type. We conclude that gum chewing exercise can improve masticatory performance, especially in individuals with dolicho facial morphology.

ObjectivesThis cross‐sectional study aimed to investigate the age‐related development of five major oral functions—tongue pressure, lip pressure, masticatory efficiency, bite force, and occlusal contact area—in subjects aged 5–20 years.Material and MethodsNinety‐two subjects were divided into four age groups: 5–8, 9–12, 13–16, and 17–20 years. Oral functions were evaluated using standardized methods, including Chew Check Gum for assessing masticatory efficiency, Dental Prescale II for measuring occlusal force and contact area, JMS tongue pressure measuring device for evaluating tongue pressure, and Ripple‐Kun for measuring lip pressure.ResultsOcclusal contact area, maximum bite force, tongue pressure, and masticatory efficiency gradually increased with age, whereas lip pressure remained stable. The occlusal contact area temporarily decreased between 5 and 12 years of age, likely due to the replacement of erupting lateral teeth. Some differences were observed between males and females; however, overall trends in oral function parameters were similar. Spearman's rank correlation analyses revealed significant positive correlations between age and occlusal contact area, bite force, tongue pressure, and masticatory efficiency.ConclusionsOral function parameters exhibited different age‐related development patterns. Occlusal contact area, maximum bite force, tongue pressure, and masticatory efficiency gradually increased with age. Interestingly, the occlusal contact area tended to reduce temporarily between 5 and 12 years of age due to the replacement of erupting lateral teeth. Conversely, lip pressure was almost stable during this period. Our findings provide valuable insights into the developmental patterns of oral functions during the growing years.
