“…Findings agree with studies of Cavalcanti and Bianchini 16 and Duarte 17 , who also found no significant correlation between occlusion and the preferred chewing side. However, is quoted in the literature the influence of occlusal factors in masticatory pattern mainly involving the unilateral occlusal pattern with changes and temporomandibular dysfunction 18,19 .…”

Conflict of interest: non-existent stimulation of supporting structures, such as bones and teeth and for favoring that the harmonious craniofacial growth occurs³ .The chewing pattern can be influenced by several factors, such as occlusal interferences, dental and/ or periodontal problems, tooth loss, muscle and/or temporomandibular joints problems².It is known that in a unilateral mastication, the chewing muscles are mainly characterized by increased muscle strength on the working side, in other words, where chewing is occurring. The muscles of the balancing side, opposite side to the working side, is generally more elongated and with NTRODUCTIONChewing is considered by many authors as one of the most important and most studied functions of the stomatognathic system¹,². When performed in a alternating bilateral way, there is synchrony of masticatory muscles, which in turn are crucial for the ABSTRACT Purpose: to investigate the relationship of the masticatory preference side in the electrical activity of masseter and temporalis muscles. Methods: the sample was composed by 115 children aged between 7 and 12 years. The acquisition of the electrical activity of the masticatory muscles was recorded during 5 seconds of isometric contraction in maximal intercuspal position. The children were divided into four groups according to masticatory preference observed: Chewing Preferential Right, Left, Bilateral Alternating, and Bilateral Simultaneous. The electromyographicdata were analyzed using the SPSS 17.0 software, and for determination of statistical difference between the electrical activity of the right and left masseter and temporalis muscles was performed by Paired Student t-test (p <0.05). Results: from the total of 115 children, 76 (63.4%) had a preferred side during mastication, whereas 44 (36.7%) children had masticatory right and 32 (26.7%) preferred chewing left. Of the individuals without a preferred side, it was found 25.8% (n = 31) alternating with bilateral chewing and 10.8% (n = 13) with simultaneous bilateral chewing. After comparing the electrical activity of the masseter and temporal, right and left, according to the group chewing, it was found that the average electrical activity of the muscles on the left side showed no statistically significant differences when compared with the average of its peers right side. Conclusion: for the study sample, there was no relationship between the habitual chewing side and electrical activity of the muscles masseter and temporal.

“…Different oral health conditions in the elderly (edentulous, partially edentulous, using removable dentures) result in reduced bite force, with no impact on their chewing ability (2) . According to the literature, chewing in users of removable prostheses is characterized by changes in food cutting, chewing type and labial function (5) . On the other hand, implant supported prostheses decrease the difficulty in chewing (6) , improve psychological conditions, the masticatory function, aesthetics (7) , the bite force and chewing efficiency (8) in healthy elderly.…”

Purpose: To relate the findings of oral diadochokinesis (DDK) and masticatory function in healthy elderly. Methods: Analysis of medical records and images files of 35 healthy elderly subjects aged 60 to 74 years. The masticatory type and other behaviors associated with mastication of bread (1cm thick), the analysis of food seizure, bolus formation and measurement of chewing time, using a timer, were considered. For DDK assessment, the syllabic emissions "pa", "ta", "ka" and the tri-syllable "pataka", as to the parameters automatically provided Para o tipo mastigatório, apreensão e formação do bolo alimentar não houve correlação com os dados da DDC oral. Conclusão: A DDC oral correlacionou-se com o tempo mastigatório em idosos saudáveis, evidenciando que, quanto maior a instabilidade na repetição dos movimentos de ponta e dorso de língua durante a produção articulatória, maior o tempo necessário para a preparação do alimento para a deglutição.Descritores: Envelhecimento; Saúde do idoso; Mastigação; Avaliação;Testes de articulação da fala Study conducted at the Speech Therapy Course,

“…Phonoaudiology Teachers [18] developed a survey of 53 individuals of both genres, aged 42-67 years, divided into two groups, where group 1 was composed of 32 users of total or partial removable prosthesis, and group 2 was composed of non-users of prostheses. In the evaluation, the food used was the bread of salt (French bread) and the chewing time was determined in seconds.…”

Background: Researchers in Speech Therapy usually state that the food texture consumed influences considerably the chewing time and that therefore it is important to understand the duration of this oral function for different food textures, in order to have a greater objectivity in the evaluations. Thus, normative and comparative patterns can be developed between different cases, with the intention of enriching the clinical practice and having scientific support that guides the speech-language pathology. So, the objective os this study was to obtain reference values of chewing time of several food textures in young adults. Methods and Findings:descriptive study with a quantitative approach that was developed in a clinical reference, being the population composed of 40 young adults between 18-30 years of age, of both genres. As exclusion criteria: those with neuromuscular and/or degenerative diseases or consequences thereof, as well as subjects who were making use of any orthodontic/orthopedic resource. We conducted a dental evaluation, followed by a clinical assessment. One at a time, the following foods were offered: French bread, wafer biscuit, roasted cashews, for voluntary chewing. To measure the food chewing time, we used a stopwatch, and this collection procedure was filmed. Data analysis was performed by means of the SPSS statistics 20.0 (IBM ® ) program. There was a statistically significant difference (p < 0.05) between the medians of chewing time of French bread, wafer biscuit and cashew nuts, which were 33.0s (interquartile amplitude 29.0-40.0), 10.0s (interquartile amplitude 8.25-12.0) and 18.5s (interquartile amplitude 15.0-23.75), respectively. Conclusions:The texture of foods influences the length of mastication. The more rigid is the food, the more cycles and mandibular movements, and therefore the longer chewing duration.
