Abstract
To investigate the masticatory and swallowing performances in patients with malocclusions before and after orthodontic treatment, comparing them to an age- and gender-matched control group with normal occlusion.
Twenty-three patients with malocclusions requiring orthodontic treatment were included in this prospective study. One month after appliance removal, seventeen patients completed a follow-up examination and the data were compared with those of a control group with thirty subjects with normal occlusion. Masticatory performance was determined by the median particle size for the Optocal Plus® test food after 15 chewing strokes, and three variables related to swallowing were assessed: a) time and b) number of strokes needed to prepare the test-food for swallowing, and c) median particle size of the crushed particles at the moment of swallowing.
At the baseline examination, the malocclusion group had a significantly lower masticatory performance and did not reach the particle size reduction at the moment of swallowing, when compared with the control group. After treatment, the masticatory performance significantly improved in the malocclusion group and the particle size reduction at swallowing reached the same level as in the control group.
The present results showed that the correction of malocclusions with fixed appliances can objectively provide positive effects in both mastication and deglutition processes, reinforcing that besides aesthetic reasons, there are also functional indications for orthodontic treatment.

One month after appliance removal, seventeen patients completed a follow-up examination and the data were compared with those of a control group with thirty subjects with normal occlusion. Masticatory performance was determined by the median particle size for the Optocal Plus<sup>®</sup> test food after 15 chewing strokes, and three variables related to swallowing were assessed: a) time and b) number of strokes needed to prepare the test-food for swallowing, and c) median particle size of the crushed particles at the moment of swallowing. </p></sec><sec><title>Results: </title><p>At the baseline examination, the malocclusion group had a significantly lower masticatory performance and did not reach the particle size reduction at the moment of swallowing, when compared with the control group. After treatment, the masticatory performance significantly improved in the malocclusion group and the particle size reduction at swallowing reached the same level as in the control group. </p></sec><sec><title>Conclusions: </title><p>The present results showed that the correction of malocclusions with fixed appliances can objectively provide positive effects in both mastication and deglutition processes, reinforcing that besides aesthetic reasons, there are also functional indications for orthodontic treatment.</p></sec></abstract><trans-abstract xml:lang="pt"><title>RESUMO</title><sec><title>Objetivo:</title><p> investigar as performances mastigatória e de deglutição em pacientes com má oclusão, antes e após o tratamento ortodôntico, comparando-os com um grupo controle com oclusão normal, equiparado por idade e sexo. </p></sec><sec><title>Métodos: </title><p>vinte e três pacientes com má oclusão requerendo tratamento ortodôntico foram incluídos neste estudo prospectivo. Um mês após a remoção dos aparelhos, dezessete pacientes completaram os exames de acompanhamento, e seus dados foram comparados com aqueles de um grupo controle com trinta indivíduos com oclusão normal. A performance mastigatória foi determinada pelo tamanho mediano das partículas do alimento teste Optocal Plus<sup>®</sup> após 15 ciclos mastigatórios, e três variáveis relacionadas à deglutição foram avaliadas: a) tempo e b) número de ciclos necessários para preparar o alimento teste para deglutição, e c) tamanho mediano das partículas trituradas no momento da deglutição. </p></sec><sec><title>Resultados:</title><p> no exame inicial, o grupo com má oclusão apresentou uma menor performance mastigatória e não atingiu a redução do tamanho das partículas no momento da deglutição, quando comparado com o grupo controle. Após o tratamento, a performance mastigatória aumentou significativamente no grupo com má oclusão, e a redução do tamanho das partículas no momento da deglutição atingiu o mesmo nível do grupo controle. </p></sec><sec><title>Conclusões:</title><p> os resultados demonstraram que a correção das más oclusões com aparelhos fixos pode, objetivamente, proporcionar efeitos positivos nos processos de mastigação e deglutição, reforçando que, além de razões estéticas, existem também indicações funcionais para o tratamento ortodôntico.</p></sec></trans-abstract><kwd-group><title>Keywords:</title><kwd>Malocclusion</kwd><kwd>Masticatory performance</kwd><kwd>Deglutition.</kwd></kwd-group><counts><fig-count count="0"></fig-count><table-count count="3"></table-count><equation-count count="0"></equation-count><ref-count count="30"></ref-count><page-count count="7"></page-count></counts></article-meta></front></pmc><affiliations><list><country><li>Brésil</li></country><region><li>Minas Gerais</li><li>Rio Grande do Sul</li></region><settlement><li>Porto Alegre</li></settlement><orgName><li>Université fédérale du Rio Grande do Sul</li></orgName></list><tree><country name="Brésil"><region name="Rio Grande do Sul"><name sortKey="Gameiro, Gustavo Hauber" sort="Gameiro, Gustavo Hauber" uniqKey="Gameiro G" first="Gustavo Hauber" last="Gameiro">Gustavo Hauber Gameiro</name></region><name sortKey="Andrade, Annicele Silva" sort="Andrade, Annicele Silva" uniqKey="Andrade A" first="Annicele Silva" last="Andrade">Annicele Silva Andrade</name><name sortKey="Magalhaes, Isabela Brandao" sort="Magalhaes, Isabela Brandao" uniqKey="Magalhaes I" first="Isabela Brandão" last="Magalhães">Isabela Brandão Magalhães</name><name sortKey="Szymanski, Mariana Marcon" sort="Szymanski, Mariana Marcon" uniqKey="Szymanski M" first="Mariana Marcon" last="Szymanski">Mariana Marcon Szymanski</name></country></tree></affiliations></record>Pour manipuler ce document sous Unix (Dilib)
