TEMA: o equilíbrio das estruturas e funções do sistema estomatognático depende do adequado funcionamento da Articulação Temporomandibular, e esta, por sua vez, precisa da oclusão dental correta para a realização das funções ao movimentar a mandíbula. O desequilíbrio muscular ou estrutural da Articulação Temporomandibular poderá acarretar em uma disfunção dessa articulação e causar sinais e sintomas diversos como manifestações auditivas do tipo zumbido e otalgia. OBJETIVO: realizou-se a revisão de literatura das áreas de fonoaudiologia, otorrinolaringologia e odontologia com pesquisas em bases de dados, artigos e livros, sendo selecionadas as literaturas de 1992 a 2008 relacionadas ao tema do trabalho, a fim de associar sintomas audiológicos com a Disfunção Temporomandibular e apontar a importância da atuação multiprofissional, dando ênfase à atuação fonoaudiológica, em tal disfunção. CONCLUSÃO: várias são as hipóteses que tentam explicar a relação existente entre a Disfunção Temporomandibular e as alterações auditivas. Verificamos que há um vínculo entre o sistema estomatognático e o sistema auditivo. Contudo, mais importante que somente associar os sistemas estomatognático e auditivo, a equipe multiprofissional envolvida na assistência à pacientes com Disfunção Temporomandibular, precisa ter conhecimento a respeito da anatomia e fisiologia da Articulação Temporomandibular, de suas disfunções, causas e consequências, sendo capaz de distinguir a terapêutica eficiente para cada disfunção e, por fim, analisar a conduta com encaminhamentos adequados para a evolução do caso.
Although microscopic alterations have been detected in tongues and salivary glands of chagasic patients and the identification of biomarkers in saliva has proved advantageous, there are no studies evaluating tongue function and total salivary IgA, IgG and IgM levels in chronic chagasic patients. The aim of this study was to evaluate tongue function, salivary flow rate, and total salivary IgA, IgG and IgM levels comparing chronic and non-chronic chagasic individuals. 37 patients were selected: chronic cardiac chagasic patients (n=6), chronic chagasic patients with the associated form of the disease (cardiopathy and megaesophagus) (n=11), and nonchagasic individuals (n=20). The tongue function underwent a phonoaudiological evaluation.The salivary f low rate was measured by sialometry. The total salivary IgA, IgG and IgM levels were evaluated by sandwich ELISA assay. Chagasic patients with the associated form of the disease presented higher salivary flow rate and lower salivary protein levels. No significant differences were noted in the lingual function or in the total salivary immunoglobulin levels among the groups. Although patients with chagasic megaesophagus presented higher levels of salivary flow and lower salivary protein, the fact that there were no significant differencesin lingual function and total salivary immunoglobulin levels among the groups led to the conclusion that chronic chagas disease does not modify the lingual function or the total IgA, IgG and IgM salivary levels. The present study was the first to evaluate the function of the tongue and salivary total immunoglobulin levels in Chagas disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
