Adaptações do sistema estomatognático em indivíduos com desproporções maxilo-mandibulares: revisão da literatura

This research had the aim to identify adaptations on the stomatognathic system of individuals with maxillomandibular disproportions. The literature review was carried out using national and international databases, addressing adaptations on the stomatognathic system of subjects with maxillomandibular disproportions submitted to orthognathic surgery associated to speech-language intervention. It was found that subjects with prognathism and retrognathism present adaptations in all oral-motor functions during the presurgical period. In mandibular prognathism, the most adapted function is mastication, which is characterized by vertical movements using the dorsum of the tongue for kneading the food, and less use of the masticatory muscles. In mandibular retrognathism, studies showed that deglutition is most adapted, being characterized by anterior mandibular slide, in addition to postero-anterior movement of the tongue and perioral muscles activation. After orthognathic surgery, some cases may present adequacy of the stomatognathic system functions. In other, however, adaptations may persist, making it necessary that speech-language therapists are well informed about pre-existent adaptations, in order to plan the best rehabilitation process for each case.

Ansiedade frente ao tratamento odontológico: prevalência e fatores predictores em brasileiros

Considering the negative impact anxiety can exert over dental treatment, the scope of this study was to determine the prevalence of predictors of anxiety regarding dental treatment among Brazilians. A cross-sectional study was carried out using the Corah dental anxiety scale to assess the degree of anxiety regarding dental treatment among 3000 patients. The results reveal that two out of every eight Brazilian patients manifest moderate to severe anxiety regarding dental treatment. In this sample, the degree of anxiety was higher among females (p=0.007), over 20 years of age (p=0.006), without access to the Internet and/or newspapers (p=0.016), with a low frequency of oral hygiene (p=0.001), for whom the reason for the dental appointment was curative treatment, pain or another problem rather than a check up (p=0.047) and those suffering from toothache (p<0.001). Fear and anxiety regarding dental treatment indeed exist in the Brazilian population and the findings of this study suggest that, besides the lack of economic resources, negligence with respect to oral health, gender and age may increase the degree of anxiety.
