Comparison of halitosis parameters and sialometry between patients subjected to head and neck radiotherapy and patients with periodontal disease

The aim of this study was to evaluate halitosis parameters and sialometry in patients subjectedto head and neck radiotherapy compared to patients with periodontal disease, establishing arelationship between oral concentration of volatile sulfur compounds (VSCs) and tongue coatingpresence, salivary flow rate and BANATM test. Methods: Thirty-eight patients were examinedand divided into 2 groups: group I: patients with chronic generalized periodontal disease previouslydiagnosed and not treated; group II: patients subjected to head and neck radiotherapy. All volunteerswere subjected to halitosis measurements through a sulphide monitor, evaluation of tongue coatingweight, stimulated and non-stimulated sialometry and BANATM test. Results: The results wereanalyzed by analysis of the variance, Pearson’s correlation coefficient and Student’s t-test, showingthat both groups presented halitosis. There was also a relationship between tongue coatingpresence and VSC levels in both groups and the irradiated patients showed lower salivary flowrates. Conclusions: Under the tested conditions, it may be concluded that halitosis can beconsidered as an adverse effect of radiotherapy, associated with low salivary flow and poor oralhealth, which seems to be the main contribution to bad breath, since patients with periodontaldisease also showed halitosis.

Management of a parotid sialocelein a young patient: case report and literature review

Sialocele is a subcutaneous cavity containing saliva, caused by trauma or infection in the parotid gland parenchyma, laceration of the parotid duct or ductal stenosis with subsequent dilatation. It is characterized by an asymptomatic soft and mobile swelling on the parotid region. Imaging studies are useful and help establishing the diagnosis, such as sialography, ultrasonography, computed tomography and magnetic resonance imaging. This paper describes a recurrent case of a parotid sialocele in a young female patient. She presented a 6 cm x 5 cm swelling on the left parotid region. The ultrasonographic scan of the area revealed a hypoechoic ovoid well defined image suggesting a cyst. A sialography of the left parotid showed a cavitary sialectasia in a panoramic and anteroposterior view. A conservative management was adopted by percutaneous needle aspiration of the swelling, which was useful to provide material for analysis and helped healing. Dentists should be aware of this pathology and the importance in adopting a conservative treatment whenever it is possible.

O desenvolvimento do processo ensinoa prendizagem: / Development of the teaching and learning process: the point of view of the student and of the professor

Para que o ensino se constitua em prática vinculadaaos interesses maiores da sociedade, é necessáriauma redefinição dos projetos pedagógicos doscursos de graduação que rompa com os principaisproblemas já diagnosticados, como a fragmentaçãocurricular, as estratégias de ensino que estimulama passividade discente e a pouca integração ensinoserviços-comunidade. O professor e o aluno representampapel fundamental nesse sentido, visto seremresponsáveis diretos por essas mudanças. Opresente trabalho procurou conhecer e comparara visão de professores e alunos do Curso de Odontologiada UNIFOR sobre o papel do professor noaprendizado do aluno. Para tanto, foram entrevistadosalunos do 9º semestre e professores de todasas áreas de conhecimento. As respostas foram categorizadasde modo a poder expressar a visão maiscomum entre os dois grupos. Para a maioria dosalunos, os melhores professores são aqueles enquadradosnas categorias “relacional” (50,0 porcento) e “cognitivo”(37,1 porcento). Já para a maioria dos professores,os melhores alunos são aqueles que se enquadramna categoria “motivação” (65,4 porcento), relacionando oaprendizado do aluno a quanto este está estimuladopara aprender. O aspecto cognitivo, apesar de serentendido como importante por ambos, não foiconsiderado o mais importante para o desenvolvimentodo processo ensino-aprendizagem. Ao considerara motivação como o item mais importantepara identificar um bom aluno, o professor transferea responsabilidade do aprendizado exclusivamentepara o aluno. Tendo em vista o grande valorque o aluno imprime à relação interpessoal, é fundamentalque tal questão esteja presente na formaçãodo professor
