The aim of this study was to quantify the microorganisms Streptococcus mutans and Candida sp in the oral cavity of patients with oropharynx carcinoma, before, during and after radiotherapy, and to correlate the results with salivary factors such as pH, buffer capacity (CT) and flow rate (FS). Saliva samples were collected, diluted and inoculated in SB-20 agar and in Sabouraud agar, for Streptococcus mutans and Candida sp, respectively. Previously to dilution, the concentrated saliva was analyzed, and the salivary factors were determined. After the growth of colonies, the number of microorganisms was determined in CFU/ml. The analysis of the results allowed to conclude that the salivary factors are related to the presence of microorganisms, and that the number of CFU/ml increased as salivary flow rate decreased. The effects of radiation compromised salivary homeostasis and favored the increase of infection by yeasts and bacteria.

The discrepancy between subjective and objective analyses may be indicative of the limited precision of clinical testing for subjective impressions assessment.

Objetivo: avaliar a estabilidade de cirurgias bimaxilares com fixação interna rígida, na qual promoveu-se uma rotação anti-horária da mandíbula e conseqüente redução do ângulo do plano oclusal. Metodologia: foram estudados 15 pacientes com padrão facial de Classe II e deficiência mandibular. Os movimentos cirúrgicos foram avaliados por meio de medidas lineares e angulares realizadas no programa CefX, obtidas de telerradiografias cefalométricas em norma lateral em três diferentes tempos: (T0) pré-operatório, (T1) pós-operatório imediato e (T2) pós-operatório de no mínimo 6 meses. Resultados e Conclusões: os resultados demonstraram que a cirurgia bimaxilar promove mudanças faciais significativas e, principalmente, que a rotação anti-horária da mandíbula com redução do ângulo do plano oclusal mostrou-se estatisticamente estável, sendo uma opção confiável em cirurgias de pacientes com padrão facial de Classe II com deficiência mandibular.

Sialolithiasis is a common nonneoplastic disease of the major salivary glands that often affects the submandibular glands. Minor salivary gland involvement by sialolithiasis is uncommon, with only 273 cases reported. A long clinical history, acute symptoms, and mucopurulent discharge are unusual features of these cases. Herein, we report the case of a 63-year-old woman who complained of symptomatic nodular swelling of the buccal mucosa associated with purulent discharge for several days. The clinical history lasted 15 years, with episodes of asymptomatic non-suppurative swelling in the same area. The patient underwent surgical excision. The microscopic examination revealed chronic nonspecific sialadenitis associated with psammomatous calcifications, confirming minor salivary gland sialolithiasis. After 3 years of follow-up, the patient was free of symptoms. Patients with sialolithiasis are usually asymptomatic; however, swelling, pain, and fistula may be present in rare cases. The presence of purulent exudate should lead to the differential diagnosis of stomatitis glandularis, a rare inflammatory condition affecting the minor salivary glands. Sialolithiasis and stomatitis glandularis should be considered in the clinical differential diagnosis of symptomatic suppurative nodular swelling affecting the oral mucosa, and histopathological analysis is necessary for the diagnosis.

ResumoA assimetria facial, mais propriamente a assimetria mandibular, está relacionada com diversos fatores etiológicos. Estes passam por fatores de ordem congênita e de desenvolvimento ou fatores de ordem adquirida. Osteocondroma de côndilo mandibular é raro na região craniofacial. Este artigo descreve um caso de osteocondroma de côndilo mandibular em uma mulher de 27 anos que foi encaminhada ao nosso serviço apresentando assimetria facial, desvio de mento, mordida cruzada para o lado contralateral, alterações na morfologia do côndilo, limitação de abertura bucal e má-oclusão. Devido à base no exame clínico, histórico do paciente e exames complementares, foi estabelecida uma hipótese de osteocondroma. Um procedimento de condilectomia utilizando abordagem pré-auricular com uma total remoção da lesão foi executado. Descritores: Osteocondroma; Côndilo Mandibular; Assimetria Facial. AbstractThe facial asymmetry, more properly the mandibular asymmetry, is related to several etiological factors. These are related to congenital and development factors or acquired factors. Osteochondroma of the mandibular condyle has been found in the oral and maxillofacial region rarely. This paper describes a case of osteochondroma of the mandibular condyle in a 27-year-old woman, who was referred to our service with facial asymmetry, prognathic deviation of chin, cross-bite to the contralateral side, changes in condylar morphology, limited mouth opening, and malocclusion. Based on the clinical examination, patient history, and complementary exams, the hypothesis of osteochondroma was established. Condylectomy was performed using a preauricular approach with total removal of the lesion. Descriptors: Osteochondroma; Mandibular Condyle; Facial Asymmetry.

Porque se basa en el examen clínico, la historia y las pruebas de laboratorio de los pacientes, se estableció una hipótesis de osteocondroma. Se realizó un procedimiento condilectomía utilizando el enfoque preauricular con una eliminación total de la lesión.
