RESUMO
A obstrução das glândulas salivares por cálculos acomete 90% dessas estruturas, apresentando geralmente tamanho menor que 1 cm. É encontrada, principalmente, nas glândulas submandibulares. Clinicamente, o paciente apresenta um aumento de volume na região referente à glândula salivar envolvida, podendo apresentar sintomatologia dolorosa e drenagem purulenta. O presente artigo relata um caso de sialólito gigante com 2,5 cm de diâmetro, em glândula submandibular, removido cirurgicamente, com preservação funcional da glândula submandibular. O tratamento pode variar de acordo com o tamanho, a forma e localização do cálculo... (AU)
The obstruction of the salivary glands by calculations affects 90% of these structures, usually exhibiting a size smaller than 1 cm. It is mainly found in the submandibular glands. Clinically, the patient presents an increase in volume in the region related to the salivary gland involved and may present painful symptoms and purulent drainage. The present article reports a case of giant sialolith with a diameter of 2.5 cm in the submandibular gland, which was removed surgically with functional preservation of the submandibular gland. The treatment may vary according to the size, shape and location of the calculus... (AU)

Objetivo. Determinar la prevalencia de cálculos salivales en la glándula submaxilar, así como la prevalencia según edad, sexo, ubicación en el conducto y lado afectado, mediante la evaluación de tomografías computarizadas de haz cónico en pacientes de 18 a70 años. Materiales y métodos. Se evaluó 580 tomografías computarizadas de haz cónico (258 de pacientes de sexo masculino y 322 de pacientes de sexo femenino). Las tomografías pertenecieron al centro de diagnóstico maxilofacial y al centro de diagnóstico por imágenes. Se seleccionaron aquellas tomografías que cumplieron los criterios de inclusión, obteniendo la muestra por conveniencia. Resultados. Se observó la presencia de nueve cálculos salivales (1,6%), los cuales más de la mitad estuvieron localizados en el sector posterior del conducto con leve predilección por el lado izquierdo. También se apreció mayor prevalencia entre la cuarta y sexta década de vida. Conclusiones. La prevalencia de cálculos salivales evaluado mediante tomografía computarizada de haz cónico en nuestra población es 1,6%. Así mismo, se confirmó que esta enfermedad tiene mayor prevalencia en personas de 45 a 70 años, y en el sector posterior del conducto salival. Los resultados fueron similares entre ambos sexos, de igual manera sucedió con respecto al lado afectado.
Objective. To determine the prevalence of salivary calculi in the submandibular gland, as well as the prevalence by age, sex, location on the canal and affected side, through the evaluation of cone beam computed tomographies in patients of 18 to 70 years old. Materials and methods. 580 cone beam computed tomographies were evaluated (258 of male patients and 322 of femalepatients). Tomographies were of the ôcentro de diagnóstico maxilofacialõ and ôcentro de diagnóstico por imágenesõ. Tomographies that accomplish the inclusion criteria were selected. The sample was obtained by convenience. Results. 9 salivary calculi (1.6%)was observed, more than half were located in the back left area. Also a higher prevalence between the fourth and sixth decades of life was obtained. Conclusions. The prevalence of salivary calculi evaluated by cone beam computed tomography in our populationis 1.6%. Also, this disease is more prevalent in people between 45-70 years old, and in the back area of the salivary canal. Similar results were obtained in each sex, the same happened with the affected side.

OBJECTIVES: The aims of this study were to investigate the caries experience, periodontal status, oral hygiene habits, and salivary parameters of children and adolescents undergoing hemodialysis (HD) and to compare them with their healthy counterparts. METHODS: Fifty-two HD patients were matched for age, sex, ethnicity, and social class with 52 healthy subjects for analysis of the number of decayed, missing and filled teeth, plaque and gingival index, dental calculus accumulation, measurements of pocket depth, clinical attachment level, gingival recession, and bleeding on probing. Stimulated saliva samples were collected to assess salivary flow rate, pH and buffer capacity, and salivary concentrations of calcium, phosphate, and urea by colorimetric method. RESULTS: HD patients had lower dental caries (p = 0.004), greater plaque and calculus accumulation (p = 0.001), and reported flossing less often than the controls (p = 0.013). Regarding salivary analysis, HD patients showed significantly higher values of pH, buffer capacity, and salivary urea concentration when compared to the controls (p = 0.001). CONCLUSION: HD patients had lower caries experience, higher accumulation of dental plaque, and calculus deposition than their healthy counterparts, probably due to the differences found in their salivary biochemical parameters. CLINICAL SIGNIFICANCE: A significant number of children and adolescents undergoing hemodialysis are candidates for kidney transplantation and should receive complete pre-transplant dental exams and dental treatment. Our results open the way for the development of an individualized dental protocol for these patients with preventive measures and treatment of the poor oral health in HD patients.

Mudanças no tamanho de uma glândula salivar podem indicar doenças sistêmicas. Porém, é difícil avaliar corretamente estas mudanças somente através de exame clínico. Métodos complementares podem auxiliar de forma fundamental no diagnóstico. Por causa da importância de se identificar pequenos cálculos nas glândulas salivares como a causa de um conjunto de sintomas, radiografias intrabucais etomografia computadorizada são os melhores exames para uma avaliação inicial. A sialografia pode ser utilizada na avaliação de sialoadenites crônicas. Os autores discutem estes e outros exames,como a cintilografia e a ultra-sonografia, no diagnóstico e no tratamento das patologias das glândulas salivares

Relata-se o caso de paciente do sexo feminino com um cálculo salivar no conduto da glândula submandibular documentado na clínica de Pós-Graduação em Estomatologia da UFPB. Após confirmação diagnóstica por radiografia oclusal, tentou-se remover o cálculo por meio de estímulo por massagem, o que não foi possível. O sialolito foi retirado através de pequena incisão cirúrgica sob anestesia infiltrativa local e apresentou-se com cerca de um centímetro de diâmetro aproximadamente.

La sialolitiasis constituye uno de los factores más comunes de disfunción de las glándulas salivales. El éxtasis de la secreción salival producida por la presencia de cálculos en el conducto, con una subsecuente infección bacteriana piógena es la causa más frecuente de sialoadenitis cronica. Se reporta un caso de sialoadenitis por sialolitiasis en la glándula submandibular izquierda, cuyo diagnostico inicial, por el servicio de urgencia del Hospital San Juan de Dios de Cali, fue absceso submandibular. Posteriores estudios, en el servicio de cirugía oral y maxilofacial de la misma institución, llevaron al hallazgo de sialoadenitis de glándula submandibular por retención de flujo e infección. El tratamiento de elección fue la excisión de la glándula por la evolución cronica. En el informe posterior de patología se reporto un proceso inflamatorio severo con el estroma densamente infiltrado de linfocitos formando folículos linfoicles. Acinos no funcionales, canaliculos dilatadas con metaplasia escamosa, formación de cavidades quísticas sin evidencia de malignidad.
Sialolitiasis is one of the most common factors included in salivary gland disease. The principal cause of chronic sialoadenitis is the presence of calculus into the duct which produce a consecuent infection because of estasis of salivary secretion. A case of sialoadenitis is reported. The patient was admitted at the San Juan de Dios Hospital, in Cali. The initial diagnostic was a submandibular absces, however the test revealed a sialoadenitis of submandibular gland because off fluid retention and infection. The treatment was the gland excision. The histopatologic findings reported a severe inflamatory proces in wich the stroma was densely infiltrated by lymphocites that were fonning lynphoids follicles, acines with no function, dilated ducts with scalymethaplasia, cystical cavities without malignancy. One week after the sugery, the patient reported unconfortable for eating and felt her mouth and throat dry. Two months after, she was in good condition.
