Panoramic Radiography in the Diagnosis of Carotid Artery Atheromas and the Associated Risk Factors

Atherosclerosis is a serious chronic disease, responsible for thousands of deaths worldwide and is characterized by thickening and loss of elasticity of the arterial walls, associated with the presence of atheromatous plaques. Various risk factors act directly on predisposition to the disease, among which the following are pointed out: diabetes mellitus, arterial hypertension and inadequate diet and eating habits. More recent researches have elucidated new risk factors acting in the development of this disease, such as, for example: periodontitis, chronic renal disease and menopause. The panoramic radiograph, commonly used in dental practice, makes it possible to see calcified atherosclerotic plaques that are eventually deposited in the carotid arteries. The aim of this review article was to emphasize the dentist’s important role in the detection of carotid artery atheromas in panoramic radiographs and the immediate referral of patients affected by these calcifications to doctors. In addition, the study intended to guide the dentist, especially the dental radiologist, with regard to differential diagnosis, which should be made taking into consideration particularly the triticeal cartilage when it is calcified

Avaliação de reabsorções radiculares apicais externas decorrentes de movimentação ortodôntica em radiografias periapicais com registro a posteriori

O objetivo deste estudo foi quantificar a reabsorção radicular apical externa em indivíduos submetidos a tratamento ortodôntico e correlacionar a reabsorção radicular com possíveis fatores predisponentes. A amostra incluiu 79 indivíduos, com idade média de 13,7 anos e dividida em 2 grupos, de indivíduos tratados sem e com exodontia dos primeiros pré-molares superiores. Foram selecionadas as radiografias periapicais dos incisivos centrais superiores, obtidas no início e no final do tratamento ortodôntico. As radiografias foram digitalizadas e inseridas no programa Regeemy® – Image Registration and Mosaicking v.0.2.43-RCB (DPI-INPE, São José dos Campos, SP, Brazil) e procedidos os registros a posteriori (correção de diferenças de projeção geométrica, densidade e contraste entre as duas radiografias). As mensurações dos incisivos centrais superiores, foram realizadas nas imagens referência (pré tratamento) e na versão registrada (pós-tratamento), no programa UTHSCSA Image Tool® (University of Texas Health Science Center at San Antonio), obtidas em pixels e convertidas em porcentagem. Os resultados mostraram que ocorreu reabsorção radicular estatisticamente significante em ambos os grupos, com maior reabsorção no grupo com exodontia (p0,05). O período do tratamento foi significantemente maior no grupo com exodontia e as reabsorções radiculares foram também maiores no grupo tratado com exodontias (p0,05). The treatment duration was found to be statistically higher for the extraction group as well as the root resorptions (p<0,05), although the later was statistically significant only for tooth #11. Statistically significant correlation was found only between root resorption and the difference between 1-NA pre and post-treatment for the extraction group (Rho=0,45; p<0,05). Based on...

EL USO DE SIALOGRAFÍA EN EL DIAGNÓSTICO Y TRATAMIENTO DE LA PAROTIDITIS RECURRENTE JUVENIL: PRESENTACIÓN DE UN CASO

La parotiditis recurrente juvenil (PRJ) es una enfermedad inflamatoria de la gl&aacute;ndula par&oacute;tida, generalmente se caracteriza por episodios recurrentes de hinchaz&oacute;n, dolor y fiebre. Despu&eacute;s de la parotiditis epid&eacute;mica, es la PRJ en los ni&ntilde;os, la segunda enfermedad m&aacute;s frecuente de las gl&aacute;ndulas salivales. La aparici&oacute;n de PRJ se produce alrededor de 6 a&ntilde;os de edad y hay una ligera predilecci&oacute;n por los varones. La etiolog&iacute;a de la enfermedad sigue siendo poco clara y los s&iacute;ntomas tienden a desaparecer con la pubertad. Este estudio reporta el caso de un joven de 12 a&ntilde;os que se present&oacute; a la Facultad de Odontolog&iacute;a de la Universidad Estadual Paulista, Sao Jos&eacute; dos Campos, con una historia de episodios recurrentes de hinchaz&oacute;n de la gl&aacute;ndula par&oacute;tida izquierda asociada con dolor, fiebre y secreci&oacute;n purulenta en los primeros eventos. Terminada la anamnesia, se decidi&oacute; por obtener sialograf&iacute;as de las dos gl&aacute;ndulas par&oacute;tidas con el uso de material de contraste Lipiodol UF 38% y radiograf&iacute;as panor&aacute;micas, seguidas por las evaluaciones morfol&oacute;gicas y funcionales. El paciente se encuentra hoy sin presentar recurrencia de la enfermedad y est&aacute; bajo seguimiento cl&iacute;nico. ABSTRACT The Juvenile Recurrent Parotitis (JRP) is an inflammatory disease of the parotid gland, usually characterized by recurrent episodes of swelling, pain and fever. After mumps, the PRJ in children is the second most prevalent disease of salivary glands. The emergence of PRJ occurs around 6 years old and there is a slight predilection for males.The etiology of the disease remains unclear and the symptoms tend to disappear with puberty. This study reports the case of a twelve years old boy who presented to the Dentistry School of S&atilde;o Paulo State University - campus S&atilde;o Jos&eacute; dos Campos- with a history of recurrent episodes of swelling of the left parotid gland associated with pain, fever and purulent discharge in the early events . Finished the anamnesis, sialography were performed with the use of Lipiodol UF 38% contrast material and panoramic radiographs on both parotid glands, followed by morphological and functional assessments. There was no recurrence of the disease and the patient is under follow-up

Noninvasive aspergillosis as a maxillary antrolith: report of a rare case.

Maxillary antrolithiasis is characterized by masses of tissue of endogenous or exogenous origin that calcify within the maxillary sinuses. Aspergillosis is a fungal disease in which the maxillary sinus is a primary site of infection. Aspergillosis mycetoma, its noninvasive form, is the most prevalent modality of the disease in the maxillary sinuses. In approximately half of the cases reported in the literature, calcification of the fungal mycelia, which later became antroliths, was verified. This article reports a rare case of the accidental discovery of a maxillary antrolith associated with noninvasive aspergillosis in an immunocompetent and asymptomatic 56-year-old woman. The diagnosis and therapeutic procedures used in treating the patient are discussed as well as the probable iatrogenic origin of the fungal pathology
