1. Sialendoscopy for Improvement of Salivary Flow in Patients with Sjögren Syndrome - Comparative Analysis of Intraglandular Washing Solutions
Abstract Introduction Among the potential diseases that present altered salivary flow and activity is Sjögren syndrome. Sialendoscopy seems to be an important therapeutic option. Objective To compare the results obtained with sialendoscopy for improving salivary flow measured by scintigraphy in patients with primary Sjögren syndrome to those obtained wit

2. Histopathological changes in parotid gland following submandibular gland failure: an experimental animal study
Resumo Introdução: As glândulas submandibulares estão expostas a muitos efeitos causados por doenças e intervenções terapêuticas. Estudos que avaliam o efeito da disfunção da glândula submandibular na glândula parótida ainda não foram reportados na literatura. Objetivo: O objetivo deste estudo foi avaliar as alterações histopatológicas na

3. Differential immunohistochemical expression of type I collagen and matrix metalloproteinase 2 among major salivary glands of young and geriatric mice
Abstract Objective This study aimed to demonstrate the immunohistochemical changes associated with MMP-2 and type 1 collagen separately for the first time in the major salivary glands (the parotid, submaxillary, and sublingual glands) that occur with aging in mice. Material and Methods Fourteen Balb/c white mice (50-80 g) were used in this study. The ani

4. Absorbed doses in salivary and thyroid glands from panoramic radiography and cone beam computed tomography
Abstract Introduction: Panoramic radiography and cone beam computed tomography (CBCT) are very important in the diagnosis of oral diseases, however patients are exposed to the risk of ionizing radiation. This paper describes our study aimed at comparing absorbed doses in the salivary glands and thyroid due to panoramic radiography and CBCT and estimating ra

5. Do you know this syndrome? Heerfordt-Waldenström syndrome
Abstract: Heerfordt-Waldenström syndrome is a rare subacute variant of sarcoidosis, characterized by enlargement of the parotid or salivary glands, facial nerve paralysis and anterior uveitis. Granulomas with a peripheral lymphocyte deficit are found in the anatomic pathology of affected organs. It is normally self-limiting, with cure achieved between 12 an

6. The accuracy of fine-needle aspiration cytology for diagnosis of parotid gland masses: a clinicopathological study of 114 patients
ABSTRACT Objective Fine-needle aspiration cytology is a valuable method for preoperative assessment of head and neck tumors. However, its accuracy in detection of salivary gland masses is controversial compared with other methods. The aim of this work was to evaluate the effectiveness and accuracy of fine-needle aspiration cytology (FNAC) in the diagnosis

7. Nifedipine-induced histological changes in the parotid glands of hypertensive rats
Nifedipine is a widely used anti-anginal and anti-hypertensive agent. It is associated with significant gingival changes attributed more to collagen hyperplasia than to enhancement of protein synthesis. We investigated the influence of nifedipine on morphological changes in the parotid glands of rats in a model of hypertension. Twenty-eight male Wistar rats

8. Synchronous Bilateral Warthin Tumors: A Case Report
Introduction Warthin tumor is described as papillary cystadenoma lymphomatosum and is the second most common tumor of the parotid glands. Bilateral synchronous incidence is rare, occurring in 7 to 10% of the cases. It is more common in males between 60 and 70 years of age and is closely related to smoking. There is slow growth and the condition is a delimi

9. Effect of astaxanthin and fish oil on enzymatic antioxidant system and ?-amylase activity of salivary glands from rats
Salivary glands contribute to oral health. It is therefore of interest to study therapies that may favor their function and protection. AIM: To evaluate the effect of astaxanthin, fish oil and association of them on enzymatic antioxidant system and functional parameters of salivary glands. METHODS: Healthy rats (n=32) were divided into 4 groups: untreate

10. Effect of fractionated radiotherapy on the parotid gland: an experimental study in Brazilian minipigs
INTRODUCTION: Radiotherapy (RT) of head and neck neoplasms often damages the salivary glands. AIM: To examine the pattern of morphologic changes resulting from RT of the head and neck region in minipig parotid glands in a clinical and experimental research setting. METHODS: Twelve 18-month-old male Brazilian minipigs weighing 30-40 kg were selected. Eight mi

11. Radioprotective Effect of Vitamin E in Parotid Glands: a Morphometric Analysis in Rats
O objetivo neste estudo foi avaliar o efeito radioprotetor da vitamina E sobre glândulas parótidas de ratos por meio de análise morfométrica. Sessenta ratos machos foram divididos em cinco grupos: controle, no qual os animais receberam solução de óleo de oliva; óleo de oliva irradiado, em que os animais receberam óleo de oliva e foram irradiados com

12. Pleomorphic adenoma with extensive squamous metaplasia and keratin cyst formations in minor salivary gland: a case report
Pleomorphic adenoma (PA), the most common salivary gland tumor, accounts for 54 to 65% of all salivary gland neoplasias and 80% of the benign salivary gland tumors. It most frequently affects the parotid gland, followed by the submandibular and the minor salivary glands. Microscopically, mucous, sebaceous, oncocytic and squamous metaplasia, sometimes with th
