Radiation-related caries is a disease with high potential of teeth destruction in patients who have undergone radiotherapy in the head and neck region. Also, it is a challenge for dentistry due to high rates of recurrent caries and early restorations failure. This study aims to analyze the early restoration failures in order to better understand the(More)
Paracoccidioidomycosis is a fungal infection caused by Paracoccidioides brasiliensis. It is an endemic disease, representing a serious health problem in Latin American countries. This infection primarily affects the lungs and is acquired by inhalation of the fungus. It can spread to other organs and tissues, mainly the oral cavity affecting more adult men(More)
We retrospectively analysed the clinical and histological characteristics of oral squamous cell carcinoma (SCC) in a sample of Brazilian patients 45 years of age or less. Files from a single oral histopathological service were studied during the period 1990 to 2005 and the clinical data collected. The histological sections of the invasive part of each(More)
Understanding the molecular mechanisms of oral carcinogenesis will yield important advances in diagnostics, prognostics, effective treatment, and outcome of oral cancer. Hence, in this study we have investigated the proteomic and peptidomic profiles by combining an orthotopic murine model of oral squamous cell carcinoma (OSCC), mass spectrometry-based(More)
Mucoepidermoid carcinoma (MEC) is the most common malignancy of salivary glands. The response of MEC to chemotherapy is unpredictable, and recent advances in cancer biology suggest the involvement of cancer stem cells (CSCs) in tumor progression and chemoresistance and radioresistance phenotype. We found that histone acetyltransferase inhibitors (HDACi)(More)
Amiodarone is one of the most commonly used drugs for treatment of cardiac arrhythmia. Several undesirable effects are associated with its long-term use. This report describes the case of a 71-year-old female patient, with a diagnosis of cardiac arrhythmia, who presented with a stigmatizing blue-gray facial pigmentation and altered serum values of thyroid(More)
Previous studies have demonstrated that myofibro-blasts in the adjacent stroma are involved in the development and progression of malignant tumors. The aim of this study was to investigate the involvement of myofibroblasts in the progression of oral squamous cell carcinomas (OSCCs) by determining myofibroblast density in potentially malignant and malignant(More)
Invasive multiple cervical root resorptions after vital tooth bleaching is a rare condition. The aim of this article is to present a case of multiple external cervical root resorptions (ECRR) after a misguided home whitening treatment. A 34-year-old male patient presented with slight sensitivity and mobility in several teeth. Despite the manufacturer's(More)
