In Brazil, there are 15,500 incident cases of oral cancer (OC) yearly, and early diagnosis is the main factor for a better prognosis. The objective of this study was to analyze the interval between the first symptoms, diagnosis, and treatment commencement in patients with malignant neoplasms in the oral cavity, lips, and oropharynx diagnosed between 2012-2018. Epidemiological data, duration, history of lesion, biopsy, and diagnosis were obtained from the medical records of these patients, who were then contacted via phone and interviewed about their oncological treatment.

Background: Juvenile spongiotic gingival hyperplasia (JSGH) is a benign proliferation of non-keratinised stratified squamous epithelium with evident spongiosis, exocytosis leukocytes and dilated vessels with varying numbers of inflammatory cells. Although uncertain, it has been suggested that the epithelial proliferation is probably related to trauma and local irritants. It emerges as a painless erythematous patch or papule with an irregular surface.

Oral alterations in patients diagnosed with eating disorders (ED) are reported in the literature, but few articles demonstrate these changes in a specific population. This study aims to summarize the findings of 26 patients with ED in a Brazilian dental clinic, through analyzing the body mass index and oral conditions (decayed, missing and filled teeth-DMFT, dental wear, salivary flux, xerostomia, oral hygiene-OHI-S, oral lesions, and the prevalence of candidiasis), in order to facilitate recognition and enable accurate diagnosis for the general dentist. Probably, the premature diagnosis of ED resulted in lower DMFT and oral lesions.

The present study aimed to evaluate the Fine Needle Aspiration Biopsy in different staining techniques in nodular lesions of the oral cavity and head and neck region, as their sensitivity, specificity and accuracy, staining with Panoptic, Papanicolaou and Hematoxylin-Eosin (H&E) stains. 46 patients who sought the Clinic of the Discipline of Clinical Stomatology at FOUSP were selected consecutively, with nodular lesions in the oral cavity and head and neck region. The material obtained by FNAB was sent on 6 different slides, stained by the method of Panoptic, Papanicolaou and H&E, to the same pathologist only with the clinical diagnosis.

Progress in cancer management by health systems involves improvements in surveillance, organization of healthcare services, specific programs focused on primary and secondary prevention, and scientific and technical advances in diagnosis and treatment. Despite well-known progress in the management of malignant neoplasms in all the above areas, oral cancer displays persistently high morbidity and mortality rates, apparently failing to reflect the accumulated scientific knowledge on the disease. The current article discusses the reasons for this mismatch, the need for redefining priorities in oral cancer management, and the implementation of such priorities as a public health policy.
