Objective: To perform an epidemiological survey comparing the cell proliferative activity of 107 cases of oral leukoplakia with their clinical and histopathological characteristics.

Materials And Methods: A cross-sectional, observational, and histological-histochemical study. The cases came from the Histopathological Diagnostic Service of UPF/RS and the School of Dentistry of Araçatuba FOA/UNESP/SP (1986-2016).

Treatment of facial myiasis in an elderly patient with oral squamous cell carcinoma: Case report.

Unlabelled: Myiasis is caused by the infestation of fly larvae in human tissues and it presents immunodeficiency, poor hygiene, or malignant neoplasias as predisposing chronic diseases.

Objective: To describe a clinical case of myiasis associated with oral squamous cell carcinoma (OSCC) in an elderly patient.

Squamous cell carcinoma from oral lichen planus: a case report of a lesion with 28 years of evolution.

Lichen planus (LP) is a relatively common mucocutaneous disease with autoimmune etiology. Considering its malignancy potential, it is important to define the correct diagnosis, treatment, and clinical follow-up for patients with LP so that the disease is not diagnosed late, thus hindering the chances of curing the disease. This study aims to describe a clinical case of oral squamous cell carcinoma, potentially originated from LP.

Influence of Different Intellectual Disability Levels on Caries and Periodontal Disease.

Oral health care is fundamental to preserve the individual integrity and consequently influences the general health. This observational, cross-sectional and analytical study evaluated the oral condition of 129 intellectually disabled individuals from the Association of Parents and Friends of Exceptional Children (APAE) in three southern Brazilian cities. Dental caries (DMFT and dmft indices) and periodontal disease (PSR index) were evaluated considering the intellectual disability level.

Influence of in situ postbleaching times on shear bond strength of resin-based composite restorations.

Background: The authors conducted an in situ study of the influence of various time intervals after tooth bleaching with 35 percent hydrogen peroxide on the bond strength of resin-based composite restorations.

Methods: After selecting 20 participants, the authors randomly fixed enamel and dentin blocks onto the buccal surfaces of posterior maxillary teeth one week before performing tooth bleaching with 35 percent hydrogen peroxide. After the bleaching treatment, they removed one block of dentin or enamel and prepared it for the bond strength tests according to these time intervals: no bleaching treatment (controls), immediately after bleaching, seven days after bleaching, 14 days after bleaching and 21 days after bleaching.
