The Promising Applications of Stem Cells in the Oral Region: Literature Review.

Introduction: For a long time researchers have tried to find out a way to grow tissues back to the human body in order to solve transplantation problems by offering the unique opportunity to have their organs back, working properly, in search of life dignity.

Literature Review: Stem cells seem to be present in many other tissues than researchers had once thought; and in some specific sites they can be easily collected, without the need of expensive interventions. The oral cavity is one of these regions where their collection can be accomplished, with plenty of accessible sites enriched with these precious cells.

The influence of composite resin restorations and lining on radiographic diagnosis and decision-making: an in vitro investigation.

The objective of this study was to evaluate the influence of resin-based restorations on the interpretation of digital and conventional radiographic images and to correlate the proposed diagnosis with decision-making. Class II cavities were prepared in one of the proximal surfaces of extracted human molars. Teeth were divided into five groups (n = 10) according to the restoratives used: Natural Flow (NF) and Filtek Supreme (FS); Filtek Flow (FF) and FS; Tetric Flow (TF) and FS; Protect Liner F (PLF) and FS; and FS alone.

Lymphangioma mimicking apical periodontitis.

Introduction: Lymphangiomas mimicking apical periodontitis, usually found in soft tissue of children and infants younger than 2 years, are extremely rare in aged patients, particularly in bone tissues.

Methods: An 81-year-old woman was seen in a radiological service to undergo imaging studies for the placement of dental implants. A panoramic radiograph showed a radiolucent multilocular structure in the left mandibular molar region, where teeth #17 and #18 had previously been treated endodontically.

Correlation of the radiographic and morphological features of the dental follicle of third molars with incomplete root formation.

The objective of this study was to determine the correlation of the radiographic and morphological features of the dental follicle of unerupted third molars with incomplete root formation. A cross-sectional study was carried out with 56 patients (105 teeth) aged 13 to 24 years. Panoramic radiography was used to determine the stage of root formation to locate and measure pericoronal radiolucency.

Oral complaints in progressive systemic sclerosis: two cases report.

Progressive systemic sclerosis is a chronic sclerotic disease which causes diffuse, increased deposition of extracellular matrix in connective tissue with vascular abnormalities, resulting in tissue hypoxia. Aesthetic and facial dysfunction are followed by important oral and facial manifestation of disturbances such as xerostomia, the lack of saliva in the mouth, and its associated complications. Most clinical manifestations begin with tongue rigidity.

Eosinophilic granuloma in the jaws.

Eosinophilic granuloma is the most common expression of Langerhans cell histiocytosis and corresponds with typical bone lesions. This disease is of importance to dental professionals because early clinical signs can occur in the jaw and can cause extensive destruction of the periodontal tissues. Pathological fracture is an unusual finding.

Obstruction of the left ventricular outflow tract after mitral valvuloplasty with implantation of Gregori's ring.

Mitral valvuloplasty is efficient for repairing mitral valve disease with few complications. In some cases, obstruction of the left ventricular outflow tract may occur due to systolic anterior motion of the mitral valve. We report the case of a patient with this complication and a pressure gradient between the left ventricle and the aorta of 130 mm Hg after mitral valvuloplasty with implantation of a Gregori's ring.
