Evaluation of the biocompatibility of silicone gel implants - histomorphometric study.

NONE DECLARED Breast implants are medical devices that are used to augment breast size or to reconstruct the breast following mastectomy or to correct a congenital abnormality. Breast implants consist of a silicone outer shell and a filler (most commonly silicone gel or saline). Approximately 5 to 10 million women worldwide have breast implants.

Biocompatibility evaluation of 3 facial silicone elastomers.

The failure of facial prostheses is caused by limitations in the properties of existing materials, especially the biocompatibility. This study aimed to evaluate the biocompatibility of maxillofacial silicones in subcutaneous tissue of rats. Thirty Wistar rats received subcutaneous implants of 3 maxillofacial silicone elastomers (LIM 6050, MDX 4-4210, and industrial Silastic 732 RTV).

Microbiota associated with chronic osteomyelitis of the jaws.

Chronic osteomyelitis of maxilla and mandible is rare in industrialized countries and its occurrence in developing countries is associated with trauma and surgery, and its microbial etiology has not been studied thoroughly. The aim of this investigation was to evaluate the microbiota associated with osteomyelitis of mandible or maxilla from some Brazilian patients. After clinical and radiographic evaluation, samples of bone sequestra, purulent secretion, and biopsies of granulomatous tissues from twenty-two patients with chronic osteomyelitis of mandible and maxilla were cultivated and submitted for pathogen detection by using a PCR method.

Osteolipoma of the buccal mucosa.

Lipomas are benign mesenchymal neoplasms of soft tissue that can be found in any part of the human body. Conversely, their presence in the oral mucosa is rather uncommon, with approximately 4% of the cases occurring in the oral cavity. In such cases, they are likely to have originated from mature adipose tissue and to be among several described histological variants of lipomas, which are identified according to the predominant type of tissue.

Influence of preventive dental treatment on mutans streptococci counts in patients undergoing head and neck radiotherapy.

Unlabelled: The aim of this study was to evaluate the influence of chlorhexidine gluconate, sodium fluoride and sodium iodine on mutans streptococci counts in saliva of irradiated patients.

Material And Methods: Forty-five patients were separated into three experimental groups and received chlorhexidine (0.12%), sodium fluoride (0.

Oral cysticercosis: case report.

Frequent in developing countries, cysticercosis is a parasitic infection that rarely involves the mouth. This study reports a case of oral cysticercosis in a 13-year-old female patient who had an asymptomatic nodule in the right labial mucosa. An excisional biopsy was carried out and the histopathologic examination revealed a cystic space containing a Taenia solium larva.
