Tooth extraction in patients on oral anticoagulants: prospective study conducted in 108 brazilian patients.

Introduction. Dental treatment performed in patients receiving continuous oral anticoagulant drug therapy is becoming increasingly common in dental offices. For these patients it is imperative to carry out careful anamnesis, as well as a multiprofessional clinical evaluation with regard to the risk and control of hemorrhagic or thromboembolic episodes.

Oral HPV infection in a bone marrow transplantation patient: a case report with atypical clinical presentation and unexpected outcome.

HPV (Human Papilloma Virus) is one of the most prevalent infections worlwide. Oral HPV infection may be associated with different diseases of oral cavitie. Although oral HPV infection occurs frequently, it rarely causes lesions.

Herpetic geometric glossitis: acyclovir resistant case in a patient with acute myelogenous leukemia.

Herpes simplex virus (HSV) infections in an immunocompromised host may be atypical in location and morphology. Lesions are more extensive and aggressive, slow healing or nonhealing and extremely painful. Intraoral lesions are ulcerative and may involve any intraoral, oropharyngeal, or esophageal site.

Oral involvement in chronic graft versus host disease: a prospective study of 19 Brazilian patients.

Chronic graft versus host disease (cGVHD) is the most common late complication of allogeneic bone marrow transplantation. The oral cavity is the most common site of cGVHD involvement. This study sought to investigate the incidence of oral cGVHD, as well as the disease's impact on a patient's quality of life and the kind of lesions that resulted.

Pemphigus vulgaris in a juvenile patient: case report.

Pemphigus vulgaris is a rare cause of oral mucosal ulceration that mainly affects middle-aged adults; the oral lesions of pemphigus are associated with cutaneous manifestations.

Benign teratoma of the buccal mucosa in a 9-year-old girl: report of case and review of the literature.

Teratomas are embryonal tumors composed of tissues from all 3 germinal layers with variable levels of maturity. Teratomas are rare in the head and neck region, representing less than 5% of all cases. In the head and neck the most common involved sites are the nasopharynx and cervical regions.

Candida in saliva of Brazilian hemophilic patients.

Hemophilia is a common hereditary hemorrhagic disorder, however little is known about the oral microflora of hemophilic patients. The aim of this study was to quantify the Candida and identify its species in non-stimulated saliva of hemophilic patients, and consider its relationship with clinical factors influencing Candida carriage. This study comprised evaluation of 86 hemophilic patients of the Hematology Center/UNICAMP and 43 healthy subjects as controls.

Human herpesvirus 6 in oral fluids from healthy individuals.

Background: Human herpesvirus 6 (HHV6) is the etiologic agent of exanthem subitum. The virus is latent in salivary glands and saliva is the main form of viral transmission. The objective of this study was to assess HHV6 incidence in the fluids from healthy individuals using a standardised technique for collecting and extracting viral DNA from gingival crevicular fluid, whole saliva and parotid gland saliva.

Dental alterations associated with X-linked hypophosphatemic rickets.

The X-linked hypophosphatemic rickets is a rare metabolic disorder characterized by low serum phosphate levels caused by a decreased renal tubular reabsorption of inorganic phosphates. The initial complaints are a delay in the development of walking caused by deformity of the legs. Oral findings include poorly mineralized dentin, enlarged pulp chambers and root canals, and periradicular abscesses in caries-free teeth.

Oral metastasis of a hepatocellular carcinoma.

Hepatocellular carcinoma is a relatively common tumor that etiologically is closely linked to previous hepatitis B infection. Oral metastatic hepatocellular carcinoma is very rare, with only 61 cases reported in the literature.
