Whole-exome sequencing and copy number alterations analysis in a case of expansive florid cemento-osseous dysplasia.

Unlabelled: Whole-exome sequencing (WES) analysis of an expansive case florid cemento-osseus dysplasia were reported for the first time. Also, the new potential candidate genes were reported to expand our knowledge about their molecular pathogenesis.

Abstract: We report a case of expansive florid cemento-osseus dysplasia in a 32-year-old female patient who presented an expansive tumoral lesion in the anterior mandible.

Lymphomas affecting the submandibular glands.

Background: Lymphomas affecting the submandibular glands are very uncommon and few reports are currently available in the literature. Therefore, the aim of the current study is to describe the clinical and microscopic features of an original series of lymphomas affecting the submandibular glands.

Material And Methods: The pathology files of two institutions were searched for lymphoma cases affecting the submandibular glands.

Efficacy of gastric aspiration to reduce postoperative vomiting after orthognathic surgery: double-blind randomised clinical trial.

Orthognathic surgery is a treatment modality indicated to correct dentofacial deformities. Postoperative vomiting can be associated with multifactorial origin mainly correlated to patient-related symptoms, anaesthetic and surgical factors. Swallowed blood has been related to one of those multifactorial vomiting causes.

Desmoplastic fibroblastoma (collagenous fibroma) of the oral cavity.

Unlabelled: Desmoplastic fibroblastoma is benign soft tissue tumor, with fibroblastic or myofibroblastic origin, that rarely occurs in oral cavity. We reported the case of a 56-year-old man who presented a tumor in the left mandibular alveolar ridge, with slow and asymptomatic growth, with no osseous involvement. The tumor was sessile with lobulated surface, covered by healthy mucosa with erythematous areas.

Prescribing errors in antibiotic prophylaxis by dentists in a large Brazilian city.

Prescribing errors may contribute to antibiotic resistance and other drug-related problems. To investigate the quality of prescriptions involving antibiotic prophylaxis by dentists in a large Brazilian city, 366 dental prescriptions were randomly selected from 31,105. A prophylaxis indication represented 24.

Ossifying odontogenic fibroma: A rare case report.

Odontogenic fibroma (OF) is a rare benign odontogenic neoplasm that is most commonly found in the mandibular/premolar region of female patients in the second to fourth decades of life. Well-defined radiolucent lesions that may induce root resorption are normally observed. Rare variants of OF have been described in the prior literature, including references to: 1) giant cell lesions, 2) amyloid-like protein deposition, and 3) ossifying variants.

Gossypiboma in the oral region: Case report and literature review.

Gossypiboma is an inflammatory reaction to a foreign body, specifically composed of a cotton matrix left behind after surgery. The present study aims to present a case report of gossypiboma 23 years after a dental surgery and to make a literature review of the English language cases published on the issue. A 42-year-old woman was attended to evaluate complaints of pain on the right side of the maxilla.

Diffuse large B-cell lymphoma, not otherwise specified of the palate: A case report.

Diffuse large B-cell lymphoma (DLBCL) is the most frequent type of non-Hodgkin´s lymphoma found in oral and maxillofacial regions. A large number of cases may be biologically heterogeneous, which are commonly defined as DLBCL, not otherwise specified (NOS) by the World Health Organization (WHO-2008). The present case reports on an ulcer of raised and irregular edges, found on the border between the hard and soft palate, as the first and only manifestation of an extranodal non-Hodgkin lymphoma in an 85-year-old patient.

Sequential supernumerary teeth in nonsyndromic patients: report of 3 cases.

Supernumerary tooth/teeth (ST) are a well recognized clinical phenomenon defined as teeth that are additional to the normal complement. The purpose of this report was to describe 3 patients who developed multiple sequential ST. All patients were boys between 8 and 12 years old without significant medical history.
