Idiopathic Bone Cavity: Clinicopathologic Features from a Case Series with Emphasis on Differential Diagnosis of Chronic Apical Periodontitis.

Introduction: Idiopathic bone cavity (IBC) is an uncommon bone lesion that usually affects youngsters as an unilocular radiolucency with predilection for the posterior mandible. Because the lesion is frequently located in proximity to the adjacent teeth, chronic apical periodontitis is commonly included as a differential diagnosis. The aim of the present study was to analyze the clinical and radiologic features of a series of IBCs diagnosed in a single service.

Oral myiasis in older adult with severe Alzheimer's disease.

Aims: Myiasis is a disease caused by the invasion of tissues by larvae of flies. The aim of this study was to carry out a review of reported cases of oral and maxillofacial myiasis in older adults and to show a case report of oral myiasis in a 95-year-old frail man with severe Alzheimer's disease from Brazil.

Methods And Results: Between 1988 and 2017, 35 oral and maxillofacial myiasis cases were reported in older adults in English-language studies from PubMed and Lilacs databases.

Oral perineurioma: clinicopathologic features from two cases and review of literature.

The present study reports two cases of oral perineuriomas, including a clinicopathologic review of the 39 published cases (17 intraneural and 22 extraneural perineuriomas) in the English language literature. In the first case, the tumor occurred in an 84-year-old male as a painless, asymptomatic, 20-mm submucosal nodule on the right lower mucobuccal fold near to the premolar area. In the second case, a 46-year-old female presented with a painless, 25-mm, slow-growing, fibrous, pedunculated nodule on the right buccal mucosa.

Clinicopathologic features, microvessel density, and immunohistochemical expression of ICAM-1 and VEGF in 15 cases of secondary syphilis with oral manifestations.

Background: Several studies have reported the clinical aspects of oral syphilis, but few papers have considered the involved immunoinflammatory mechanisms.

Objective: To analyze the clinicopathologic features and expression of immunoinflammatory and vascular proteins in oral secondary syphilis.

Study Design: Fifteen patients with oral secondary syphilis were included; histologic features were analyzed using hematoxylin-eosin-stained histologic slides and immunohistochemical reactions were performed against intercellular adhesion molecule 1 (ICAM-1), vascular endothelial growth factor (VEGF), and CD34.

Flies and the mouth.

Oral infections caused by flies are rarely encountered in clinical practice, and consequently, there is a paucity of information in the medical and dental literature about these conditions. In the present article, we present a concise review on oral myiasis or fly-blown disease. A variety of fly species can infest the oral tissues and produce an exotic clinical picture.

Segmental odontomaxillary dysplasia: report of a case emphasizing histopathological, immunohistochemical and scanning electron microscopic features.

Segmental odontomaxillary dysplasia (SOD) is a rare developmental disorder of the maxilla, and there is little information on its morphological features. Thus, the present article describes a case of SOD focusing on its histopathological, immunohistochemical and scanning electron microscopic features. Several dental abnormalities were present, including numerous dentin and pulp defects, altered composition of hard tissue, and proliferation of myofibroblasts in the pulp and the soft tissue surrounding affected teeth.

Lingual cortical mandibular bone depression: frequency and clinical-radiological features in a Brazilian population.

The aim of this study was to report the frequency and clinical-radiological features of cases of lingual cortical mandibular bone depressions (LCMBD) diagnosed in consecutive panoramic radiographs and cone-beam computed tomography (CBCT) scans from a Brazilian population. The methods included a retrospective analysis of consecutive panoramic radiographs, charts from the Oral Medicine clinic and consecutive CBCT scans. All cases diagnosed as LCMBD were selected and clinical-radiological data were retrieved from the clinical charts and by the analysis of the image exams.

Benign fibro-osseous lesions: clinicopathologic features from 143 cases diagnosed in an oral diagnosis setting.

Objective: The aim of this study was to report the clinicopathologic and radiologic features of 143 benign fibro-osseous lesions (BFOLs).

Study Design: Clinical and radiologic information were retrieved from the patients files, and histologic features were reviewed from hematoxylin and eosin-stained histologic slides.

Results: There were 22 ossifying fibromas (OFs), 21 fibrous dysplasias (FDs) and 100 osseous dysplasias (ODs; 65 florid, 18 focal, and 17 periapical).

Non-surgical management of paraesthesia and pain associated with endodontic sealer extrusion into the mandibular canal.

The aim of this report was to present a case of endodontic sealer extrusion into the mandibular canal in a 42-year-old woman. The patient was referred to the Endodontology and Stomatology Clinics, School of Dentistry, Estácio de Sá University, complaining of 5-day duration intense spontaneous pain and paraesthesia, both arising after an endodontic intervention. Conventional radiographs and computed tomography of the mandible showed the presence of radiopacities inside the right mandibular canal.

Comparative clinicopathological study of intraoral sebaceous hyperplasia and sebaceous adenoma.

Objective: The objective of this study was to compare the clinicopathological features of oral sebaceous hyperplasia and sebaceous adenoma.

Study Design: Clinical data, microscopical characteristics, and ki-67 immunoexpression were comparatively analyzed on 2 intraoral sebaceous adenomas, 6 intraoral sebaceous hyperplasias, and 21 normal intraoral sebaceous glands.

Results: Clinically, sebaceous glands presented as multiple separated papules, sebaceous hyperplasias as a single enlarged papule, and sebaceous adenoma as a well-defined nodule.

Regional odontodysplasia: morphological, ultrastructural, and immunohistochemical features of the affected teeth, connective tissue, and odontogenic remnants.

Purpose: Regional odontodysplasia (RO) is a rare developmental odontogenic defect. The affected teeth are described as "ghost teeth," due to malformation of dentin, enamel, and cementum. The purpose of this study was to describe the ultrastructural characteristics of the affected teeth as well as the immunohistochemical features of the soft tissue associated with 2 cases of regional odontodysplasia.

Fine-needle aspiration biopsy as an auxiliary diagnostic tool on intraoral minor salivary gland adenoid cystic carcinoma.

Background: Fine-needle aspiration biopsy (FNAB) is useful in diagnosis of major salivary gland adenoid cystic carcinoma (ACC), but it has been rarely reported on minor salivary gland ACC.

Objective: The aim of this study was to report the utility of FNAB on diagnosis of ACC involving minor salivary glands.

Study Design: Three patients presenting ACC involving the palate (2 cases) and buccal mucosa (1 case), with a mean age of 36 years and 2:1 female-to-male ratio, were included in the study.

Sarcoidosis presenting as gingival erosion in a patient under long-term clinical control.

Background: Sarcoidosis is an inflammatory granulomatous systemic disease that rarely affects the oral cavity. Gingival involvement has been reported in only a very limited number of cases, occasionally as the first manifestation of the disease. This article reports a case of sarcoidosis affecting the gingiva and alveolar mucosa in a patient previously treated for the systemic disease and considered under long-term clinical control.
