Histological assessment of a novel de-epithelialization method for connective tissue grafts harvested from the palate. An experimental study in cadavers.

Objectives: This study aims to compare the histological outcomes of three distinct de-epithelialization methods used in (connective tissue grafts) CTG harvested from the palate.

Materials And Methods: An experimental study using nine cadaver head specimens was carried out to compare 3 different de-epithelialization techniques for CTG. Eighteen samples were randomly allocated to three study groups: bone scraper, diamond bur and extraoral removal with a scalpel.

Gingival lymphatic malformation. An atypical case report.

Lymphatic malformations are a rare pathology that presents a highly variable clinical expression. Intraorally, it mainly affects the dorsum of the tongue. The objective of this work is to present a case of lymphatic malformation in an atypical location.

Non-infectious granulomatous disorders of the upper lip: clinicopathological analysis of 11 patients.

Background: Non-infectious granulomatous disorders of the upper lip represent a special chapter of oral and maxillofacial pathology. In this work we report a case-series of this process, to analyse its main clinicopathological features and find differential data that allow us improve its diagnosis and understand its pathogenesis.

Methods: We present 11 cases of non-infectious granulomatous disorders of the upper lip, 8 women and 3 men with an age range of 29-84 years, who have been attended at the Oral Medicine Department of the IUCT (France) and the Oral Medicine Unit of the UPV/EHU (Spain).

Peripheral giant cell granuloma associated with a dental implant: A case report.

Peripheral giant cell granuloma (PGCG) is a reactive exophytic lesion classified as a benign tumor of the oral mucosa. Although its etiology is not clear, it may be a consequence of local chronic irritation or persistent trauma. The objective of this case report was to document the main clinical and histopathological characteristics of a patient with a PGCG associated with a dental implant.

Central odontogenic fibroma: an international multicentric study of 62 cases.

Objective: The aim of this study was to report the clinicopathologic features of 62 cases of central odontogenic fibroma (COdF).

Study Design: Clinical and radiographic data were collected from the records of 13 oral pathology laboratories. All cases were microscopically reviewed, considering the current World Health Organization classification of tumors and were classified according to histopathologic features.

Therapeutic management of the odontogenic keratocyst. An energetic approach with a conservative perspective and review of the current therapeutic options.

Background: Odontogenic keratocysts (OKC) are cystic lesions appearing in the jaws, usually asymptomatic with a progressive growth into the bone. Many of them are diagnosed by a routine radiological examination.

Material And Methods: This study reports a 12-year-old girl that presented an asymptomatic large radiolucent unilocular lesion associated to the crown of 3.

Angina bullosa hemorrhagica, an uncommon oral disorder. Report of 4 cases.

Angina bullosa hemorrhagica (ABH) is a rare oral disorder characterized by blood-filled bullous lesions in the oral cavity and the oropharynx in the absence of an underlying systemic, haematological or mucocutaneous condition. The presentation of the lesions is acute and located on the lining mucosa, mainly on the soft palate. Often, these lesions are single and rupture easily leaving an ulcerated area.

Detection of Microparticles of Different Origins in Implant Prostheses and Abutments.

Purpose: To assess whether particles from metal and other alloplastic materials detected in tissues surrounding dental implants could have other sources of origin besides biotribocorrosion or detachment from the implant surface.

Materials And Methods: A total of 52 prostheses were randomly tested at various stages of manufacture. Identification of the detached microparticles was performed using light field microscopy and comparison with previously obtained microscopic images.

Characterization of juvenile spongiotic gingival hyperplasia as an entity of odontogenic origin.

Background: Juvenile spongiotic gingival hyperplasia (JSGH) is a distinct clinicopathological entity of the buccal gingiva of young patients which has been related to several factors such as plaque formation, hormonal modifications, and viral infections; however, its true etiopathogenesis remains unsolved. Several immunohistochemical studies have demonstrated the similarity between the junctional epithelium (JE) and the hyperplasic epithelium of JSGH. The objective of this study is to analyze the clinicopathological and immunohistochemical characteristics of JSGH to explain its origin.

Inflammatory fibro-epithelial hyperplasia related to a fixed implant-supported prosthesis: A case report.

The gingival overgrowth is a common finding in the clinical practice with a diverse etiology. There are no treatment guidelines defined for this oral lesions. These can provoke discomfort to the patient and often, can alter the function of the stomatologic system.

Maxillary peripheral keratocystic odontogenic tumor. A clinical case report.

The keratocystic odontogenic tumor is a benign odontogenic cystic neoplasia characterized by its thin, squamous epithelium with superficial parakeratosis. It has the potential for infiltration and local aggressiveness and has a high rate of recurrence. This neoplasia is predominantly found in males and people of white origin.
