Background: Teeth with severe crown destruction and endodontically treated may or may not present a circular strip of dental tissue located in the cervical region called ferrule.
Aims: The aims of this study were to evaluate ferrule thickness influence on endodontically treated teeth (ETT) resistance to fracture.
Materials And Methods: A total of 30 bovine incisor teeth were selected, endodontically treated and randomly distributed, according to the ferrule thickness: G1- no ferrule, G2 - 1 mm, and G3 - 2 mm.
Article Synopsis
- The report discusses a clinical case of oral lichenoid lesions linked to amalgam dental restorations, accompanied by desquamative gingivitis, over a nine-month follow-up period.
- Diagnosis was achieved through a combination of medical history, clinical examination, histopathology, and positive patch tests for allergies, specifically to thimerosal, a mercury compound.
- Improvements were noted after replacing amalgam restorations, including the reduction of desquamative gingivitis and erosive lesions, yet ongoing observation is necessary to rule out possible underlying conditions like lichen planus.
Reestablishing blood flow and allowing the continuation of root development are some of the objectives of pulp revascularization. This procedure is currently indicated for teeth with incomplete root formation as an alternative to the traditional treatment of apecification, which consists of inserting calcium hydroxide paste into the root canal for a determined time period in order to induce the formation of a calcified barrier. Although it is considered as the most classically employed therapy, the permanence of the paste for long time periods may lead to the weakening of the root due to hygroscopic properties, as well as proteolytic activities of calcium hydroxide.

Background Data: PDT is a technique that utilizes light to activate photosensitizers in the presence of oxygen to produce reactive radicals.
Materials And Methods: A culture medium of 1% glucose, 2% sucrose, 1% young primary culture of L.
Malignant peripheral nerve sheath tumor is a malignant neoplasm that is rarely found in the oral cavity. About 50% of this tumor occurs in patients with neurofibromatosis type I and comprises approximately 10% of all soft tissue sarcomas of head and neck region. Intraosseous malignant peripheral nerve sheath tumor of the maxilla is rare.

Literature Review: Stem cells seem to be present in many other tissues than researchers had once thought; and in some specific sites they can be easily collected, without the need of expensive interventions. The oral cavity is one of these regions where their collection can be accomplished, with plenty of accessible sites enriched with these precious cells.
Detection of vertical root fractures in endodontically treated teeth in the absence and in the presence of metal post by cone-beam computed tomography.
BMC Oral Health
April 2016
Background: Aim of this study was to investigate the influence of gutta-percha and metallic posts on the efficiency of Cone Beam Computed Tomography (CBCT) in diagnosing Vertical Root Fracture (VRF).
Methods: Forty-eight teeth were divided into 3 experimental and 3 control groups. The teeth of the first experimental group and the first control group received neither gutta-percha nor metal posts.
