BACKGROUND: Despite substantial displacements, fractures of the mandibular condyle rarely lead to necrosis. This illustrates the negligible role of the inferior alveolar artery in intraosseous supply to the condyle, and led to this systematization of its arterial vascularization. METHODS: Forty-two temporomandibular joints from nonembalmed cadaveric specimens were studied following injection of latex (n = 32) or India ink (n = 10). RESULTS: The intraosseous branches of the inferior alveolar artery that lead to the condyle were inconstant and often rudimentary...

Crown-root fracture is one of the most challenging fracture types in the dental traumatology literature. Traumatized anterior teeth require quick functional and esthetic repair. In the case of a complex crown fracture of the maxillary left central incisor, requiring endodontic treatment, a fiber-reinforced post was used to create a central support stump to restore the dental morphology. This report describes the clinical procedures involved in the treatment. After two years of follow-up, the clinical and radiographic findings demonstrated that the adopted clinical protocol was successful and yielded healthy periodontal tissues with no signs of periradicular pathology...

Prognosis of a horizontal mid-root fracture is favorable, primarily because the dental pulp tends to maintain its vitality and the fracture segments are completely intraalveolar. Healing usually occurs with deposition of calcified tissue. However, if the segment coronal to the fracture becomes nonvital and infected, healing occurs by interposition of granulation tissue. This report describes a case of a horizontal mid-root fracture in a right maxillary central incisor tooth, where the apical fractured segment was significantly displaced in a linear direction...

A 13-year-old female presented with traumatized maxillary central incisors that had been endodontically treated. Five years later, at a different dental office, she had the clinical crowns removed, leaving subgingival margins. From the patient's history and our initial assessment, it seemed as if the teeth had been fractured and luxated but not avulsed. Endodontic posts with spot-welded orthodontic brackets were temporarily cemented to enable orthodontic extrusion. Once access to restorable margins was obtained, the temporary posts were removed and conventional fiber posts with interim composite crowns were placed...

Introduction: The circumferential 2 mm ferrule during the fabrication of the crown is strongly advocated for the long-term clinical success. During the routine clinical practice, the dentist encounters the endodontically treated tooth (ETT) with inadequacy of the ferrule in some segment due to caries, abrasion, and erosions. The aim of this in vitro study was to investigate the consequence of inadequate segmental ferrule location on fracture strength of the root canal-treated anterior and posterior teeth...

Facial fracture management dates as early as Hippocratic era. Comminuted mandibular fractures are one of the challenging clinical condition requiring high surgical expertise to achieve a good functional and esthetic outcome. In presence of infection and other facial fractures managing comminuted mandibular fracture becomes more challenging. Here we present a case of grossly comminuted and infected mandibular fracture with delayed presentation managed by using maxillary distractor as stabilizing agent. Using a maxillary distractor for managing a fractured mandible has been seldom reported in literature...
