Extensive cervical necrotizing fasciitis of odontogenic origin.

Necrotizing fasciitis (NF) is an uncommon infection, but potentially lethal, especially when associated with systemic disorders such as diabetes. The authors report a case of necrotizing fasciitis from odontogenic origin in a patient with uncontrolled diabetes mellitus. The initial diagnosis was based on clinical information, in which multiple necrosis areas in cervical and thoracic regions were observed.

Tooth embedded in lower lip following dentoalveolar trauma: case report and literature review.

One of the most frequent consequences of trauma to the maxillofacial region is damage to teeth and supporting structures. Such damage can occur either in isolation or in conjunction with other fractures and soft tissue lacerations. In emergency situations, the harm caused to teeth could go unnoticed during the clinical examination, depending on the nature and complexity of the trauma and the primary care team's awareness of orofacial injuries.

Cytotoxicity testing of methyl and ethyl 2-cyanoacrylate using direct contact assay on osteoblast cell cultures.

Purpose: Cyanoacrylate has been used as a commercial tissue adhesive. Recently, ethyl 2-cyanoacrylate has been suggested for the fixation of onlay autogenous bone graft. However, ethyl 2-cyanoacrylate must be biocompatible with bone tissue.

Mandibular angle fracture treated with new three-dimensional grid miniplate.

Fractures of the mandibular angle deserve particular attention because they represent the highest percentage of mandibular fractures and have the highest postsurgical complication rate, making them the most challenging and unpredictable mandibular fractures to treat. Despite the evolution in the treatment of maxillofacial trauma and fixation methods, no single treatment modality has been revealed to be ideal for mandibular angle fractures. Several methods of internal fixation have been studied with great variation in complications rates, especially postoperative infections.

Immunohistochemical, tomographic, and histological study on onlay bone graft remodeling. Part III: allografts.

Objective: In the last decades aroused the interest for bone tissue bank as an alternative to autogenous grafting, avoiding donor sites morbidity, surgical time, and costs reduction. The purpose of the study was to compare allografts (ALg) with autografts (AUg) using histology, immunochemistry, and tomographic analysis.

Material And Methods: Fifty-six New Zealand White rabbits were submitted to surgical procedures.

Foreign body ingestion during dental implant procedures.

Two cases of swallowing of foreign material related to dental implants during dental practice are described. A conservative approach by clinical-radiographic follow-up was performed in both cases; however, one of the patients required colonoscopy under general anesthesia for the removal of the impacted foreign body from the intestinal region. These complications not only have associated economic cost but also carry the risk of malpractice litigation against the professional; thus, the surgeon was responsible for all the costs of hospital and surgery management of this case.

Guided surgery in unusual palatal torus.

Palatine torus is a benign congenital outgrowth of bone that affects the hard palate and palatine processes, resulting from the "overworking" of osteoblasts and bone deposition along the line of the palatine fusion. Surgical excision is the only treatment for torus, and such patients are susceptible to intraoperative and postoperative complications of a traumatic, functional, or infectious nature. This article describes an atypical case of torus palatinus measuring 20.

Brain abscess of odontogenic origin.

Brain abscess is a rare and threatening infection, which is in a suppuration area, caused either by trauma, neurosurgical complication, or by a secondary infection of dental origin complication. The infectious process spread from the start focus can occur in 2 ways: hematogenous or by contiguity. The treatment should ideally be based on the etiological factor excision, combined with drainage and antibiotics as adjuvant; this philosophy is not observed in the reports described in the 1960s, 1970s, and 1980s.

Oral and maxillofacial myiasis: a case series and literature review.
