Magnetic resonance imaging in patients with internal derangement of TMJ compared with clinical diagnosis and surgical findings

The aim of this study is to compare the provisional diagnosis based on an initial clinical examination with subsequent findings of the magnetic resonance imaging and the surgical findings in patients with internal derangement of the temporomandibular joint

Evaluation of transosseous wiring versus screw-wire osteosynthesis in treatment of mandibular fractures

From this study, it was concluded that, screw-wire osteosynthesis is well tolerated and provides satisfactory mechanical stability of fixation in mandibular fractures. It has an area contact and can not be loosen quickly when compared with wire osteosynthesis. It is possible to treat most of mandibular fracture utilizing internal fixation with screw-wire osteosynthesis, especially when plating system is not the technique of choice, and the case is unfavorable mandibular fracture

effect of actinomycin [D] on healing of extraction stocket, clinico-experimental study

Administration of actinomycin "D" one or two weeks before extraction leads to retardation of healing. In general, the retardation of healing is even tolerable if compared with cancer chemotherapy as life saving measure or even effective treatment for the patient. However, it was recommended that patients undergoing chemotherapy should be seen by the oral surgeon before starting chemotherapeutic treatment for dental services and if possible, it is advisable to postpond the chemotherapy for at least 7 to 10 days after the extraction to allow primary epithelialization of the wound

Comparison between the healing of autogenous and heterogenous bone grafts [experimental study]

In the present study, 12 male adult dogs were randomly divided into two groups, each consisting of six dogs. Surgical bone defect was created in the inferior border of the mandible. For the first group, the defects received rib autogenous graft, and Kiel bone was placed in the second group. Histological sections, using H and E stain, were performed after each sacrifice of the 2 animals at 6-, 12- and 24-week intervals [two specimens at each interval]. The results were successful and promising with autogenous and heterogenous grafts. However, Kiel bone had higher advantages, besides high osteogenic potential in terms of eliminating a second operation, as in autografts, as well as time saving, ready availability, with ease of the shape selection
