SUMARY: Insertion of the upper head of the lateral pterygoid (UHLP) in the temporomandibular joint disc (TMJ) has been linked to anterior displacement of the disc and temporomandibular disfunction. The aim of this study was to determine in human adults, the percentage of muscle fiber in the upper head of the lateral pterygoid muscle inserted in the articular disc. A systematic review of the lit...

Background and Purpose: Radiological findings were compared between the patients with osteoarthritis (OA) of temporomandibular joint (TMJ) and asymptomatic volunteers. Materials and Methods: OA was diagnosed in 16 patients (mean age 46.9, 69% women) with disc displacement. A second group consisted of 20 selected dental school students without any clinical signs or history of temporomandibular j...

X-rays and tomography, in their different modalities, are used as auxiliary diagnostic elements temporomandibular joint (TMJ) dysfunction, both static dynamic situations; however, because they only allow the observation of bone structures, magnetic resonance imaging (MRI) is ideal method to analyze, among other articular disc. Among internal disorders TMJ abnormal postural relationships between...

Supracondylar fractures of humerus in children are the most common pediatric elbow fractures that account for about 70% of elbow fractures [1-3]. These fractures are divided into two types; extension (98%) and flexion (2%) type. Regarding to the amount of displacement, the extension type is divided by Gartland into type I (without displacement), type II (with displacement but intact posterior c...

Diseases causing trismus or pain of the temporomandibular joint (TMJ) include temporomandibular joint disorders (TMJD), trauma, tumors and an inflammation. This report describes two cases of masticator space abscesses causing trismus and TMJ pain, which were initially diagnosed as TMJD. The first case was a 62-year-old female suffering from trismus and right-TMJ pain without swelling or redness...

The likelihood of development of degenerative joint disease (DJD) of the temporomandibular joint (TMJ) is related to the integrity of the TMJ disc. Predilection for mechanical failure of the TMJ disc may reflect inter-individual differences in TMJ loads. Nine females and eight males in each of normal TMJ disc position and bilateral disc displacement diagnostic groups consented to participate in...

A 35-year-old man was struck by a car on his right side and presented with paraparesis of both lower extremities. Radiographic examination revealed multiple transverse process fractures and anterior displacement of L5 on S1. Computed tomography revealed a bilateral anterior facet dislocation of the fifth lumbar vertebra on the sacrum. MRI showed rupture of the posterior ligamentous complex. A p...

Objectives: To determine the mean change in pain and mouth opening after intra-articular corticosteroid injection mixed with local anesthetic patients of temporomandibular joint internalderangement (disc displacement without reduction).Materials Methods: A Quasi-experimental study was conducted at Oral MaxillofacialSurgery Department, Armed Forces Institute Dentistry (AFID), Rawalpindi; from Fe...
