Examination for the Factors Involving to Joint Effusion in Patients with Temporomandibular Disorders Using Magnetic Resonance Imaging.

Background: This study investigated the factors involving joint effusion in patients with temporomandibular disorders.

Methods: The magnetic resonance images of 131 temporomandibular joints (TMJs) of patients with temporomandibular disorders were evaluated. Gender, age, disease classification, duration of manifestation, muscle pain, TMJ pain, jaw opening disturbance, disc displacement with and without reduction, deformation of the articular disc, deformation of bone, and joint effusion were investigated.

Odontogenic Infection Pathway to the Parapharyngeal Space: CT Imaging Assessment.

Introduction: Parapharyngeal space infection may lead to severe and potentially life-threatening complications. The aim of this study was to assess the odontogenic infection pathway to the parapharyngeal space using CT imaging.

Materials And Methods: Nineteen patients in mandibular odontogenic infections with abscess who underwent contrast-enhanced CT were evaluated in this study.

Diagnosis of root fractures using cone-beam computed tomography: difference of vertical and horizontal root fracture.

Objectives: The aim of this study was to investigate the occurrence of vertical and horizontal root fractures using cone-beam computed tomography (CBCT).

Methods: We reviewed the CBCT images of 51 patients who were examined by CBCT for the diagnosis of root fracture. The occurrences of vertical and horizontal root fractures were investigated concerning the pulpal vitality and the kind of tooth, and analyzed by cross-tabulation.

Forming temperature of ethylene vinyl acetate sheets for fabrication of vacuum-formed mouthguards.

Background/aims: The appropriate heating temperature for the fabrication of mouthguards using ethylene vinyl acetate sheets is reported to be 80-120°C. However, the measurement side of the heating temperature has not been determined. The aim of this study was to investigate the influence of the measurement side of the heating temperature when fabricating mouthguards.
