Clinical study of splint therapeutic efficacy for the relief of temporomandibular joint discomfort.

Purpose: This study aimed to evaluate the relationship between displacement of the mandibular condyle/disc due to occlusal splint insertion with splint therapy and changes in discomfort of the temporomandibular joint (TMJ), and to clarify the relationships between the outcomes over time of temporomandibular discomfort and TMJ magnetic resonance imaging (MRI) findings at the initiation of splint therapy.

Materials And Methods: A total of 75 patients admitted to hospital with discomfort around the TMJ were evaluated. A visual analogue scale for TMJ discomfort was administered during visits for approximately 3 months following the initiation of splint therapy.

Evaluation of the role of splint therapy in the treatment of temporomandibular joint pain on the basis of MRI evidence of altered disc position.

Objective: To clarify whether altering temporomandibular joint (TMJ) condyle and disc positions by occlusal splint (splint) therapy relieves TMJ pain and to determine whether splint therapy facilitates improvement of the ranges of condyle and articular disc motions.

Study Design: A total of 150 joints of 75 patients admitted with TMJ pain/discomfort were evaluated. A visual analog scale for TMJ pain was administered during visits following the start of splint treatment.

Diffuse large B-cell lymphoma of the mandible with periosteal reaction: a case report.

This report describes a rare case of a 63-year-old man with a lymphoma in the right mandibular ramus with periosteal reaction. Computed tomography (CT) images showed a soft tissue density (28 × 48 × 32 mm) around the right mandibular foramen. Bone-mode CT images showed diffuse bone destruction of the right mandibular ramus.

Contrast-enhanced multidetector computerized tomography for odontogenic cysts and cystic-appearing tumors of the jaws: is it useful?

Objective: The purpose of this study was to investigate the usefulness of computerized tomography (CT), particularly contrast-enhanced CT, in differentiation of jaw cysts and cystic-appearing tumors.

Study Design: We retrospectively analyzed contrast-enhanced CT images of 90 patients with odontogenic jaw cysts or cystic-appearing tumors. The lesion size and CT values were measured and the short axis to long axis (S/L) ratio, contrast enhancement (CE) ratio, and standard deviation ratio were calculated.

Movement of the mandibular condyle and articular disc on placement of an occlusal splint.

Objective: The aim of this study was to evaluate, with the use of magnetic resonance images, mandibular condyle and articular disc movement on occlusal splint application.

Study Design: Thirty-five subjects were classified into "Pain" and "No-pain" groups based on visual analog scale scoring of temporomandibular joint (TMJ) pain and were categorized as bilateral normal disc (ND), unilateral anterior disc displacement (ADD), or bilateral ADD position. t test and analysis of variance with multiple comparisons were used for statistical analyses.
