Disagreement exists regarding the relationship between occlusal interferences and temporomandibular joint dysfunction (TMD). This study sought to determine how a balanced occlusion, providing uniform contact in centric relation, would affect signs and symptoms of TMD. A randomly chosen group of 60 patients with occlusal interferences and signs and symptoms of TMD used a mandibular orthotic to b...

Purpose Whiplash injury can cause internal derangement of the temporomandibular joint (TMJ) and lead to temporomandibular disorders (TMDs). Our aim was to evaluate whether the initial clinical findings in TMD patients with whiplash injury are correlated with their magnetic resonance imaging (MRI) characteristics. Materials and methods This case-control study involved 219 patients (135 women, ...

BACKGROUND To evaluate the EMG activity and thickness of right masseter (RM), left masseter (LM), right temporal (RT) and left temporal (LT) muscles and bite force in children with temporomandibular disorders (TMD). MATERIAL AND METHODS Forty five children (mean age 8.8 years; 22 boys and 23 girls) were examined on the basis of the RDC/TMD and the Faces Pain Scale-Revised (FPS-R) was used to ...

Methods: Case-control design. The sample comprised 103 subjects, males and females from 19 to 54 year-old, which were divided into two groups: Group 1 (control) without TMD (n=52) and Group 2 (cases) with TMD (n=51). Inclusion criteria for Group 2 were based on axis I of the RDC/TMD protocol. Two calibrated examiners (Cohen kappa = 0.85) performed the clinical examination to collect data on occ...

Proteolytic processing of the amyloid precursor protein by beta-secretase generates C99, which subsequently is cleaved by gamma-secretase, yielding the amyloid beta peptide (A beta). This gamma-cleavage occurs within the transmembrane domain (TMD) of C99 and is similar to the intramembrane cleavage of Notch. However, Notch and C99 differ in their site of intramembrane cleavage. The main gamma-c...

OBJECTIVE To verify whether headaches (HAs) are associated with temporomandibular disorders (TMD) in young Brazilian adolescents. METHODS From a population sample, 3117 public school children (12 to 14 y) were randomly invited to participate in this study. TMD was assessed according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) Axis I, in addition to questions ...

OBJECTIVES Temporomandibular joint disorders (TMD) are often associated with aural manifestations. However, it is not clear whether aural fullness could be induced by TMD. The purpose was to investigate the TMD and effectiveness of TMD treatments in patients with mainly or exclusively aural fullness complaint. METHODS One hundred and twelve patients, who had aural fullness as the main or sole...
