OBJECTIVE The aim of this investigation was to compare the pattern of temporomandibular disorder (TMD) diagnoses in clenching patients with different occlusal features, the null hypothesis being that no between-group differences exist. MATERIALS AND METHODS Two groups of subjects receiving a jaw clenching diagnosis and having large overjet or anterior open bite (Group A; N=45, 75.5% females, ...

INTRODUCTION To evaluate whether the hypothesis that estrogen levels are associated with temporomandibular disorders (TMD) in humans can be confirmed or contradicted by available literature. MATERIAL AND METHODS A systematic review based on the content of PubMed, Scopus, and Cochrane Library databases was performed. Studies were identified using a combination of key words 'temporomandibular d...

BACKGROUND Although third-molar extraction is common in the U.S., there are few reports on the relationship between third-molar extraction and temporomandibular disorder (TMD). The aim of this study was to investigate this potential association. METHODS The authors enrolled study subjects on their 15th birthdays and followed them continuously for a minimum of five years. The authors ascertain...

Sorting of membrane proteins between compartments of the secretory pathway is mediated in part by their transmembrane domains (TMDs). In animal cells, TMD length is a major factor in Golgi retention. In yeast, the role of TMD signals is less clear; it has been proposed that membrane proteins travel by default to the vacuole, and are prevented from doing so by cytoplasmic signals. We have invest...

Background Temporomandibular disorder (TMD) represents a subgroup of painful orofacial disorders involving pain in the temporomandibular joint (TMJ) region, fatigue of the cranio-cervico-facial muscles (especially masticatory muscles), limitation of mandible movement, and the presence of a clicking sound in the TMJ. TMD is associated with multiple factors and systemic diseases. This study aimed...

AIMS To evaluate the prevalence of different Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) diagnoses in a population of patients seeking for TMD treatment at a tertiary clinic in Northern Italy; to evaluate the pattern of age distribution of RDC/TMD diagnoses and to compare data with those from similar studies in the literature. MATERIALS AND METHODS Two-hundred-forty...

AIMS The present study was designed to test the hypothesis that dental occlusion may have a role in mediating the effects of bruxism in temporomandibular disorders (TMD) patients. It aimed to answer the clinical research question: in a population of TMD patients with clinically diagnosed clenching-type bruxism, are the different TMD diagnoses associated with different occlusal features? MATER...

In-plane transition-metal dichalcogenides (TMDs) quantum wells have been studied on the basis of first-principles density functional calculations to reveal how to control the electronic structures and the properties. In collection of quantum confinement, strain and intrinsic electric field, TMD quantum wells offer a diverse of exciting new physics. The band gap can be continuously reduced ascri...

background and objectives : temporomandibular disorder (tmd) refers to chronic pain of the temporomandibular joint (tmj) associated with headache, neck pain, shoulder pain or back pain. the origin of these pains may be related to tmd. many patients with chronic headache undergo different treatments for long periods of time with no cure. these headaches can be treated with proper diagnosis. this...
