o bjectives: temporomandibular dysfunction (tmd) is a group of disorders in the facial region and temporomandibular joint (tmj). biomarkers are assumed to play a role in pain and early detection of destruction. the aim of this study was to compare the saliva and serum antioxidant levels in patients with tmd and healthy subjects. mat erials and methods : this case-control study was conducted on ...

BACKGROUND Associations between temporomandibular disorder (TMD) and psychological variables, pain conditions, and daily activities have been reported more commonly in middle-aged individuals than in children. However, to determine factor-specific preventive programs for TMD, it is important to evaluate the associations between multiple factors and TMD symptoms during childhood. The aim of this...

The aims of the study were to determine the impact of temporomandibular disorders (TMD) on self-percieved oral health related quality of life (OHRQoL) and to compare OHRQoL of patients with TMD with a control group. A total of 81 TMD patients participated in a study group and 400 adults served as the control group. The mean OHIP summary scores were computed for all patients with the same diagno...

UNLABELLED The aim of this study was to assess the prevalence of temporomandibular disorders (tmd) in schizophrenic patients compared with control patients. PATIENTS AND METHODS 50 schizophrenic patients attended in the Psychiatric Unit at the Virgen Macarena Universitary Hospital of Seville were compared with 50 control patients (without systemic diseases, and drugs) attended in the School o...

OBJECTIVES Temporomandibular dysfunction (TMD) is a group of disorders in the facial region and temporomandibular joint (TMJ). Biomarkers are assumed to play a role in pain and early detection of destruction. The aim of this study was to compare the saliva and serum antioxidant levels in patients with TMD and healthy subjects. MATERIALS AND METHODS This case-control study was conducted on 28 ...

Many researches have focused on the optimal design of tuned mass damper (TMD) system without the effect of soil–structure interaction (SSI), so that ignoring the effect of SSI may lead to an undesirable and unrealistic design of TMD. Furthermore, many optimization criteria have been proposed for the optinal design of the TMD system. Hence, the main aim of this study is to compare different opti...

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...

this study is investigated the optimum parameters for a tuned mass damper (tmd) under the seismic excitation. shuffled complex evolution (sce) is a meta-heuristic optimization method which is used to find the optimum damping and tuning frequency ratio for a tmd. the efficiency of the tmd is evaluated by decreasing the structural displacement dynamic magnification factor (ddmf) and acceleration ...

The theory behind small amplitude movement of a single pendulum is stated, followed by the construction of a simple example of a coupled pendulum with two degrees of freedom including the unidirectional movement of the structure and the pendulum angle in relation to vertical. These models and the finite elements software SAP 2000 are also applied to a single and to a multiple degree of freedom ...

abstract: appealing to the principle of vertical residence and stemming the horizontal expansion of the city, the tehran milad tower is being built on 35000 sm3 site with the total area of 220000 sm3. with a height of over 170m, this 56-story concrete building is in the final stages of construction and would be the highest residential building of iran. since tehran is located in a high-risk ear...
