Abstract:Aim
The aim of this study was to define the prevalence and severity of temporomandibular disorders (TMD) among Iranian dental and nondental students who attended Shiraz University of Medical Sciences.
Materials and methods
The samples consisted of 200 subjects, 100 dental and 100 nondental students (equal distribution between males and females). Subjects ages ranged from 18 to 30 years (24.07 ± 2.93). A functional evaluation was performed using the Helkimo dysfunction index (Di). Data were evaluated by the C… Show more

The overall prevalence of TMD symptoms in the population studied was 77.2%, with female preponderance of TMD symptoms (83%). This is higher than the estimated prevalence (23%) in the Australian general population.

“…7,10,13 Many studies in other universities concluded that TMD is higher among medical students than other disciplines. 7,12,13,17 Hence, the aim of the current study was to assess the prevalence and severity of TMD among undergraduate medical students and to compare the severity of TMD between them in the presence of parafunctional habits, such as khat chewing.…”
Introduction:The aim of this study was to assess the prevalence and severity of temporomandibular joint disorders (TMDs) among undergraduate medical students in the presence of khat chewing over a period of time.
Materials and methods:Totally, 186 medical college students (age ≤ 20 years) were randomly selected for the present study. The study subjects were divided into two groups according to age, under 20 and above 20 years. The study was based on Fonseca's anamnestic index and its questionnaire, which is composed of 10 questions and classifies the severity of TMDs. The obtained data were coded and entered into Statistical Package for the Social Sciences (SPSS) program for analysis using chi-square test at significance level of 5%.
Results:Most of the participants were male (68.8%) students and older than 20 years (63% Corresponding Author: Mohammed M Al Moaleem, Department of Prosthetics, College of Dentistry, Jazan University, Jazan Kingdom of Saudi Arabia, e-mail: drmoaleem2014@gmail.com comprised 31.7%. From the total samples, only 38.0% was classified as having mild TMD and 0.50% were classified as having severe TMD. Poor dental articulation, grinding of teeth, headaches, tense personalities, and temporomandibular joint (TMJ) clicking were the most common clinical findings. The mean scores showed no significant difference among gender (p ≤ 0.29) and the khat chewing (p ≤ 0.531) groups for the 10 questions. However, it showed significant difference among age groups (p ≤ 0.025).
Conclusion:The majority of subjects complained of mild TMD, while only a few cases showed a moderate TMD among different age groups. The most frequently reported dysfunctions were related to poor dental articulation and grinding of the teeth, frequent headaches, the clicking of joint, and tense personalities. No significant difference was found between gender and khat and nonkhat chewing groups.Clinical significance: Khat chewing is a parafunctional habit and affects dental occlusion (especially cuspal wear) in terms of anterior guidance. Such alterations in occlusion are known to be one of the causative (predisposing) factors of TMD.
“…In a literature search, we found a few reports addressing the epidemiology of TMD in the Middle East, among which only a single study was found in a Jordanian population; however, it lacked the use of a standard protocol . Therefore, the present study was designed to document the prevalence of TMD signs and symptoms and potential correlations in a Northern Jordanian sample of participants using the DC/TMD protocol as the first of its kind in Jordan.…”
Aim:The aim of the present study was to document the prevalence and possible correlations of temporomandibular disorders (TMD) in a sample of participants from Northern Jordan.
Methods:A total of 368 adult participants were consecutively selected from visitors to a major health facility in Northern Jordan and examined according to the diagnostic criteria (DC) for TMD (DC/TMD) protocol. Patients with conditions that could interfere with TMD diagnosis were excluded. Pearson correlation and analysis of variance statistical tests were applied. Statistical significance was set at P ≤ 0.05, with a 95% confidence interval.Results: A total of 98 patients (26.7%) had 1 TMD diagnoses; 60 participants (16.3%) had a pain-related TMD diagnosis, 48 (13%) had intra-articular joint disorders (IAD), and 16 had both pain-related TMD and IAD. In addition, six (1.6%) participants were found to have degenerative joint disease. Females were found to have a higher prevalence of pain-related TMD diagnoses (r = 0.111, P = 0.034) and headache (r = 0.129, P = 0.013) than males. Clicking was positively related to both pain-related TMD (r = 0.154, P = 0.003) and IAD (r = 0.576, P = 0.000).
Conclusion: The frequency of TMD and related features was reported in a NorthernJordanian population using DC/TMD for the first time, and the results are comparable to other populations in similar study settings.
