The aim of this study was to determine the prevalence of pain that is related to temporomandibular disorders (TMD), gender differences, and perceived treatment need in children and adolescents at a public dental clinic in Linköping, Sweden. A total of 862 children and adolescents aged 12 to 18 years received a questionnaire and their jaw opening was measured. Those who reported pain once a week or more in the masticatory system received a more comprehensive examination, including the Research Diagnostic Criteria for TMD and a neurologic examination (group 1). Group 2 reported pain less than once a week. Seven percent of subjects (63/862) were diagnosed with TMD pain. Both genders exhibited similar distributions of TMD diagnoses, except that myofascial pain was significantly more common in girls than in boys. Prevalence of pain once a week or more was reported as: 21% in the head; 12% in the temples; and 3% in the face, temporomandibular joint, or jaws. The prevalence of TMD-related ...

Objectives: This study was undertaken to observe the frequency of different diagnostic groups for temporomandibular disorders (TMDs) in patients who sought treatment for TMD in an outpatient clinic of a dental school. Methods: Files of patients who received a diagnosis of TMD in a period of 24 months were evaluated. Clinical and demographic data extracted from 213 patient files meeting the inclusion criteria were analyzed. Results: According to the classification of RDC/TMD, 100 patients were diagnosed with myofascial pain and 113 patients were diagnosed with disc displacement. Myofascial pain was the most common diagnosis among women; disc displacement with reduction (DDwR) was the most common diagnosis in men. Self-reported bruxism was reported by 59% of the patients. The amount of maximal mouth opening showed a statistically significant difference among patients with different clinical diagnoses and also between males and females (P<0.05). The mean visual analog scale (VAS) score was 4.9±2.4 in all diagnostic subgroups, and pain severity was higher in female patients but not significantly (P>0.05). Conclusion: Demographic characteristics of patients with TMD presenting to a dental school clinic in Ankara, Turkey were similar to those reported in the literature. A thorough anamnesis can provide more detailed information about parafunctional activity and sociodemographic factors and enhance accurate diagnosis.

Background The clinical examination in Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) is a strict procedure and comprise mandatory commands. However, learning and using these mandatory commands in general practice have proven to be difficult and their use of DC/TMD is minimal. Objectives To investigate if reliability on a diagnostic level for DC/TMD diagnoses differ between examiners using the mandatory commands or not. Methods Six examiners were divided into two groups: one using the mandatory commands in DC/TMD for the clinical examination and one that did not use the mandatory commands. A reliability assessment was performed twice, one occasion for each group of examiners. The assessment was performed according to the guidelines from the International Network for Orofacial Pain and Related Disorders Methodology. Each group of examiners thereby examined 16 subjects (11 TMD patients and 5 healthy individuals) each and the diagnostic agreement (reliability) as compared to diagnoses derived by a Reference Standard Examiner were calculated with Cohen' s Kappa coefficient. Results The DC/TMD diagnoses myalgia, arthralgia and headache attributed to TMD were included in the reliability assessment. There was no significant difference regarding diagnostic agreement reliability between the examiners using or not using the mandatory DC/TMD commands. Conclusions This study indicates that not using the mandatory commands in DC/TMD in general practice does not impair the diagnostic reliability regarding the diagnoses myalgia, arthralgia and headache attributed to TMD compared to including the commands.
Temporomandibular Disorders: Knowledge, Attitude and Practice among Dentists in Tehran, Iran
Journal of dental research, dental clinics, dental prospects, 2010
Temporomandibular disorders (TMD) account for the most common orofacial pains rising from musculoskeletal origin. The aim of this study was to investigate the level of knowledge, attitudes and practice of dental practitioners regarding TMD in Tehran, Iran. A questionnaire, containing 29 questions on etiology, signs and symptoms, diagnosis and treatment of TMD, was given to 200 randomly selected general dental practitioners and specialists as well as 11 TMD ex-perts. An overall response rate of 97% was achieved among participants (mean age: 39 ± 8.2 years old; mean years in practice: 11.5 ± 7.4). The mean score of knowledge of TMD was found to be 10.85± 2.54 (of a total of 23). TMD specialists were significantly more knowledgeable than general dental practitioners (p<0.05). With respect to attitude, there was a significant difference among various age groups, and by increasing age and years in practice, the attitude towards TMD had weakened. However, no significant difference was ...

Background Temporomandibular disorders (TMD) are a broad category of conditions arising from the various components of the temporomandibular joint complex. Bio-psychosocial model is the most accepted theory describing the etiopathogenesis of TMD. Dental students are vulnerable to psychological disorders, including anxiety, depression, and stress. Hence, the aim of the current study was to evaluate the prevalence and possible risk factors of TMD among dental students of various academic levels and explore the association of TMDs with demographic, academic, and psychosocial parameters. Methods A total of 246 students of a Saudi Arabia dental school were chosen for the study. After getting consent, all students were examined according to the Diagnostic Criteria for Temporomandibular Disorders, including Axis I and II components. Results The overall cross-sectional prevalence of TMD was found to be 36.99%. Pain arising from the jaw, temple, and the peri-auricular area were the most comm...

Background and aims. Temporomandibular disorders (TMDs) are the most common condition affecting the temporomandibular joint and associated structures. The aim of this study was the epidemiologic evaluation of TMDs and related factors in a group of Iranian adolescents. Materials and methods. This descriptive cross-sectional survey included a sample of 800 high school students (400 girls and 400 boys) aged 14 to18 years, in Mashhad, Iran, selected using cluster sampling. Examiners completed questionnaires and performed the clinical examinations. Data were analyzed with the Chi-square and Fisher exact tests. Results. The prevalence of TMDs in the studied sample was 34.7%. The most common signs of TMDs were clicking, muscle tenderness and TMJ tenderness. The most prevalent predisposing factors of TMDs were clenching, premature contact in protrusive movement and bruxism. A clear predominance was seen in girls (40.5%) compared with boys (29%) (P = 0.001). Conclusion. Signs and symptoms of TMDs were prevalent in Iranian adolescents with a clear female predominance.
Prevalence of temporomandibular dysfunction and pain in adult general practice patients

This study was carried out to determine the prevalence of temporomandibular joint (TMJ) dysfunction in mixed and permanent dentition and to evaluate the sex distribution in Turkish children. One hundred and eighty-two children with mixed dentition and 212 with permanent dentition were selected for the study, which used a questionnaire and clinical examination. Children with one or more signs (TMJ sounds, TMJ tenderness, muscle tenderness, restricted mouth opening) and/or symptoms (TMJ pain during mastication and mouth opening, restriction of the jaw opening and TMJ sounds) met the criterion of TMJ dysfunction. The total prevalence of signs and symptoms of TMJ dysfunction in the studied population was 68% (68% in girls and 68% in boys) in mixed dentition and 58% (61% in girls and 56% in boys) in permanent dentition. The Z-test and analysis of variance (ANOVA) were used for statistical analysis of the difference between the results. The total prevalence of signs and symptoms of TMJ dysfunction in mixed dentition was found to be higher than in permanent dentition (P < 0.05). N o statistically significant difference was found in the total prevalence of TMJ dysfunction between girls and boys.
