Material and Methods: It was a cross sectional analytical study based on Fonseca’s Questionnaire. Results: The sample consisted of 225 participants, 118 of them were men (52.4%) and 107 of them were women (47.6%), with an average age of 37.99 ± 12.05 years old. Almost all of the samples (92%) informed that they did not have a difculty in mouth opening and moving the jaw to the sides (92%), 84% reported no clenching teeth and 80% reported no articulation disorders. While 34.8% of respondents reported muscular pain during mastication and 38.7% reported sufering from frequent headaches occasionally. of respondents reported muscular pain during mastication and 38.7% reported sufering from frequent headaches occasionally. Temporomandibular Joints (TMJ) clicking was reported among 13.3% of participants and only a very small number of samples (4.9%) reported pain in the temporomandibular joint. Conclusion: The prevalence of TMD was quite high i.e 50.7%. In term of severity, most of subjects had mild TMD’s (86.8%). The sociodemographic factors that signifcantly associated with severity of TMD were education and work status.

DOI: 10.15562/jdmfs.v5i2.1074 The prevalence of Temporomandibular Disorder (TMD) and its severity among YARSI University Employees Helwiah Umniyati * Introduction Temporomandibular joint disorders (TMD) describe as a number of related disorders that afect the temporomandibular joints (TMJ) and its associated muscles. ligaments, as well as dental occlusion. 1 Te prevalence of TMD varied from 9.8 to 80 percent and these problems are very common amongst age of 20-50 years, especially in women. 2 In Brazilian study, Goncalves et al. 3 found that the prevalence of TMD was 39.2%. 3 More than half of population in the world (60-70%) have at least one of the symptoms of TMD in their lives, but very few of them seek treatment which is about 5%. 4 Signs and symptoms of TMJ disorders are pain in the jaw, difculty swallowing or discomfort when swallow- ing, clicking or crepitation of the TMJs, limited jaw opening capacity and deviation in the movement patterns of the mandible, clicking or crepitation of the TMJs, jaw locked, headaches, uncomfortable bites, premature contact, and masticatory disor- ders. 5,6 Te etiology of TMD’s involves several components which may work independently or together. Tese factors include genetics, stress, tooth occlusion changes, muscular dysfunction and systemic conditions that may manifest in the temporomandibular joint. 6 TMD are more preva- lence in age 20-45 years, with more females sufer- ing TMD’s than males. 7 To measure the severity of TMD, several instruments are used, among which the most widely used is the Fonseca anamnestic questionnaire and the Diagnostic Criteria for Temporomandibular Disorders (DC-TMD) assess- ment instruments. 8 Te purpose of our survey was to obtain the information on prevalence and severity of temporomandibular disorders among YARSI University employees in Jakarta, Indonesia, using the Fonseca’s questionnaire. Material and Methods Using cross sectional analytic design we conducted a survey about TMD in YARSI University. Sampling was completed using the purposive method and the study sample consisted of 225 employees, including both administrative and teaching staf. Te study sample had to meet the inclusion criteria, namely that respondents had never had prosthodontic treatment before. Exclusion criteria included respondents who use fxed orthodontics and those who had experienced TMJ trauma. Te prevalence and severity of temporomandibular disorders were assessed using the Fonseca anamnestic index. 8,9 Te Fonseca Index is ofen used to look at the severity of TMD in individuals based on the following classifcations: mild, moderate, severe and no TMD. Te Fonseca questionnaire consists of 10 questions Department of Preventive and Public Health Dentistry, Faculty of Dentistry, University of YARSI, Central Jakarta, Indonesia * Correspondence to: Helwiah Umniyati, Department of Preventive and Public Health Dentistry, Faculty of Dentistry, University of YARSI, Central Jakarta, Indonesia helwiah.umniyati@yarsi.ac.id Received: 1 July 2020 Revised: 2 July 2020 Accepted: 19 July 2020 Available Online: 1 August 2020
