This research aimed to determine the relationship between playing the violin and the severity of TMD and the maximum pressure on the chin rest within safe limits while playing the violin, to prevent TMD occurrence. The 20 violin players of OSUI Mahawaditra and MYSO orchestra were undergoing the examination and interview. Measurement of the pressure on the chin rest was done using a Flexi force device attached to the chin, which will measure the chin pressure on the instrument (N). The highest maximum pressure is 15.157 N, while the lowest maximum pressure is 0.126 N. The most elevated average pressure is 6.203 N, and the most moderate average pressure is 0.025 N. There is a strong relationship between chin pressure on the chin rest and TMD conditions in the violinist. There is no relationship between the frequency and duration of violin training with TMD conditions in violin players. [ABSTRACT FROM AUTHOR]

This study aimed to provide information about the prevalence of temporomandibular disorders (TMD) in young violin orchestra players as an illustration of TMD events in violinists in Indonesia. The subjects were 68 violin players of OSUI Mahawaditra and MYSO orchestra. The data gathered through an interview and some questionnaires. The TMD clinical examination included the palpation of head and neck muscles and the measurement of mouth opening. The caliper used for mouth opening height, while two fingers used for muscle palpation. Based on Fonseca's analysis, the prevalence of TMD revealed in young violinists is 90%, while the prevalence of TMD based on DC-TMD form is 80%. This study concluded that there is a high prevalence of TMD in young violinists from several orchestras in Indonesia, with the values that more than 50%. [ABSTRACT FROM AUTHOR]
