Abstract

Temporomandibular Disorder (TMD) often occurs especially in the age range of 20 to 40 years and can occur in children of productive age, so it can disrupt productivity and reduce the child^s quality of life. One of the symptoms of Temporomandibular Disorders is the limited range of the mouth opening. This study aimed to determine the relationship between TMD and the range of mouth openings in children in Cimahi City. A cross-sectional approach was used in this research. 47 students at SD Cimahi Mandiri 2, aged 8 to 12 years, were invited to participate in this study. Sample selection was carried out using stratified random sampling, forming subpopulations with relatively homogeneous variables. Subjects filled out a modified Fonseca questionnaire in Indonesian, and the size of the mouth opening was measured. From the Fonseca questionnaire, the calculated validity test results were > r table 0.361, and the reliability test results were 0.721 with Cronbach^s Alpha, indicating that the Fonseca Questionnaire was valid and reliable. Data were normally distributed. The results of the correlation test using Pearson obtained a probability value of 0.023 (p<0.05) and a correlation r of -0.267. The conclusion is that there was a significant relationship between TMD and mouth opening size in children aged 8 to 12 years in Cimahi City with a low level of correlation. The higher the TMD score, the lower the size of mouth opening.
