ABSTRACT
Objectives: to determine the relationship between TMD and the range of mouth openings in children in Cimahi City. Methods: 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. Results: 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. 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.
