The mouth opening can be used to assess the function of the temporomandibular joint. The average mouth opening differs in various populations, and the aim of this study is to investigate the mean of the normal mouth opening in the Indonesian population and to analyze the difference between gender and height groups. A cross-sectional study was conducted on 182 subjects, ages 17-22, from Universitas Indonesia. A student's t-test showed significant differences between males and females (p < 0.05), with males (44.8 ± 4.9mm) having significantly larger mouth openings than females (37.6 ± 4.9 mm). A one-way analysis of variance (ANOVA) test also showed a significant difference between the taller and shorter height groups (p < 0.05). Thus, the mean mouth opening differs significantly between gender and height groups.
