    Introduction: Maximal opening of the mouth is described as the greatest distance between incisal edge of maxillary central incisor to the incisal edge of mandibular central incisor when the mouth is opened as wide as possible painlessly or as the interincisal distance plus the overbite. Maximal mouth opening (MMO) is an earliest marker in detecting any TMD. However, MMO varies considerably with age, gender, facial type, and weight. The aim of this study is to determine the correlation of MMO with age, gender, height, weight, and facial type. Material and Methods: This is a cross-sectional study conducted among 150 pediatric patients who visited Saveetha Dental College and Hospitals for their routine dental checkup. They were randomly divided into three age groups: Group I - children of age 6–8 years, Group II - children of age 8.1–10 years, and Group III - children of age 10.1–12 years. For each child, three readings of MMO were noted and mean of those values was considered. Age, sex, facial type, height, and weight of the children were recorded simultaneously. Pearson correlation was used to determine the relationship between the different parameters. Results: The estimated average MMO measured for girls and boys in the age group of 6–8 years was 43.54 ± 1.26 mm and 43.87 ± 1.19 mm, respectively, in 23 children having euryprosopic facial type. Among 26 leptoprosopic facial type children, the average MMO was 43.44 ± 1.18 mm and 43.96 ± 0.73 mm for girls and boys, respectively. In case of 18 children having mesoprosopic facial type, the average MMO was found to be 43.52 ± 1.16 mm for girls and 43.88 ± 1.20 mm for boys. The estimated average MMO measured for girls and boys in the age group of 8.1–10 years was 45.97 ± 0.38 mm and 47.46 ± 0.37 mm, respectively, in 13 children having Euryprosopic facial type. Among 14 leptoprosopic facial type children, the average MMO was 46.5 ± 0.55 mm and 44.78 ± 0.39 mm for girls and boys, respectively. In case of 13 children having mesoprosopic facial type, the average MMO was found to be 45.85 ± 1.23 mm for girls and 45.25 ± 0.52 mm for boys. The estimated average MMO measured for girls and boys in the age group of 10.1–12 years was 46.38 ± 1.44 mm and 48.55 ± 0.16 mm, respectively, in 21 children having euryprosopic facial type. Among 14 leptoprosopic facial type children, the average MMO was 43.87 mm and 47.84 ± 1.15 mm for girls and boys, respectively. In case of 13 children having mesoprosopic facial type, the average MMO was found to be 47.61 ± 1.83 mm for girls and 47.51 ± 2.26 mm for boys. Conclusion: There was a significant difference in MMO between males and females, with males having higher values in all age groups. MMO is seen to increase with age in a statistically significant manner.
