BACKGROUND AND AIM: @entity2133 ( @entity2133 ) is used as a marker of masticatory pathology. However, @entity2133 among @entity1 varies considerably with their age, height, sex, and race. While accurate percentile of normal mouth opening and relationship with anthropometric measurement are not precisely defined for the Indian population, we designed prospective, observational study to define the percentiles for normal @entity2133 in our @entity1 . METHODS: A total of 985 @entity1 , 560 males and 425 females, in the age range of 5-18 years attending the pediatric clinic in a tertiary care center in Western India were studied. In addition to the basic demographic data, @entity2133 was measured in these @entity1 . The @entity1 were asked to open their mouth maximally until no further opening was possible. The distance from the incisal edge of the upper incisor teeth to the incisal edge of the lower incisor teeth was measured using a calibrated fiber ruler. Statistical analysis was performed to assess the impact of other anthropometric measures such as age, gender, and height on @entity2133 . OBSERVATIONS: The mean @entity2133 for males was 44.24 (  5.84) mm and for females was 43.5 (  5.19) mm. Age- and height-related percentiles were created for @entity1 and @entity1 separately, showing the 5(th), 10(th), 25(th), 50(th), 75(th), 90(th), and 95(th) percentiles from 5 through 18 years of age with 86-185 cm height. CONCLUSION: The @entity2133 percentile range for different age and height groups is established for the normal @entity1 . The mouth opening seems to increase with the age and especially with the height as per the skeletal growth. Height affects mouth opening more than the age.
