Maximum mouth opening (MMO) is a significant and very important diagnostic criterion for many clinical conditions. However, the number of relevant studies is limited, and the relationship between age and MMO has not yet been established. The purpose of this study was to measure and analyze the MMO of ethnic Kashmiri adults and to examine the possible relationship between age and MMO.
Materials and methods: A total of100 adult subjects aged 20−80 years (50 males, 50 females) were randomly selected. Subjects were divided into two age groups:
Group I: 20−39 years (young),
Group II: 40−59 years (middle).
Independent sample t test and one-way analysis of variance (ANOVA) were used to examine differences in MMO relative to sex and age groups. The average MMO of the male subjects was found to be more than females in both age groups. The mean maximum mouth opening in males and females in group I was 54.37mm and 47.6.9mm and in group II was 50.17mm and 45.25mm respectively as shown in table 1. MMO significantly decreased with increasing age, regardless of sex.
Conclusion: Within the limits of this study, we concluded that both sex and age have significant influences on the MMO value of Kashmiri population, and age is a significant predictor of MMO measurements.
