Abstract

Aims and Objectives: To assess the posed and dynamic smile and to compare the various attributes of smile in frontal, oblique and sagittal dimensions, in two different age groups (10- 15years and 18-25 years).

Materials and Methods: The posed and dynamic smile parameters were measured using digital video clips in 80 subjects of two different age groups (10-15years and 18-25 years). Total of 15 parameters were studied in 3 planes of space. The data was analysed using student`s t-test to compare smile parameters across the age groups, paired t-test was used to analyse the parameters of posed and unposed smile within the same age group and chi-square test was performed for the discrete data.

Results: The present study revealed significant differences in dynamic smile parameters between the two age groups. The parameters like Philtrum height and Smile index are more in older age group whereas the buccal corridor was more in younger age group. Significant differences were also recorded in various parameters in both the groups when the posted smile is compared with that of the dynamic smile.

Conclusion: In both the age groups, the dynamic and posed smile attributes are significantly different, except for buccal corridor and interlabial gap.
