Results: Our present study shows that socio-economic status has no effect on the development and eruption of third molar teeth at various stages.

Conclusion:There is no co-relation of socio-economic status, and physical characters have no effect on the eruption and development of various stages of third molar teeth. Third molar teeth eruption alone should not be used for age estimation.  Third molar agenesis is more in case of girls than in boys.
