Abstract
The aim of the study is to examine whether presence of third molars contribute to changes in anterior dental alignment in the lower jaw in individuals from adolescence to young adulthood, when compared to the development in individuals with congenitally missing third molars.
Our study suggests that mandibular third molar is not a contributing factor to crowding in mandibular alignment.
A greater reduction in intercanine width occured when mandibular third molars were missing when compared to cases where third molars were present.
