Abstract:
This investigation was conducted on 110 individuals, (40 males and 70 females) in the age range of 12-18 years. The results revealed the mesiodistal crown dimensions of teeth of males to be more than that of the females. Further the ratio of the mesiodistal crown dimension of the maxillary lateral incisors to the maxillary central incisors was 80% in females and 78% in males. The total arch length in males was 117.77 mm in maxilla and 111.60 mm in mandible, while in females, the figures were 113.98 mm in maxilla and 107.10 mm in the mandible.
