ABSTRACT

Background: Maxillofacial region’s reference points like interpupillary distance, intercanthal distance, interalar distance and bizygomatic width can significantly contribute toward reconstruction of two-dimensional (2D) facial profiles.

Aim: To find correlation between intercanthal to intercanine and interalar to intercanine distance for maxillary anterior teeth selection.

Methodology: This study was conducted at de’ Montmorency College of Dentistry/ Punjab Dental Hospital, Lahore from 29-08-2013 to 28-04-2014. Sampling technique was non-probability purposive. 200 subjects are estimated for correlation of intercanthal distance to intercanine distance and correlation of interalar distance to intercanine distance as r=0.302.

Results: Out of 200 cases, 102(51%) were 20-40 years of age while 98(49%) were ranging between 41-60 years of age, mean±SD was calculated as 41.01±11.90 years, 135(67.5%) were male and 65(32.5%) were females, correlation among maxillary intercanine distance with other facial land marks shows the distance of intercanine was 37.26±3.91, it was 41.26±4.57 for interalar and 34.50+2.51 was recorded for intercanthal, the value of R2, the coefficient of determination, is 0.0893 for intercanine to intercanthal and 0.0018 for intercanine to interalar.

Conclusion: We concluded that intercanthal distance to intercanine distance is more correlated as compared to interalar distance to intercanine distance in Pakistani population.

Keywords: Maxillary anterior teeth, intercanthal distance, intercanine distance, interalar distance, correlation
