Abstract

Background: The choice of the size of artificial teeth takes an important place in the removable
prosthodontic treatment. However, the standards or proportions commonly used as a guide have
been developed mainly on Caucasian populations.
Objectives: to investigate the relationship between intercanthal distance and the anterior maxillary
teeth size in Sudanese population.
Methods: This is a descriptive cross sectional study conducted in 114 subjects, (45 males - 69
females), from Khartoum and Juba Universities. The age range was from 18-46 years. The
intercanthal distance (I.C.D) was the measurement taken between the median angles of the
palpabral fissure. Maxillary intercanine distance was obtained by measuring a line from the tip of
the canine on one side, to the canine on the other side. An electronic digital caliper (Narex –
Czechoslovakia) was used for all measurements. Data were analyzed using Person chi–square test.
Results: a significant correlation is found between intercanthal distance and maxillary intercanine
distance in all subjects (P-value 0.015), and in females who had a (P-value of 0.006). Maxillary
intercanine distance may be estimated by dividing I.C.D by factor 0.9.
Conclusion: These results could be used as a helpful guide for selection of anterior teeth width in
the Sudanese population.
