Intercanthal distance of a Sudanese population sample as a reference for selection of maxillary anterior teeth size

الملخص EN

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.
