ABSTRACT
Bizygomatic distance is a relevant reference used to assist and to guide the choice of antero superior prosthetic teeth, especially when no information about the natural teeth was available. The aim of the present paper was to determine the distance between the canine tips from a bizygomatic distance and to estimate the width of the upper central incisor in normal-dental-facial indices of Cameroonians. Materials and methods: A cross-sectional study of 900 normal Cameroonians of both sexes was conducted. Measurements of bizygomatic distance, distance between the two upper pointers and the mesio-distal width of the upper central incisor were made with a manual and a digital caliper respectively. The equation for calculating the distance of higher canine pointers from the bizygomatic distance was DCT = 0.081 (BZD) + 26.201. The width prediction of the central incisor was obtained by the following formula: WUCI = 6.252 + 0.019 (BZD) + 0.035(DCT) + 0.062 (Reg cul) + (?0.479) sex. Reg.cul represents the cultural region of origin. Results: Female sex was represented by 56.6% against 43.30% males. The average age was 37± (32 SD) years. The average value of the bizygomatic distance was 130.23 mm, the width of the upper central incisor was 9.39 mm while the distance between the two upper canine pointers was 36.70 mm. Significant correlations between bizygomatic distance, the distance between the two canine pointers, and the width of the upper central incisor were found (P = 0.000). Conclusion: The width of the central incisor and the distance between the two upper canine pointers may be determined by the non-invasively method of the bizygomatic distance in the perspective of choosing the teeth for dental prosthesis.
