Correlation between Combined Width of Maxillary Anterior Teeth, Interpupillary Distance and Intercommissural Width in a Group of Indian People

Abstract

ABSTRACT Purpose The objective was to evaluate the correlation between the width of distal surface of canine (CWC), interpupillary distance (DMP) and intercommissural width (DCM) in a group of central Indian people. Materials and methods A total of 540 central Indian subjects (277 males and 263 females) aged 19 to 30 years were selected. DMP and DCM were measured on subject's face using digital vernier caliper [Mitutoyo (UK) Ltd.] with precision of 0.01 mm. Irreversible hydrocolloid impression of the upper arch was taken, and a cast was poured with dental stone. The CWC measurements were done on these casts with the help of a dental floss fixed between the distoproximal contacts of upper canines using a dental tape. Spearman's correlation test was used to determine the correlation between the three variables studied. Results The results revealed that the correlation between CWC-DMP was 0.015 and CWC-DCM was 0.031. The correlation showed negative values when compared between the sexes. Also, the proportions were calculated: DMP/CWC and DCM/CWC for the whole sample and for the sexes found no statistical significance (p > 0.05). Conclusion The results of this study suggest that the examined interpupillary distance and intercommissural width cannot be considered reliable guidelines in the selection of artificial upper frontal teeth. However, they may be used as a useful additional factor combined with other methods for objective teeth selection in complete denture therapy.
