Abstract
Introduction: The anterior teeth are primarily selected to satisfy esthetics. Their selection requiresthe dentist’s artistic skill and scientific knowledge. This clinical study was conducted to explore therelationship of interalar and intercommissural distance with the combined width of maxillary anteriorteeth.
Methods: Measurements of the parameters was made using a Digital caliper. The patient was seatedup right position and asked to look straight; the intercommisural and interalar width were measuredbetween commissures and ala without applying pressure. The combined width of maxillary anteriorsform the distal surface of left and right canines were measured with a dental floss, which was thensectioned and measured. Each parameter was measured three times and the average value was computedand recorded.
Results: Mean Interalar, intercommisural and intercanine distance were 34.72 mm, 48.9 mm and49.61 mm respectively. Statistical analysis revealed a highly significant difference between the interalarwidth, intercommisural width and intercanine width of male and female respectively. Spearman’srho analysis showed a highly significant correlation between Inter canine and both inter alar width(r=0.098, p <0.04) and Intercommisural width (r=0.234, p <0.05). Similarly, Spearman’s rho analysisin both sexes showed a highly significant correlation between intercanine and intercommisural widthhowever such correlation was not seen between intercanine and inter alar width.
Conclusions: This study concluded that there is significant correlation between interalar andintercommissural width with the combined width of maxillary anterior teeth. The inter alar and intercommissural width may be a useful guideline for the selection and replacement of maxillary anteriorartificial teeth.
