Relationship of intercommissure width with buccal corridor display during social smile
Introduction: Smile frame work is determined by the position, shape, shade of the teeth; texture, colour and lines of the gingiva and the lips. Many features are said to increase the pleasing effect of a smile or they render beauty to a smile e.g. consonance in a smile, appropriate gingival display, harmonious gingival scaffolding, colorful gingiva, minimal buccal corridors, appropriate incisal show during smiling and so on. Having minimal buccal corridors is a preferred esthetic feature for both men and women. The purpose of this study was to establish the correlation between inter-commissure width and the buccal corridor area show of a patient during posed smile.
Material and Methods: A sample of 147 patients was selected through non-probability consecutive sampling. Pictures were taken in the same environment for every patient. Inter-pupillary distance and the inter-commissure width at rest were measured on the frontal photographs and were compared.
Results: The correlation analysis with Pearson correlation showed that the correlation of buccal corridor area show (in mm on frontal smile) with inter-commissure width was not statistically significant.
Conclusions: There was an insignificant association between inter-commissure width and buccal corridor space during smiling.
