Jameel / Ranganath, V.The aim of this study was to define shapes of maxillary central incisors and determine their relationship with the visual display of interdental papillae during smiling. A sample of 100 patients aged 20 to 25 years were recruited. Photographs were taken and gingival angle, crown width (CW), crown length (CL), contact surface (CS), CW/CL ratio, CS/CL ratio, gingival smile line (GSL), and interdental smile line (ISL) were measured. The data showed an increase in GA leading to an increase in CW and CS/CL ratio. Women showed a higher percentage of papillary display compared with men. This study reinforces the proposed hypothesis that the shape of the teeth and papilla affect the periodontium.
