To evaluate the existence of different esthetic smile criteria in a section of North Indian population.

Materials and methods

A total of 100 students from Manav Rachna International University were selected based on the inclusion criteria. Two photographs were taken (smiling face and smile) using Digital Single Lens Reflex camera. The statistical analyses used were descriptive statistical tests and Spearman correlation after the images were analyzed using Digimizer image analysis software for different esthetic smile criteria.


The coincidence of the facial midline with the arch midline occurred in more than half of the students. Most of the subjects presented parallelism between the incisal plane and the interpupillary line. Mostly parallel or straight smiles were also most commonly observed and the gingival display and the amount of gingival display were relatively less observed.


There exists a relationship between facial midline, interpupillary line, smile arc, gingival display, and facial esthetics.

Clinical significance

This article describes the existence of different esthetic smile criteria in enhancing the facial esthetics for a pleasing smile.
