Background: Recently in cosmetic dentistry the coverage of smile makeover has increased public awareness for dental aesthetics. This awareness of aesthetic smile is increasing day-by-day and playing a key role in various aspects starting from the sense of self welfare & confidence, social acceptability, outstanding performance at work and in relationships. Smile design is defined as “a systematic process governed by the psychology, health, function and rules of natural aesthetics to bring about some changes in soft and hard oral tissue within anatomical, physiological and psychological limitation, thereby creating a positive influence on the overall aesthetics of a person’s face and personality as a whole. Materials & Methods: Following smile parameters were quantified using AutoCAD Photoshop ruler software: Maxillary incisor exposure (MIE) (mm), smile index (SI) (mm), smile arc, buccal corridor ratio (%), most posterior maxillary tooth visible, anterior height of the smile (%) and posterior height of the smile (%). Statistical Analysis: The data were compiled and statistical analysis was done using the statistical package of social science (SPSS) software (version 12). To determine Maxillary Incisal exposure (MIE) and Smile index (SI) unpaired t-test was applied. Chi-square test was applied for assessment of most posterior maxillary tooth visible, smile arc, buccal corridor, the anterior height of smile & posterior height of smile. Results: Mean value was found to be 7.9 mm in boys and 8.16 mm for girls. The low smile line was found to be predominant in boys, while a high smile was predominant in girls. More girls (72%) than boys (62%) have a consonant smile. Girls displayed the second premolar commonly in contrast to boys , who displayed the first premolar. Parallel smile arc was noted more frequently in girls, while boys displayed flat smile arc commonly. Conclusion: Prosthodontist’s have the responsibility to design and create smiles following an organized and systematic approach. Smile analysis is an integral part of prosthodontic multifactorial treatment planning giving the best treatment outcome.
Keywords: Smile parameters, smile index, smile height, smile curve and buccal corridor.
