Correlative Evaluation of Temperaments and Various Proportions of a Smile for Invocation of a Customized Smile in Young Individuals Using Digital Photography

Background: This study aimed to assess and correlate young people’s temperaments with various elements of their smiles using digital photography, with the objective of aiding clinicians in customizing smiles that express patients’ personalities and lifestyles. The objective is to attain harmony between dental restorations and the patient’s overall physical appearance, aligning with their values and attitudes as influenced by their temperament. Materials and Methods: The study included the participation of 160 individuals ranging in age from 18 to 38 years, all selected from the dental college. Prior to participation, informed consent was obtained from all individuals. Participants provided informed consent and completed a self-reporting questionnaire to assess temperament. Dental proportions, including golden proportions, recurrent esthetic dental (RED), and golden percentage, were evaluated through digital photography using a Planmeca software. Measurements of incisor and cuspid widths were analyzed, and proportions were correlated with temperament categories. Duration of study is 3 year statistical analysis using Chi square tests in SPSS version 27.0 indicated significant relationships between dental proportions and temperament. To make sure that the classification is precise and in line with the study's temperament framework—which was determined through questionnaire analysis—participants must adhere to a set of requirements. Results: Maximum number of patients exhibited golden percentage which was followed by RED proportion, golden proportion, not in proportion, RED, golden proportion RED, and golden percentage. On evaluation, it was found that 29 participants reflected a golden proportion in choleric temperament, 28 reflected a RED proportion in melancholic, 13 RED in phlegmatic, and 25 reflected a golden percentage in sanguine temperament. Nevertheless, the overall percentage of patients was higher in the golden percentage compared to other proportions. Gender may impact the result of the study. Conclusions: A balanced smile is crucial for dentofacial esthetics, and this study advocates customized smile design by combining facial and personality analysis. The study suggests using golden proportions in strong temperaments, golden percentage in dynamic temperaments, and RED proportion in sensitive and peaceful patients. The concept of visagism, combining tooth form, face form, and personality, is proposed for further exploration and application in smile designing.
