A beautiful smile is the most striking feature in the face. However beauty is not absolute and is extremely subjective. The aim of this study is to determine the prevalence of 'Golden proportion and Recurring aesthetic dental proportion' in individuals presenting attractive smiles. 214 smile photographs of students of SDM Dental College aged 18-25 years with natural dentition were analysed for their attractiveness based on 6 predetermined criteria.

RED proportion was present in 6.6% of population as opposed to golden proportion which was found in 0.6% of population. It was found that 70% RED was more prevalent than Golden Proportion in attractive as well as unattractive smiles.
