Aim: To evaluate Preston's ratio and Recurrent Esthetic Dental (RED) proportion in smiles of female patients who are satisfied with their smiles. Methodology: 86 subjects who fulfilled inclusion criteria for the study were selected. A distance of 30 inches was maintained between camera and subject. With the help of cheek retractor, cheeks were retracted and pictures of subjects were taken with camera. Images were transferred to computer. Using Bit rule software, mesio-distal width of upper anteriors was measured. Data were recorded and transferred to excel sheet. Data were analyzed using descriptive statistical tests and conclusion was drawn. Arthematic mean and student t test were employed to evaluate the data. Level of significance was, p=0.05. Results: Out of 86 smiles, 20 smiles presented with RED ratio. 27 smiles demonstrated Preston's ratio in lateral incisor to central incisor proportions, whereas 20 smiles demonstrated Preston's ratio in canine to lateral incisor proportions. Conclusion: Preston's ratio was more prevalent among lateral incisors and central incisors of all the smiles included in this study. But on analysis of canine to lateral incisor proportions, theory of Recurrent Esthetic Dental ratio and Preston's ratio displayed same results.
