Aim: There is an increased awareness for aesthetically pleasing restorations among patients in current practice. This study aims to determine which among the three named methods is better for shade selection in aesthetic dentistry.

Materials and Methods: Two VITAPAN classical shade guides were used for this study. 9 shades were selected from the 1st shade guide (A1, A2, A3.5, B1, B2, B3, C1, C2, C3) and were randomized. A total of 10 selected participants were asked to identify each randomised shade with the 2nd shade guide. The Canon 5D camera with ISO 200, shutter speed 1/100sec, F22 was used for capturing images of the 2nd shade guide. Photoshop CS3 Software was used for developing the digital shade guide. The participants were asked to match the randomised shades from the 1st shade guide with the prepared digital shade guide. The 3rd photographic shade guide was prepared using a polarised filter on the Canon 5D camera with the same settings. The participants were asked to match randomised shades with the prepared photographic shade guide.

Results: Total observations made during the study were 270. Cross table statistical analysis (Chi-square test) done using SPSS 20.0 showed statistically significant difference between conventional and digital photography (p=0.049). Analysis between digital photography and polarizing filter photography did not reveal a significant association(p=0.181).

Conclusion: Digital photographic method was most accurate among the three shade selection methods. It can be used to obtain aesthetic results.
