Aim: Esthetic dentistry involves shade determination. The conventional shade guide is a subjective method whereas spectrophotometer is an accurate but an expensive method. The need for determining the shade using an effective and inexpensive method is a clinical requirement. The study is aimed at comparing mobile dental photographs to spectrophotometer as an effective means of shade determination. Material and Method: 50 participants with no restorative or traumatic changes on the left central incisor were selected. Shade was determined using spectrophotometer and mobile photographs. The L*a*b* values obtained from each were noted. ΔE was determined and the agreement between the readings obtained by the two different methods was compared and subjected to appropriate statistical analysis. Results: The results showed that there was a statistically non-significant difference seen for the values between the 2 techniques (p>0.05). The mean ΔE was 1.5. There was a statistically significant difference between the proportion of ΔE more than and <2, between spectrophotometric and mobile dental photography methods (P < 0.01) with higher proportion of <2 ΔE. Conclusion: The mobile dental photograph is an effective reliable means of shade determination. It also can be used as an adjunct for shade communication and establishing the characterization for an esthetic restorations. Clinical significance: Mobile dental photographs has been established as one of the effective means of shade determination and communication without an additional expenditure. It can help mimic not only the shade but also the characterization by the lab personnel as the photograph communicates these details for reference.
