Aims and Objectives: The present study was done with an aim of taking facial photographs in a standardized manner to eliminate the intra observer errors and also to observe the reliability and repeatability of the same in successive visits.
Methods: A single individual of 23 years old was selected; photographed in NHP with mirror method and in FH-plane by orienting the head with the help of a specially designed device and a laser source (Bosch GLL 2X professional) by using a Cannon EOS 1300D DSLR camera for 25 times. Standard analyze the results using SPSS software version 22.0
Results: Standard deviation values are lower for laser group compared to NHP group in both profile and frontal photographs suggesting the laser technique for head positioning in FH-plane is better in reliability and repeatability than the NHP. Chi-square test suggesting that frontal photographs for both NHP, FH-plane is statistically significant while the profile groups are not statistically significant.
Conclusion: This method allowed us to take facial photographs of patients with head positioned such that the FH plane is parallel to the floor, which helps in standardization of photographs and superimposition with lateral cephalograms.
