Materials and Method: The sample consisted of 146 lateral profile photographs of young adults with good facial harmony (control group) and 135 lateral profile photographs of young adult patients seeking orthodontic treatment (study group). The photographs were taken under standard conditions with the subjects in posed smile and the maxillary incisors clearly visible. The images were resized and the measurements were made using Image Tool version 3. The A-P position of the maxillary central incisors relative to the forehead was measured and the data subjected to statistical analysis. Results : 90.4% of young adults in the control group had maxillary central incisors positioned ahead of FFA point of forehead and only 9.6% had maxillary central incisors positioned behind the FFA point whereas in the study group, 71.3% of young adults had maxillary central incisors positioned ahead of FFA point and 28.7% had maxillary central incisors positioned behind FFA point of forehead. Conclusion: The FFA point of the forehead is a useful landmark in assessing the position of the maxillary central incisors in young adult patients seeking improved facial harmony.
