Forensic odontology, of late is gaining increasing importance in criminal investigation. There has been a lot of interest of the use of facial reconstruction as a means of identification when other evidence is insufficient. Several 2D and 3D manual or computer-aided facial reconstruction techniques have been developed. Facial reconstruction however, is a time consuming, tedious procedure, and is often impractical due to the lack of proper data base and cost factor.
Aim: To develop a simplified manual technique using the soft tissue thickness as determined by Lateral cephalograms to reconstruct a likeliness having close resemblance to the actual face.
Material & method: 30 lateral cephalograms (15 males, 15 females) of local population will be traced and soft tissue depth at predetermined anatomical points will be recorded. Using this facial reconstruction will be attempted manually using clay to give an outline to the skull.
Results: The comparison of individual soft tissue points with the mean values of all soft tissue points using paired t test did not show any significant variation. (p>0.05). a variation however, was seen between soft tissue thicknesses at individual points between males and females.
Discussion: The soft tissue depths determined in this manner could be used to reconstruct the profile of subjects where only the skull is available. However, we emphasize that this is only a pilot study and needs to be validated further with a larger sample size.
