Smile photograph analysis is one of the identification methods used in forensic anthropology and odontology, and it can be a useful tool in identifying individuals. The analysis of a smile photograph involves examining the unique characteristics of an individual’s smile, such as the shape of their teeth, the spacing between teeth, and the size and shape of their lips. In forensic anthropology, smile photograph analysis can be used to help identify individuals who are missing or are deceased. This method can be particularly useful in cases where there is no other means of identification, such as when the body is badly decomposed or damaged. By comparing a smile photograph of a missing or deceased person to photographs of known individuals, forensic anthropologists can often make a positive identification. This research evaluates the comparison and identification efficiency of this method when applied to photographs of an individual in different stages of life.
