The determination of sex plays a significant role in forensic medicine, especially in mass disasters. The skeleton bones are used most commonly as they are resistant to putrefaction and other factors. The most commonly used skeleton bones are Pelvis and skull bones. As the pelvis is more fragile compared to the skull, the fact that skull bone exhibits the highest sexual dimorphism, the usage of skull bone in sex determination has increased. A lateral cephalogram is ideal for the skull examination as it gives details of various anatomical points in a single radiograph, easily accessible and reproducible.
