- Cephalic Index is defined as the ratio of the maximum breath of the skull to the maximum length of the skull multiplied by 100.
- It was given by Swedish Anatomist Anders Recitus and is used to determine the race of a person.
- It has no unit as it is a ratio.
- Anterior Posterior is maximum in Dolicocephaly
- The Skull Bone is the best bone for the determination of race of a person in 90-95% of cases
- The best single criterion for the determination of Mongoloid Skull bone is the presence of “Shovel Shaped” upper incisors
