Clinical crown heights of permanent teeth in Nigerians.

The clinical crown heights of 2,048 permanent teeth were measured using a pair of dividers and a metre rule on stone casts of study models of subjects aged 21-45 years in order to establish the data for the clinical crown heights of Nigerians. A gradual increase in clinical crown height with advancing age was observed. The clinical crown heights of Nigerians appear to be shorter than the clinical crown heights of Caucasians.
