The interrelationships of a modified Tooth Cervical Height Index (Davies et al. 1969) and tooth irregularity were evaluated on the posterior teeth of 90 skulls. Two readings were made for tooth displacement, rotation, and the Tooth Cervical Height Index for each maxillary and mandibular first bicuspid, second bicuspid, and first molar. The average Tooth Cervical Height Indices of the 6 posterior teeth ranged from 3·34 mm. for the mandibular first bicuspid to 1·63 mm. for the maxillary second bicuspid. Within each skull a definite relationship existed between the bone heights of the various teeth, viz., where a high recording was made on any one tooth there was tendency for high scoring on the remaining teeth of that skull. Tooth irregularity did not appear to have any association with the alveolar bone height.
