Alveolar defects in human skulls.

Abstract The prevalence and intra-oral distribution of dehiscences and fenestrations was determined in 398 19th Century British skulls. The percentage of teeth and skulls with dehiscences and fenestrations decreased with age and over half of the affected skulls, with the exception of the oldest age group, had two or more defects. Dehiscences were consistently observed on the mandibular canines and first premolars and the maxillary canines and first molars. Fenestrations were found most frequently on the maxillary first molars and the mandibular lateral incisors and canines.
