The incidence and distribution of alveolar fenestrations and dehiscences and their association with root prominence and occlusal faceting were investigated in 87 dry Bedouin jaws derived from the region of the southern Negev. Fenestrations were most frequently found in maxillary molars and canines and mandibular canines and lateral incisors. Dehiscences were most consistently observed in mandibular canines and first premolars. Maxillary fenestrations were consistently found in the apical half of the root length as were 60% of mandibular fenestrations.
