•Purpose: determine the incidence & distribution of fenestration \ dehiscence in human skulls.
•N= 3,416 teeth present and examined in 108 adult skulls of human Mexican Indian origin.
1.The skulls varied in age from the early 20s to past 70s.
2.The number of fenestrations & dehiscences, occlusal wear pattern and prominence of each tooth root were recorded.
Most highlighted Results:
1. 7.5% of all teeth examined exhibited fenestrations (4.3%) or dehiscences (3.2%).
oMax & Mand anterior teeth > posterior teeth.
o12.5% of all Max & 14.3% of Mand anterior teeth had either fenestrations or dehiscences.
oMost often in Max 1st molars and cuspids & Mand cuspids.
ocommonly associated with prominent tooth roots.
2.No relationship could be found between number of bony defects present & age of skull.
3.No definite relationship could be shown between fenestrations & teeth with trauma.
Fenestrations and dehiscences could be found in any age group affecting mainly anterior teeth and teeth with prominent roots.
