Cephalometric study of elderly with nearly intact dental arches.
OBJECTIVE
The purpose of this study was to investigate the craniofacial morphology of elderly people with many remaining teeth using cephalometric analysis.


METHODS
The subjects were 30 Japanese elderly who participated in the '8020 campaign 2001' in Bunkyo Ward, Tokyo, organised by The Dental Association of Tokyo, as well as 30 Japanese young adults with normal occlusion. Lateral cephalograms of all subjects were analysed using the Coben method.


RESULTS
In the female elderly group, the lower face depth was smaller than in the younger adults. In the male elderly group, the height and depth of both the total face and the lower face were longer than in the younger group. In comparing the 8020 achievers with the younger group, the proportion of the lower facial height was greater than the upper facial height, and this finding was more pronounced in women than in men.


CONCLUSIONS
For the lateral facial pattern of the elderly, a reduction of lower facial height because of tooth occlusal reduction was not apparent. It was clear that there are age differences for males and females; in addition, differences in the total face and lower face area of the elderly group were due to their having many remaining teeth over a long time period. Also, these changes were more apparent in women than in men, and it is clear that there is a male-female difference in ageing.
