Correlation between bone level and age in contemporary dry Japanese skulls.

The correlation between the presence of dehiscence or fenestration and the severity of tooth attrition in contemporary dry Japanese adult skulls. Part I.

“…Tooth attrition has been used for estimating age in the field of legal medicine because of the known correlation of the severity of tooth attrition with age [18]. From an epidemiologic viewpoint, the severity of alveolar bone loss increases with age [27,28], although it is not correlated individually [16].…”

“…1) have been discussed in a number of previous studies [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. Such defects of the thin alveolar bone have been suggested to be due to anatomical factors [6][7][8]11,12,15,16] (buccolingual tooth malposition), occlusal function [4,5] or a number of other unidentified abnormal causes, but none of these have been clearly identified.…”
