Correlation of age and incremental lines in the cementum of human teeth.
It has been long recognized that cementum thickness increases with age. Much literature has recently been devoted to utilizing incremental lines in cementum as an aging criterion in animals, but only one study has been done suggesting this technique in humans. Thirty-one teeth of known age were histologically stained and sectioned to observe incremental lines. Direct predictions of age based on these lines underestimated the age of older specimens. However, there was a correlation between number of lines and age, and with a large enough specimen size, a computer-generated formula for age prediction may be possible.
