Abstract The current knowledge base for evaluating the

influence of ethnic origin on wisdom tooth eruption is still

inadequate. We therefore analyzed and compared the chronology

of wisdom tooth eruption in three ethnic populations—German,

Japanese, and black South African—based

on evidence from 2,482 conventional orthopantomograms.

The investigated German population ranked in the middle

in terms of the age of wisdom tooth eruption. The black

South African population was the fastest and the Japanese

population the slowest in terms of reaching the respective

eruption stages. Population-specific reference data should

be used when evaluating wisdom tooth eruption for the

purpose of forensic age estimation.
