RESULTS: 176 (76.2%) investigated were with all third molar germs, but 55 (23.8%) were with missing of this tooth. Missing of all 4 third molar germs were found in 13 (23.6%), missing of 3 third molar germs were found in 4 (7.3%), missing of 2 third molar germs were found in 19 (34.5%) and one missed third molar germ was found in 19 (34.5%) too. In the sample of 112 boys were found 27 (24.1%) with missing third molar germs, but most of them were with one missing: 10 (37%) investigated.
