Most frequently impacted teeth were third molars especially lower right ones. Most frequent ectopic teeth were canines especially upper left canines. Comparing the two jaws, impaction was more common in the mandible 52 [10.4%] than in maxilla 30 [6%], while 42 [8.4%] patients had impacted teeth in both jaws simultaneously. Only one patient had 5 teeth impacted. Most commonly ectopic teeth were maxillary canines which were 102 [60.5%].
