Background:
The increasingly frequent removal of asymptomatic or pathology free lower third molars raises several questions. In this paper, the relationships between inclusion of impacted third molars and facial typology, in studied in order to have a further evaluation parameter for their removal.
Methods:
The study was carried out an 50 cephalometric radiographs. The patients, 25 males and 25 females, have been submitted to surgical treatment at our oral Surgery Department to remove the lower impacted third molarst.
Results:
Among patients admitted for impacted third molars removal there was a larger percentage of brachyfacial (84% of the males, 71% of the females) in comparison with normofacial (8% of the males, 19% of the females) and dolichofacial (8% of the males, 10% of the females).
Conclusions:
The facial type, characterised by a shortened vertical dimension of the lower third of the face and an anticlockwise mandibular growth, presents a greater risk of included wisdom teeth.
