Accidents that occur during the eruption of wisdom teeth are considered almost compulsory. They take place because of phileogenetic, ontogenetic and anatomical conditions. Phileogenetic conditions are represented by the constant growth of the human cerebral activity, which increases the cranial capacity to the prejudice of the maxillaries. Besides, modern means of cooking diminish the chewing role of the tooth. This is how the philogenetic tendency of disappearance of the third molar is explained. According to Burlibasa, eruption accidents of the inferior wisdom tooth occur in the presence of two factors: favouring and determining. Favouring factors are: the position of the wisdom tooth in the bone structure, a close raportation to the no. 2 molar and the structure and positioning of the hood onto the occlusive
surface of the no. 3 molar. The wisdom teeth included can remain still for long periods of time, without causing any disturbances and can be accidentally discovered by a simple radiological examination, done for a different reason. The absence of inferior molar teeth doesn’t necessarily mean their inclusion, as they can be absent at 40% of the population.
