ABSTRACT
The biocompatibility of unprecious metal alloys, particularly those containing nickel, is controversial. Nickel is a known cancerous agent, and the main responsible of metal allergic reactions in human. Dentists must be aware about risks related to this material. It is mandatory carry out careful anamnesis about nickel hypersensitivity avoiding it in subject with known hypersensibility.

The Author's aims was to review the role of the lower third molars in delayed crowding of the jaw. A global agreement exists on the fact that lower molars should be considered only one between several factors able to cause malocclusion. Finally, the germectomy of the third molars has to be performed only in carefully selected patients after a comprehensive diagnostic evaluation of the single case.

The high incidence of third molar extraction is related to their frequent pathology. The use of an uncomplicated and reliable diagnostic and therapeutic protocol therefore became extremely important. The protocol has to include careful selection and preparation as well as the appropriate choice of instruments and surgical techniques. This is even more important, considering the elective nature of the procedure and the local and more rarely, systemic complications that could develop.
