Only 25% of all mesiodentes spontaneously erupt into
the oral cavity. If unerupted, the tooth can alter both the
eruption of the permanent incisors and the resulting occlusion.
12 Furthermore, in 75% of cases, the incisor erupts
spontaneously once the mesiodens has been removed.21,28
Therefore, once a mesiodens has been diagnosed, the
clinician must decide on treatment to minimize further
sequelae. Management is discussed here according to the
developmental stage of the dentition: primary, mixed or
permanent.
