Classification of Supernumerary Teeth
Supernumerary teeth can be classified according to the location and the morphology. The supernumerary teeth present in the front teeth are called Mesiodens. The deciduous teeth are normally conical and straight but the permanent teeth can be differentiated into different shapes. They can be classified into four types according to the morphology. These are:
Conical Supernumerary Teeth
Tuberculate Supernumerary Teeth
Supplemental Supernumerary Teeth
Odontoma, This can be complex composite odontoma and compound composite Odontoma
Conical Supernumerary Teeth
They are normally peg shaped and are present between the front teeth and are known as the Mesiodens. They develop ahead or with the formation of root but some times they are impacted and lie inverted in the palate. Rarely do they cause hindrance in the eruption of the permanent teeth but they can cause the rotation or the displacement of the permanent teeth.
Tuberculate Supernumerary Teeth
As the name implies they have more than one cusp or tubercle and are mostly present palatally to the central upper incisors. Their root formation is delayed and they are usually paired. It is very rare that they erupt and they can cause the delayed eruption of the incisors.
Supplemental Supernumerary Teeth is the duplication of teeth in normal series. Mostly it is found in lateral incisor, molar and premolar region. Most of the deciduous teeth are supplemental and are never impacted.
