Endodontic management of a fused mandibular third molar and distomolar
: A case report.
ST can be classified on the basis of the morphology (conical, tuberculate, supplemental, and odontomes), location (mesiodens, paramolar, distomolar
, and parapremolar), position (buccal, palatal, and transverse), and orientation (vertical or normal, inverted, transverse, or horizontal).
A study conducted in Turkish population has revealed that the most common supernumerary tooth was mesiodens, followed by premolar, lateral, distomolar
, paramolar and canine (9).
Ademas, se determino la angulacion del canino a la linea media, el nivel de erupcion con respecto a la raiz del incisivo cercano clasificandolo en estadio 1, 2, 3, 4 y 5 y la altura vertical con respecto a los incisivos centralesl Los dientes supernumerarios se clasificaron segun su ubicacion en mesiodens, paramolar, distomolar
y parapremolar, y segun el numero de dientes presentes, en unicos, multiples, unilaterales y bilaterales (13,14).
When classified by po- sition a supernumerary tooth may be referred to as a mesiodens a paramolar or a distomolar
Table 1 Classification Based On Form Classification Based On Position Conical Mesiodens Tuberculate Paramolar Supplemental Distomolar
Mesiodens were present in two patients (0.87%) Para molars in six patients (2.6%) and distomolar
was present in only one patient (0.43%).
The supernumerary teeth that occur between or just posterior to the central incisors are referred to as mesiodens; those in molar area are called paramolar teeth; and more specifically, those that erupt distally to the third molar are distomolar
In order of decreasing frequency, some authors consider that mesiodens are followed by distomolars
[25, 26], but others [21, 23] found that mesiodens are followed by lateral incisors and premolars.
Supernumerary teeth are common in the maxillary anterior area (mesiodens) and the maxillary molar area (distomolars
or fourth molars).
