A Case of Congenital Supernumerary Teeth in an Ovine Dental Pad
In this case report, the supernumerary teeth described are normal in shape but reduced in size, and were therefor classified as what?
focal microdontia
A Case of Congenital Supernumerary Teeth in an Ovine Dental Pad
In this case report, the supernumerary teeth were considered to be normotopic or heterotopic? What position in the dental quadrant did they correspond with?
Normotopic (due to the presence of dental alveoli observed on radiographs).
L+RmaxI4 (fourth incisior teeth)
A Case of Congenital Supernumerary Teeth in an Ovine Dental Pad
The etiology of supernumerary teeth is uncertain, but various causes have been proposed, including: (name 5)
1) Atavism (reappearance of traits that were lost in generations prior)
2) dichotomy of the tooth germ
3) excessive growth of the dental lamina
4) hereditary factors
5) other diseases
