Some informations on dental tissues obtained from observations on a complex odontoma

Morphological features of enamel and dentine have been studied in a complex odontoma. The enamel had a prismatic structure with an abundant organic matrix in the inner part and a laminar stratified pattern at the surface. A cell layer above the enamel had the characteristics of maturation ameloblasts. Dentine had morphological characteristics of a normally developed tissue. One of the aggregates forming the odontoma had a structure similar to a normal tooth but the pulp-dentine complex was lacking in the odontoblast cell layer. The loose pulpal tissue of this structure was also devoid of blood vessels and nervous structures.
