Denticle
The term denticles called two of morphology and genesis ago completely different hard tissue formation present in or on the edge of the tooth pulp occur with greater expansion in the X-ray image as opacities are recognizable and root canal treatments may significantly impede.
Due to their origin, some authors differentiate between real and fake . The real denticles are formed by odontoblasts , which, however, are not connected to the odontoblastic layer of the dentin . According to this, real denticles contain tubules. In contrast, fake denticles have no tubules. They are simple calcium deposits in the pulp tissue. What these hard substance formations have in common is the macroscopically spherical to nodular shape and the localization. Both initially arise freely in the pulp cavity. Over time, they can grow together with the dentin wall ( adherent denticles) or be enclosed by it ( interstitial denticles).
The existence of real denticles is not fully scientifically proven. The only indications are light microscopic specimens, which due to the preparation can only show a single cut through the tooth. Since no serial sections were made from the present specimens, it is conceivable that the structures designated as real denticles could be incised indentations in the dentin wall.
