Foramen caecum dentis
The foramen caecum dentis (from Latin foramen "opening", "hole" and caecus "blind" and dens "tooth") is a blindly ending sometimes even ampoule-shaped invagination on the palatal surfaces of the upper incisors . This retraction is not always present, but on the other hand it is more pronounced on the lateral incisors ( teeth 12 and 22 ) than on the central ones ( teeth 11 and 21 ).
Hyperplasia of the inner enamel epithelium is responsible for this variant of the crown shape . In an extreme form, this “malformation” can lead to a real tooth anomaly , the dens invaginatus , which was previously also ( incorrectly from a histological point of view) referred to as the dens indente (tooth in the tooth) .
The predisposition to this anomaly or its expression is presumably genetic.
The foramen caecum dentis is a caries predilection site .
