This video is about a dentin bridge I found during a root canal re-treatment of an upper seven molar. Every time I found them I like to preserve these structures to avoid tooth weakening. Only with the help of the microscope we can distinguish these kinds of formations from pulp stones. In this case the bridge was crossing the palatal canal.
What is great in man is that he is a bridge and not a goal.
