The so-called eruption sequestrum.
The literature relating to so-called eruption sequestra is reviewed. Two cases in which there were calcified fragments adjacent to the crowns of all four first molars are described. Histologic evidence suggests that these calcified fragments consist of a cementum-like substance formed within the follicle, and not sequestrated bone.
