Question

Quizplus · Accepted Answer

The dark,arclike areas in a stained histologic section in a tooth are considered interglobular dentin.In these areas,only primary mineralization has occurred within the predentin,and the globules of dentin do not fuse completely.Tomes granular layer is most often found in the peripheral part of dentin beneath the root's cementum.Mantle dentin is the first predentin that forms near the dentinoenamel junction.Deep to the mantle dentin is the layer of dentin around the outer wall of pulp,the circumpulpal dentin,which makes up the bulk of the dentin in a tooth.
