Overview
Dentin represents a mineralized hard tooth tissue which forms the core of clinical tooth crown and root. The dentin tissue is filled with numerous dentinal tabules whose lumens contain cytoplasmic processes of odontoblasts. If the tooth surface is protected by the layer of enamel and cement, the dental pulp is isolated from external environment. If the layer of enamel or cement is damaged, dentin and dental pulp are exposed to the environment of oral cavity and therefore to penetration of bacteria and their toxins. The objective of the experimental study was to determine, on the basis of penetrating organic dye, the possibility of penetration of foreign compounds across the root wall.
Key words:
tooth cement - radicular dentin permeability - bacterial infection
