Dental traumatic injuries are very common and occur frequently in children at an early age. Epidemiological studies have shown a frequency of approximately 30% of primary dentition that is affected by trauma. The close relationship between the apices of primary teeth and germs of the permanent successors can lead to developmental disturbances in the permanent dentition. Development disturbances in permanent teeth caused by trauma in their predecessors have a prevalence that ranges from 12 -74%.

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...
