Penetrating caries , progression

When a caries progresses through the enamel to reach the dentin, it usually starts to present symptoms of pain. If the caries process is not controlled in time, it progresses to the dental pulp. This may be contaminated by microorganisms, even though the process may not be in direct contact with it, as contamination can occur through the dentinal tubules because the proteolytic enzymes produced by the bacteria degrade the collagen, increasing the diameter of the dentinal tubules, thus allowing the passage of the microorganisms into the pulp (8).
