 Dental caries study, and cariogenesis research. Dental caries is defined as a "irretrievable disease of calcified teeth tissues, marked by demineralization of the inorganic portion and devastation of the tooth's organic material, which often results in cavitation". According to the anatomical site Pit and fissure caries: the pit and tooth fissures provide a place for the formulation of the carries. When the decay progresses, caries grow slowly deeper in the enamel nearest the surface of the tooth. Once the caries reach the dentin at the junction of the dentino-enamel, the decay spreads rapidly laterally. The decay follows a triangle pattern inside the dentin that points to the pulp of the tooth. This pattern of decay is typically described as tow triangles with their bases conjoined to each other at the dentino-enamel junction. According to progression: ACUTE cavity is that sort of caries that follows a rapid clinical course and leads to early pulpal involvement by carious process. Pain is more likely to be seen in acute cavity than chronic caries, but this is often not a tough and fast rule. CHRONIC DENTAL CARIES forms of caries that progress gradually and involve the pulp much longer than acute caries Often, the slow progression of caries gives sufficient time for dentinal sclerosis and tertiary dentin deposition in response to irritation. Pain isn't a prominent feature here thanks to the protection provided to the pulp by tertiary dentin formation.
