Primary factors for the cause of dental caries
Primary factors in etiology of dental caries
there are also various theories that have been formulated
Dental caries is a multifactorial disease in which there is an interplay of three principal factors.
1) Host ( tooth)
2) Agent (flora)
3) Environment (substrate)
When these three essential factors for dental caries exist in an individual for a considerable time, then dental caries may develop. The tooth is the target tissue that is destroyed in the dental caries process.
The cariogenic oralflora is the agent that produces and secretes the chemical substances ( organic substances, chelating agent and proteolytic enzymes) that cause the destruction of the inorganic components and the subsequent breakdown of the organic content of the enamel and dentin. The local substrate provides nutritional and energy requirement for the oral microflora, there by permitting them to colonize, grow, and metabolize on selective surfaces of the teeth.
