Definition
Localized microbial disease affecting post eruptive tooth by demineralizing its inorganic content and destruction of its organic content.
Pathology of dental caries
Microscopic appearance
Histopathology of DENTIN caries
Superficial zone
Infected lesion
Liquefaction foci and transverse clefts
Beading
Bioneers
Uninfected lesion
Zone of hypomineralization
Zone of hypermineralization
Zone of fatty degeneration
Histopathology of ENAMEL caries
Phase of secondary enamel caries
Phase of destruction
Phase of bacterial invasion
Phase of initiation
Macroscopic appearance
White chalky spot Then becomes Brown spot
