Diseases of hard tissues of teeth

Dental caries
- localized destruction of calcified tissue initiated on the tooth surface by decalcification of the enamel of the teeth, followed by enzymatic lysis of organic structures, leading to cavity formation that, if left untreated penetrates the enamel and dentin and may reach the pulp.
- The decay of a tooth, in which it becomes softened, discolored, and/or porous.

Unspecified dental caries
- localized destruction of calcified tissue initiated on the tooth surface by decalcification of the enamel of the teeth, followed by enzymatic lysis of organic structures, leading to cavity formation that, if left untreated penetrates the enamel and dentin and may reach the pulp.
- The decay of a tooth, in which it becomes softened, discolored, and/or porous.

Dental caries limited to enamel
- A chalky white area that appears on a tooth surface indicating the presence of decalcified enamel and the potential to advance to cavitation.

Pathological tooth resorption
- resorption of calcified dental tissue, involving demineralization due to reversal of the cation exchange and lacunar resorption by osteoclasts.
