Anodontia: failure of teeth to develop (same as agenesis of teeth) Hypodontia: having less than 6 congenitally missing teeth.(partial anodontia) Oligodontia: having 6 or more congenitally missing teeth. H Hyperdontia: extra t th same as d ti t teeth, supernumerary teeth, may be singleor multiple as in CCD.

(Hereditary amelogenesis imperfecta) (rampant caries) (attrition) -- Hypoplastic type -- Hypocalcified type -- Hypomaturation type
Hypoplastic type
Inadequate formation of enamel matrix, both pitting and smooth types exist. Enamel may be reduced in quantity () but is of normal hardness.
25
2008/12/10
Hypocalcified type
Aefect not in the quantity but in the quality() of enamel. It is poorly mineralized, soft and chips and wears easily.
Hypomaturation type
A defect in the crystal structure of enamel leads to a mottled enamel with white to brown to yellow colors.
