ABNORMALITIES of TEETH

Abnormalities of Teeth Environmental abnormalities of teeth Developmental abnormalities of teeth

Environmental alterations of teeth Developmental tooth defects Postdevelopmental structure loss Discolorations of teeth Localized disturbances in eruption

Visible environmental enamel defects can be classified into one of three patterns: Hypoplasia Diffuse opacities Demarcated opacities

Factors associated with tooth defects

Environmental effects on tooth structure development Turner hypoplasia Molar-Incisor hypomineralization Hypoplasia caused by antineuplastic therapy Dental fluorosis Syphlititic hypoplasia

Post developmental loss of tooth structure Attrition Abrasion Erosion Abfraction

Internal resorption Exteranal resorption

Environmental discoloration of teeth

Environmental discoloration of teeth Extrinsic stains Intrinsic stains

Localized disturbances in eruption Impaction Ankylosis

Developmental alterations of teeth

Developmental alterations in the number of teeth Anodontia Hypodontia Oligodontia Hyperdontia Supernumerary teeth Supplemental Rudimentary

Developmental alterations in the size of teeth Microdontia macrodontia

Developmental alterations in the shape of teeth Gemination Fusion Concrescence Accessory cusps Cusp of carabelli Talon cusp Dense evaginatus

Dense invaginatus(dense in dente) Type I Type II Type III Ectupic enamel Enamel pearls Cervical enamel extentions Taurodontism Hypercementation Dilaceration Supernumerary roots

Developmental alterations in the structure of teeth Amelogenesis imperfecta *Hypoplastic Amelogenesis Imperfecta Generalized pattern Localized pattern Autosomal dominant smooth pattern X-linked smooth pattern Rough pattern Enamel agenesis

*Hypocalcified Amelogenesis Imperfecta *Hypomaturation Amelogenesis Imperfecta Pigmented pattern X-linked pattern Snow capped pattern *Hypocalcified Amelogenesis Imperfecta *Amelogenesis Imperfecta with Taurodontism Hypomaturation-hypoplastic Hypoplastic-hypomaturation

Dentinigenesis imperfecta Hereditary opalescent dentin (type I) Brandywine isolate (Type II) Dentin dysplasia Dentin dysplasia type I (radicular dentin dysplasia-rootless teeth) Dentin dysplasia type II (coronal dentin dysplasia) Regional odontodysplasia (ghost teeth)
