1 ABNORMALITIES of TEETH

2 Abnormalities of Teeth Environmental abnormalities of teeth Developmental abnormalities of teeth

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

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

5 Factors associated with tooth defects

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

7 Post developmental loss of tooth structure Attrition Abrasion Erosion Abfraction

8 Internal resorption Exteranal resorption

9 Environmental discoloration of teeth

10 Extrinsic stains Intrinsic stains

11 Localized disturbances in eruption Impaction Ankylosis

12 Developmental alterations of teeth

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

14 Developmental alterations in the size of teeth Microdontia macrodontia

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

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

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

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

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