Dental Anomallies and Disturbances in Development
| Dental Anomalies Terms | Dental Anomallies Definitions |
|---|---|
| Macrognathia | large jaws, usually the mandible results in class III malocclusion |
| Extoses | also called Torus, Extra bony growth in the midline of hard palate |
| Anomaly | any marked deviation from the normal |
| Heredity | a condition caused by genetic make up |
| Congenital | condition occurs before birth |
| Variation | mminor deviation from the normal |
| Macrodontia | abnormally large teeth |
| Hyperdontia | extra teeth |
| Andontial | mission teeth |
| Distomolars | "4th" molars, located distal to the max 3rd molars |
| Suplemental | resembles a regular tooth |
| Dens in Dente | "tooth within a tooth", mass of enamel and dentin within the pup |
| Flexion | distortion of the root portion only |
| Dwarfed Roors | normal sixe crowns with abnormally short roots |
| Fusion | 2 teeth jointed at the enamel and dentin (hard to floss) |
| Hypercementosis | excessive cementum formation |
| Enamel Pearls | small balls of enamel with a dentin core, *small masses of excess enamel |
| Hutchinsors Insisors | Peg-shaped teeth, usually associated with maternal syphillis |
| Muberry Molars | Irregular shaped molars with poorly formed cusps |
| Enamel Dysplasia | 2 types of enamel development, enamel hypoplasia, and enamel hypocalcification |
| Enamel Hypocalcification | Undercalcified enamel (thickness is ok, but is soft) |
| Enamel Hypoplasia | Incomplete or deficient development of enamel (thin enamel), inhibits enamel formation, may leave small pits/grooves at different levels in the crown, caused by inflammation, fever, systemic diseases, heredity |
| Amelogenisis Imperfecta | hereditary abnormaility in which there is enamel hypoplasia or enamel hypocalcification or both |
| Natal Teeth | Teeth present at birth |
| Neonatal Teeth | Teeth that erupt within the 1st 30 days of birth, *both natal and neonatal teeth lack root formation and shed or renew |
| Attrition | gradual and regular wearing away of incisal edges or cusps |
| Abrasion | wearing away of tooth by friction |
| Erosion | loss of tooth structure due to chemical demineralization in an area, eg. lemons, coke, bulimic patients |
