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 |
