Dental Anomallies and Disturbances in Development

Dental Anomalies TermsDental 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
