Week 17: Interpretation of Developmental Disturbances

impacted teeth

occur when one tooth is prevented from erupting due to being wedged up against a neighbouring tooth

embedded teeth

tooth not erupting due to being trapped under bone or blocked by gums - lack force necessary to erupt

familial tendency

when an anomaly occurs more frequently than usual in one family

developmental anomaly

when the condition results during the formation and development of a dental structure

hypodontia

congenital absence of teeth in primary and/or permanent dentition; most common etiology is hereditary

odontoma

tumerous anomaly of calcified dental tissues; complex and compound

osteogenesis imperfecta

genetic disorder in which bones break easily and sometimes for no reason - can lead to weak muscles, brittle teeth, curved spine, hearing loss; caused due to a gene defect that affects how the body produces collagen

taurodontism

morphologic abnormality of teeth; aka bull teeth; most conspicuous in the molar teeth; distance from the roof of the pulp chamber to the root bifurcation is greatly increased
