    CLASSIFICATION OF DENTAL ANOMALIES TYPES OF DENTAL ANOMALIES HYPOPLASTIC: ·Hypodontia Reduction of number or incomplete ·Microdontia development of teeth, with structural,
    morphological and/or functional alterations.
    HYPERPLASTIC: ·Supernumerary tooth Increase in number of teeth or increase of ·Supernumerary root tissue components, with structural,
    morphological and/or functional alterations.
    ·Taurodontism HETEROTOPIC: ·Dilaceration Eruption and/or position of the teeth ·tooth torsion outside their usual place or by the ·tooth transposition displacement and development of dental
    tissues with loss of normal relation between
    ·tooth transmigration
    ·Invaginated tooth
    ·Impacted tooth
