Study Notes
Developmental Anomalies
- Microdontia: small teeth, small jaw, proportional in size, fewer teeth, and normal thickness of enamel and dentin.
- Anodontia: absence of teeth, can be true (congenital) or pseudo (failed eruption due to systemic disturbances).
- Macrodontia: large teeth, large jaw, proportional in size, and larger pulp chamber and canal.
Varieties of Macrodontia
- True Generalized Macrodontia: big teeth, big jaw, proportional in size, and larger pulp chamber and canal.
- Relative Generalized Macrodontia: normal-sized teeth, normal-sized jaw, and fewer teeth.
- Macrodontia of a Single Tooth: peg-shaped lateral incisors or central incisors.
Anodontia
- True Anodontia: congenital absence of teeth.
- Pseudo Anodontia: failed eruption of teeth due to systemic disturbances (e.g., hypo-function of pituitary/thyroid gland, dystosis, Crouzon syndrome).
- False Anodontia: missing teeth due to extraction.
Etiology of Anomalies
- Hereditary ectodermal dysplasia (tooth buds didn't form or odontogenesis didn't happen).
- Hyperpituitarism (overactive pituitary gland).
- Inheritance and hormonal imbalance.
- Atavism theory (teeth are lost due to the process of evolution).
Other Anomalies
- Paramolar Tubercle: a type of macrodontia with a resemblance to a tooth in a tooth.
- Mulberry Molars: dwarfed, rough, and hypo-plastic crowns with thin enamel and prominent dentin.
- Enamel Pearls: anomalies in shape and form.
- Anomalies in Root: unusually large or small roots, short truncated roots, or extra long roots.
