Dental Anomalies: an Updated Review on Development, Morphology, and Clinical Management

Changes in the number, size, shape, structure, and eruption of teeth constitute dental anomalies. Disorders that occur after teeth have completed their normal formation are called “acquired dental anomalies,” while disorders that occur during the tooth formation process are defined as “developmental dental anomalies.” Developmental anomalies can be caused by genetic factors such as heredity, metabolic disorders, and mutations, and/or environmental factors including physical, chemical, and biological factors. These anomalies can also occur as a symptom of a disease or syndrome, and early diagnosis can be significant for the treatment of the associated disease or syndrome.
