The genetic basis of dental anomalies and its relation to orthodontics.

The interruption of odontogenesis by any etiological factor may result in dental anomalies. Apart from the environmental factors, the impact of genetics in dental anomalies was found to be a factor in different levels. Many authors had questioned a common genetic defect resulting in different phenotypic conditions such as absent, malformed, malposed or ectopic teeth.

Interdisciplinary treatment of a patient with bilateral cleft lip and palate and congenitally missing and transposed teeth.

The comprehensive treatment of a patient with cleft lip and palate requires an interdisciplinary approach for functional and esthetic outcomes.
