Prenatal factors can cause anomalies in development of teeth and jaws. Which option lists a prenatal etiological factor?

• A. Anomalies in development of teeth and jaws
• B. Breathing disturbances
• C. Swallowing disturbances
• D. Discrepancy between sizes of jaws and teeth

Answer: (A)

Prenatal influences that shape how teeth and jaws form can lead to congenital abnormalities. The option describing anomalies in development of teeth and jaws fits as a prenatal etiological factor because such anomalies originate during prenatal life and reflect altered morphogenesis. Breathing disturbances, swallowing disturbances, and a mismatch between jaw and tooth sizes are postnatal or functional issues that arise after birth and do not represent prenatal etiological factors.
