Natal teeth are teeth that are present above the gumline (have already erupted) at birth, and neonatal teeth are teeth that emerge through the gingiva during the first month of life (the neonatal period). [1][2] The incidence of neonatal teeth varies considerably, between 1:700 and 1:30,000 depending on the type of study; the highest prevalence ...
Natal and neonatal teeth are an anomaly that involves teeth erupting in a newborn infant's mouth earlier than usual. The incidence ranges from 1:2,000 to 1:3,500 births. Natal teeth are more frequent, approximately three times more common than neonatal teeth. Some authors reported a higher prevalence in females than males.
Cleft lip and/or palate is a congenital abnormality that is seen frequently around the world. On average, about 1 in every 500-750 live births result in a cleft (Hardin-Jones, Karnell, & Peterson-Falzone, 2001). Furthermore, in the U.S., the prevalence for cleft lip with or without cleft palate (CL +/- P) is 2.2 to 11.7 per 10,000 births.

The neonatal line is darker and larger than the rest of the striae of retzius. The neonatal line is the demarcation between the enamel formation before birth and after birth i.e., prenatal and postnatal enamel respectively. [1] It is caused by the different physiologic changes at birth and is used to identify enamel formation before and after ...
Early childhood caries. Early childhood caries (ECC), formerly known as nursing bottle caries, baby bottle tooth decay, night bottle mouth and night bottle caries, is a disease that affects teeth in children aged between birth and 71 months. [1][2] ECC is characterized by the presence of 1 or more decayed (non cavitated or cavitated lesions ...
