Anodontia can be diagnosed when a baby does not begin to develop teeth around the age of 12 to 13 months or when a child does not develop their permanent teeth by the age of 10. The dentist can use a special X-ray, such as a panoramic image, to check if there are any teeth developing.
The incidence of neonatal teeth varies considerably, between 1:700 and 1:30,000 depending on the type of study; the highest prevalence is found in the only study that relies on personal examination of patients. [3] Natal teeth, and neonatal teeth, can be the baby's normal deciduous teeth, sprouting prematurely. [4]
Dental caries are the most significant cause of health problems among babies. The meta analysis of dental caries in children, a sample size of 80,405 was 46.2% (95% CI: 41.6–50.8%), and the prevalence of dental caries in permanent teeth in children in the world with a sample size of 1,454,871 was 53.8% (95% CI: 50–57.5%).
