Summary
This study examined natal and neonatal teeth in 9,600 infants, finding premature eruption of normal primary incisors. These immature teeth presented with normal crowns but minimal root development.
Area of Science:
- Pediatric Dentistry
- Neonatal Health
- Oral Development
Background:
- Natal teeth (present at birth) and neonatal teeth (erupting within the first month) are rare occurrences.
- These teeth can pose risks such as feeding difficulties and injury to the infant or mother.
- Understanding their prevalence and characteristics is crucial for appropriate clinical management.
Purpose of the Study:
- To determine the prevalence of natal and neonatal teeth in a large cohort of newborns.
- To describe the clinical and histological characteristics of these prematurely erupted teeth.
Main Methods:
- A prospective study involving 9,600 infants delivered at a maternity hospital.
- Clinical examination of all infants to identify the presence of natal or neonatal teeth.
- Detailed description of the morphology and root formation of identified teeth.
- Histological examination of representative tooth samples.
Main Results:
- The prevalence of natal and neonatal teeth was determined within the study population.
- The identified teeth were confirmed as prematurely erupted primary incisors.
- Crowns exhibited normal shape and size, while root formation was minimal.
- Histological analysis revealed immature dental tissue.
Conclusions:
- Natal and neonatal teeth are premature eruptions of primary incisors with immature histological features.
- Further research is needed to establish standardized management protocols for these cases.
