As one would expect, the neonatal line is found in all primary teeth and in the larger cusps of the permanent first molars.
2.
The neonatal line marks the stress or trauma experienced by the ameloblasts during birth, again illustrating the sensitivity of the ameloblasts as they form enamel matrix.
3.
These lines are formed in Enamel and dentine at the point of birth . Therefore, only teeth that are developing at birth can exhibit neonatal lines.
4.
In forensic dentistry, the neonatal line can be used to distinguish matters such as if a child died before or after birth and approximately how long a child lived after birth.
