Abstract :

 Neonatal line (NNL) is a prominent microscopic feature which separates the enamel formed during intrauterine life from that formed in extrauterine life. The aim of the present study was to calculate the average width of the NNL in the first permanent molar enamel of 10 children. Out of which five were born to mothers with normal gestational week (≤39) and five were born to mothers with lesser/reduced gestationalweek (≥37). The parents of the children were given questionnaire containing questions about the course of pregnancy. All collected teeth were sectioned in the mesiodistal direction using an aasive Lathe wheel and examined under a light microscope. The average width of the NNL in children born with reduced gestational week was thicker compared to the children born to normal gestational week. In conclusion this study suggests that the length or duration of the gestational week is responsible for the degree of expression of the NNL.
