Does the neonatal intubation cause defects in primary teeth of premature infants?
Tracheal intubation in the neonatal period is the main cause of enamel defects in primary teeth of children born preterm. The longer the duration of intubation, the greater the chance of developing dental enamel defect. The area of action during movement of the laryngoscope toggle corresponds to the region most affected by tooth enamel hypoplasia in children intubated, upper right central incisor, lateral incisor and upper left.
