This study was undertaken to examine the effects of intubation on the
enamel development of primary teeth in children intubated during the f
irst 3 months of life. The teeth of 35 children were examined clinical
ly for signs of defects. Dental enamel defects were seen in 26 (74%) p
atients; enamel hypoplasia was seen in 15 and enamel hypomineralizatio
n in 19 cases. In eight patients both enamel hypoplasia and hypominera
lization were found. There was a preponderance of enamel defects in th
e right maxilla, which supports the hypothesis that an early trauma to
mineralizing primary teeth caused by laryngoscope may lead to dental
enamel hypoplasia.
