Oral manifestations in preterm-born children
Premature birth can cause enamel defects, usually on the primary teeth, although permanent teeth can also be affected. Causes of enamel defects include calcium disturbances in the neonatal period and local trauma from laryngoscopic and endotracheal intubation. Pressure from the tube can also result in other defects, such as palatal grooving, high arched palate and palatal asymmetry. The altered palatal morphology can lead to an increase in malocclusions, such as crossbite, resulting in an increased need for orthodontic treatment. Deep bite is another common malocclusion trait in preterm children. Prematurity should be taken into account when estimating time for teeth eruption or planning for orthodontic treatment in these children. Dentists should be aware of the birth status of their paediatric patients and pay special attention to prematurely born children.
