Table 3 Medical health problems (chronic illness, general health problems and daily medication) in extremely preterm (EPT), very preterm (VPT), and full term-born adolescents at 12–14 and 17–19 years of age.

Further, participants with experience of orthodontic treatment and claimed orthodontic treatment need in extremely preterm (EPT), very preterm (VPT) and full term-born adolescents at 17–19 years of age
