Beskrivning: The aim of the present study is to explore the effects of preterm birth, postnatal complications and nutrition on development in primary teeth from children born <32 weeks of gestation and compare the results with previous studies of primary teeth from preterm infants born <29 weeks of gestation born ten years earlier. 
 
THE HYPTHESIS
 
1.     The mineral disturbances in primary teeth from infants born preterm during 1999-2002 coincide with morbidity, nutritional disturbances and medical interventions the first year of life.
2.     The frequencies of mineral disturbances differ microscopically between infants born before GA 29 weeks during 1988-1991 and infants born with a GA <32 weeks during 1999-2002.
3.     Increased protein intake during 1999-2002 compared with 1988-1991 will effect the enamel mineralisation.
