A longitudinal study of oral health in immigrant children in Sweden.
Children immigrating into Sweden from Finland and Southern Europe (Greece, Yugoslavia and Turkey) were subjected to a longitudinal study on caries activity and gingival condition. For each immigrant child a Swedish "twin" of the same sex and age was used as a control. Out of 124 pairs originally examined, 75 were reexamined after a 2 1/2-year stay in Sweden. The study showed that on arrival in Sweden the Finnish children had more caries and a higher Gingival Index (GI) than the controls and that they acquired more carious lesions during their stay in this country. Their GI, however, did not develop less favorably than that of the Swedish controls. The South-European children did not seem to have more carious lesions than the Swedish controls on arriving, nor did they seem to acquire more carious lesions during the period of observation. Their GI was higher at the first examination but the change in this index ran parallel with that of the controls. It was concluded that the children immigrating from Finland should be considered a risk group with regard to oral health.
