 Material The study group will be recruited among the 2-year-old children that are regular patients attending the Public Dental Clinic in Rosengård, Malmö, Sweden. The clinic is situated in a multicultural suburban area with a low socio-economy. The proportion of immigrants is high in the area, the majority Arabic speaking. The inclusion criteria are i uncompromised general health, ii no cavities or severe dental diseases, and iii not mentally or physically disabled. Children that are uncooperative or totally reject dental examination are excluded. The children will be consecutively enrolled after signed informed consent verbal and written by their parents and assigned to either the test or the control group by pre-numbered envelopes generated by a computer program. As a new patient is entering the study, the clinician takes the next numbered envelope assigning the patient to either group A or B. The protocol has been subjected to the regional ethical committee and is approved.
