In Switzerland private practitioners carry out the school dental service for 2/3 of the about 850,000 5-16 years old pre-school and schoolchildren by contract with their community. In some bigger towns nearly 200 dentists are full-time employed at school dental clinics for the care of the remaining third of the children. In consequence of the success of preventive measures integrated into the school dental service the number of painful and stressful treatments has decreased. Therefore, the number of anxious children can decrease, too. As an example, in 1960, conservative treatment was 80% of the total work done by the school dental clinic of Basel, in 1986, may be assumed to have only 21%. A diversity of facts indicates that modern school dental service and improved oral health influences positively the later adult's dental behavior as well as his expectancies from the dentist with regard to preventive care.
