Methods:
A programme was developed around the provision of anticipatory guidance to nulliparous women (women expecting their first child) in Adelaide. Mothers in the test group received oral health promotion information during pregnancy,
and later when the child reached 6 and 12 months of age. After the second round of information the test group mothers were randomized again. The information was reinforced in one of the test subgroups through a telephone consultation. There was no contact with mothers in the control group after enrolment. At the age of 20 ± 2.5 months all test and control group children were examined by a dentist. The case definition of an incidence of S-ECC was one or more upper incisor teeth being carious at the level of a cavitated or noncavitated lesion. The differences in S-ECC incidence between the test and control groups, and the test subgroups were analysed.
