The dental care habits of parents and children as well as the associat
ions of these habits were investigated in a follow-up study conducted
in the Southwest of Finland. The background factors of the child's use
of night-time juice were also studied. The families of the study were
a representative sample of local young families with their first chil
d. The study sample was obtained using stratified randomized cluster s
ampling and confidential questionnaires. Both the mother's and the fat
her's toothbrushing habits were significantly associated with the chil
d's toothbrushing habits with a cumulative effect. The mother's use of
sugar was significantly associated with the child's sugar use habit.
Infectious diseases at the age of 9-17 months had an increasing effect
on the use of juice at night. Fathers and the youngest mothers, espec
ially, need additional support not only for the demanding task of the
upbringing of their child but also for the care of their own teeth.
