Objectives To report the long‐term effect (18 years) of the Nexö‐method, initially implemented in groups of children in Moscow in 1994. Methods Three groups of children were included in the initial study in 1994. This study is a follow‐up study of two of the three initial groups: a group of 6‐year‐olds (test group 6 ; control group 6 ) and a group of 11‐year‐olds (test group 11 , control group 11) , n = 50 individuals in each of the four subgroups. In 2012, >80% of the participants in the two groups (now aged 24 and 28 years old) were re‐examined by the original examiner, who was blinded to which group the patients had belonged in the initial study. After re‐examination, the participants were interviewed by a person not otherwise attached to the study. Finally, caries data were collected from 100 24‐year‐olds and 100 28‐year‐olds who attended the dental school (50%) and private clinic (50%) in Moscow (External control groups 24,28 ). The outcome variables of the study were plaque and gingival status, and DMFT /S. Results In 2012, the control groups 24,28 displayed significantly higher plaque scores than the test groups 24,28 ( P ‐values < 0.05). No differences were seen regarding gingivitis scores ( P ‐values > 0.41). Mean DMFT /S in 2012 was test group 24 = 6.98/10.51, control group 24 = 8.84/13.14 ( P = 0.02/0.06). External control group 24 = 8.89/15.86 (test 24 versus external control group 24 , P = 0.01/0.007; control 24 versus external control group 24 , P = 0.94/0.16). Test group 28 = 6.74/10.83, control group 28 = 8.70/14.48 ( P = 0.02/0.008). External control group 28 = 9.03/18.06 (test 28 versus external control 28 , P = 0.03/0.001; control 28 versus external control 28 , P = 0.68/0.07). The interview indicated that the participants in the test groups were more aware of factors that are considered important for control of caries than participants in the control groups. Conclusions The data from this group of Moscow citizens suggest a long‐term positive effect of the Nexö‐method implemented during childhood.
