– Purpose: In 1987, Jamaica initiated a comprehensive island‐wide salt fluoridation program. A survey was conducted in 1995 to monitor the impact of salt fluoridation among children in Jamaica. Methods: Dental examinations of 1120 children aged 6–8, 12, and 15 years were conducted according to World Health Organization criteria to assess dental caries, fluorosis, the presence of and need for dental sealants, and Community Periodontal Treatment Needs (CPI). Results: Age specific DMFT means observed in 1995 were 0.2 at age 7, 0.4 at age 8, 1.1 at age 12 and 3.0 at age 15. The mean DMFT scores in children 6, 12 and 15 years of age were dramatically lower than the corresponding scores of 1.7, 6.7 and 9.6 obtained at the baseline examination in 1984 for children of the same age groups, respectively (baseline data for 7‐ and 8‐year‐olds were not collected). The mean percentage of sound permanent teeth for all age groups was 90% in 1995. The percentage of children caries‐free at baseline was 27.6% for 6 years, 2.8% for 12 years and 0.3% for 15 years of age. In 1995, the percentage of caries‐free children (permanent teeth) was 61%. In 1984, 23 children were scored as having very mild or mild fluorosis. In 1995, five children were scored in the same categories of fluorosis, using Dean’s criteria; thus, fluorosis remained at negligible levels in 1995. Conclusions: The oral health survey conducted in Jamaica in 1995 indicated a significant decline in dental caries compared with findings in 1984. The major change in Jamaica during the interval was the introduction of salt fluoridation in 1987. Dental fluorosis was low in the 1995 survey.
