Objectives: To undertake a blind caries and fluorosis prevalence study of Grade 1 (aged 5/6 yr) and Grade 4-7 (aged 8-12 yr) children from naturally water-fluoridated (1 ppm, since 1985) Burghead, Findhorn & Kinloss (F), and nearby nonfluoridated Buckie & Portessie (N-F), in rural Morayshire, Scotland, Methods: A blind clinical (+ 10% repeats) caries study of the above townships' 5/6-yr-old lifetime (15 F; 43 N-F), and 8-12-yr-old lifetime (55 F; 136 N-F)/schoollifetime (31 F; 37 N-F ) residents was undertaken following bussing of these children to a common examination site in close-by Elgin Town Hall Initially, each child was asked about their own perception of the aesthetics of their maxillary front teeth. Fluorosis was assessed clinically using the TF Index, as well as photographically--for later blind scoring (+ 10% repeats for lifetime 8-12-yr-olds) of slides by four dental and two lay 'jurors', alongside a now-established UK 'bench-mark' mildly mottled (TFI=2), fluorosis comparator slide, judged in previous studies to be aesthetically lay-acceptable. In addition, by parental questionnaire, information was sought concerning their child's fluoride supplement and dentifrice usage histories. Results: For 5/6-yr-olds, mean primary caries scores were 96.0% less in, fluoridated than nonfluoridated subjects (P < 0.01). In 8-12-yr-olds, DMFT values favoured water-fluoridated subjects; their caries-free trend was significant (P < 0.001 overall). Clinically, 33% of all lifetime F subjects and 18% of all N-F pupils had fluorosed maxillary anterior teeth (P =0.045), but no statistically significant difference was found between the 7% F and 3% N-F subjects with TFI scores >2 (P = 0.25). Photographically, 'jury' mottling assessment (+ 10% repeats) of projected slides resulted in at least 1:6 positive scores in 43.6% of F and 30.9% of N-F pupils, albeit they unanimously scored only nine F and five N-F children as having fluorosed teeth (P < 0.01). In no case... [ABSTRACT FROM AUTHOR]
