The aim of this natural experiment was to investigate whether lifetime access to fluoridated water is associated with dental caries experience among adults from Florian\u00f3polis, Brazil. The data originated from a population-based cohort study ( EpiFloripa Adult) initiated in 2009 ( n = 1,720) when participants were aged 20 to 59 years. The second wave was carried out in 2012 ( n = 1,140) and included a dental examination and a face-to-face questionnaire. Participants residing at the same address since the age of 7 y or before were included in the primary analyses. Sensitivity analyses were also performed. WF was implemented in the city in 2 different periods of time: 1982 (60% of the population) and 1996. Dental caries was assessed by the decayed, missing, and filled teeth (DMFT) index. A combination of residential status, participant\u2019s age, and year of implementation of WF permitted the creation of participants\u2019 lifetime access to fluoridated water: &gt;75%, 50% to 75%, and &lt;50% of a participant\u2019s lifetime. Covariates included sex, age, socioeconomic mobility, educational attainment, income, pattern of dental attendance, and smoking. Participants who accessed fluoridate water &lt;50% of their lifetime presented a higher mean rate ratio of DMFT (1.39; 95% CI, 1.05\u20131.84) compared with those living &gt;75% of their lifetime with residential access to fluoridated water. Participants living between 50% and 75% and &lt;50% of their lives in fluoridated areas presented a decayed and filled teeth mean ratio of 1.34 (95% CI, 1.02\u20131.75) and 1.47 (95% CI, 1.05\u20132.04) higher than those with residential access to fluoridated water &gt;75% of their lifetime, respectively. Longer residential lifetime access to fluoridated water was associated with less dental caries even in a context of multiple exposures to fluoride.<\/jats:p>","DOI":"10.1177\/0022034516643064","type":"journal-article","created":{"date-parts":[[2016,4,7]],"date-time":"2016-04-07T01:30:42Z","timestamp":1459992642000},"page":"868-874","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":36,"title":["Access to Fluoridated Water and Adult Dental Caries"],"prefix":"10.1177","volume":"95","author":[{"given":"M.A.","family":"Peres","sequence":"first","affiliation":[{"name":"Australian Research Centre for Population Oral Health, The University of Adelaide, Adelaide, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K.G.","family":"Peres","sequence":"additional","affiliation":[{"name":"Australian Research Centre for Population Oral Health, The University of Adelaide, Adelaide, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.R.","family":"Barbato","sequence":"additional","affiliation":[{"name":"Postgraduate Program in Public Health, Federal University of Santa Catarina, Florian\u00f3polis, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D.A.","family":"H\u00f6felmann","sequence":"additional","affiliation":[{"name":"Department of Nutrition, Federal University of Parana, Curitiba, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2016,4,6]]},"reference":[{"key":"bibr1-0022034516643064","unstructured":"Ag\u00eancia Reguladora de Servi\u00e7os de Saneamento B\u00e1sico do Estado de Santa Catarina (AGESAN). 2015.
