“…The very mild and mild forms of fluorosis have increased in the United States as compared with the prevalence 50 years ago [US Public Health Service, 1991], Ingestion of fluoridated toothpastes and mouthrinses by young children [Szpunar and Burt, 1987], prolonged use of infant formula prepared with fluoridated water [Bawden, 1992], and im proper prescription of fluoride supplements [Pendrys and Katz, 1989;Tate et al, 1990;Surovik et al, 1992] have been implicated in epidemiological studies as possible sources of fluoride responsible for the increased prevalence of fluoro sis. Other probable sources that contribute to fluoride intake include professionally applied topical fluorides [Ripa, 1991], foods prepared with fluoridated water that are trans ported to and consumed in nonfluoridated communities [Clovis and Hargreaves, 1988], and beverages such as tea that have a high fluoride content Opinya etal., 1991], Results obtained in this study show that depending on the brand, the kind of tea and its caffeine level, the fluoride con tent in tea infusions may vary over severalfold.…”
