Abstract Purpose: The purpose of this study was to investigate risk factors for enamel hypoplasia (EH) and enamel opacity (EO) in the permanent teeth of healthy schoolchildren from a nonfluoridated community in Australia. Methods: Children with EH (N=104) or EO (N=104) were compared with matched controls without enamel defects (N=105). Subjects who previously resided in an optimally fluoridated town provided data on the effects of drinking fluoridated water. Results: The main risk factors for EH were low socioeconomic status (P<.04), respiratory infections (P<.001), exposure to cigarette-smoking (P=.001), asthma (P=.007), otitis media (P=.01), urinary tract infection (UTI; P=.03) and chickenpox (P=.001). Combinations of either chickenpox and UTI or chickenpox and exposure to cigarette-smoking were associated with relatively high numbers of EH. While use of adult toothpaste (1,000 ppm) at 0 to 3 years old increased risks for EH, there were less EO in children who used child toothpaste (300 ppm fluoride; 86% vs 95%; P=.02) or who drank optimally fluoridated water compared to those who did not (4% vs 29%; P<.001). Conclusions: Children with low socioeconomic status, histories of respiratory or chickenpox infections, exposure to cigarette-smoking, urinary tract infections, otitis, and use of adult toothpaste are predisposed to enamel hypoplasia. By contrast, drinking optimally fluoridated water at 0 to 3 years old reduces the risk for enamel opacities.
