Abstract

Fluoride has been associated with remineralisation of skeletal tissues. However, excess consumption of fluoride may lead to malformation of the skeletal tissues; namely skeletal and dental fluorosis. Exposure to fluoride mainly comes from drinking water and it is excreted mainly through urine. Therefore, the aim of this study was to study the exposure to fluoride in drinking water and the prevalence of dental fluorosis among 12-years old students in a rural area of Sepang, Selangor. Selected students (N=41) were asked about their past and current exposure information. Three days sample of urine and drinking water were collected to find the mean of current exposure to fluoride. The severity of dental fluorosis was determined using Total Score Index of Fluorosis (TSIF). It was found that the mean of urinary fluoride was 1.49±0.320 while the mean of fluoride in drinking water was 0.51±0.099. The prevalence of dental fluorosis was 51.3%; which consists of score 0 with 48.8%, score 1 and 2 with 22% respectively, score 3 with 2.4% and score 4 with 4.9%. The mean of dental fluorosis score was 0.93±1.13. The mean score for respondents who were breastfed for less than 12 months was 1.2l± 1.04 while for the respondents who were breastfed for more than 12 months was 2.72±2.78. There was no significant relationship between fluoride in drinking water and the score of dental fluorosis (r=¬0.329, p<0.05 and also there was no significant relationship between urinary fluoride and dental fluorosis score (r=-0.060, p>0.05). It can be concluded that fluoride exposure through drinking water was not the major factor of causing dental fluorosis in this study. Breastfeeding could not be seen as a protective factor against the occurrence of dental fluorosis in this study. Keywords: Fluoride, Dental Fluorosis, urine, drinking water, breastfeeding
