El flúor, su relación con la salud bucodental, en niños de las parroquias rurales del cantón Cuenca, 2010

Abstract

OBJECTIVES: This is a descriptive research,which determines the prevalence of dental fluorosis and its risk factor.- POPULATION AND METHODS.- This research was made among 222 children,from 7 to 13 years old,who live at the rural parishes of Cuenca District.- We measured the fluor concentration in the water resources.We measured the fluor urinary excretion.Risk factors associated to dental fluorosis were looked for.- RESULTS: Schollars distribution according to their age,showed the following ranges:from 7 to 10years old,153 children(68.9%).From 11 to 13 years old: 69(31.1%).The distribution according to the gender was as follows:122(55%) male and a 100(45%)female. The prevalence of dental fluorosis is: 81.1%.The prevalence of dental fluorosis in relation to the level of fluorosis(Dean´s index) is as follows:Very light:23.4%,light 30.2%,moderate :23% and severe:4.1%.- Fluor contents i water ranges from:0.0 to 0.39 ppm.Low level content.- We did not find a significant difference:0,7,between dental fluorosis and fluor in urine when a chi square test was applied. Therefore quantifying fluor in urine is not good marker for detecting dental fluorisis .- CONCLUTIONS.- This research states that there is a high prevalence of dental fluorosis(81%)among 7-13 year old children who live at the rural parishes of Cuenca District.- In relation to the fluor content in water resources,the level was low:0,0-0,39 ppm..Fluor urinary excretion is not a good marker for fluorosis
