Abstract

The objetive .of study to asses the prevalence of caries and related factors in the infant population of Móstoles. We conducted a crossover descriptive in 363 six years old schoolchildren in Schools included in the San Fernando Health Center influence area We conducted a dental exploration using the World Health Organization criteria. Variables such as dental state teeth brushing habits, and social-demographic aspects were collected. Results for year 1997 were compared to those obtained in the same schools in year 1988. The prevalence of caries in 1997 for deciduous dentition is 24.6% and for ermanent dentition 1.1%. The non adjusted analysis shows that the schoolchildren revised in 1988 have an OR for suffering caries of 3.48 compared to those studied in 1997. Low social class is also a risk factor for caries OR=1.61(IC95% 1.19-2.17)with respect to median-high class. In conclusion,. the prevalence of caries in the infant population of Mostoles has decreased between 1988 y 1997. This reduction is related to an improvement in the social class of the scholars. The frequency of teeth brushing has also improved during this period but is not associated to the decrease in the prevalence of caries in this work.
