Abstract

The aim of this study was to report the dental caries and gingivitis prevalence and to identify the risk indicators of those diseases among socioeconomic, clinical variables and the gender in 5-year-old preschool children from Piracicaba, Brazil, in 2005. The sample consisted of 728 preschool children, both genders, attending 22 public (n=428) and 18 private (n=300) preschools. Clinical examination was performed by one previously calibrated examiner, at the back yard, under natural light, using dental mirror, CPI probe, air drying and previous tooth brushing. The dental caries was measured using dmft and dmfs indexes and the gingivitis, by alteration gingival index. Initial caries lesion (IL) was also evaluated. The socioeconomic variables (monthly family income, number of people living in the household, parents¿ educational level, home ownership and householder¿s occupation) were collected by means of a parental semi structured questionnaire. The risk indicators of dental caries and gingivitis were determined using multiple logistic regression analyses at 5% significance level. The mean values for dmft and dmfs indexes were 1.30 (SD=2.47) and 3.08 (SD=7.55) respectively, being 62.2% of the children were caries free. The risk indicators identified were father¿s incomplete undergraduate studies and presence of initial lesion. The prevalence of gingivitis was 16.6%, while the risk indicators were studying at public preschool, living with more than four people, being male or presenting initial caries lesion. In conclusion, children who presented initial caries lesion and whose fathers had incomplete undergraduate studies were presented more chance of caries. Moreover, studying at public preschool, living with more than four people, being male or presenting initial caries lesion were risk indicators of gingivitis (AU)
