Oral mucosal conditions in preschool children of low socioeconomic status: prevalence and determinant factors.

Abstract
The aim of the present study was to determine the prevalence of oral mucosal conditions and associated factors among 541 preschoolers of low socioeconomic status. A cross-sectional study was carried out. Sociodemographic data and information on harmful oral habits were gathered with the use of a questionnaire. A clinical exam was performed for the determination of oral mucosal conditions, dental caries and level of oral hygiene. Data analysis involved statistical analysis, the Kruskal-Wallis test, Mann-Whitney test, chi-square test, Fisher's exact test and multivariate regression (p < 0.05, 95 % CI). The prevalence of oral mucosal conditions was 40.7 %. The most prevalent oral mucosal conditions were coated tongue (23.4 %), melanotic macules (14.4 %), oral ulcers (11.8 %), Fordyce's spots (8.1 %), angular cheilitis (3.0 %), geographic tongue (2.8 %), linea alba (1.5 %) and fistula (1.3 %). Children between 3 and 5 years of age had a greater chance of exhibiting coated tongue (OR, 2.55; 95 % CI, 1.6-4.1), melanotic macules (OR, 4.07; 95 % CI, 2.3-7.2) and Fordyce's spots (OR, 12.70; 95 % CI, 7.2-28.6). The female gender had a greater chance of exhibiting melanotic macules (OR, 2.23; 95 % CI, 1.3-1.8). Coated tongue was more prevalent among children from low-income families (OR, 2.35; 95 % CI, 1.3-4.3) and those with inadequate oral hygiene (OR, 4.65; 95 % CI, 2.9-7.4). Caries constituted a predictive factor for oral ulcers (OR, 2.15; 95 % CI, 1.2-3.9) and fistula (OR, 12.00; 95 % CI, 1.4-11.3). Bruxism (teeth clenching/grinding) was a predictive factor for angular cheilitis (OR, 5.55; 95 % CI, 1.9-16.3). The determinant factors for oral mucosal conditions were the female gender, age between 3 and 5 years, inadequate oral hygiene, low household income, residence in rural areas and presence of dental caries and bruxism.
