ABSTRACT
BACKGROUND: Oral hygiene is essential for low caries or gingivitis prevalence in children. This study aimed to determine the oral hygiene profile of children from secondary schools (10-17 years) in Bucharest, Romania, and to explore options for preventing their future oral diseases. METHODS: The study was cross-sectional, with a sample of n = 1595 pupils. The sample was stratified by clusters in city areas, grades, and the criterion of the presence/absence of in-school dental service. Dental check-ups were performed by using a commune dental examination kit. The oral hygiene simplified index (OHI; Silness and Löe) was used to assess the children's oral hygiene status. Five questions were used to determine oral hygiene habits. RESULTS: The mean value of the OHI was 1.04. Some differences in oral hygiene scores were found for different socioeconomic variables, such as parents' education (p < 0.05): parents with vs. without a university degree-0.95/0.94 (male/female) vs. 1.06. Most of the children used manual toothbrushes (88%). CONCLUSIONS: The analysis of objective data (OHI) revealed a good level of oral hygiene, with many socioeconomic disparities.
