Maternal knowledge, dental service utilization and self-reported oral hygiene practices in relation to oral health of preschool children in Lagos, Nigeria

Abstract

INTRODUCTION: Maternal oral health practices and perception about infant oral health are probable pointers to the status of an infant´s oral health. We aimed to evaluate maternal knowledge about infant oral health and oral hygiene practices. METHODS: a descriptive study was conducted among 334 mothers using a cluster sampling technique. A 32-item pretested validated, interviewer administered questionnaire obtained socio-demographic data, pattern of dental service utilization, maternal and child oral hygiene practices and to assess oral health related knowledge. Linear regression analysis was conducted to assess predictors of knowledge scores, p ≤ 0.05 was accepted as statistically significant. RESULTS: only 42 (12.6%) knew how a baby´s mouth should be cleaned while 127(38%) knew that cariogenic bacteria was transferrable. The mean knowledge score was 4.89 ± 1.72 out of 9. There was a moderate positive significant correlation (0.334; p<0.000) between maternal educational level and having good knowledge. Multiple linear regression analysis revealed that the knowledge score was significantly associated with mother´s oral hygiene practices (β=0.167; 95% CI; p<0.001), education level (β=0.321; p<0.000).
