Purpose:
The aim of study was to investigate the oral health knowledge, attitudes and preventive practices of third grade school children in Harris County.
Methods:
In this cross-sectional study, oral health knowledge, attitudes, and preventive practices of the children were investigated by means of a self-administered, bilingual questionnaire. Three calibrated examiners collected data on dental caries, periodontitis, and fluorosis of 1,031 school children.
Results:
Most children reported "fairly adequate" oral hygiene habits (58%) and oral health knowledge (48%), and "adequate" dietary patterns (59%). Children with inadequate oral health knowledge were twice as likely to have caries than children with adequate knowledge (OR = 2.05, 95% CI = 1.29, 3.28). The mean combined DMFT/dft scores of children with inadequate knowledge were significantly higher than the mean for children with adequate knowledge (t = 2.6, P = 0.009).
Conclusions:
Results indicate a need to improve oral health knowledge and preventive practices among the study population. Because of the cross-sectional nature of the study, it is not possible to illustrate a cause-effect relationship between oral health education and prevalence of caries.
