Objectives: The aim of this study was to investigate the oral health of Nepalese schoolchildren relative to their sociodemographic characteristics.
Methods: This school-based, cross-sectional study was conducted among 5-6-, 12- and 15-year-old Nepalese children in 18 randomly selected districts of the 75 in Nepal. Clinical parameters were recorded according to the World Health Organization (WHO) guidelines. Results were presented as mean (SD) and proportions; the chi-square test, t-test and one way-ANOVA were also performed. The risk of dental caries in association with the place of residence was presented according to the outcome of a binary logistic regression analysis.
Results: The mean d-value for the 5-6-year-old children was 5.0 (4.22), which was higher than the mean D-values for the 12- and 15-year-old subjects, of 1.3 (1.77) and 1.9 (2.28), respectively. The youngest children, as well as children from the Kathmandu Valley, were likely to have more untreated caries lesions than children in the other age groups. The mean number of teeth with severe consequences of dental caries (pulpitis/ulceration/fistula/abscess or pufa/PUFA) was 1.3 (1.91) for the 5-6-year-old children, 0.1 (0.35) for the 12-year-old children and 0.3 (0.75) for the 15-year-old children. All age groups had gingival bleeding on probing in more than 15% of teeth. Children from rural locations had significantly more gingival bleeding than urban children. The same was true for 15-year-old girls compared with boys of the same age.
Conclusions: Among Nepalese children, oral diseases are common, and geographical variation is prevalent. The health policy should address the alarming oral health situation and need for urgent treatment and population-based preventive programmes that is evident in Nepal.
