Gingivitis in primary school children of Bangladesh

Though early diagnosis and intervention of gingivitis in school children can eliminate progression to frank periodontal diseases, no such measures in Bangladesh are in place to detect gingivitis at an early stage in school children. This survey was conducted in 2007 in the primary schools of rural, suburban and urban areas of Bangladesh to evaluate oral hygiene with special emphasis on gingivitis prevalent among 6-13 years school children. The clinical examination of the gingiva was carried out using a mouth mirror and a periodontal probe. A total of 1,820 primary school students (m/f = 946/873) took part in the investigation. The crude prevalence of gingivitis, AS* and plaque were 17.5%, 9.2% and 56.0% respectively. The prevalence of gingivitis was significantly higher in males than females (20.3 vs. 14.3%, p<0.001), lower than upper social class (21.1 vs. 12.6%, p<0.001) and in rural than urban plus suburban children (22.5 vs. 15.1%, p<0.001). Likewise, the prevalence of AS was higher in females, lower social class and rural children. Significantly lower prevalence of gingivitis, AS and plaque was found among those who used tooth brush and tooth paste than those who did not (15.4% vs 22.4%, p
