Abstract

This study was designed to determine the association between oral hygiene status and necrotizing ulcerative gingivitis (NUG), as well as the severity of NUG in Nigerian children. The study cohort was made up of 438 children under 12 years attending the Dugbe Dental Centre in Ibadan, Nigeria. A dental history and intra-oral examination using probe and mirror were taken. A slightly modified Green and Vermillion index was used to determine oral hygiene status. An index was also developed for NUG severity. The result showed that only 2.4% of the children with good oral hygiene had NUG, compared with: 24.6% of those with fair oral hygiene; 62.8% of those with poor oral hygiene; and 66.7% of those with very poor oral hygiene. The prevalence of the more severe stages of the disease showed an increasing trend as the oral hygiene status became poorer. This study thus demonstrated that the prevalence of NUG was significantly higher and more severe in children with poor oral hygiene status compared with those having good oral hygiene status. (P < 0.001).
