The prevalence and risk factors of gingivitis in a population of 6-year-old children in Iran

BACKGROUND AND AIM: Gingivitis is a reversible inflammation of gingival tissue. The prevalence of gingivitis is different in various communities. The aim of this study was to determine the prevalence of gingivitis among 6-year-old (± 3 months) children of Rayen, Kerman, Iran. METHODS: In this cross sectional study, 279 children (129 boys and 150 girls) from all Rayen’s nursery schools and primary schools were selected. Data collected through clinical examination with the consent of parents and teachers. Gingival Bleeding Index (GBI) was measured by using light and dental probe pressure. RESULTS: The prevalence of gingivitis was 37.8. There was statistically significant association between gender and gingivitis. Mouth breathing and toothbrush frequency were factors associated with gingivitis. CONCLUSION: This study showed relatively similar prevalence of gingivitis compared to other studies. The prevalence of gingivitis was more in boys than girls. Health educators and parents should have a more active role in children’s oral health education.
