Oral health status among 12 and 15 year old children from government and private schools in Hyderabad, Andhra Pradesh, India

Abstract

Background: The assessment of oral health status of children in government and private schools provide data on the oral health status of children from different socio‑economic background.
Aim: The aim of the following study is to assess and to compare the oral hygiene status, gingival status and caries experience between children from government and private schools in Andhra Pradesh, India.
Subjects and Methods: A combination of cluster and stratified random sampling was employed to select the study participants. Oral hygiene status, gingival status and caries experience was assessed and compared among 12‑and 15‑year‑old children from three government and private schools each. The examination was carried out by three trained and calibrated investigators using a mouth mirror and explorer under natural daylight.
Results: A total of 604 children (331 government and 273 private) were examined in the study. The mean oral hygiene index‑simplified (OHI‑S) was higher among government school children (2.9 [1.1]) compared private school children (0.6 [0.4]). The mean gingival score and mean decayed missing filled teeth were also higher among government school children compared with private school children. A significantly higher number of children in the government schools had poor oral hygiene status, moderate to severe gingivitis and caries experience.
Conclusion: The prevalence of oral diseases was relatively less among children from private schools in comparison with those from government schools. Hence, the children from government schools should be given the priority compared with private school children in any school dental health programs planned on a statewide basis.
