HITA IGLESIAS, Cristina et al. Impact of public preventive programmes on oral quality of life of 11 to 12-yr-old school students. Med. oral patol. oral cir.bucal (Internet) [online]. 2007, vol.12, n.5, pp.408-411. ISSN 1698-6946.

Objectives: The objective was to analyze the impact of preventive programmes on oral quality of life in school students aged 11-12 yrs. Study design: In the school year 1996/97, a quasi-experimental study was initiated in Granada province with four groups of students aged 6-7 yrs: Sealant + Fluoride (sealants on first permanent molars applied in the health centre for a 3-yr active programme, and fluoride varnish applied every four months for 3 yrs, n=65), Sealant (only sealants, n=80), Fluoride (only fluoride varnish, n=107) and Control group (n=59). All students were examined every 6 months at school during the 3-yr active programme and received an oral health report after each examination. At 5.5 yrs (school year 2002/03), after 2.5 yrs with no programme, students were again examined and completed a questionnaire on oral quality of life scored from -6 (minimum) to +6 (maximum). Results: Oral quality of life values (± standard deviation) were: 3.31±0.30 (Sealant + Fluoride), 3.11±0.27 (Sealant), 3.18±0.23 (Fluoride) and 2.95±0.32 (Control), with no statistically significant differences among them. Conclusions: Fissure sealant and fluoride varnish programmes had no significant influence on oral quality of life after a 5.5- yr follow-up (3 yrs of active programme plus 2.5 yrs of discontinuation).

Keywords : Student programmes; fissure sealant; fluoride varnish; oral quality of life.
