Despite great improvement in the oral health of populations globally, problems still persist both in developed, and developing countries. One-fifth of the world’s population is adolescent. A young person with high self-esteem and good social skills who is clear about her/his values and has access to relevant information is likely to make positive decisions about health. The school system is the logical environment in which to teach preventive dental health practices. The school can provide a supportive environment and an ideal setting for promoting oral health.
