The purpose of this study was to clarify the effectiveness of personal instruction for students with gingivitis under observation (GO) from a Yogo teacher at a special needs school. The subjects were 6 students of the 7th to 9th grade at a special needs school in Gunma Prefecture, Japan whose social ages were 6.0 to 7.1 years. To provide a sense of achievement to such subjects, the Yogo teacher placed an emphasis on performing activities with subjects and making positive comments about the results achieved. The instructional program at the school was composed of 2-day instructional blocks given once per week over a period of 3 weeks. The gingival conditions and the living activities of the subjects, such as clean and healthy activities, and tooth brushing activities, produced improvement in all subjects after the instructional program. PMA indices became significantly lower for all subjects. The number of items related to tooth brushing increased for all subjects. Parent awareness of brushing as a step toward self-reliant behavior also increased. These results show that the personal instruction for students with GO from the Yogo teacher at a special needs school was effective in students with social age of 6.0 years and more.
