Self-assessed bleeding and plaque as methods for improving gingival health in adolescents.
The aim of this longitudinal study was to compare the effectiveness, in terms of cognitive and clinical changes, of two oral self-care promoting interventions based on a self-assessment of bleeding from gums or of presence of plaque. Adolescent students (age 14.0 + 0.7 years) from two health districts in Helsinki, Finland, participated in this one-year study. The self-assessment of bleeding group (n = 172) recorded bleeding during tooth brushing and inter-proximal cleaning with toothpicks on a single session. The self-assessment of plaque group (n = 156) recorded the presence of plaque with disclosing dye. Both programmes resulted in comparable clinical improvement in bleeding on probing over 9 months. Increased awareness of gingivitis was associated with clinical improvement. The subjects' socio-economic background, baseline gingival health status and age were statistically significantly associated with gingival health improvement during the follow-up. The results support earlier reports on self-assessment and suggest that both self-assessment approaches are beneficial for promoting gingival health in adolescents.
