Long-term effect of an educational intervention regarding dental trauma first aid: a phase II study

Interventions that improve knowledge about emergency management of traumatic dental injuries may be a good way to achieve a more favorable prognosis in such situations. We set out to evaluate the short- and long-term effects of combined educational interventions on health teachers, including lecture presentation, question-and-answer sessions, and informational posters to promote awareness regarding emergency measures for traumatized teeth. Assessment was performed using a three-part questionnaire, including demographic data, knowledge, and self-assessment. Using a census sampling method, 52 health teachers of 68 potential candidates participated in the study. The questionnaires of 38 teachers who participated at all three intervals, including before (T0), immediately after (T1), and 36 months after (T2) the intervention, were analyzed. Statistical analysis involved Cochrane and McNemar's tests. Totally, results revealed an increase in knowledge from T0 to T1 and T2 intervals (P < 0.017). This study shows the positive effect of educational campaigns and, therefore, serves to encourage professionals to embark on innovative educational programs in this field.
