Abstract
Objective: This paper report oral health education actions carried out in an institution supporting children and adolescents with cancer in a municipality of the Brazilian Amazon. Experience Report: A descriptive study of the experience report type that consisted of the use of active methodology (Marguerez Arc Problematization Methodology). The activities favored playful strategies, valuing the participants' experience, aiming at the incorporation of healthy habits in the face of critical health and oral morbidity situations. In spite of the individual difficulties in coping with cancer, important behavioral changes for the adoption of adequate self-care practices were developed in order to understand the meaning of this care in the general health context and to incorporate them into their routine. Final considerations: Health education practices for high vulnerability groups should value strategies that involve effective participation. Under these conditions, the encouragement of self-care and the understanding of the cause and effect relationship involving the determinants of morbidity are relevant. Accomplishing all this in a pleasant atmosphere allows for the involvement and understanding that preventing comorbidities is competing for health promotion, even under unsatisfactory general conditions.
