The effectiveness of an oral health education and prevention program on the incidence and severity of oral mucositis in pediatric cancer patients: a non-randomized controlled study.

PURPOSE: To investigate the effectiveness of an Oral Health Education and Prevention Program (OHEPP) on the incidence and severity of oral mucositis (OM) in pediatric cancer patients. The OHEEP was a ludic strategy for promoting oral health and monitoring the oral health condition. METHODS: We compared the incidence and severity of OM in patients who attended the OHEPP against those under similar conditions who did not receive educational interventions. Both groups were examined for 6 weeks by calibrated examiners (k > 0.8) using the modified Oral Assessment Guide (OAG). A total of 14 patients aged 2 to 18 years were included in each group and matched for sex, age, tumor type, and treatment modality. The incidence and severity of OM were compared using the chi-squared test (α = 5%), and the relative risk and effectiveness of the OHEPP were calculated with a statistical power of 0.97. Differences in total OAG scores between the groups were determined by the Mann-Whitney test (α = 5%). RESULTS: There was a higher incidence of OM in patients who did not attend the OHEPP (P = 0.005), and the relative risk of developing OM was significantly lower in OHEPP attendants (RR: 0.73; CI 0.60-0.92). No difference in the occurrence of severe OM was observed. OHEPP reduced the risk of developing OM by 1.4-fold, with an effectiveness of 27%. There was a difference in total OAG scores (P = 0.041). CONCLUSION: Participation in OHEPP was an effective measure to reduce the incidence of OM in pediatric cancer patients.
