RESUMO
Introduction: Cancer is considered a major public health problem worldwide and may have an important impact on oral health-related quality of life (OHRQoL). Thus, the present study aimed to assess OHRQoL in Brazilian patients aged 3 to 21 years undergoing cancer treatment. Materials and Methods: In total, 121 patients receiving cancer treatment and 363 healthy individuals (control group) were evaluated. OHRQoL was assessed using an age-specific questionnaire, that is, the Brazilian versions of the Early Childhood Oral Health Impact Scale (ECOHIS), the Child Perceptions Questionnaire (CPQ) 11-14-short version, the CPQ 8-10-short version, and the short-form of Oral Health Impact Profile Questionnaire-14 (OHIP-14). Results: Individuals from the control group who were evaluated by the ECOHIS presented more impact on the OHRQoL regarding the psychological and family function score, as well as those evaluated by CPQ 8-10, who presented more impact in general. However, considering CPQ 11-14, cancer patients had their OHRQoL more affected, as shown in both the total questionnaire score and oral symptoms score. Conclusion: Within the limitations of this Brazilian study, cancer treatment seems to be associated with decreased OHRQoL only in patients aged between 11 and 14 years. However, children without cancer aged between 8 and 10 years seem to experience worse OHRQoL.
