Maintaining adequate oral care and managing oral mucositis can be challenging. Parents are required to support their child during cancer treatment but often lack confidence and knowledge. The present study aims to determine whether parents received information on oral hygiene instructions during their child\u2019s cancer treatment and to assess the provision of oral care before, and after cancer diagnosis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A cross-sectional observational study was performed.

During cancer treatment, 60% of children from IPO-Porto and 49% from CHUSJ brushed their teeth twice a day.
