Enrolment started in November 2017 with allocation of patients to one of the study groups by means of randomisation.

Monitoring includes daily assessment of mucositis grade and diameter measurement by photographs and millimetre periodontal probe. Treatments will be concluded once mucositis is healed. A blinded assessor will evaluate mucositis cure after referred by the study team. At this point, the gel tube will be weighed to indirectly assess patient\u2019s compliance. At close-out, data will be analysed by a blinded researcher following the procedures described in the statistical analyses.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Ethics and dissemination<\/jats:title>\n                    <jats:p>This clinical trial was approved by the ethics committee of research in humans at the Faculty of Medical Sciences of University of Campinas (report no. 1,613,563\/2016).
