Background: Patients undergoing head-and-neck radiotherapy are susceptible to colonization and infection. This study aimed to identify oral species type (ST), colony count (CC), and oropharyngeal candidiasis (OPC) in head-and-neck cancer patients, undergoing radiotherapy, before and 2 weeks after radiation.
Materials And Methods: In this quasi-experimental study, head-and-neck cancer patients undergoing radiotherapy (up to 6000 cGy) were recruited.
