The aim of this study is to identify potential facilitators and barriers to dental care in head-neck cancer patients from the perspective of affected patients, dentists, and oncologists (specialists in radiotherapy and specialists in otolaryngology).

Patients as well as dentists and oncologists will be interviewed in semi-structured individual interviews. The interview guide used will align with the 14 domains of the Theoretical Domains Framework. Through qualitative content analysis, both facilitators and barriers to dental treatment for head-neck cancer patients will be identified.

• Dentists practicing in Germany
• Specialists in otorhinolaryngology practicing in Germany
• Specialists in radiation therapy practicing in Germany
