Background: There is a range of pre-radiation therapy (RT) dental care strategies used to prevent the side effects associated with the use of RT in the treatment of head and neck cancer. However, there is a paucity of evidence-based, prospectively tested clinical practice guidelines for dentists to utilize in the provision of care prior to RT.
Purpose: The aim of this study is to describe the process of creating consensus guidelines for dental care in head and neck cancer patients undergoing RT using the Modified Delphi Technique.
Procedure: We invited 44 dental oncologists to participate as panelists in the study. Three rounds of iterative structured surveys were completed within eight months, followed by a virtual meeting to conclude the modified Delphi process. Questions were divided into six main domains and patients were categorized as low, moderate, and high-risk based on factors identified by panelists and agreed upon during the first round. The threshold value set for each round of the Delphi process was a 70% response rate and 75% Consensus level.
Findings: Eighteen panelists out of the forty-four (41% overall response rate) completed the study. The number of questions that achieved the set consensus level in rounds 1,2,3 and the virtual meeting were 24%, 62%,61% and 81%, respectively. A confidence level of 95% and a response rate of >75% were reached throughout the process.
Conclusion: Consensus was attained in most of the questions in all domains, which will be utilized to develop guidelines for dental care in head and neck cancer patients before the commencement of RT.
