    Head and neck cancer has a global burden of approximately 880,000 new cases annually, with radiotherapy used in about 75% of treatments.

  • 2

    Osteoradionecrosis (ORN) occurs in 7-10% of patients and is characterized by severe complications affecting quality of life.

  • 3

    The NTCP model developed by van Dijk et al. identified D30% and pre-RT dental extraction as key predictors of ORN.

  • 4

    The WAFT model introduced a time-to-event framework, showing that each additional Gray of radiation shortens the time to ORN onset.

  • 5

    Methodological limitations in existing NTCP models include insufficient cohort diversity and inadequate characterization of RT protocols.
