What do the radiation oncologist, oral surgeon say? Is it erupted? Will it be in the radiation field? Radiation Dosage? Impacted?
They say if the 3rd molar is erupted, and in the radiation field, it should be extracted before radiation, as well as any other teeth that are in disrepair and unrestorable.
The below older study mentions preirridation extractions, and ORN.
Impacted 3rd molar teeth extracted have risk of ORN. I'm dealing with that now.
Less than 50Gy is less likely to have ORN, but with chemo it increases the risk.
Any extractions should be done 21 days, minimum 14 days before starting radiation to prevent ORN later on, even with chemo to prevent infections.
