It seems understanding who is more susceptible is quite a mystery. Radiation is the most likely cause as radiated bone is weakened and since each of our radiation treatments are completely mapped to our unique case, it is very hard to put into categories. Also, radiation bounces off metal fillings and such and that further complicates the ability to determine where to be watchful of developing ORN.

Logic would suggest those who had cancer in the gum, jaw, or very near these areas would be more at risk for ORN but I've not come across any studies to shed more light on it.

Most don't suffer ORN and it starts over a long timeframe, just adding to the mystery.

Then you have such a difference in opinions on what is the proper protocols for watching and treating it.

Thank goodness for OCF to create a place where it can be discussed as without this it would be virtually impossible to have any idea what to expect or have practical experiences to guide one suffering it.
