I don't think there's 100% chance that if ionizing radiation hits a chromosome that it develops cancer. Only certain genes on your chromosome, if mutated, will cause cancer. A protooncogene needs to be mutated in some manner to become an oncogene, but not all genes are protooncogenes. Only those genes which could, upon mutation, cause the cell to gain some sort of advantage (IE: longer/more stable life, or abnormal groth factor secretion) are likely to lead to cancer. Furthermore, if the radiation damage is significant, the cell will often go through aptopsis (programed cell death), if the cell itself determines that it is too damaged to go through mitosis. A mutation in a mechanism that confers aptopsis and thus does not let a cell kill itself can cause a tumor.

I read a new study saying how dangerous dental xrays are, seeping into the brain, can anyone speculate?

They're fine.
