| Research Abstract |
It is important that distribution of radiation doses surrounding dental implants were clarified in radiotherapy. Dose simulation in radiotherapy to tongue was performed using Monte Carlo technique. Also, doses surrounding dental implants were measured using^<137> Cs radiation source and thermoluminescence dosimeter(TLD).
In dose simulation, absorbed doses with dental implants in source side were larger in comparison with those without dental implants. Maximum increase of absorbed dose with dental implants was approximately 40% in 6MV-X-ray and 20% in 0.412MeV-ganma ray, respectively.
In measurement using TLD, absorbed dose with dental implants decreased 47.9% in buccal side.
