METHOD FOR SIMULATING DAMAGING ACTION OF IONISING RADIATION ON SOLID TISSUES OF HUMAN TOOTH Russian patent published in 2012 - IPC A61N5/10 G09B23/28 G01T1/11 G03C3/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, dentistry, oncology and radiology, and may be used for improving the quality of dental aid to the patients suffering malignancies in head and neck after radiation therapy. Reduction of the mechanical properties of dental dentine radiated in therapeutic doses in vitro is stated in a maxillofacial phantom representing a tissue-equivalent heterogenous antropomorphic human oral phantom with cells to place extracted teeth of an individual. Tissue substitutes for creating the phantom are presented by porcine bones and mixed imitated soft tissue, weight portions: paraffin - 100, magnesium oxide (MgO) - 29.06, calcium carbonate - 0.94. The dose control is ensured by light-sensitive film and thermoluminescent dosimetry.

EFFECT: method provides evaluation of a degree of radiation damages of dental dentine, higher accuracy of dose correlation in therapeutic maxillofacial tumour radiation with changing the mechanical properties of the dentine and its strength.
