Investigation of Radiation Effects on Cr-Co-Ni Alloys Used in Dental Applications by Monte Carlo Simulation

İngilizce (OpenAlex)

Radiation is used in dental applications, both in any tumor treatment and oral diagnosis. Especially boron -neutron treatment mostly uses brain and larynx cancer treatment. In recent years, denture restoration has become important in combating tooth decay and tooth loss. Many alloys are used for both restoration and medical purposes, with cobalt-chromium (Co-Cr) alloys seeing increasing use. These alloys are favored because they offer good resistance to corrosion and mechanical wear. Toxicity and radiation resistance are crucial properties of these alloys in oral applications. Individuals with chrome-coated implants and restorations may be exposed to radiation during diagnostic procedures while working in nuclear facilities or undergoing radiotherapy treatments like boron neutron therapy. The epithermal and fast neutron interaction parameters, including effective removal cross-section, half-value layer, mean free path, and transmission number, have been determined for dentures used in medical applications with three types of Co-Cr alloys. These parameters and the emitted secondary radiation were calculated using the effective semi-experimental Monte Carlo simulation software, GEANT4. It was determined that the first type of alloys are best suited for oral restorations in people exposed to radiation.
