Abstract:

 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.

 Radyasyon diş hekimliği uygulamalarında hem her türlü tümör tedavisinde hem de ağız yoluyla teşhiste kullanılmaktadır. Özellikle bor-nötron tedavisinde çoğunlukla beyin ve gırtlak kanseri tedavisinde kullanılmaktadır. Son yıllarda diş çürüğü ve diş kaybıyla mücadelede protez restorasyonu önem kazanmıştır. Birçok alaşım hem restorasyon hem de tıbbi amaçlar için kullanılmakta özellikle kobalt-krom Co-Cr alaşımlarının kullanımı giderek artıyor. Bu alaşımlar, korozyona ve mekanik aşınmaya karşı iyi bir direnç sundukları için tercih ediliyor. Toksite ve radyasyon direnci bunların çok önemli özellikleridir. Oral uygulamalarda alaşımlar krom kaplı implantlara ve restorasyonlara sahip kişiler, nükleer tesislerde çalışırken veya bor nötron tedavisi gibi radyoterapi tedavilerine tabi tutulurken teşhis prosedürleri sırasında radyasyona maruz kalabilirler. Üç tip Co-Cr alaşımı ile tıbbi uygulamalarda kullanılan protezler için epitermal ve hızlı nötron etkileşimi parametreleri etkili uzaklaştırma kesiti, yarı değer katmanı, ortalama serbest yol ve iletim sayısı belirlendi. Bu parametreler ve yayılan ikincil radyasyon, etkili yarı deneysel Monte Carlo simülasyonu kullanılarak hesaplandı. GEANT4 yazılımı ile radyasyona maruz kalan kişilerde ağız restorasyonları için birinci tip alaşımların en uygun olduğu belirlendi.
