DEZENFEKSİYONUN MAKSİLLOFASİYAL SİLİKON ELASTOMERİN FİZİKSEL ÖZELLİKLERİ ÜZERİNE ETKİLERİ

Amaç: Bu çalışmanın amacı farklı dezenfeksiyon işlemlerinin maksillofasiyal silikon elastomerin yüzey pürüzlülüğü ve renk stabilitesi üzerine etkisinin değerlendirilmesidir.Gereç ve Yöntem: Maksillofasiyal silikon (M511; Technovent) materyalinden 60 adet disk şeklinde (15 mm çapında 3 mm kalınlığında) örnek hazırlandı. Örnekler dezenfeksiyon işlemlerine göre; 1) kontrol (distile su), 2) efervesan tablet (Corega), 3) nötral sabun (Sebamed), 4) dermal dezenfektan (Biorad Derm), 5) klorheksidin glukonat (Andorex) ve 6) otoklav olmak üzere altı gruba ayrıldı (n=10). Dezenfeksiyon işlemi otoklav grubu hariç günde iki defa 15 gün boyunca uygulandı. otoklav grubunda ise dezenfeksiyon toplamda 3 defa yapıldı. Renk ölçümleri, dezenfeksiyon işlemi öncesi ve sonrasında spektrofotometre ile gerçekleştirildi. Renk parametreleri kaydedilerek ΔE00 değerleri hesaplandı. Yüzey pürüzlülüğü (Ra) ölçümleri ise dezenfeksiyon işlemi öncesi ve sonrasında profilometre cihazı ile gerçekleştirildi. Elde edilen veriler; tek yönlü ANOVA ve tekrarlayan ölçümler için ANOVA testleri kullanılarak istatistik olarak analiz edildi (α=0,05).Bulgular: Otoklav grubunda ΔE00 değerleri (3,79); diğer gruplardan anlamlı derecede daha yüksek bulunurken diğer gruplar arasında istatistik olarak anlamlı fark yoktur (0,92-1,37) (P>0,05). Dezenfeksiyon işlemi öncesi ve sonrasında yüzey pürüzlülüğü değerlendirildiğinde dezenfeksiyon sonrası kontrol, efervesan tablet, nötral sabun, ve dermal dezenfektan gruplarında yüzey pürüzlülüğü değerleri anlamlı derecede daha yüksek bulundu (P<0,05). Nötral sabun grubunun dezenfeksiyon sonrası yüzey pürüzlülüğü değeri klorheksidin glukonat ve otoklav gruplarından anlamlı derecede daha yüksek bulundu (P<0,05).Sonuç: Otoklavda yapılan dezenfeksiyon işleminin maksillofasiyal silikon elastomerin renk değişimi üzerinde önemli etkisi bulunmaktadır. Dezenfeksiyon işlemleri genellikle maksillofasiyal silikon elastomerin yüzey pürüzlülüğünü arttırmaktadır.Anahtar kelimeler: dezenfeksiyon, maksillofasiyal protez, renk, silikon elastomerler Effects of Disinfection on the Physical Properties of a Maxillofacial Silicone Elastomer Abstract Aim: The purpose of this study was to evaluate the effects of different disinfection procedures on the surface roughness and color stability of the maxillofacial silicone. Material and Methods: Sixty disc-shaped specimens (15 mm in diameter and 3 mm in thickness) were fabricated from a maxillofacial silicone rubber (M511; Technovent). The specimens were divided into six groups according to the disinfection procedures: 1) control (distilled water), 2) effervescent tablets (Corega), 3) neutral soap (Sebamed), 4) dermal disinfectant (Biorad Derm), 5) chlorhexidine gluconate (Andorex), and 6) autoclave (n=10). Disinfection was performed two times a day for 15 days except group autoclave. In the group autoclave disinfection was applied for three times in total. Color measurements were performed by using a spectrophotometer before and after disinfection process. Color parameters were recorded and ΔE00 values were calculated. Surface roughness (Ra) were measured before and after disinfection process, using a contact stylus profilometer. Data were statistically analyzed using one-way and repeated measures of ANOVA tests (a=0.05). Results: Group autoclave showed the significantly higher ΔE00 values (3.79) among the groups, while the ΔE00 values of the other groups (0.92-1.37) were not statistically significant (p>0.05). When surface roughness were evaluated, the Ra values were significantly higher in control, effervescent tablets, neutral soap, and dermal disinfectant groups after the disinfection methods (p<0.05). The Ra values of group neutral soap after the disinfection were found significantly higher than chlorhexidine and autoclave groups (p<0.05). Conclusion: Autoclave disinfection had the higher impact on the color change of maxillofacial silicone. Disinfection procedures generally increased surface roughness.
