Abstract

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.
