DEZENFEKTAN KULLANIMININ ELASTOMERİK ÖLÇÜ MATERYALLERİNİN BOYUTSAL STABİLİTESİ ÜZERİNE ETKİSİNİN İN VİTRO OLARAK İNCELENMESİ

Amaç: Bu çalışmanın amacı iki farklı sprey dezenfektan kullanımının elastomerik ölçü maddelerinin boyutsal stabilitesi üzerine etkisinin in vitro olarak incelenmesidir. Gereç ve Yöntem: Çalışmamızda 3 farklı ölçü mad- desi (polieter, kondensasyon tip silikon ve ilave tip silikon) ve iki farklı sprey dezenfektan (Zeta 7: isop- ropanol esaslı ve Descosept: kuarterner amonyum bileşikleri esaslı) kullanıldı. Ölçülerin alınması için pas- lanmaz çelik model kullanıldı ve her bir ölçü madde- sinden 30 adet olacak şekilde, toplam 90 adet ölçü elde edildi. Her bir ölçü maddesi için 10’ar örnek içeren 3 grup oluşturuldu. Zeta 7 ve Descosept sprey uygulanan gruplar 15 dakika bekletildi ve akan su altında yıkandı. Diğer grup ise kontrol grubu olarak kullanıldı. Ölçülere sert alçı dökülerek modeller elde edildi. Hazırlanan alçı modeller üç boyutlu bir dental tarama cihazında taranarak dijital görüntüleri oluşturuldu. Elde edilen dijital model görüntüleri üzerinde cihazın kendi yazılımı kullanılarak referans noktaları arasında lineer ölçümler yapıldı. Bulgular: Elde edilen verilerin istatistiksel analizi SPSS 22.0 programı kullanılarak yapılmıştır. Verilerin normal dağılıma uyup uymadığı Shapiro-Wilk testi ile kontrol edil- miş ve verilerin normal dağılıma uyması nedeniyle para- metrik test kullanılmıştır. İki farklı dezenfektan materya- linin, farklı ölçü materyalleri üzerindeki boyutsal stabilite- sine olan etkisinin değerlendirilmesi için independent t testi kullanılmıştır. Sonuçlar %95’lik güven aralığında değerlendirilmiştir. Sonuç: Kondanse silikon grubunda her iki kimyasal dezenfektan ajanında boyutsal değişim açısından ista- tistiksel olarak anlamlı fark gözlemlenmiştir (p<0,05). Polieter ve ilave tip silikon gruplarında her iki kimyasal dezenfektan ajanı uygulaması sonucu boyutsal stabilite açısından istatistiksel olarak anlamlı fark gözlemlen- memiştir (p<0,05).

Material and Methods: In our study, we used 3 different impression materials (polyether, condensation type silicone and additional type silicone) and two different spray disinfectants (Zeta 7: based on isopropanol and Descosept: based on quaternary ammonium compounds). A stainless steel model was used for taking measurements and at each to be 30, a total of 90 measurements was obtained. For each impression materials, 3 groups of 10 samples were formed. Zeta 7 and Descosept sprayed groups were left for 15 minutes and washed under running water. The other group was used as the control group. Molds were filled with hard gypsum plaster. Dimensional stability were evaluated using a three-dimensional dental scanning device. Linear measurements were made between the reference points on the digital model images using the device's own software. Results: Statistical analysis was performed using the SPSS 22.0 program. The data was controlled by the Shapiro-Wilk test and parametric test was used because of the normal distribution of the data. Independent t test was used to assess the effect of disinfection procedures on dimensional stability of elastomeric impression materials. The results were evaluated in 95% confidence interval. Conclusion: There was statistically significant difference in the mean values of dimensional stability in condensation type silicone (p<0,05). There was no statistically significant difference in the mean values of dimensional stability in polyether and additional type silicone (p<0,05). Key Words: cross infection, disinfectant, disinfection of impression
