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).

IN VITRO EVALUATION OF THE EFFECT OF DISINFECTION
PROCEDURES ON DIMENSIONAL STABILITY OF ELASTOMERIC IMPRESSION MATERIALS

ABSTRACT

 

Aim: The aim of this study was to determine the effect of
spray disinfection procedures on the dimensional stability of elastomeric
impression materials.

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).
