Abstract

Amaç: Bu
çalışmanın amacı, farklı dezenfeksiyon yöntemlerinin (%2 glutaraldehit, %5 sodyum
hipoklorit ve mikrodalga) yeni üretilen prefabrike olarak polimerize edilmiş
CAD/CAM akrilik rezin, ısı ile ve kimyasal polimerize olan akrilik
rezinlerin yüzey sertliği üzerindeki etkisini değerlendirmektir.

Gereç ve
yöntem:  15 mm çapında 2 mm
kalınlığında disk şeklinde hazırlanan örnekler kontrol ve 3 farklı test grubuna
ayrılmıştır (n = 8): Grup 1: kontrol, 37°C'de distile su içinde; Grup 2: %2’lik
glutaraldehit; Grup 3: %5’lik sodyum hipoklorit; Grup 4: mikrodalga
dezenfeksiyonu (650 W / 6 dak). G2 ve G3 örnekleri bir saat boyunca dezenfektan
solüsyonda bekletilmiştir. Yüzey sertliği ölçümleri (Vickers Sertliği), 2 yönlü
ANOVA ve Tukey’s Honestly Significant Difference testi (α=.05) kullanılarak
analiz edilmiştir.

Bulgular:
Tüm gruplarda en yüksek yüzey sertlik değerleri kontrol gruplarında bulunmuştur.
Prefabrike olarak polimerize edilmiş CAD/CAM akrilik rezinler bütün
gruplarda en yüksek yüzey sertliği göstermiştir (p<0,001). %5’lik sodyum
hipoklorit dezenfeksiyonu, ısı ile ve kimyasal polimerize olan akrilik
rezinlerin yüzey sertliği üzerinde etkili olmuştur (p <0,001).

Sonuçlar:
Bu çalışmanın sınırları dahilinde, yeni üretilen prefabrike olarak
polimerize edilmiş CAD/CAM akrilik rezinlerin yüzey sertliği, dezenfektan
yöntemlerinden bağımsız olarak dezenfeksiyondan etkilenmemiştir.

Effect of
Various Disinfection Methods on the Surface Hardness of CAD/CAM and
Conventional Acrylic Resins

ABSTRACT

Objectives: The aim of the
current study was to assess
the effect of simulated disinfections (2% glutaraldehyde, 5% sodium
hypochlorite, and microwave) on the surface hardness of newly introduced
pre-polymerized acrylic resin, heat and self cured acrylic resin.

Materials and Methods: Disc
shaped specimens, 15 mm diameter
and 2 mm thickness, were divided into a control and 3 test groups (n=8): Group 1:
control, stored in distilled water at 37°C; Group 2: 2% glutaraldehyde; Group 3:
5% sodium hypochlorite;  Group 4:
microwave disinfection (650 W/6 min). G1 to G3 were immersed for an hour in the
disinfectant solution. Measurements of surface hardness (Vickers Hardness) were
analyzed using 2-way ANOVA and Tukey’s Honestly Significant Difference (HSD)
test (α=.05).

Results:
The control groups showed the highest surface hardness values in all groups.
Pre-polymerized block acrylic resin showed the highest surface hardness in all
of the groups (p<0,001). The 5% sodium hypochlorite disinfection had an
effect on the surface hardness of heat and self cured acrylic resins
(p<0,001).

Conclusions:
Within the limitation of the current study, surface hardness of newly
introduced pre-polymerized acrylic resin was not affected by disinfection
regardless of the disinfectant methods.
