Abstract

Amaç:
Bu çalışmanın amacı, profilaktik pat ve beyazlatma uygulamalarının ardından
farklı tip kompozitlerin mikrosertliklerini değerlendirmektir.

Gereç ve Yöntem: Şeffaf bant ile kapatılmış cam kalıplarda, nanohibrid (GrandioSO) (Grup A), nanodolduruculu akışkan (Filtek
Supreme XT Flow) (Grup B) ve nanodolduruculu kompozit (Filtek Ultimate) (Grup C) ile toplam 120 örnek (her bir
restoratif materyal için 40 örnek) hazırlanmıştır. Polimerizasyonun ardından
tüm örneklere Sof-Lex Disk Sistemi ile bitirme ve polisaj işlemleri uygulanmış
ve her bir restoratif materyalin örnekleri 4 gruba ayrılmıştır. Grup 1: 37°C distile suda iki hafta bekletilmiştir (kontrol), Grup 2:
Proxyt Fine profilaktik pat uygulanmıştır, Grup 3: Pola Office (SDI + beyazlatma yapılmıştır, Grup 4: Proxyt Fine
profilaktik pat uygulaması + Pola Office+
beyazlatma yapılmıştır (toplam 12 grup). Mikrosertlik ölçümleri dijital bir
mikrosertlik test cihazı ile gerçekleştirilmiştir (HMV-2, SHIMADZU,
Kyoto, Japonya)  (yük 500 g; bekleme süresi 15 saniye). Veriler
tek yönlü ANOVA test ile analiz edilmiştir. Çoklu karşılaştırmalar Tukey test
ile gerçekleştirilmiştir (p<0.05).

Bulgular: GrandioSO materyali için (A), Grup A4, Grup A1’den istatistiksel olarak
anlamlı derecede daha düşük mikrosertlik değerleri göstermiştir (p<0.001)
ancak Grup A1, A2 ve A3 arasında fark yoktur (p=0.51).  Filtek Supreme XT Flow (B) için 4 grup
arasında istatistiksel olarak fark yoktur (p=0.24). Filtek Ultimate materyali
için (C), Grup C1 ve C2, Grup C3 ve C4’ten istatistiksel olarak anlamlı
derecede daha yüksek mikrosertlik değerleri göstermiştir (p<0.01). Tüm gruplar için, Filtek Supreme XT
Flow (B) GrandioSO (A) ve Filtek Ultimate (C) gruplarından anlamlı derecede
daha düşük mikrosertlik değerleri göstermiştir (p<0.01).

Sonuç: Profilaktik
pat ve beyazlatmanın birlikte uygulanması ya da tek başına beyazlatma işlemi
kompozitlerin mikrosertliğini materyalin türüne bağlı olarak olumsuz
etkileyebilir.

The Influence of Prophylactic Paste
and Bleaching on the Microhardness of Different Composite Resins

Abstract

Objective: The aim of this study was to evaluate the
microhardness of different types of composites after application of
prophylactic paste and bleaching.

Materials and Methods: A total of 120
specimens (40 specimens for each restorative materials) were fabricated using a
nanohybrid (GrandioSO) (Group A), a nanofill flowable (Filtek Supreme XT
Flow) (Group B) and a nanofill composite resin (Filtek Ultimate) (Group C) in a
plexiglass mold covered with a Mylar strip. After polymerization, all specimens
were finished and polished with Sof-Lex (3M ESPE) Polishing disc  system and each restorative material specimens
were divided into four treatment groups: Group 1: stored in distilled water at 37°C for two
weeks (control), Group 2: Application
of Proxyt Fine  Prophylactic paste,
Group 3: Bleaching with Pola Office + and Group 4: Application of Proxyt Fine
Prophylactic paste + bleaching with Pola Office+ (totally 12 groups). The
microhardness measurements were performed using a digital microhardness tester (HMV-2, SHIMADZU,
Kyoto, Japan)  (load 500 g; dwell time 15 seconds). The data
were analyzed using the one-way ANOVA test. Multiple comparison was performed
with the Tukey HSD test (p<0.05).

Results: For GrandioSO
(A), Group A4 exhibited statistically significant lower microhardness values
than Group A1 (p<0.001) but there were no difference among Groups A1, A2 and
A3 (p=0.51).  In Filtek Supreme XT Flow
(B) there were no statistically significant difference for all 4 groups (p=0.24).
In terms of Filtek Ultimate (C), Group C1 and C2 showed statistically
significant higher microhardness values than Group C3 and C4 (p<0.01). For
all main groups, Filtek Supreme XT Flow (B) exhibited statistically significant
lower microhardness values than 
GrandioSO (A) and Filtek Ultimate(C) (p<0.01).

Conclusion: Application of
Prophylactic Paste and bleaching procedure together or bleaching procedure
alone may negatively affect the microhardness of composites depending on the
type.
