Amaç: Bu çalışmanın amacı; protez temizleyici solüsyonların ısı ile polimerize olan akrilik rezinin mikrosertliği üzerine etkisini incelemektir.

Gereç ve Yöntem: 50 akrilik rezin
örnek (15 mm × 15 mm × 3 mm) hazırlandı. Örnekler rastgele dağıtılarak,
sıralanan solüsyonlara göre gruplara ayrıldı: 
% 0.2 klorheksidin glukonat, %0.5 sodyum hipoklorit (NaOCl), %1 NaOCl,
alkalin peroksit tablet solüsyonu (n=10). Kontrol grubu örnekler distile suda
bekletildi. Solüsyonlarda bir daldırma 20-dakika olarak belirlendi. Her bir
örneğin Vickers sertlik değeri mikrosertlik cihazı ile daldırma öncesi ve 720
daldırma sonrası ölçülerek karşılaştırıldı. 
Veriler SPSS 15.0 programına taşınarak eşleştirilmiş örneklemler t-testi,
tek yönlü varyans analizi ve Tukey HSD testi ile gruplar arası karşılaştırmalar
yapıldı (p< 0.05).

Bulgular: Bulgular alkalin peroksit tablet solüsyonunun akrilik rezinin mikrosertliğinde istatistiksel olarak anlamlı azalmaya yol açtığını göstermiştir. Çalışmada test edilen diğer solüsyonlar akrilik rezinin mikrosertliği üzerinde anlamlı bir etkiye neden olmamıştır.

Sonuç: Alkalin peroksit tablet solüsyonu hariç distile su, %0.2 klorheksidin glukonat, % 0.5 NaOCl ve %1 NaOCl solüsyonları günde 20 dakika kullanımı taklit eden 720 kullanım periyodunda ısı ile polimerize olan akrilik rezinin mikrosertliğini anlamlı olarak etkilememiştir

 EFFECT OF DENTURE CLEANSING SOLUTIONS ON MICROHARDNESS OF A HEAT-CURE ACRYLIC RESIN
Aim:The aim of this study was to investigate the influence of denture cleansing solutions on micro hardness of a heat-cure acrylic resin.

Materials and Methods: Fifty specimens (15
mm × 15 mm × 3 mm) were prepared with a heat-cure acrylic resin. Specimens were
randomly distributed into groups and immersed in the following solutions: 0.5%
sodium hypochlorite (NaOCl), 1% NaOCl, alkaline peroxide tablet solution and,
0.2% chlorhexidine gluconate. The control group was immersed in distilled
water. An immersion was detected 20-minute for all solutions. The microhardness
value of each specimen was obtained using the microhardness testing machine
recording the Vickers hardness number before the beginning of the immersion
cycles and after completion of 720 immersion cycles and compared. Data were
imported to SPSS 15.0 software and were analyzed by paired t-test and One-Way
ANOVA and Tukey HSD test were used for comparison among groups (p< 0.05).

Results: The results show that alkaline peroxide tablet solution caused the statistically significant reduction of the microhardness of the acrylic resin. Other solutions tested in this study did not cause a significant effect on the microhardness of the acrylic resin.

Conclusions:It was concluded that immersion in distilled water, chlorhexidine gluconate, 0.5% NaOCl and, 1% NaOCl solutions, simulating 720 days of 20 min daily soaking did not cause clinically significant adverse effects on the microhardness of the heat-polymerized acrylic resin, except for the alkaline peroxide tablet solutions.
