Amaç:
Bu in-vitro çalışmanın amacı; uzatılmış saklama sürelerinin, uzatılmış model
elde etme süresine sahip irreversible hidrokolloid ölçü malzemelerinin yırtılma
dayanımı üzerine etkisini incelemektir.



Materyal-Metod:  Beş
ticari 
(BluePrint
Xcreme, Hydrogum 5,  Kromopan, Alginmax
ve Alginelle) ve bir özel formüle
edilmiş  uzatılmış model etme süresine
sahip irreversible hidrokolloid ölçü malzemesi kullanılarak ISO 21563:2013
standartlarına uyumlu seksen dört adet numune hazırlanmıştır.  Her bir ölçü malzemesine sait numuneler  rastgele iki gruba ayrılmış (n=7) ve  hemen 
veya 120 saatlik saklama süresi sonunda yırtılma testine tabi
tutulmuşlardır. Yırtılma dayanımı değerleri N/mm cinsinden ifade edilmiş ve
veriler  iki yönlü varyans analizi testi
(irreversible hidrokolloid markası, saklama süresi) kullanılarak analiz
edilmiştir. Çoklu karşılaştırmalara, Tukey testi kullanılarak yapılmıştır (p=0.05).



Bulgular:
 
Uzatılmış model etme süresine sahip irreversible
hidrokolloid ölçü malzemelerinin yırtılma dayanımları, irreversible
hidrokolloid markası parametresi
(p<0.0001)  ve irreversible
hidrokolloid markası-saklama süresi etkileşimi tarafından etkilenmiştir (p=0.005).
   tarafından etkilenmiştir  Saklama süresi, uzatılmış model etme süresine
sahip irreversible hidrokolloid ölçü malzemelerinin yırtılma dayanımlarını, 120
saat saklama süresi sonunda yırtılma dayanımı artan   Alginmax  ölçü malzemesi haricinde etkilememiştir (p<0.05).  Hemen yapılan yırtılma dayanımı testinde Blueprint
Xcreme en yüksek ortalama yırtılma dayanımı değerlerine sahipken  (1.08±0.19 N/mm) Alginelle  en düşük 
ortalama yırtılma dayanımı değerlerini göstermiştir (0.51±0.3 N/mm). 120
saat saklama süresi sonunda Hydrogum 5 en yüksek ortalama yırtılma dayanımı
değerlerine sahipken (1.15± 0.12 N/mm) Alginelle en düşük  ortalama yırtılma dayanımı değerlerini
göstermiştir (0.55±0.04 N/mm).



Sonuç: Test edilen   uzatılmış
model elde etme süresine sahip  ticari irreversible
hidrokolloid ölçü malzemelerinin tümü,
yırtılma dayanımlarını 120 saatlik saklama süresi sonunda korumuştur.

Effect of storage time on tear strength of extended-pour irreversible hydrocolloid impression materials

Objective:
The aim of this in vitro study was to evaluate the effect of prolonged storage
times on the tear strength of extended-pour irreversible hydrocolloid
impression materials.

Material and Method: Eighty four specimens were fabricated from  five commercial extended-pour irreversible
hydrocolloid impression materials (BluePrint Xcreme, Hydrogum 5,  Kromopan, Alginmax and Alginelle)  as well as one experimental formula in
accordance with the ISO 21563:2013 standard  
effective for irreversible hydrocolloid impression materials. Specimens
were randomly divided in two groups for each impression material (n=7) and
subjected to tear strength test immediately (base line) or after 120 hours of
storage.  Tear strength values were obtained
in N/mm and data were   analysed with
two-way ANOVA (irreversible hydrocolloid brand, storage time). Multiple
comparisons were performed with Tukey’s test (p=0.05).

Results:
The tear strength of the extended-pour
irreversible hydrocolloid impression materials were affected by brand (p<0.0001)
and brand-storage time interaction (p=0.005). Storage time did not influence
the tear strengths of the extended-pour irreversible hydrocolloid impression
materials tested except Alginmax whose mean tear strengths increased after 120
hours of storage (p<0.05).  At base
line measurements Blueprint Xcreme provided the highest mean tear strength
values (1.08±0.19 N/mm) whereas Alginelle provided  the lowest mean tear strength values
(0.51±0.3 N/mm). Hydrogum 5 provided the highest tear strength values after 120
hours of storage  (1.15± 0.12 N/mm)
whereas Alginelle provided  the lowest
mean tear strength values (0.55±0.04 N/mm).







Conclusion.
All commercial
extended-pour irreversible hydrocolloid impression materials tested maintained
their tear strengths after 120 hours of storage.
