Bu çalışmanın amacı marka, bekletme solüsyonu ve
saklama süresinin irreversible hidrokolloid ölçü maddelerinin boyutsal
stabilitesi üzerine etkilerinin incelenmesidir.

Ölçüler, yapay üst çene modelinden oluşturulmuş yeni
bir cihaz yardımıyla beş farklı irreversible hidrokolloid ölçü maddesi
kullanılarak alındı. Toplamda 245 adet ölçü saklama şartları ve süreleri
dikkate alınarak kontrol grubu, iki ana grup ve üç alt gruba ayrıldı. Her bir
ölçüden alçı modeller elde edildi, beş farklı uzunluk ölçüldü ve birbiri ile
karşılaştırıldı.

İrreversible hidrokolloid ölçü maddesinin markasına
göre yapılan gruplar arası karşılaştırma istatistiksel olarak anlamlı
farklılıklar gösterdi. Saklama süresi tüm mesafe ölçümlerinde istatistiksel
olarak anlamlı etki yaratırken iken saklama koşulları bazı mesafe ölçümlerinde anlamlı etkiye
sahipti.

İrreversible hidrokolloid ölçü maddeleri bekletme
solüsyonunda veyahut kilitli plastik torbalarda iki haftaya kadar
bekletilebilir. Ölçü maddesinin tipi, saklama şartları ve saklama süresi
boyutsal stabilite üzerinde etkilidir.

STORAGE CONDITION AND PERIOD EFFECT ON THE DIMENSIONAL STABILITY OF IRREVERSIBLE HYDROCOLLOID IMPRESSION MATERIALS

Öz

The aim of this study was to evaluate the effects of
brand, holding solution and storage periods on dimensional stability of
irreversible hydrocolloid impression materials.

Impressions were taken from a master maxillary
typodont, using a newly designed device and five different irreversible
hydrocolloid impression materials. A total of 245 impressions were taken and divided
into a control group, two main groups and three subgroups through storing
procedure and time. Stone models were obtained for each model and five
different dimensions were measured and compared to each other.

Comparison of the groups according to brand of
irreversible hydrocolloid impression materials showed statistically significant
differences. While the storage period was statistically important at all
distances, storage condition was significant only at some distances.

Irreversible hydrocolloid impression materials can be
stored in holding solution or sealed plastic bags up to two weeks. Type of the
impression material, storage condition and storage period may affect
dimensions.
