İKİ FARKLI KALSİYUM HİDROKSİT PREPARATININ ENDODONTİK TEDAVİ GÖREN DİŞLERİN DENTİN KIRILMA DİRENCİNE OLAN ETKİSİNİN İNCELENMESİ

Amaç: Bu çalışmanın amacı iki değişik karışımdaki kalsiyum hidroksit (KH) preparatının endodontik tedavi görmüş insan dişlerinde dentin kırılma direncine (DKD) olan etkisinin in vitro olarak incelenmesidir. Gereç ve Yöntem: Bu amaçla 90 adet çekilmiş çürüksüz insan alt çene ön kesici dişi kullanılmıştır. Dişler üç çalışma grubuna ayrılmıştır. Bütün gruplardaki dişlerin kök kanalları aynı yöntemle döner aletler kullanılarak hazırlanmıştır. Grup 1: KH ve steril serum fizyolojik. Grup 2: KH ve %2’lik klorheksidin glukonat (KHS). Grup 3: pozitif ve negatif kontrol (kök kanallarına herhangi bir KH preparatı uygulanmamıştır). 7, 14 ve 28 günlük sürelerin sonunda her grubun kendi içinden rastgele seçilen 10 diş İnstron cihazı kullanılarak DKD bakımından test edilmiştir. Bulgular: Elde edilen verilerin istatistiksel olarak incelenmesi ve karşılaştırılması sonucunda her iki KH preparatının, birbirleri ve pozitif kontrol grubu arasında DKD açısından istatistiksel olarak anlamlı bir fark bulunamamıştır (p=0,441). Sonuç: Bulgular her iki karışımında 4 haftalık sürelerde güvenli bir şekilde uygulanabileceğini göstermektedir.

Purpose: The aim of this in vitro study was to evaluate the effect of two different calcium hydroxide (CH) mixtures on the dentine fracture strength (DFS) of endodontically treated human teeth.Materials and Methods: For this purpose 90 extracted intact human mandibular incisors were used. The teeth were divided into three experimental groups. Group 1: CH and sterile saline solution mixture. Group 2: CH and %2 chlorhexidine gluconate (CHX) mixture. Group 3: positive and negative control groups (without any CH application). The DFS of randomly chosen 10 teeth of every group was measured in an İnstron testing machine on 7th, 14th or 28th day.Results: The results clearly indicated that there are no statistically significant difference neither between the saline and CHX mixture groups, nor the positive control group (p=0,441).Conclusion: Both mixtures of CH can be used safely up to 4 weeks as a root canal medicament.
