Farklı Gütaperka Çözücülerin Trikalsiyum Silikat İçerikli Simanların Kök Kanalına Bağlanma Dayanımı Üzerine Etkisi
Özet
The aim of this study was to evaluate the effect of three different gutta percha solvents and their different application times on the push-out bond strengths of ProRoot MTA and Biodentine. 80 single rooted mandibular premolar teeth with no cracks, fractures and resorption on the root surfaces were used. After removal of crowns, root canals were prepared by using ProTaper rotary nickel titanium system and then a standard diameter was obtained with peeso-reamers. Following preparation of root canals, two hundred and forty 1-mm-thick midroot sections were obtained. These dentin slices were divided into two groups according to the filling material. Group 1: ProRoot MTA, Group 2: Biodentine. These groups were randomly assigned into 3 different subgroups according to gutta-percha solvents. In these three subgroups, randomly assigned dentin slices were treated with the following solvents: Chloroform, eucalyptol and orange oil. Within each subgroup, the specimens were further divided into two and solvents were applied for either 5 or 10 minutes (min). Thereafter, solvents were removed by irrigating with distilled water and the slices were dried with air sprey. The root canal spaces of each slice were filled either with ProRoot MTA or Biodentine according to their groups. The push-out bond strength values were measured after 21 days. Data were analyzed using three way ANOVA with Bonferroni correction p = 0.05. The solvents and their application times didn’t statistically affect the bond strength of ProRoot MTA and Biodentine but for the subgroup treated with orange oil for 10 min, the push out bond strength of Biodentine was reduced significantly (p<0.05).
