    Comparison of various irrigation activation procedures after post space preparation on push-out bond strength of fiber posts: an in vitro study
    (Pagepress Publ, 2021) Akbulut, Merve Ozguven; Ozbay, Yagiz; Erdemir, Ali
    Aim: To compare the effectiveness of various irrigation activation methods applied after post space preparation on the push- out bond strengths of fiber posts to root canal dentin. Materials and Methods: Twenty maxillary central incisor teeth were prepared and root-filled. Following the preparation of the post spaces, the teeth were randomly allocated to 5 groups (n=4) based on the irrigation activation method. Post spaces were irrigated with 2.5% NaOCl and 17% EDTA and various irrigation activation techniques were applied in each group as follow. Group 1: conventional syringe irrigation (CSI); Group 2: manual-dynamic activation (MDA); Group 3: negative apical pressure (EndoVac); Group 4: passive ultrasonic irrigation (PUI) and Group 5: Er,Cr:YSGG laser. Subsequent to fiber post placement, the samples were transversally sectioned and push-out tests were applied for measurement of the bond strength of fiber posts. Results: Irrigation activation with Er,Cr:YSGG laser, EndoVac and PUI resulted higher push-out bond strength in comparison to MDA and CSI (P<.05). Conclusions: Irrigation activation with EndoVac, PUI and Er,Cr:YSGG laser provides superior bonding strength for fiber posts.

    Effect of different irrigation activation and condensation techniques on the marginal adaptation of white mta
    (2023) Türkyılmaz, Ali; Özbay, Yağız; Dincer, Gozde Akbal; Erdemir, Ali
    Objective: To evaluate the effect of different irrigation activation and condensation techniques on the marginal adaptation ability of white ProRoot mineral trioxide aggregate (MTA). Materials and Methods: Eighty single-rooted human teeth were prepared to a ProTaper Universal F4 file. Initially, the roots were randomly divided into four groups as follows: conventional syringe irrigation in group 1, sonic activation (EDDY) in group 2, passive ultrasonic irrigation in group 3, and Er:YAG laser in group 4. Then, ProRoot MTA was set with hand condensation or ultrasonic condensation techniques, and the adaptation ability of MTA was investigated using SEM. Results: EDDY activation had the lowest gap scores (p<0.001). No statistical differences were observed between the regions (p>0.05), and condensation techniques (p>0.05). Conclusion: The marginal adaptation of ProRoot MTA to root dentine increased with EDDY activation, and the marginal adaptation ability of the material was not affected by the condensation technique.
