    Assessment of Undergraduate Dentistry Students’ Experiences and Self-Confidence Levels During Endodontic Treatment: A Cross-Sectional Survey Study
    (2022) Ali ERDEMİR; Ali TÜRKYILMAZ; Deniz Erdogan; Gozde Akbal Dincer; Endodonti / Endodontics
    Objective: The goal of this study is to compare experi ences and self-rated confidence levels between 4th and 5th year students across endodontic assignments. Material and Methods: A survey con sisting of 26 questions was organized at the termination of the academic year with the involvement of 4th and 5th year students studying at Kırıkkale University Faculty of Dentistry in accordance with the Princi ples of the Declaration of Helsinki. First 16 questions were about levels of confidence. Other questions prepared as multiple choices are about their experiences in endodontic procedures. The data obtained after col lecting the questionnaires were analyzed by using chi-square, Fisher’s exact and Mann-Whitney U tests at the 5% significance level. Results: One hundred and sixteen students (64 of 72 4th and 52 of 62 5th grade stu dents) answered the survey. The participation rate was 86.27%. The Grade-5 group felt statistically more confident about radiographic tech niques, determining the working length, mechanical instrumentation and filling of the root canals (p=0.030, p=0.001, p=0.011, p=0.020). Com paring mechanical instrumentation in maxillary and mandibular molars, the Grade-4 group felt statistically significantly confident in instrumen tation of the mandibular molars (p=0.000). The Grade-4 group felt sta tistically more confident in performing periapical radiographs of maxillary anterior teeth (p=0.000) and the Grade-5 group of mandibular molars (0.001). Additionally, students think that endodontics are more difficult than other dentistry departments (p=0.000). Conclusion: Within the limitation of this study, evaluating the major student difficulties dur ing endodontic treatment may improve teaching strategies throughout preclinical and clinical education.

    Effect of Different Irrigation Activation and Condensation Techniques on the Marginal Adaptation of White MTA
    (Galenos Publ House, 2023) Tuerkyilmaz, Ali; oezbay, Yagiz; Dincer, Gazde Akbal; Erdemir, Ali; Endodonti / Endodontics
    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.
