    Can ultrasonography be used to detect root perforation? An in vitro study
    (Wiley, 2025) Sarıyılmaz, Öznur; Eren, İrem; Sarıyılmaz, Evren; Eren, Hakan; Uslu, Gülşah
    This study assessed the usability of ultrasonography in detecting root canal perforations. The buccal side of incisor root were perforated. The actual lengths up to the perforation site were measured by visualisation of the tip of a file. Specimens were embedded in gypsum, and it was scraped to simulate bone resorption. Resorption cavities were filled with ultrasound gel. Measurements were taken by advancing a file through the canal until the tip became visible in the ultrasound image. 3D scans were obtained using cone-beam computed tomography (CBCT) and the distance between the coronal point of the resorption cavity and the reference point was measured. The actual distance of the resorption cavity from the reference point varied 6-10.6 mm. The same distances were measured via ultrasound as 5.7-10.9 mm, while measured using CBCT 6-10.5 mm. No significant differences were found. Ultrasonography shows promise for detecting root perforations, however further research is needed.

    Comparison of the Effects of WaveOne Gold, TruNatomy, and Conventional Hand Files on Remaining Dentin Volume in the Coronal Part of the Root and Preparation Efficiency in Mandibular Molars
    (Elsevier Inc., 2023) Eren, İrem; Sezer, Berkant
    Introduction: The use of file systems that work with different principles in root canal treatment is becoming widespread. The aim of this study was to evaluate the remaining dentine volume in the coronal region of the root and preparation efficiency after the use of conventional hand files, WaveOne Gold; which works with reciprocating motion, and TruNatomy; which works with rotational motion in the root canal treatment of mandibular molar teeth. Methods: All canals of permanent mandibular molars (n = 36) were used. Root canals in each group (n = 12) were prepared with conventional hand files, WaveOne Gold, and TruNatomy. The three-dimensional images were evaluated for remaining dentine volume in the coronal two-millimeter region of the root and change in volume of the entire root canal space. Results: There was no statistically significant difference between the groups in terms of mean differences pre and postpreparation (P > .05). The mean differences after preparation were observed the most in the WaveOne Gold group and the least in the TruNatomy group in the coronal two-millimeter region of the root and entire canal volume, but the differences were not significant (P > .05, P > .05, respectively). Conclusions: Conventional hand files, WaveOne Gold working with reciprocating motion, and TruNatomy working with rotational motion, which are the file systems used in the study, are not superior to each other in terms of remaining dentin volume in the coronal two-millimeter region of the root and preparation efficiency in the entire root canal space in mandibular molars.

    Quantitative Comparıison of The Preparation Efficiencies of Two Different Rotary File Systems in Permanent Mandibular Molars
    (Zonguldak Bulent Ecevit University, 2024) Eren, İrem; Sezer, Berkant
    Aim: Use of different rotary file systems in permanent teeth, in the preparation phase of root canal treatment, is becoming increasingly common. The amount of dentin remaining after preparation is important for prognosis of treatment. The aim of this study was to evaluate residual dentin weight and preparation efficiency after using of the WaveOne Gold and TruNatomy file systems in root-canal treatment of mandibular molars. Material and Methods: This study was carried out on 30 permanent mandibular molars, which were extracted for various reasons. Firstly, access cavities of teeth were prepared and weights of them were recorded with precision scales that can show five decimal places before the preparation. Root canals in each group (n=15) were prepared with WaveOne Gold and TruNatomy file systems. After preparation, weights of all teeth were re-measured and recorded. Results: There was no statistically significant difference between pre- and post-preparation mean weights in both groups. When average weight reductions between the groups were compared, the average weight reduction in WaveOne Gold group was statistically significantly higher than TruNatomy group (p < 0.05). Conclusion: WaveOne Gold rotary file system can remove a larger amount of dentine and pulp tissue than TruNatomy rotary file system
