    Evaluation of shaping ability of different glide path instruments: a micro-computed tomography study
    (Bmc, 2023) Ozata, Merve Yeniceri; Falakaloglu, Seda; Keles, Ali; Adiguzel, Oezkan; Gundogar, Mustafa
    Background This study aimed to compare the shaping ability of different instruments, TruNatomy Glider (TRN-G), WaveOne Gold Glider (WOG-G), and ProGlider (Pro-G) using micro-computed tomography (micro-CT). Methods The mesial canals of 27 mandibular molars with two separate mesial canals and moderate curvature were included in this study [n = 27 mesiobuccal (MB) and mesiolingual (ML) root canal]. According to the manufacturer's instructions, the glide path was created with TRN-G, WOG-G, and Pro-G glide path instruments (n = 9 MB and ML root canal in each group). Micro-CT scanning was performed before and after preparation. Mesiodistal (MD) and buccolingual (BL) transportation and the centering ratio were measured at three levels within the canal (3, 5 and 7 mm). A three-way robust ANOVA was used to compare the parameters. Results TRN-G showed significantly greater transportation in the MD direction than the other instruments throughout the root canal (overall root canal) (p < 0.05). The best centering ability in the BL direction was shown by the WOG-G, regardless of level within the canal and canal distinction (MB vs. ML) (p < 0.05). There was no significant difference between groups according to the level within the canal and canal parameters (p > 0.05). Whether the root canal was MB or ML did not affect centering or transportation (p > 0.05). Conclusions Glide path instruments can be used to shape moderately curved canals with minimal apical transportation and better centering ability. All three tested glide path files can used safely before the shaping file.

    Is it safe to use YouTube™ to learn about root canal preparation? Analysis of content and quality of videos
    (Ariesdue Srl, 2023) Falakaloglu, Seda; Ozata, Merve Yeniceri; Karaagac, Betul; Gundogar, Mustafa
    Aim: This study assessed the quality, educational content, and demographics of root canal preparation videos on YouTube (TM). Methodology: The study was performed for root canal preparation using the keywords root canal shaping, root canal preparation, and root canal instrumentation on YouTube (TM). In total, 108 English language videos shorter than 15 minutes were acquired. After evaluating the demographic characteristics, the viewing rates of the videos were estimated. The quality of the videos was assessed using DISCERN, the Global Quality Scale (GQS), and the Video Power Index (VPI). Statistical analyses of the evaluated results were performed. Results: Endodontists uploaded the most videos (32%), mainly shot on the teeth of patients (30%). The number of views and the VPI were significantly higher for the videos uploaded by commercial companies than by endodontists (p<0.05), with no significant difference between videos uploaded by dentists or endodontists. As the DISCERN (reliability) value increased, the number of views/likes and the VPI increased, even though these values were not statistically significant (p>0.05). While a positive and meaningful relationship was found between DISCERN and the GQS (p<0.05), a negative and significant association was found between the VPI and the interaction index (p<0.05). When dentists, commercial companies, and others were considered as a single group and compared with endodontists, no significant difference was found between the two groups in terms of GQS and DISCERN (p>0.05). Conclusion: It was highlighted that a high-quality contribution from uploaders is needed for videos posted on YouTube (TM) about root canal preparation. It is crucial to refer to high-quality sources of information.

    Shaping ability of different NiTi rotary systems during the preparation of printed mandibular molars
    (Wiley, 2023) Falakaloglu, Seda; Silva, Emmanuel Joao Nogueira Leal; Yeniceri Ozata, Merve; Gundogar, Mustafa
    This study aimed to evaluate the shaping ability of XP-endo Shaper, TruNatomy and EdgeFile X3 during the preparation of resin-printed mandibular molar mesial root canals. Thirty-three resin-based mandibular mesial roots with two canals, obtained from extracted tooth cone-beam computed tomography (CBCT) image and printed on a three-dimensional (3D) printer, were divided into three experimental groups according to the different nickel-titanium (NiTi) systems used for root canal preparation. The specimens were scanned using CBCT imaging before and after root canal preparation. Then images were registered using a dedicated software and changes in the canal area, volume, untouched canal surface and the maximum and minimum dentine wall wear were calculated. The XP-endo Shaper instruments showed improved shaping ability with lower untouched root canal surface and better preservation of root canal anatomy during the preparation of resin-printed mandibular mesial root canals compared with TruNatomy and EdgeFile X3 systems.
