Publication Metadata only Attitudes and perceptions of dental students towards artificial intelligence(John Wiley and Sons Inc, 2021) Yüzbaşıoğlu, Emir; Yüzbaşıoğlu, Emir, Department of Prosthodontics, Bahçeşehir Üniversitesi, Istanbul, Turkey, Department of Dentistry, BAU International University, Batumi, GeorgiaIntroduction: Artificial Intelligence (AI) is a burning topic and use of AI in our day-to-day life has increased exponentially. The purpose of this study was to evaluate the attitudes and perceptions of Turkish dental students towards AI and to provide information about their opinions to use of AI in dentistry. Methods: A 22-question survey was distributed through Google Forms to all dental students at 9 Turkish dental schools in March 2019. It consisted of various sections aiming to evaluate the dental students’ knowledge and attitudes toward AI and possible applications in dentistry. Respondents’ anonymity was ensured. Results: A total of 1103 students (650 female, 453 male, mean age was 21.36 ± 1.93 years) responded to the questionnaire for a 21.69% response rate. Of these, about 48.40% had basic knowledge about AI technologies and 10.6% stated that they had no information sources about AI. 85.70% agreed that dentistry would be revolutionized by AI but 28.60% did not agree that AI could replace themselves in the near future. In addition, 74.60% and 79.80% of agreed on topics about AI to be included in undergraduate and postgraduate dental education, respectively. Conclusions: Although participants have insufficient knowledge of AI, they are willing to improve their knowledge in this field. Participants shared an optimistic views and thought that AI will have a positive impact on dental future practice. Follow-up surveys and multinational studies should be conducted to further explore these issues. © 2020 Elsevier B.V., All rights reserved.Publication Metadata only CAD/CAM single-retainer monolithic zirconia ceramic resin-bonded fixed partial dentures bonded with two different resin cements: Up to 40 months clinical results of a randomized-controlled pilot study(John Wiley and Sons Inc, 2022) Bilir, Halenur; Yüzbaşıoğlu, Emir; Sayar, Gülşilay; Kılınç, Delal Dara; Gozukara Bag, Harika Gozde; Özcan, Mutlu; Bilir, Halenur, Department of Prosthodontics, İstanbul Medipol Üniversitesi, Istanbul, Turkey; Yüzbaşıoğlu, Emir, Department of Prosthodontics, Bahçeşehir Üniversitesi, Istanbul, Turkey; Sayar, Gülşilay, Department of Orthodontics, Bahçeşehir Üniversitesi, Istanbul, Turkey; Kılınç, Delal Dara, Private Practice, Istanbul, Turkey; Gozukara Bag, Harika Gozde, Department of Biostatistics, Inönü Üniversitesi Tip Fakültesi, Malatya, Turkey; Özcan, Mutlu, Dental Materials Unit, Universität Zürich, Zurich, SwitzerlandPurpose: This pilot study was part of a larger study planned for the future which aimed to compare the clinical success of two different resin cements used in the cementation of CAD/CAM single-retainer monolithic zirconia ceramic resin-bonded fixed dentures (RBFPDs). Methods: Twenty-four RBFPDs were fabricated with monolithic zirconia (Katana™ Zirconia HT, Kuraray Noritake Dental Inc, Tokyo, Japan). Panavia F2.0 (PF2.0, n = 12) and Panavia V5 (PV5, n = 12) were used for cementation. The survival period was defined as the time when the restoration was placed in the mouth and lasted until an irreparable damage occurred. The repairable failures were identified as relative and irreparable failures were identified as absolute failure. The survival rate of the RBFPDs was determined by the Kaplan–Meier estimator. Statistical significance was set at p < 0.05. Results: The mean observation times of the PF2.0 group and the PV5 group were 40.45 ± 6.15 months and 40.18 ± 6.41 months, respectively. Four failures occurred in the PF2.0 group. No failure was observed in the PV5 group. The curves of survival rate (PF2.0 = 80%, PV5 = 100%) showed no statistically significant difference (p = 0.031), although success rate (PF2.0 = 66.7%, PV5 = 100%) showed statistically significant difference (p = 0.317). Conclusion: Up to 40 months mean follow-up period, performance of RBFPDs bonded with PV5 was better than with PF2.0. Clinical Significance: For clinicians, it is a matter of hesitation to apply single-retainer RBFPDs. This study contains results of 40 months (minimum 32, maximum 50.47 months) clinical follow-ups of single-retainer RBFPDs. These results will enlighten clinicians about the clinical success of the resin cement type for single-retainer monolithic zirconia ceramic RBFPDs. © 2022 Elsevier B.V., All rights reserved.Publication Metadata only Clinical Evaluation of Low-shrinkage Bioactive Material Giomer Versus Nanohybrid Resin Composite Restorations: A Two-year Prospective Controlled Clinical Trial(NLM (Medline), 2023) Toz-Akalin, Tuǧba; Ozturk-Bozkurt, Funda; Kuşdemir, Mahmut; Özsoy, Alev; Yüzbaşıoğlu, Emir; Özcan, Mutlu; Toz-Akalin, Tuǧba, Department of Restorative Dentistry, Bahçeşehir Üniversitesi, Istanbul, Turkey; Ozturk-Bozkurt, Funda, Department of Restorative Dentistry, İstanbul Medipol Üniversitesi, Istanbul, Turkey; Kuşdemir, Mahmut, Department of Restorative Dentistry, İstanbul Medipol Üniversitesi, Istanbul, Turkey; Özsoy, Alev, Department of Restorative Dentistry, İstanbul Medipol Üniversitesi, Istanbul, Turkey; Yüzbaşıoğlu, Emir, Department of Prosthetic Dentistry, Bahçeşehir Üniversitesi, Istanbul, Turkey; Özcan, Mutlu, Clinic of Reconstructive Dentistry, Universität Zürich, Zurich, SwitzerlandThis study evaluated the clinical performance of low-shrinkage bioactive resin composite compared with a conventional nanohybrid resin composite. A total of 35 patients (18 males, 17 females, mean age: 29±9 years old) received, randomly, 35 pairs of fillings restored with either low-shrinkage bioactive material employing Giomer filler technology (Beautifil II LS, Shofu Inc, Kyoto, Japan) or conventional nanohybrid resin composite (Clearfil Majesty Posterior, Kuraray, Japan) in Class I and Class II cavities. Two operators made all the restorations using the corresponding adhesive resins: FL-Bond II (Shofu Inc) and Clearfil SE Bond (Kuraray), according to each manufacturer's instructions. Two calibrated operators evaluated the restorations two weeks after placement (baseline), at six months, and at one and two years using FDI criteria (Scores 1-5). Data were analyzed using the McNemar test (α=0.05). Mean observation time was 27.4 ± 4.1 months (min=20.8, max=33.7). In both groups, according to FDI criteria, the restorations were mostly rated with best scores (Score 1 or 2) for biological, functional, and optical parameters. For one filling in the group restored with nanohybrid resin composite, a small and localized secondary caries lesion was observed and monitored at the one- and two-year follow-ups. One restoration in the low-shrinkage Giomer restorative group was accepted as a failure due to retention loss. Over the two-year follow-up, both the Giomer and the nanohybrid resin composite restorations' performance was clinically acceptable.

The aim of this study is to determine the course and morphological characteristics of the mental foramen (MF) and the mandibular incisive canal (MIC) in Turkish society. Cone Beam Computed Tomography (CBCT) is considered the gold standard for dental imaging, therefore, in this study 96 CBCT images were examined retrospectively. The width and the length of the MF, distance from the MF to the alveolar bone crest, lower border of the mandible, angulation of mental canal to buccal bone surface, the length of the MIC, the angle among mental foramenincisive canal and a horizontal plane parallel to the inferior border of the mandible, and the height of the angle were measured. At the endmost point of the MIC, the distance between the canal and inferior, labial, and lingual borders of the mandible was measured. The most common locations of MF were along the second premolar (23.4%). MIC was absent in 24.4% of the cases. The most common locations of the endmost point of MIC were along the first incisive (35.8%), MIC length was significantly longer in males. Although the structures show variation among individuals, the mean values in Turkish society are similar to the mean values in the literature. © 2023 Elsevier B.V., All rights reserved.Publication Metadata only How do various mouth rinses influence the color stability of CAD-CAM resin-based restorative materials?(Elsevier Inc., 2025) Turker Kader, Izim; Yüzbaşıoğlu, Emir; Smail, Ferruh Semir; Ilhan, Ceylan; Turker Kader, Izim, Department of Prosthodontics, Bahçeşehir Üniversitesi, Istanbul, Turkey; Yüzbaşıoğlu, Emir, Private Practice, Istanbul, Turkey; Smail, Ferruh Semir, Dental Prosthetic Technology, Bahçeşehir Üniversitesi, Istanbul, Turkey; Ilhan, Ceylan, Vocational School of Health Services, Bahçeşehir Üniversitesi, Istanbul, TurkeyStatement of problem: The color stability of computer-aided design and computer-aided manufacture (CAD-CAM) resin-based materials can be affected by their composition and exposure to different mouth rinses. However, the impact of different mouth rinse formulations on these materials remains unclear. Purpose: The purpose of this in vitro study was to investigate the effect of different mouth rinses on the color stability of CAD-CAM resin-based materials over time. Material and methods: A total of 180 specimens of 5 CAD-CAM resin-based materials were fabricated: a polymer-infiltrated ceramic network (PICN) (Vita Enamic, ENA), resin nanoceramics (GC Cerasmart, CERA, Brilliant Crios, BRC), a resin nanohybrid (Grandio, GRD), and a resin composite (KZR-CAD HR2, KZR). A lithium disilicate ceramic (IPS e.max CAD, EMX) served as the control (n=30). Specimens were immersed in alcohol-containing (Listerine Cool Mint, LIS), alcohol-free (Oral-B complete, ORLB), zinc-chloride containing (Pharmol Zn, PHR), hypochlorous acid-containing (Briotech Pure, BRT) mouth rinses, and artificial saliva (CON) for 12 hours (t0.5), 2.5 days (t2.5), and 5 days (t5) of simulated exposure equivalent to 1, 5, and 10 years. Color differences (ΔE00) were calculated at each time point. The effects of material, mouth rinse, and time were analyzed using 3-way robust ANOVA with Bonferroni post hoc tests (α=.05). Results: EMX exhibited the highest color stability, while the GRD showed the largest discoloration (P<.001). LIS and ORLB mouth rinses caused significantly higher ΔE00 values than other solutions (P<.001). Discoloration increased with longer exposure times (P=.001). Among all groups, BRC immersed in LIS exhibited the most pronounced color change, while EMX in CON showed the least (P=.001). Conclusions: CAD-CAM resin-based materials undergo a larger color change than lithium disilicate ceramic, with variations depending on composition and mouth rinse type. While alcohol-containing mouth rinse (LIS) induced the highest discoloration, particularly in the resin nanoceramic (BRC), the highest discoloration after a simulated prolonged exposure of 10 years was observed in the resin nanohybrid (GRD). Notably, the alcohol-free ORLB also led to significant discoloration, suggesting that other ingredients beyond alcohol contribute to staining. © 2025 Elsevier B.V., All rights reserved.
