Öğe An investigation of the validity of the Bedek models and Cameriere-European formula used in dental age prediction in Turkish children(Bmc, 2024) Gumusboga, Zekiye Seyma; Duruk, Gulsum; Ozdemir, Ecem; Aydan, Tuba; Kirgin, Ayse SuaraBackgroundDental age estimation is one of the most reliable methods for determining age, commonly used for forensic, criminal, and anthropological purposes. The purpose of this study was to assess and compare the precision of the Bedek models and the Cameriere-European Formula (CF) in determinating dental age in a sample of Turkish individuals.MethodsRetrospective panoramic radiographs of 1018 subjects (497 boys and 521 girls) aged 5-14 years were evaluated using the Bedek models and the CF. The differences between calculated dental age (DA) and chronological age (CA) for each sex and age group were analyzed using the paired sample t-test and the Wilcoxon signed-rank test. The accuracy of the methods used to estimate dental age was determined by calculating the mean absolute error (MAE) based on the proximity of the dental age to the chronological age.ResultsThe CF method overestimated CA by 0.1 year in the entire sample. Conversely, the Bedek models tended to overestimate CA, with the three-, four-, and seven-tooth models exhibiting the most significant difference. There was a statistically significant difference between boys and girls in the DA-CA calculation using the CF method in the entire sample. Among the Bedek models, the three- and four-tooth models had the lowest MAE in the entire sample, while the single-tooth model had the highest MAE.ConclusionThe CF method showed higher accuracy in predicting the age of children living in eastern Turkey compared to the Bedek Models.Öğe Dental travma sonrası daimi dişlerde kron kırıklarının modifiye eden baysal dental travma indeksi ile değerlendirilmesi ve tedavilerinin klinik takibi(İnönü Üniversitesi, 2025) Aydan, Tuba; Duman, SacideDental Travma Sonrası Daimi Dişlerde Kron Kırıklarının Modifiye Eden Baysal Dental Travma İndeksi ile Değerlendirilmesi ve Tedavilerinin Klinik Takibi Amaç: Travmatik dental yaralanmaların (TDY) sınıflandırılması; tedavi protokollerinin ve uzun dönem takibin bilimsel temellere dayanması, başarılı klinik sonuçlar alınması açısından kritik önem taşımaktadır. Bu tez araştırmasında kron kırığı şikayetiyle başvuran TDY hastalarının Modifiye Eden Baysal Dental Travma İndeksi (MEBDTİ) kullanılarak sistematik sınıflandırılması, uygun tedavilerinin yapılması ve tedavilerinin takip edilmesi amaçlanmıştır. Materyal ve Metot: Pedodonti Anabilim Dalına kron kırığı şikayetiyle başvuran 6- 14 yaş arası çocuk hastalar çalışmaya dahil edildi. Ebeveynlerin sosyodemografik, çocukların tıbbi, dental ve travma bilgileri kaydedildi. Yaralanmanın sınıflandırılması için MEBDTİ'yi içeren travma kayıt formu kullanıldı. Kron kırıklarının tedavileri tamamlandıktan sonra 1 yıllık tedavi takipleri yapıldı. Bulgular: Çalışmamıza 73 hastanın 102 daimi dişi dahil edilmiştir. Kron kırığının en sık görülme nedeni %64.4 oranla düşme, en sık etkilenen diş ise %98 oranla maksiller orta kesici diş olarak elde edilmiştir. Komplike kron kırığı görülen 27 dişin 18'ine (%66.7) cvek amputasyon, 5'ine (%18.5) endodontik tedavi, 4'üne (%14.8) direkt pulpa kuafajı uygulanmıştır. Komplike olmayan kron kırığı görülen 57 dişin 54'üne (%94.7) kompozit restorasyon, 3'üne (%5.3) indirekt pulpa kuafajı uygulanmıştır. Kırık tipi ile tedavi tipi arasında anlamlı ilişki elde edilmiştir (p<0.001). Sonuç: TDY'lerin MEBDTİ kullanılarak sistematik şekilde sınıflandırılması sayesinde, uygun tedavi yaklaşımları belirlenmiş; özellikle komplike kırıklarda cvek amputasyonu, komplike olmayan kırıklarda ise kompozit restorasyonun tercih edildiği ve başarılı sonuçlar verdiği görülmüştür.

Study Design A total of 888 panoramic radiographs from individuals aged 7 to 30 were annotated by 2 experts based on Demirjian’s A–H staging system. The proposed model, MorphMaskFormer , is built upon the classical UNet architecture, incorporating a lightweight transformer attention module inspired by Mask2Former. The model performs both binary (tooth/background) and multi-class (A–H stages) segmentation. Its performance was evaluated using IoU, Dice coefficient, Precision, Recall, and inference time, and compared against UNet, ResUNet, DeepLabV3+, PSPNet, and SegNet. Results MorphMaskFormer outperformed all baseline models, achieving a Dice score of 0.9461, IoU of 0.8985, and the fastest inference time at 78.59 ms. In multi-class segmentation, it showed high accuracy for stages A, D, and H, with an overall component accuracy of 72.41%. Conclusions MorphMaskFormer enables precise pixel-level segmentation of dental developmental stages, reducing inter-observer variability and shortening evaluation time. Its high accuracy and efficiency make it a scalable tool that enhances diagnostic confidence and supports critical clinical and forensic age-estimation decisions. © 2026 Elsevier Inc.Öğe Parental Awareness and Decision-Making in Enamel-Dentin Fractures in Permanent Teeth: The Role of Visual Case Scenarios(Wiley, 2025) Tirasci, Gizem; Aydan, Tuba; Duman, SacideAim This study aims to assess the impact of visual case scenarios on parental awareness and urgency perception regarding enamel-dentin fractures in children. Methods This descriptive study included parents of children aged 4-14 who were receiving active dental care. Data were collected via a structured questionnaire, which consisted of two sections: demographic characteristics and general knowledge questions, and visual case-based scenarios to evaluate trauma perception. Statistical analysis was conducted using descriptive methods and chi-square testing. Internal consistency was assessed using Cronbach's alpha. Results A total of 317 participants participated in the study; 65.9% of the participants were mothers and 56.8% had female children. A history of dental trauma was reported by 11.7% of parents. Regarding information sources, 50% relied on dentists or healthcare professionals, and 30.1% used the Internet. After a traumatic event, 42% preferred consulting a pediatric dentist, while 25.2% would visit a general dentist. 62.1% of participants could distinguish between primary and permanent teeth, but only 45.1% believed that the tooth type (primary or permanent) influenced treatment decisions. Regarding trauma concerns, 62.8% prioritized treatment for anterior teeth due to the risk of future complications. 96.8% acknowledged that the time elapsed since the trauma could affect treatment outcomes, and 72.2% considered fracture size important in treatment decisions. Furthermore, 87.1% did not view posterior tooth fractures as concerning as anterior ones. Conclusion This study highlights significant gaps in parental knowledge about pediatric dental trauma, stressing the need for improved education on trauma severity, timely intervention, and the impact of fracture size and tooth type on treatment.
