The effect of home-bleaching application on the color and translucency of five resin composites
Cengiz Yanardag, Esra
Objectives: The aim of this study was to investigate the effect of home bleaching agents on the color and translucency of resin composites. Methods: Thirty disc shaped specimens (1mm thick) were fabricated from each resin composite (Reflexions, Grandio, Gradia Direct, Clearfil Majesty Esthetic, Ceram-X Mono) and divided into 3 subgroups as carbamide peroxide (CP, Opalescence 10% PF), hydrogen peroxide (HP, 10% Opalescence Treswhite Supreme) and control group (n=10). Baseline CIE L*a*b* color coordinates were measured with spectrophotometer and translucency parameters (TP) were calculated. CP and HP groups were treated with bleaching agents according to manufacturers' instructions and control group was stored in distilled water (DW) for 14 days. Color and translucency measurements were...

Interfacial characteristics of BIOfactor MTA and Biodentine with dentin
Şimşek, Emine
The objective of this study was to characterize the interface between dentin and MTA-Angelus (Angelus, Londrina, Brasil), Biodentine (Septodont, France) and BIOfactor MTA (Imicryl, Konya, Turkey) using scanning electron microscopy (SEM), energy disperse X-ray spectroscopy (SEM-EDS) and confocal laser scanning microscopy (CLSM). Fifteen dentin segments were obtained from previously extracted singlerooted human teeth. Canal lumens were instrumented with diamond burs and then randomly filled with MTA-Angelus, Biodentine or BIOfactor MTA and placed in distilled water or Hanks' Balanced Salt Solution (HBSS) for 28-days. The samples were examined with SEM and the thickness of the interfacial layer measured. SEM-EDS analysis was performed to determine principal elemental composition...
Readability of Patient Information Texts About Apical Resection on Turkish Websites: Quantitative Research
Şimşek, Özge
Objectives The aim of this study is to analyze the readability levels and content adequacy of patient information texts available on the internet regarding apicoectomy. Material and Methods In the Google search (Google LLC, Mountain View, California, USA) using the keywords 'kök ucu ameliyatı,' the first 60 websites were examined. The patient information and education texts in Turkish were included. The obtained patient information texts were evaluated according to the Ateşman Readability Index. Additionally, it was assessed whether the text contents provided sufficient information about apical resection. The SPSS 23 statistical package program was used for data analysis. Within the scope of the study, the normal distribution of the data was calculated using the Kolmogo...
Farklı uygulama basamaklarında oluşan tükürük kontaminasyonunun 3 adeziv sistemin dentine bağlanma dayanımlarına etkisinin incelenmesi
Cengiz Yanardag, Esra
Amaç: Bu çalışmanın amacı, 3 farklı adeziv sistemin farklı uygulama basamaklarında oluşan tükürük kontaminasyonunun, adeziv sistemlerin dentine bağlanma dayanımları üzerine etkisini incelemektir. Gereç ve Yöntem: Yirmi dört molar dişin kullanıldığı çalışmamızda, mikro kesit alma cihazıyla her bir dişten 2 adet olmak üzere toplam 48 adet 1 mm’lik horizontal dentin kesidi elde edilmiş ve bu kesitler, test edilen adeziv sistemin tipine göre (Prime Bond NT, Clearfil SE Bond, Clearfil S3 Bond) rastgele 3 gruba ayrılmıştır. Daha sonra her adeziv sistem için biri kontrol grubu olmak üzere tükürük kontaminasyonunun olduğu aşamaya göre (adeziv öncesi, adeziv sonrası ve polimerizasyon sonrası) 4 alt grup oluşturulmuştur. Her dentin diski üzerine 3 adet 0.7 mm çapında ve 1 mm yüksekliğinde kompozi...
Comparison of zygoma plates and infrazygomatic crest miniscrews used open bite treatment: A 3-dimensional finite element study
Arslan Çarpar, Kübra
Introduction: This study aimed to evaluate infrazygomatic crest (IZC) miniscrews, which represent a new approach to maxillary posterior tooth intrusion and extra-alveolar skeletal anchorage, using 3-dimensional f inite element stress analysis to predict the clinical usability instead of zygoma plates. Methods: Six different models were developed. The direction of the intrusion force was generated parallel to the maxillary first molar, and the posterior bite-block intrusion appliance was connected with 2 steel arches. A zygoma plate, stainless steel (SS)-IZC miniscrew, and a titanium alloy (TiA)-IZC miniscrew were used as anchorage units, and 200 g and 400 g of intrusion forces were applied. The cortical bone, spongious bone, stress values, and displacements in the anchorage unit were exami...
Skleroderma’lı Hastaya Multidisipliner Yaklaşım ve 2 Yıllık Takip: Olgu Raporu
Cengiz Yanardag, Esra
Skleroderma, konnektif dokunun anormal sentezi sonucunda ortaya çıkan fibrotik değişiklikler ve vasküler deformiteler ile karakterize, sebebi bilinmeyen, organ ve sistemleri tutmaya eğilimli sistemik ve kronik bir bağ dokusu hastalığıdır. Sıklıkla oral ve perioral dokuları etkileyen sklerodermanın rijit bir dil, kısıtlanmış ağız açıklığı ve kserostomi gibi karakteristik özellikleri vardır. Bu vaka raporu sınırlı bir ağız açıklığı olan sistemik sklerozis hastasına interdisipliner bir tedavi yaklaşımını sunmaktadır. Hastanın molar dişine kanal tedavisi yapılmış ve diş eksiklikleri sabit bölümlü protezlerle rehabilite edilmiştir. 2 yıllık takip sonucunda tedavilerin başarılı olduğu gözlenmiştir.
REJENERATİF ENDODONTİK TEDAVİDE NÖRAL REJENERASYON
Şimşek, Emine
Pulpa, dişin içindeki tek yumuşak dokudur. Diş pulpası pulpa odasında yer alır ve dentin ile çevrilidir. Pulpa dokusu, dar apikal foramen ile periapikal dokuya bağlanır (Nör, 2006; Fan ve ark., 2015). Diş gelişimi, beslenme, sinirsel ve fizyolojik durumlarda savunma gibi birçok işlevi vardır. Pulpa çürük veya aşınma gibi anormal dış uyaranlara maruz kaldığında, pulpayı korumak için tersiyer dentin oluşturarak savunma tepkisi gösterir. Pulpa dokusu; odontoblastlara oksijen ve besin sağlayarak, zengin sinir dağılımı yoluyla duyu fonksiyonunu yerine getirerek ve bağışıklık veya inflamatuar hücrelerini savunmaya katarak dentinin canlılığını korur (Hashemi-Beni ve ark., 2017). Kök kanal tedavisi (KKT), pulpal ve periapikal hastalıkların en etkili ve yaygın tedavisi olarak bilinir. Kö...
The impact of language differences on the readability, quality, and reliability of information provided by artificial intelligence chatbots regarding vital pulp therapy: a cross-sectional study
Şimşek, Emine
Background: The increasing use of artificial intelligence (AI) chatbots in healthcare has highlighted the need to evaluate the accuracy, reliability, and readability of the clinical information they provide. Vital pulp therapy is one of the fundamental biological approaches in modern dentistry aimed at preserving pulp vitality, and the quality of information related to this topic is highly important for clinical decision-making. The present study aimed to assess whether the readability, quality, and reliability of information provided by six different AI-based chatbots (ChatGPT, ChatGPT-4o, Gemini, Microsoft Copilot, Perplexity, and Claude) regarding vital pulp therapy vary depending on language differences. Methods: After a comprehensive literature review, 12 questions related to vital pu...
