Aims: Artificial intelligence refers to the ability of computer systems or machines to perform cognitive functions and tasks that are similar to humans’. The aim of this study is to assess the knowledge and interpretative abilities of ChatGPT-versions by administering a dentomaxillofacial-radiology exam, comparing its performance with that of dentistry-students in Türkiye, and questioning the effectiveness of different languages. Methods: It is a descriptive research comparing the data of ChatGPT versions 3.5 and 4 in both Turkish and English. Results: Firstly 20 test-questions were evaluated. There is a significant difference(p

Statement of the problem: It is unclear how the success of color selection with custom shade guides is influenced by the observer's level of color education and the type of light source. Objective: The aim of this study is to compare the color matching ability under different light sources between observers with and without color education and to investigate in which shade tabs they are more successful, using a custom-made shade guide. Materials & Methods: The study included 5 prosthodontists (PD), 5 general dentists (GD), 5 dental ceramists (DC), 5 removable denture technicians (RDT), and 10 participants with no color education (NP). Using dentin powder from feldspathic dental porcelain, 2 sets of 16 shade tabs matching those in the Vita Lumin Classic shade guide were produced. The Lab values of the produced shade tabs with the same shade code were measured using a colorimeter device, and those with ΔE values below 0.1 were used for shade matching. Each participant conducted a total of 48 shade matches under 3 different light sources (tungsten-TG, fluorescent-FL, and D65). Results: It was found that the shade matching success of dental professionals in the PD, GD, RDT, and DC groups significantly differed from that of the participants in the NP group (χ² = 23.417; P< 0.001). Shade matches conducted under the D65 light source were more successful than those under the TG and FL light sources, and participants were found to match shade tabs with higher saturation, such as A4 and C4, more successfully. Conclusions: Color matching performed with a custom color scale is influenced by the observer's training and the light source. As the saturation of shade tabs increases, the matching success also increases.

Objective: To determine the degree of knowledge, acceptance and use of CAD/CAM technology by investigating the sociodemographic characteristics of dental technicians participating in the survey.Methods: A web-based questionnaire consisting of a total of 25 questions and consisting of 4 sections was applied to 153 dental technicians. The first part of the questionnaire includes demographic information, the second part includes digital technology knowledge, the third part includes digital technology usage and the last part includes questions about the future of digital technology. In addition to descriptive statistics, the Pearson Chi-Square test and Fisher's Exact test were used to examine the effect of various variables.Results: The 43.2% of the participants were female and 56.8% were male. The 61% of the male dental technicians had significantly more professional experience than the female participants (P<.001). 57.5% of the participants had a diploma and the proportion of females was significantly higher than that of males (P<.001). 49% of the participants stated that their level of professional knowledge was sufficient and there was no significance in terms of gender or educational status (P>.05). 64.7% of the participants stated that they actively use digital technological devices regardless of gender and educational status. 98.3% of dental technicians stated that they would prefer to use new technological devices in the future.Conclusion: Most of the participants are actively using CAD/CAM technology and almost all of them plan to use it soon.Keywords: Dental technician, digital technology, 3D, CAD/CAM, survey.

AMAÇ: Bu çalışmanın implant cerrahisinin bilgisayar ortamında tasarlanması ve elde edilen cerrahi plaklar ile implant cerrahisinin gerçekleştirilmesidir. GEREÇ VE YÖNTEMLER : 65 yaşındaki kadın hasta kliniğimize yetersiz çiğneme fonksiyonu ve diş kayıpları şikayeti ile başvurmuştur. Yapılan intraoral ve radyografik muayenesi sonucunda implant destekli protezler ile tedavinin tamamlanmasına ve cerrahi esnasında cerrahi rehber plak kullanımına karar verilmiştir. Hastadan elde edilen BT görüntüleri eşliğinde bilgisayar ortamında implant pozisyonları planlanmış ve cerrahi gerçekleştirilmiştir. BULGULAR: Cerrahi sonrası alınan panoramik radyografide implantların istenilen vertikal konumda olmadığı fark edilmiş ve 48 saat anahtarı (ITI, Strauman, İsviçre) kullanılarak kemik seviyesine getirilmiştir. İmplant yerleşiminden 3 ay sonra tüm ağız rehabilitasyonu tamamlanmıştır. SONUÇ: Osseointegrasyon başlamadan 48 saat içerisinde implant pozisyonları değiştirilebilir. Yapılan tedavi sonucunda hasta yetersiz olan çiğneme fonksiyonunu ve estetik görünümünü tekrar kazanmıştır. ANAHTAR KELİMELER: Bilgisayar destekli implantoloji, dental implant, flepsiz cerrahi
