Objectives: The purpose of this study was to utilize a no-code computer vision platform to develop, train, and evaluate a model specifically designed for segmenting dental restorations on panoramic radiographs.
Methods: One hundred anonymized panoramic radiographs were selected for this study. Accurate labeling of dental restorations was performed by calibrated dental faculty and students, with subsequent final review by an oral radiologist. The radiographs were automatically split within the platform into training (70%), development (20%), and testing (10%) subgroups. The model was trained for 40 epochs using a medium model size. Data augmentation techniques available within the platform, namely horizontal and vertical flip, were utilized on the training set to improve the model's predictions. Post-training, the model was tested for independent predictions. The model's diagnostic validity was assessed through the calculation of sensitivity, specificity, accuracy, precision, F1-score by pixel and by tooth, and by ROC-AUC.
Results: A total of 1,108 restorations were labeled on 960 teeth. At a confidence threshold of 0.95, the model achieved 86.64% sensitivity, 99.78% specificity, 99.63% accuracy, 82.4% precision and an F1-score of 0.844 by pixel. The model achieved 98.34% sensitivity, 98.13% specificity, 98.21% accuracy, 98.85% precision and an F1-score of 0.98 by tooth. ROC curve showed high performance with an AUC of 0.978.
Conclusions: The no-code computer vision platform used in this study accurately detected dental restorations on panoramic radiographs. However, further research and validation are required to evaluate the performance of no-code platforms on larger and more diverse datasets, as well as for other detection and segmentation tasks.
Clinical Significance: The advent of no-code computer vision holds significant promise in dentistry and dental research by eliminating the requirement for coding skills, democratizing access to artificial intelligence tools, and potentially revolutionizing dental diagnostics.

Background: The success of a restoration largely depends on the quality of its fit. This study aimed to investigate the fit quality of monolithic zirconia veneers (MZVs) produced through traditional and digital workflows.
Methods: A typodont maxillary right central incisor was prepared.

Objective: To evaluate the shear bond strength (SBS) and adhesive remnant index (ARI) scores of metal brackets to glazed lithium disilicate reinforced glass-ceramics and zirconia according to various surface treatment protocols.
Methods: A total of 240 lithium disilicate ceramic (LD) and 240 zirconia (Zr) blocks were randomly divided according to sandblasting, hydrofluoric acid (HF) etching, universal primer use, and the adhesive system applied. A maxillary canine metal bracket was bonded to each sample with resin cement (Transbond XT, TXT).

Objectives: This double-blind randomised crossover trial aimed to compare the aesthetic outcomes of CAD-CAM manufactured provisional restorations created using cone beam computed tomography (CBCT) and intraoral scanners (IOS) acquisition methods.
Methods: Twelve participants (mean-age: 38 ± 5 years) requiring full mouth rehabilitation were included in this crossover trial. Two sets of identical CAD-CAM provisional restorations, differing only in the method of data acquisition (A: CBCT, B: IOS), were fabricated.

Objective: To evaluate the 36-month clinical performance of Single Bond Universal Adhesive (SBU; 3M ESPE, Germany) in non-carious cervical lesions (NCCLs) using different modes of adhesion according to the FDI criteria. The primary outcome was the retention loss of the restorations, while the secondary outcomes included marginal staining, marginal adaptation, post-operative sensitivity and tooth vitality, recurrence of caries erosion and abfraction, and tooth integrity, all evaluated according to the FDI criteria.
Materials And Methods: In this study, the SBU Adhesive was applied to 246 NCCLs of 25 patients using different modes of adhesion: Self-etch (SE), selective-enamel-etching (SLE), and etch-and-rinse (ER).

Objective: To compare the translucency and contrast ratio of 13 different resin based restorative materials and to evaluate the effect of 2 different bleaching methods on the translucency and contrast ratio of these materials.
Methods: In this study, a total of 260 samples were prepared, 20 from each of 13 different dimethacrylate-based restorative materials. Then, each material group was divided into 4 subgroups.
