Effect of Cervical Margin Relocation With Different Injectable Restorative Materials on Fracture Resistance of Molars Received MOD CAD/CAM Onlay Restorations.
J Esthet Restor Dent
January 2025
Operative Department, Faculty of Dentistry, Mansoura University, Mansoura, Egypt.
Objective: To investigate the effect of cervical margin relocation with four different injectable restorative materials on the fracture resistance of molars receiving mesio-occluso-distal CAD/CAM nanoceramic onlay restorations.
Materials And Methods: One hundred and five sound mandibular molars received a standardized mesio-occluso-distal onlay preparation, with cervical margins located 2 mm apical to the cemento-enamel junction. The molars were randomly allocated into five groups (n = 21) according to the cervical relocating materials used: Group I had no cervical margin relocation; Group II used a highly viscous glass ionomer; Group III used a highly-filled injectable resin composite; Group IV used a resin-modified glass ionomer; and Group V used a bioactive ionic resin.
The Effect of Polyethylene Fiber and Flowable Resin Composite on Fracture Resistance in the Restoration of Large MOD Cavities.
J Esthet Restor Dent
January 2025
Department of Restorative Dentistry, Faculty of Dentistry, Kırıkkale University, Kırıkkale, Türkiye.
Objective: This in vitro study aims to evaluate the effect of placing polyethylene fibers used in large Class II MOD (mesio-occlusion-distal) cavities into different flowable resin composites and in different positions on the fracture resistance of the restoration.
Materials And Methods: Ninety healthy human molars were used in the study. No treatment was performed on 10 of these teeth and they were used as the control group.
Influence of the Type of Bulk-Fill, Resin-Based Composite on Internal Adaptation in Class V Restorations.

Department of Stomatology, The Second People's Hospital of Hefei and Hefei Hospital Affiliated to Anhui Medical University, Hefei, Anhui, China.
Objective: To investigate the effects of bulk-fill, resin-based composite types (high or low viscosity) on the internal adaptation of Class V restorations.
Study Design: Experimental study. Place and Duration of the Study: Hefei Stomatological Hospital, Hefei, China, from October 2022 to December 2023.
Evaluation of the corrosion resistance of bronze patina or/and protective coating on the surface of the archaeological coins.

Physical Chemistry Department, National Research Centre, 33 El Bohouth Street, P.O.12622, Dokki, Giza, Egypt.
Archaeological coins are considered essential sources of historical documentation. Over time, they are subjected to corrosion processes that gradually alter their appearance, shape, and composition. This study aims to evaluate the effects of the patina and/or protective coating on the corrosion process.

In clinical scenarios, bone defects stemming from trauma, infections, degenerative diseases, or hereditary conditions necessitate considerable bone grafts. Researchers ardently focus on creating diverse biomaterials to expedite and enhance these intricate restorative processes. These biomaterials play a pivotal role in aiding osteogenesis and angiogenesis factors for reconstructing stable, fully developed bone tissue.
