The objective of this work was to evaluate the prevalence of children with crown fractures in permanent anterior teeth in 206 schoolchildren (104 girls and 102 boys) between the ages of 8 and 10 years, enrolled in three public schools in the city of Canoas, Brazil. The prevalence found was 17% with no significant difference between boys and girls, as well as between the ages. The most affected tooth was the maxillary central incisor, and a majority of the children showed only one affected tooth (88.6%). The types of fracture most commonly found were oblique and horizontal, and the portions of dental structures most affected were 'enamel only' and 'enamel and dentin'. Only seven children (20%) sought out dental treatment.

This position statement is a consensus view of an expert committee convened by the European Society of Endodontology (ESE). The statement is based on current clinical and scientific evidence as well as the collective reflective practice of the committee. The aim is to provide clinicians with evidence-based, authoritative information on the aetiology, clinical presentation, and management of cracks and fractures that typically manifest along the long axis of the crown and/or root.

Aim To evaluate and compare the fracture toughness and flexural strength of interim fixed partial dentures reinforced with carbon, glass, and Kevlar nanofibers. Materials and methods This study explored the effect of reinforcing poly methyl methacrylate with carbon, glass, and Kevlar fibers on its fracture toughness and flexural strength. A total of 120 samples were prepared, divided into two groups of 60 samples each, with one group tested for fracture toughness and the other for flexural strength.

Background: Increasing demand for durable and aesthetically pleasing dental restorations, including laminates, inlays, onlays, and crowns, has led to advancements in all-ceramic systems, particularly with the development of advanced lithium disilicate materials. However, limited data on the fit accuracy and fracture resistance of these materials restricts their wider application in clinical restorative practices.
Aim Of The Study: This in vitro study aims to compare the marginal and internal fit, assess the fracture resistance, and evaluate the failure modes of crowns fabricated from advanced and conventional lithium disilicate materials.
Long-Term Clinical Study on Sandblasted-Acid-Etched Surface Dental Implants: 12-Year Follow-Up.

Sandblasting and acid etching are common procedures used to treat implant surfaces, enhancing osseointegration and improving clinical success rates. This clinical study aimed to evaluate the long-term outcomes of sandblasted and acid-etched implants. A total of 303 implants were placed in 114 partially and totally edentulous patients using a two-stage surgical technique and an early loading protocol (6-8 weeks).
