Femtosecond laser microstructuring of alumina toughened zirconia for surface functionalization of dental implants

The continuous need for high-performance implants that can withstand mechanical loads while promoting implant integration into bone has focused recent research on the surface modification of hard ceramics. Their properties of biocompatibility, high mechanical and fatigue resistance and aesthetic color have contributed to its succefull applications in dentistry. Alumina toughened Zirconia (ATZ) has been gaining attention as a material for dental implants applications due to its advanced mechan...

Anti-sessile bacterial and cytocompatibility properties of CHX-loaded nanohydroxyapatite

Nanohydroxyapatite possesses exceptional biocompatibility and bioactivity regarding bone cells and tissues, justifying its use as a coating material or as a bone substitute. Unfortunately, this feature may also encourage bacterial adhesion and biofilm formation. Surface functionalization with antimicrobials is a promising strategy to reduce the likelihood of bacterial infestation and colonization on medical devices. Chlorhexidine digluconate is a common and effective antimicrobial agent used ...

Does the introduction of gluten-free diet influence the prevalence of oral soft tissue lesions in celiac disease?

Aims and Objectives: Celiac disease (CD) is characterized by oral manifestations in the soft tissues. The introduction of a gluten-free diet (GFD) may be related to change in the prevalence of oral changes and symptoms. The aim of the study was to evaluate the prevalence of oral soft tissue lesions in a pediatric Portuguese population with CD compared with healthy controls, and secondarily to assess the relationship between the onset of the GDF and the prevalence of oral manifestations.
