Cemento resinoso: ¿Todo cemento dual debe ser foto activado?

, 2009
Los cementos resinosos duales son agentes de cementación lanzados en el mercado con el fin de unir las características favorables de los cementos resinosos fotoactivados y de los autopolimerizados. Actualmente, son utilizados en situaciones donde existe la pérdida o la ausencia de luz debido a la distancia de la fuente activadora al agente cementante ...

Nucleoside‐Based Hydrogel Platform Synergizes with Photothermal Effects for Enhanced Biofilm Eradication Against Periodontitis

Advanced Science, Volume 13, Issue 13, 3 March 2026.
A synergistic antibiofilm hydrogel platform (ZBAg@FNP) is developed by encapsulating an organic small‐molecule photothermal agent (FNP) within a silver ion‐mediated supramolecular hydrogel (ZBAg), enabling photothermal disruption of biofilm integrity and controlled Ag⁺ ion release upon irradiation.

Preclinical Evaluation of the Effect of Liquid Platelet–Rich Fibrin and a Volume‐Stable Collagen Matrix on Periodontal Regeneration

Journal of Clinical Periodontology, Volume 53, Issue 3, Page 424-435, March 2026.
ABSTRACT Aim To evaluate the regenerative potential of liquid platelet–rich fibrin (PRF), with and without a volume‐stable collagen matrix (VCMX), in periodontal intrabony defects using histological, histometric and micro‐CT analyses. Materials and Methods One‐wall intrabony defects were surgically created in six beagle dogs and treated with either ...
