      Objective To characterize extracellular vesicles (EVs) in gingival crevicular fluid (GCF) and saliva samples from healthy/gingivitis and periodontitis patients and correlate them with clinical inflammatory periodontal ...
    • González Quesada, Jorge; Rivera Álvarez, Sonia (Universidad de Costa Rica, Facultad de Odontología, 2016)
      Pyridinoline (ICTP) is a molecule of collagen degradation that after bone resorption and degradation of the collagen matrix is released into the circulation and can not pass anabolic pathways and reused during collagen ...
    • Monasterio, Gustavo; Ormeño Castillo, Francisca; Astorga, Jéssica; Hoare Teuche, Anilei; Terraza, Claudia; Cafferata, Emilio A.; Villablanca, Eduardo J.; Vernal Astudillo, Rolando Marcelo (Frontiers Media, 2020)
      Aggregatibacter actinomycetemcomitans is a Gram-negative oral bacterium with high immunostimulatory and pathogenic potential involved in the onset and progression of periodontitis, a chronic disease characterized by aberrant ...
    • Dutzan Muñoz, Nicolás; Gamonal Aravena, Jorge Antonio; Silva, Augusto; Sanz, Mariano; Vernal Astudillo, Rolando (2009)
      Aim: T regulatory (Treg) cells have been detected in periodontitis lesions, and forkhead box P3 (Foxp3) expression has been negatively correlated to receptor activator of nuclear factor-κ B ligand (RANKL). The aim of this ...
    • Carvajal, Paola; Vernal Astudillo, Rolando; Reinero, Daniela; Malheiros, Zilson; Stewart, Bernal; Pannuti, Claudio Mendes; Romito, Giuseppe Alexandre (Sociedade Brasileira de Pesquisa Odontologica, 2020)
      The epidemiological data on gingivitis and periodontitis in Latin America are scarce, as the majority of the Latin American studies have analyzed probing depth instead of clinical attachment loss. Reported data have shown ...
