Current understanding of genetic polymorphisms as biomarkers for risk of biological complications in implantology
Background In the last decade, multiple studies have been published that analyze the relationship between the risk of experiencing biological complications with implants and the presence of certain types of genetic polymorphisms. In the present report, we analyze the controversies that have arisen from this important area of investigation and synthesize the most prominent aspects of knowledge related to this possible etiopathogenic relationship. Material and methods For this review, the biomedical databases PubMed-Medline, SciELO, and DOAJ were used. Different search strategies were employed, from which 298 articles initially emerged. After refinement of the search, 55 articles published be…
Salivary levels of Tumour Necrosis Factor-alpha in patients with recurrent aphthous stomatitis
Objetives: Recurrent aphthous stomatitis (RAS) is a common pathology of the oral mucosa with a complex and multifactorial etiology. Tumour Necrosis Factor-alpha (TNF?) is a cytokine with an important but not well-known role in the development of new lesions in RAS patients. Modifications of salivary levels of TNF? in RAS patients during the active periods of the disease have been measured in this work. The possible implication of TNF? in RAS etiology is also discussed. Study design: The study group was composed of 20 patients previously diagnosed with RAS and randomly selected. As a control group 10 healthy patients were also randomly selected. In both groups a TNF? assessment was carried o…
Candida albicans biofilms on different materials for manufacturing implant abutments and prostheses
[EN] Background: Morphological, physical and chemical properties of both implants and prostheses can determine the biofilm formation on their surface and increase the risk of biological complications. The aim of this study was to evaluate the capacity of biofilm formation of Candida albicans on different materials used to manufacture abutments and prostheses. Material and Methods: Biofilm formation was analyzed on cp grade II titanium, cobalt-chromium alloy and zirconia, silicone, acrylic resin (polymethylmethacrylate) and nano-hybrid composite. Some samples were partially covered with lithium disilicate glass ceramic to study specifically the junction areas. C. albicans was incubated in a …
