No full textUse of Probiotics for Oral Candidiasis: State of the Art and Perspective. A Further Step Toward Personalized Medicine?
No full textOral candidiasis is an opportunistic infection conventionally treated with antifungal drugs. However, the increasing number of fungal infections, parallel to the rising conditions sustained by non-albicans species, pose critical issues related to escalating drug resistances differently acquired by different species. Meanwhile, the knowledge of the interplay between oral microbiota and its host suggests alternative antifungal therapies based on the administration of probiotics. Probiotics are live microorganisms beneficial to the host, and literature reports consistent evidence for their use to treat gut diseases. The present work aimed to overview the primary mechanisms through which probiotics act against Candida species and the current status of knowledge on their use in clinical practice, particularly concerning oral candidiasis
Oral Mucosa Capillaroscopy: A Narrative Review
No full textThe oral cavity may suffer from diseases and lesions of different natures that can result in changes to the underlying microvasculature. These changes are typically observed during the examination of biopsy samples, but there is still a need to investigate methods for characterizing them in live tissues. Capillaroscopy, a medical imaging technique using polarized light and magnification, has shown promise in providing enhanced imaging of the oral mucosa microvasculature in preliminary studies. The present work proposed to review the literature on what capillaroscopy is, its applications in the imaging of oral mucosa microvasculature, and its diagnostic and prognostic significance in various diseases and conditions. While there is the limited literature available, further research in oral capillaroscopy, particularly in the field of oral oncology, is needed to determine its potential benefits in diagnosing and predicting outcomes for potentially malignant oral disorders and cancers

Biological response of human bone marrow mesenchymal stem cells to fluoride-modified titanium surfaces
No full textObjectives The aim of the present study was to examine the behaviour of human bone marrow-derived mesenchymal stem cells (BM-MSC) to fluoride-modified grit-blasted (F-TiO) titanium surfaces compared with grit-blasted ones (TiO). Material and methods Implant surfaces were analysed by atomic force microscopy (AFM) and scanning electron microscopy (SEM). BM-MSC were isolated from healthy donors and grown on the implant surfaces. Cell adhesion and proliferation, type I collagen (Col I) synthesis, osteoblastic differentiation (in terms of alkaline phosphatase activity, osteocalcin synthesis and extracellular matrix mineralization) were assessed. Furthermore, the ability to affect the osteoblastic/osteoclastic balance in terms of osteoprotegerin (OPG) and activator of nuclear factor kappa B ligand (RANKL) ratio was investigated. Results F-TiO surface showed higher S(a) values (P < 0.05) and the presence of nano-scale structures at the AFM and SEM analysis. Comparable cell morphology and similar adhesion values on both surfaces were detected at early time, whereas higher proliferation values on F-TiO samples were observed at 7 and 10 days. Increased Col I and OPG levels for cells grown on F-TiO were found, whereas RANKL was not detectable in any of the conditioned media. BM-MSC showed a similar expression of early and late osteogenic markers on both TiO and F-TiO surfaces. Conclusions The results of the present study show that the chemical and micro/nano-scale modifications induced by fluoride treatment of TiO-grit blasted surfaces stimulate the proliferation and the extracellular matrix synthesis by BM-MSC, as well as the increase of OPG synthesis, thus preventing osteoclast activation and differentiation.
