Dental implants in dental agenesis are an effective and sustainable solution for replacing missing teeth patients who have not developed some or more permanently. is a condition which one do form erupt normally. In the case of agenesis, can be used to replace teeth, giving patient aesthetic smile necessary functionality during chewing speaking. Here important discussions about agency: Individual evaluation: Each with will evaluated individually by dentist. Issues such as number position bone...
CBCT (Cone Beam Computed Tomography) plays a crucial role in implantology, offering significant advantages over traditional two-dimensional imaging techniques, such as X-rays. Here are some of the important benefits implantology. Precise three-dimensional imaging: provides high-resolution images patient's oral and maxillofacial region. This allows comprehensive assessment anatomical structures, including bone volume, quality, density. evaluation these factors is for successful implant...

Medical research explores plant extracts' properties obtain potential nanomaterial-based anticancer The present study aims formulate, develop, characterize mucoadhesive films loaded Usnea barbata (L.) dry acetone extract (F-UBA) investigate their for possible use in cancer therapy. U. (UBA) was solubilized ethanol: isopropanol...
Lichens represent a significant source of antioxidants due to numerous metabolites that can reduce free radicals.
This study aims to complete our research on Usnea barbata (L.) Weber ex F.H. Wigg (U. barbata) from the Călimani Mountains, Romania, with an elemental analysis and explore its antibacterial antifungal potential. Thus, we analyzed twenty-three metals (Ca, Fe, Mg, Mn, Zn, Al, Ag, Ba, Co, Cr, Cu, Li, Ni, Tl, V, Mo, Pd, Pt, Sb, As, Pb, Cd, Hg) in dried U. lichen (dUB) by inductively coupled plasma mass spectrometry (ICP-MS). For second study, performed extraction five different solvents (ethyl...
Usnea lichens are known for their beneficial pharmacological effects with potential applications in oral medicine. This study aims to investigate the extract of barbata (L.) Weber ex F.H. Wigg from Călimani Mountains canola oil as an pharmaceutical formulation. In present work, bioadhesive films (F-UBO) U. (UBO) were formulated, characterized, and evaluated, evidencing potential. The UBO-loaded analyzed using standard methods regarding physicochemical pharmacotechnical characteristics verify...
The secondary metabolites of lichens have proven to be promising sources anticancer drugs; one the most important these is usnic acid, which a phenolic compound with dibenzofuran structure that responsible for numerous biological actions genus Usnea. As result, in this study, we related metabolite. aim present study evaluation cytotoxic activity Usnea barbata (L.) F. H. Wigg dry acetone extract (UBE).
