Subgingival Irrigation with a Solution of 20% Propolis Extract as an Adjunct to Non-Surgical Periodontal Treatment: A Preliminary Study.

Natural products, including propolis, are now frequently used to treat periodontal disease, but there are a few clinical studies in this area. The aim of this randomized clinical trial was to evaluate the effect of subgingival irrigation of periodontal pockets with a hydroalcoholic solution of propolis extract 20% (w/v) as an adjunct to periodontal therapy. Sixteen individuals were divided into a test group (TG), comprised 65 teeth (scaling and root planing + irrigation with propolis solution), and a control group (CG), comprised 62 teeth (scaling and root planing + irrigation with saline solution).

High doses of alcohol during pregnancy cause DNA damages in osteoblasts of newborns rats.

Background: Alcohol exerts teratogenic effects and its consumption during pregnancy can cause deficit of bone development. The aim of the current study was to evaluate the genotoxic effects of prenatal exposure to ethanol on newborn rat osteoblasts.

Methods: Wistar rats were initially divided into two groups: Ethanol group which received Ethanol 20% V/V in liquid diet and solid diet ad libitum, and Control group, which received solid diet and water ad libitum.

Porous titanium and Ti-35Nb alloy: effects on gene expression of osteoblastic cells derived from human alveolar bone.

Tests on titanium alloys that possess low elastic modulus, corrosion resistance and minimal potential toxicity are ongoing. This study aimed to evaluate the behavior of human osteoblastic cells cultured on dense and porous Titanium (Ti) samples comparing to dense and porous Ti-35 Niobium (Ti-35Nb) samples, using gene expression analysis. Scanning electronic microscopy confirmed surface porosity and pore interconnectivity and X-ray diffraction showed titanium beta-phase stabilization in Ti-35Nb alloy.

Titanium-35niobium alloy as a potential material for biomedical implants: In vitro study.

Research on new titanium alloys and different surface topographies aims to improve osseointegration. The objective of this study is to analyze the behavior of osteogenic cells cultivated on porous and dense samples of titanium-niobium alloys, and to compare them with the behavior of such type of cells on commercial pure titanium. Samples prepared using powder metallurgy were characterized using scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), and metallographic and profilometer analyses.
