Treatment regimens, which predictably support re-osseointegration of implants with peri-implantitis, are needed. Increased wettability may be an important factor for re-osseointegration. In this study, a cold atmospheric pressure gas-discharge plasma was applied to reduce water contact angles on titanium discs different surface topography and improve the spreading osteoblastic cells.An argon jet oxygen admixtures used treat topologies, i.e. machined, SLA(®) , SLActive(®) diamond bur-treated...
To investigate the effects of a combined biofilm removal with an optimized air polishing and cold plasma device on cells in vitro.A 7-day-old was removed from rough titanium discs air-polishing erythritol powder (AP) or atmospheric pressure argon (CAP) combination both (AP + CAP). The efficacy evaluated by subsequent cell seeding osteoblast-like (MG-63). spreading analysed after 5 days incubation scanning electron microscopy. Separately, surface hydrophilicity measuring water contact angle...
Abstract The medical background of these investigations is periodontal disease which involves progressive loss the connective tissue and alveolar bone around teeth. Increased wettability dentin or replacement materials (hydroxyapatite) may be supportive for successful regeneration. In this in vitro study, we investigated if an atmospheric pressure, non‐thermal plasma process able to enhance hydroxyapatite as well increased translates into a higher spreading capacity osteoblasts. Surface...
In dentistry, zirconia has been used since the early 1990s for endodontic posts, more recently implant abutments and frameworks fixed dental prostheses. Zirconia is biocompatible mechanically strong enough to serve as material oral implants. Although several systems are available, currently scientific clinical data implants not sufficient recommend them routine use. Here influence of microstructured yttria-stabilized (YZ) on human primary osteoblast (HOB) behavior was determined. YZ surfaces...
Abstract The aim of this study was to investigate the feasibility an atmospheric pressure plasma jet (PJ) for endodontic treatment and compare antimicrobial efficiency with conventional irrigation solutions (chlorhexidine digluconate (CHX), sodium hypochlorite (NaOCl)) against intracanal bacteria (E. faecalis) using a standardized simulated root canal model. disinfection determined by number colony forming units. Scanning electron microscopy used effect procedures on inside canal. PJ...
Atmospheric pressure plasma‐jets could be an alternative method to remove bacterial biofilms on orthopaedic implants. Furthermore, plasma‐exposure might support the proliferation of osteoblasts after cleaning implants by activating implant surface. In this comparative in vitro study, efficacy five different plasma sources concerning removal and influence human osteoblast cell attachment was tested. Two revealed a significant reduction viability (>90%) enhanced spreading osteoblastic...
Tumor metastasis is associated with integrin-mediated adhesion and hyaluronan receptor expression. Accumulating evidence suggests that phytoestrogens, which are naturally occurring, plant-derived phytochemicals, could inhibit tumorigenesis during the development of breast cancer. Less known, however, about regulation receptors by phytoestrogens and, particularly, their potency to influence proliferation primary human cells in comparison steroid hormone 17β-estradiol. Throughout experiments,...
The aim of this study was to compare the effect atmospheric pressure plasma (APP) with sodium hypochlorite (NaOCl) or combination APP and NaOCl on Enterococcus faecalis biofilm in root canals extracted human teeth. disinfection efficiency determined as logarithm number colony-forming units (CFU). Additionally, scanning electron microscopy (SEM) used visualize treatment biofilm. adjunctive Plasma + O2 has a small additive, albeit statistically not significant CFU reduction an E. compared 12...
The initial adhesion and spreading of cells are crucial factors for the successful performance a synthetic biomaterial used cell culture disposables or human medical devices (e.g., implants). Surface properties which allow control attachment decisive acceptance provided material. Hence, different surface preparation techniques to equip surfaces with functional groups improve interactions. In this paper, polystyrene (PS) were modified by using nonthermal plasma processes. particular,...
Background/Objectives: Extensive and closely coordinated remodeling processes take place in the periodontal ligament (PDL) adjacent bone during orthodontic tooth movement. In complex cases, it is necessary to move teeth into an augmented bony defect, for example, patients with cleft lip, alveolus, palate. The important role of PDL movement well accepted but not fully understood. Therefore, present study investigated after 23 weeks critical-sized defect. Methods: second molars four beagle...
Depending on their composition, plastics have a cytotoxic potential that needs to be evaluated before they are used in dentistry, e.g., as orthodontic removable appliances. Relevant guidelines set out requirements new resin the medical field must meet, with wide scope for experimental design. In present study, test specimens of different geometries consisting varying polymers (Orthocryl®, Orthocryl® LC, Loctite® EA 9483, Polypropylene) were soaked periods time, then transferred cell culture...
