“…Average roughness (Ra) and maximum height of the profile (Rt) ( n = 5) were assessed by profilometry (Dektak D150; Veeco, Plainview, NY, USA) 9 . Ti ion release from the substrate ( n = 3) was measured by inductively coupled plasma optical emission spectrometer (ICP‐OES, iCAP model, 7000 series; Thermo Scientific, MA, USA) 20 . For rubbing groups, samples were quickly rinsed with the remained solution after treatment and cotton swabs were vortexed for 30 s in treatment solutions to stimulate dissociation of impregnated ions.…”

Objective The present study aimed to establish an optimized protocol for biofilm removal from titanium (Ti) surfaces using citric acid (CA) solutions. Background Biofilm accumulation is the main factor to trigger peri‐implant infections and to increase the risk of treatment failures. Although CA has been suggested as the anti‐infective agent with highest potential for biofilm removal on Ti, there is no consensus that CA could improve the anti‐infective treatment and its effect. Methods Physical and chemical alterations, electrochemical behavior, cytotoxicity, and antimicrobial effect of CA on Ti discs were evaluated using four concentrations (1, 10, 20, and 40%) and two application methods (immersion and rubbing). Negative control using 0.9% NaCl was used in all experiments. To evaluate whether different application times can have similar response, polymicrobial biofilm (microcosm model) was formed on Ti and treated with CA for 1, 2, 4, and 8 min. An in situ study was conducted to verify whether the established protocol is equally effective in biofilms formed on machined and sandblasted, large‐grit, and acid‐etched (SLA) Ti surfaces. Results CA 40% induced significantly higher surface alterations observed by confocal images and profilometry. In general, rubbing protocol decreased the surface roughness and increased the wettability (p < 0.05), exhibiting better surface cleaning by biofilm removal. CA 10% presented no indirect cytotoxicity and, when applied by rubbing for 8 min, presented proper in vitro antibacterial action and potential corrosion inhibition. When CA 10% was rubbed on Ti surfaces for 4 min, it displayed optimum cleaning ability as 8 min, working equally to remove in situ biofilm on machined and SLA surfaces. Conclusions The application of CA 10% by rubbing for at least 4 min demonstrated to be a promising protocol to eliminate biofilms formed in smooth and rougher surfaces, which could improve implant‐related infection therapies.

“…PEO-BG modulates the oral biofilm, favoring the colonization of beneficial microorganisms and reduces the pathogenic potential of the biofilm surrounding the implant. In addition, PEO-BG coatings show prolonged ion release and pH variations, leading to faster hydroxyapatite formation capacity and increased protein adsorption from blood plasma without cytotoxic effects on fibroblast cells in human gingival tissue, thus allowing the osseointegration process to take place [200].…”

Diseases or complications that are caused by bone tissue damage affect millions of patients every year. Orthopedic and dental implants have become important treatment options for replacing and repairing missing or damaged parts of bones and teeth. In order to use a material in the manufacture of implants, the material must meet several requirements, such as mechanical stability, elasticity, biocompatibility, hydrophilicity, corrosion resistance, and non-toxicity. In the 1970s, a biocompatible glassy material called bioactive glass was discovered. At a later time, several glass materials with similar properties were developed. This material has a big potential to be used in formulating medical devices, but its fragility is an important disadvantage. The use of bioactive glasses in the form of coatings on metal substrates allows the combination of the mechanical hardness of the metal and the biocompatibility of the bioactive glass. In this review, an extensive study of the literature was conducted regarding the preparation methods of bioactive glass and the different techniques of coating on various substrates, such as stainless steel, titanium, and their alloys. Furthermore, the main doping agents that can be used to impart special properties to the bioactive glass coatings are described.

Bioactive glass (BG) and glass-ceramics (GC) have been employed for bone treatment tissue engineering applications. Bioactive glasses/bioglasses can be considered promising materials for bone-regenerative scaffolds fabrication, owing to the adaptable properties that make them appropriately be designed regarding their composition. The essential properties of bioactive glasses, enabling them to be applied in the engineering of bone tissue, can be explained as their potential to augment differentiation osteoprogenitor and cells of mesenchymal stem cells, enzyme activity, osteoblast adhesion, and revascularization. Much research is conducted for the development of phosphate glasses, borate/borosilicate BGs, and silicate. Accordingly, some metal-based glasses have also been surveyed for tissue engineering uses, technologically and biomedically. Many rare elements can also be incorporated in the network of the glass to achieve promising properties, possessing a positive influence on the associated angiogenesis and/or remodeling of bone. This review motivates for providing an overview toward bioactive glasses' general requirements, composition, production, and impact of ion substitution on bioactive glass. Attention has also been given to developments of bioactive glass applications in bone grafting, bone regeneration, drug delivery, dental implant coatings, antibacterial agents, and soft tissue engineering as well as challenges and future perspectives.
