background : incidence of  white  spots due  to  demineralization of  enamel  and  gingival problems  is  an  unacceptable  result  of  orthodontic  treatment.  plaque  accumulation  and bacterial biofilm growth are responsible for these phenomena. the resin-based dental composites used as bonding agents in orthodontics play a major role in mentioned problems. as recent researches assert the an...

Bone implants must be biocompatible and are usually built to promote osseointegration, e.g. by application of plasma spray calcium phosphate (CaP) coating. The risk of infection and biofilm formation on implant surfaces is a well-known problem. The combination of electrochemically deposited CaP coating with antibiotics may offer significant benefits. Here, we demonstrate an innovative in situ e...

The main clinical problems for dental implants are (1) formation of biofilm around the implant-a condition known as peri-implantitis and (2) inadequate bone formation around the implant-lack of osseointegration. Therefore, developing an implant to overcome these problems is of significant interest to the dental community. Chitosan has been reported to have good biocompatibility and anti-bacteri...

BACKGROUND Pathogenic bacteria are able to develop various strategies to counteract the bactericidal action of antibiotics. Silver nanoparticles (AgNPs) have emerged as a potential alternative to conventional antibiotics because of their potent antimicrobial properties. The purpose of this study was to synthesize chitosan-stabilized AgNPs (CS-AgNPs) and test for their cytotoxic, genotoxic, macr...

BACKGROUND Long term successful root canal treatment requires effective debridement and disinfection of root canal system. Persistent periradicular lesions are usually associated with Enterococccus faecalis. Prompt research for natural alternatives for irrigation is mainly due to the constant increase in antibiotic resistant strains and side effects caused by synthetic drugs. Sodium hypochlorit...

This study investigated the efficacy of co-deposited vancomycin/chitosan coatings prepared using a plasma process on metallic implants in bacterially challenged rabbit model. A BioDepTM coating was used to deposit thin layers chitosan with vancomycin onto titanium alloy surfaces. Coated were examined standard microscopy, profilometry and elution studies. Nitrided Ti-6Al-4V (Ti alloy) dynamic co...

In a drinking water distribution system, biofilm-producing bacteria are considered an alarm bell for increased emergence of waterborne pathogens. This study aims to monitor the prevalence biofilm-forming Aeromonas species in systems different broiler chicken farms. The antimicrobial activity thyme essential oil (TEO), nano-emulsion (TEO-N), chitosan (CS), nanoparticles (CS-NPs), and both CS CS-...
