Studies aimed at increasing the efficacy of chemotherapeutic drugs and reducing or completely eliminating their side effects are frequently encountered. In our study, we considered methotrexate (MTX), which is in category anticarcinogenic anti-inflammatory drugs, gemcitabine (GEM), used treatment breast, testicular, ovarian, etc. cancers. GEM, cancers, was covalently bonded to maleic anhydride vinyl acetate (MAVA) copolymer, new polymer–drug conjugates (MAVA–MTX MAVA–GEM) were obtained...

Abstract Aim To evaluate the number of bacteria extruded apically from extracted teeth ex vivo after canal instrumentation using two engine‐driven techniques utilizing nickel‐titanium instruments (ProTaper and System GT). Methodology Forty single‐rooted human mandibular premolar were used. Access cavities prepared root canals then contaminated with a suspension Enterococcus faecalis dried. The roots divided into experimental groups 15 each one control group 10 teeth. Group 1, ProTaper group:...

To evaluate the number of bacteria extruded apically from extracted teeth ex vivo after canal instrumentation using a manual technique and three engine-driven techniques utilizing nickel-titanium instruments (K3, RaCe, FlexMaster).Seventy human mandibular premolar with similar dimensions were used. Access cavities prepared root canals then contaminated suspension Enterococcus faecalis dried. The roots divided into four experimental groups 15 each one control group 10 teeth. G1. RaCe group:...

In endodontics, the elimination of resistant bacteria such as Enterococcus faecalis plays an important role for treatment success in root canals. Therefore, new alternative irrigants (instead sodium hypochlorite) have been researched to achieve ideal endodontic treatment.The aim present study was evaluate and compare antibacterial effect aqueous ozone with different concentrations techniques application (manual ultrasonic) against E. human canals.Eighty single-root mandibular premolar teeth...

The aim of this study was to appraise the some mechanical properties polymethyl methacrylate based denture base resin polymerized by copolymerization mechanism, and investigate cytotoxic effect these copolymer resins.MATERIALS AND METHODS.2-hydroxyethyl (HEMA) isobutyl (IBMA) were added monomers conventional heat injection-molded poly methyl (PMMA) contents 2%, 3%, 5% volume polymerization carried out.Three-point bending test performed detect flexural strength elasticity modulus resins.To...

To evaluate the antibacterial activity of gaseous ozone and chlorhexidine solution on a tooth cavity model.Twenty-one human molars were divided into 3 groups. Cavities then cut teeth (4 per tooth, 28 cavities group). After sterilization, left in broth cultures 106 colony-forming units (CFU) ml-1 Streptococcus mutans (S. mutans) at 36°C for 48 h. The appropriate treatment followed (group A, control; group B, 2% solution; C, 80s with ozone, filled composite resin. 72h, restorations removed,...

The success of endodontic treatment depends on a few crucial factors. One these factors is the complete chemomechanic preparation root canal against various bacteria. In particular, effect resistant bacteria may cause intense pain with flare-up and formation periapical lesions. Therefore, strong irrigants plays an important role in terms elimination to achieve long-term successful treatment.The aim this study was investigate antibacterial effects super-oxidized water (SPO) canals infected...

The purpose of this study was to investigate the antibacterial effects two different types laser and aqueous ozone in human root canals infected by Enterococcus faecalis.Many techniques have been developed find an alternative sodium hypochlorite as a disinfection agent for canals. However, no has evaluated exactly same antimicrobial with (NaOCl).Eighty mandibular premolar teeth single roots were selected. Following canal preparation irrigation, sterilization performed autoclave. E. faecalis...

This study evaluates the in vitro potency, stability and contamination of fortified ophthalmic antibiotic preparations cefazolin, vancomycin, gentamicin tobramycin stored for 4 weeks. The effects different solvents storage temperatures on antimicrobial potency were also examined.The stock solution cefazolin vancomycin prepared by reconstituting with 0.9% sodium chloride artificial tears. Gentamicin adding parenteral forms into their commercial solutions. was measured minimum bactericidal...

Several all-ceramic materials have been developed to meet the most challenging requirements in restorative dentistry. However, only limited reports focused on issue of biocompatibility all-ceramics. The purpose this study was evaluate effects different types substructural determine their biological performance under experimental conditions. We tested six systems [glass-infiltrated alumina-reinforced ceramic (In-Ceram Alumina, Turkom Cera), glass-infiltrated zirconia-toughened alumina...

To evaluate the bacterial extrusion during instrumentation with different nickel titanium (NiTi) engine-driven instruments.Ninety extracted single-canal human mandibular incisor teeth were inoculated Enterococcus faecalis to obtain biofilm formation and randomly divided 6 groups (n=15). One group served as control was not instrumented; other prepared ProTaper Gold (PTG; Dentsply Maillefer, Ballaigues, Switzerland), WaveOne (WOG; Maillefer), Twisted File Adaptive (TFA; SybronEndo, Orange, CA,...
