in the present study 220 diarrheal samples of children aged between 3-12 months and 100 samples from healthy individuals of the same age group reffered to Shiraz university hospitals were investigated for bacterial and viral agents.Electron microscopy methods were used for the viral investigations,while conventional techniques of bacteriology were used for isolation of bacterial agents.the prev...

objective: this study investigated the antibacterial properties of an ion-releasing resin composite (degufill), a hybrid resin composite (inten-s), a compomer (compoglass f) and a resin-modified glass ionomer (vitremer) against streptococcus mutans. materials and methods: the bacteria were derived from the dental plaque and cultured on blood agar plates. eppendorf tubes were filled by unset res...

background and aims. triple antibiotic paste (tap) is widely used in endodontics for root canal disinfection, particularly in regenerative procedures. the aim of this in vitro study was to evaluate the antimicrobial effects of different concentrations of tap at 1-, 2-, 3-, and 4-week intervals on mature enterococcus faecalis biofilm. materials and methods. a total of 287 extracted one-rooted hu...

backgrounds: different susceptibility rates of pathogenic bacteria to antimicrobial agents are considered major factors in the choice of drugs and the success of treatments. concerns have been raised regarding the emergence of antimicrobial resistance among pathogenic bacteria that may result in unpredictable antimicrobial susceptibilities and therapy failure. objectives: the purpose of this in...
