The purpose of this study was to investigate the in vitro effect of two irrigation solutions used in endodontics (5.25% sodium hypochlorite and 1% glutaraldehyde) on substrate adherence capacity of macrophages to determine if these substances can alter macrophage function. Inflammatory macrophages were obtained from Wistar rats and resuspended in RPMI-1640 medium. Substrate adherence capacity a...

The purpose of this study was to examine the biofilm removing and antimicrobial effects of microbubbled tap water and other functional water. The biofilm removal test showed that the activity of microbubbled tap water against the biofilm of Candida albicans and Streptococcus mutans was significantly higher than that of ordinary tap water (p<0.01). When the antimicrobial activities of two types ...

BACKGROUND AND OBJECTIVES Smear layer removal with EDTA from root canal walls allows greater cleaning and disinfection of root canals. However, because Er:YAG laser acts on the removal of the smear layer, the objective of investigation was to analyze in vitro the effect of Er:YAG laser on dentin root canal wall permeability after endodontic instrumentation and irrigation with water or sodium hy...

Combined disinfection with UV radiation and sodium hypochlorite was applied in disinfection the effluent after secondary treatment of hospital sewage. The inactivation effect of different combination modes and sequences of UV and sodium hypochlorite was studied. The contrast experiments of disinfection effect and the levels of residual chlorine were conducted by adding different dosage of sodiu...

The present study evaluated the influence of 2% chlorhexidine and 2.5% sodium hypochlorite on the resin sealer/dentin interface bond strength of AH Plus/gutta-percha and Epiphany/Resilon. Seventy-two extracted bovine incisors were randomly distributed into 6 groups according to irrigant and sealers: G(S+AH)=physiologic saline solution+AH Plus/gutta-percha; G(S+Ep)=physiologic saline solution+Ep...

Endodontic emergencies are associated with pain and swelling which requires immediate diagnosis and treatment. The main causative factors for these emergencies are pulp and peri-radicular pathosis, traumatic injuries, procedural complications; were sodium hypochlorite accidents can occur. The impetus behind a successful root canal treatment relies on a thorough debridement of tissue remnants, b...

Ó Abstract: Background: With the looming global HIV pandemic, the problem of tuberculosis tiptoes as a perpetual companion. Smear negative pulmonary tuberculosis which pose substantially a challenge for diagnosis, hoots this combination into noxious health problem. There is, therefore, an urgent need to establish more sensitive, safe and fairly rapid methodologies that could confirm diagnosis p...

OBJECTIVE The aim of this human in vivo pilot study was to evaluate the efficacy of six antimicrobial agents on the surface decontamination of an oral biofilm attached to titanium implants. DESIGN For in vivo biofilm formation, we fixed titanium specimens to individual removable acrylic upper jaw splints (14 specimens in every splint), which were worn by four volunteers overnight for 12 h. Th...

V arious forms of chlorine are commonly used in drinking water and water reuse applications for their ability to disinfect and maintain a residual level of disinfectant throughout the distribution system. The majority of utilities in the United States use chlorine gas during treatment, but approximately one third of all US drinking water treatment plants use bulk hypochlorite for disinfection, ...

Household point-of-use (POU) water treatment technologies targeted at vulnerable populations are microbiologically effective and, in small trials, improve health. We do not understand the factors that influence preference for and adoption of these technologies by target end-users. We cycled 400 rural subsistence farm households in western Kenya through three randomly ordered two-month trials of...
