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...

BACKGROUND The study aimed to evaluating the effect of disinfecting impression materials on the dimensional accuracy and surface quality of the resulting casts. METHODS Impressions of a steel die constructed according to ANSI/ADA specification No.18 were made with each of alginate, addition cured silicone, condensation cured silicone and zinc oxide eugenol paste, and disinfected consequently ...

OBJECTIVE To compare the effect on prevalence of diarrhoea and mortality of household based treatment of drinking water with flocculant-disinfectant, sodium hypochlorite, and standard practices in areas with turbid water source in Africa. DESIGN Cluster randomised controlled trial over 20 weeks. SETTING Family compounds, each containing several houses, in rural western Kenya. PARTICIPANTS...

objective: previous studies have demonstrated that dental stone casts can be disinfected by replacing 10v% of required water with 5.25% sodium hypochlorite solution. this comparative study evaluated physical properties of dental stone models produced by replacing distilled water with sodium hypochlorite.   methods: in this in-vitro experimental study, a total of 45 dental stone models were prod...

1. Dakin's hypochlorite solution has the power of dissolving necrotic tissue, pus, and plasma clot in the concentration and reaction used clinically. 2. Chloramine-T and dichloramine-T do not exhibit this action. 3. The solvent action of Dakin's hypochlorite solution of the degree of alkalinity used clinically is due primarily to its hypochlorite content, but its slight alkalinity, while in its...

The aim of this study was to analyze fungal contamination on dental chairs at the clinic of a Higher Education Institution in TeresinaPI, Brazil, and to evaluate the effectiveness of different disinfectants: 70% alcohol and 1% sodium hypochlorite. We selected the five sites with most contact between patient and chair: headrest, backrest, armrests, seat and foot rest. Samples were collected from...

Concerns have been raised regarding handling of Ebola virus contaminated wastewater, as well as the adequacy of proposed disinfection approaches. In the current study, we investigate the inactivation of Ebola virus in sterilized domestic wastewater utilizing sodium hypochlorite addition and pH adjustment. No viral inactivation was observed in the one-hour tests without sodium hypochlorite addit...
