Raw seed sprouts have caused numerous outbreaks of enteric infections. Presoaking seeds in a 20,000 mg/liter (ppm) calcium hypochlorite solution before sprouting is recommended to reduce bacterial contamination and infection risk. In 1999, the authors investigated an outbreak of Salmonella serotype Typhimurium infections in Colorado. In a case-control study, they matched 20 cases with 58 contro...

Endodontic irrigating solutions may have different effects, one of which is dissolving pulp tissue. The capacity of different irrigants to dissolve vital and necrotic pulp tissue was evaluated in vitro by means of a quantitative and qualitative study of total soluble pulp protein. Vital pulps and pulps with induced necrosis from young bovine teeth were used. Pulp was cut into smaller pieces, we...

The purpose of this study was to test a gallium nitrate solution, a resorption inhibitor, employed as a root canal dressing in teeth submitted to late replantation. Thirty maxillary right central incisors of rats were avulsed and kept dry for thirty minutes. The teeth were instrumented and the root surfaces were treated with 1% hypochlorite solution followed by application of 2% sodium fluoride...

Poultry Litter Necrotic enteritis and the subclinical form of Clostridium perfringens infection in poultry are caused by C. perfringens type A, producing the alpha toxin, and to a lesser extent type C, producing both alpha toxin and beta toxin C and have become serious threats to poultry health.This study was undertaken to determine the activity of 4 commonly available disinfectants against C. ...

Root canal irrigants play a significant role in elimination of the microorganisms, tissue remnants, and removal of the debris and smear layer. No single solution is able to fulfill all these actions completely; therefore, a combination of irrigants may be required. The aim of this investigation was to review the agonistic and antagonistic interactions between chlorhexidine (CHX) and other irrig...

OBJECTIVE To identify the contents of ampoules stored items at the WW I Kobarid Museum, Slovenia. Sources and methods: Analysis of ampoules from the Kobarid Museum using pharmacopoeial methods. RESULTS The contents of the unlabelled ampoules were identified as calcium hypochlorite, a decontaminant for mustard gas (Yperite). CONCLUSION The Isonzo front/Soška fronta was opened on May 24 1915 ...

A number of treatments have been devised to improve the appearance of fluorosed enamel. However, many of these have been empirically based, and the success of the various treatment regimens have not been quantitated. In this study, the relative whiteness of normal, mildly fluorosed, moderately fluorosed, and carious white-spot lesions on extracted teeth was quantitated by light reflectance usin...

i ntroduction: the aim of the present study was to evaluate whether adding 2% chlorhexidine (chx) and 2.6% sodium hypochlorite (naocl) to calcium-enriched mixture (cem) cement would affect its setting time (st), or not. methods and materials: in this study, the setting time of cem cement was evaluated in three groups ( n =9) as follows: group 1; cem cement, group 2; cem cement+2% chx and group ...
