Static headspace gas chromatographic (SHS-GC) analysis was performed to determine the release of 13 odorants in hydrocolloid model systems containing original or regio-selectively carboxylated cellulose at different pH values. The release of most odor compounds was decreased in the hydrocolloid solutions compared to control, with the amounts of 2-propanol, 3-methyl-1-butanol, and 2,3-butanedion...

Four different hydrocolloids, carageenan, carboxymethyl cellulose, guar gum and xanthan were administered at four different levels of substitution, 0.25, 0.5, 0.75 and 1.0% to 7.0% (w/w) fennel fortified bread to study the effects of hydrocolloids as texture improver. Physical properties like loaf weight were mostly unchanged while addition of hydrocolloid seems to have a positive effect on loa...

Objective: To compare hydrocolloid with conventional gauze dressing in prevention of infections after clean surgical procedures. Study Design: Randomized controlled trial. Place and Duration of Study: Department of Surgery, CMH Rawalpindi from 22 Jan 2010 to 22 Aug 2010. Patients and Methods: A total of 400 patients undergoing clean surgical procedures were randomly allocated in two equal group...

AIM Relating the marginal fit of the castings, to the accuracy of the impression produced using laminated hydrocolloid impression technique, alginate and double-mixed polyvinyl siloxane. Basic objective of the study is to check the feasibility of the use of laminated hydrocolloid impression technique in the fixed partial denture. MATERIALS AND METHODS The precisely machined metal die was desi...

OBJECTIVE Pressure Ulcers (PUs) often is an indication of quality of nursing care as it remains as severe manifestation of the integrity of impaired skin. Our study designed to evaluate the effectiveness of hydrocolloid dressings and ceramide dressings in healing of PU. PATIENTS AND METHODS The study was done at Chinese hospital between Feb 2014-November 2014. 72 study group patients and 25 c...

The aim of this research was to investigate the influence of hydrocolloid pre-treatment, i.e. pectin, carboxymethyl cellulose (CMC), gum arabic and sodium alginate on the quality of vacuum fried jackfruit (JF) chips. The control JF samples (no hydrocolloid treatment) showed higher absorption of oil whereas the oil absorption was less in the hydrocolloid pre-treated samples. The retention of moi...

AIM Dental impressions are potential sources of bacterial contamination which could eventually lead to transmissible infectious diseases through the blood or saliva. Sodium hypochlorite is an effective disinfectant recommended by the American Dental Association (ADA) in a 1:10 dilution for a ten minute immersion to disinfect irreversible hydrocolloid impressions. As the ADA protocol is sometime...

Seventy patients with 90 venous ulcers were randomly assigned to hydrocolloid or conventional dressing and compression therapy at four study centers. The ulcers had been present for a mean of 47.8 in the control and 46.2 weeks in the treatment group and 42% of all patients had recurrent ulcers. Ulcers treated with hydrocolloid dressings reduced 71% and control treated wounds reduced 43% in area...

The disinfection of dental impression materials has become an essential topic of universal concern, as it may be the first instance of microbial contamination during dental care. The purpose of this study is twofold: To determine the effectiveness of disinfection with 0.5% sodium hypochlorite and 2% glutaraldehyde solutions in irreversible hydrocolloid (alginate) and silicone impressions and to...

OBJECTIVE To study the efficacy of electrolyzed oxidizing water (EOW) and hydrocolloid occlusive dressings in the acceleration of epithelialization in excised burn-wounds in rats. METHODS Each of the anesthetized Sprague-Dawley rats (n=28) was subjected to a third-degree burn that covered approximately 10% of the total body surface area. Rats were assigned into four groups: Group I (no irriga...
