BACKGROUND Continuous positive airway pressure (CPAP) with nasal devices (nCPAP) is widely used in the respiratory management of newborns. The present study aimed to compare the incidence of nasal trauma secondary to nasal continuous positive airway pressure (nCPAP) protected with or without hydrocolloid dressing in preterm infants. METHODS This prospective controlled study was performed in t...

BACKGROUND Bubbles and voids on the occlusal surface impede the actual intercuspation and pre-impression preparation aims to reduce the incidence of air bubbles and voids as well as influences the quality of occlusal reproduction and actual clinical intercuspation in the articulator. The study was undertaken to determine the influence of different pre-impression preparation procedures of antago...

A meta-analysis of published research enabled dressing efficacy to be estimated. Comparisons showed greater efficacy of hydrocolloid dressings but failed to confirm advantages of other advanced dressings compared with conventional ones.

objective: the aim of this study was to evaluate the dimensional stability of casts made from an alginate impression material poured immediately and stored after specific periods. materials and methods: the common alginate used in iran (super; iralgin, golchai co., tehran, iran) was tested. a master model was mounted on a special device and used to obtain the impressions. these impressions were...

The purpose of this study was to investigate the influence of different hydrophilic polymers on the swelling, bioadhesion and mechanical strength of hydrocolloid wound dressings (HCDs) in order to provide an appropriate composition for a hydrocolloid wound dressing system. In this study, the HCDs were prepared with styrene-isoprene-styrene copolymer (SIS) and polyisobutylene (PIB) as the base u...

In this work attempts were made to evaluate K+-SDS and hydrocolloid polymer-SDS interactions in flocculation of megestrol acetate dispersions to enhance their stability as a part of suspension formulation. Different dispersions of micronized megestrol acetate and SDS were prepared. KCl and KH2PO4 and their corresponding sodium salts were added to the dispersions and the preparations were evalua...

BACKGROUND Most of the materials (casts, impressions, etc.) that are sent to the dental laboratories show the presence of numerous pathogenic microorganisms. All the spray disinfectants are not equally effective against these microorganisms. AIMS AND OBJECTIVES The aim was to compare the effectiveness of different spray disinfectants on irreversible hydrocolloid impressions and to find out th...

BACKGROUND Hydrocolloid technology has been proven effective in treating dermal wounds. A previous study showed that a newly developed thin hydrocolloid patch [Compeed cold sore patch (CSP)] provided multiple wound-healing benefits across all stages of a herpes simplex labialis (HSL) outbreak. METHODS An assessment of CSP efficacy and safety was conducted in an international, multicentre, ass...

background: addition of disinfectant to irreversible hydrocolloid impression materials can eliminate the disinfection step to avoid dimensional changes associated with it. the aim of the present study was to evaluate the effect of various disinfectant mixing liquids on the properties of commercially available irreversible hydrocolloid impression materials. materials and methods: four commercial...
