objective: an association between poor oral health and chronic lung disease has recently been reported. the purpose of this study was to explore this potential association between asthma and periodontal disease. materials and methods: this is a descriptive case controlled study. the samples were selected from patients referred to respiratory disease clinic in a hospital in tehran, iran. the stu...

Background. Polylactic-co-glycolic acid and zinc oxide (PLGA-ZnO) nanocomposite has been investigated for its antibacterial properties, which could be beneficial adding to wound dressings after periodontal surgery. However, cytotoxicity against human gingival fibroblasts (HGFs) remains unclear should evaluated. Methods. ZnO nanoparticles were synthesized using the hydrothermal method. These met...

BACKGROUND We investigated the physicochemical properties of Medifoam® N and its wound healing performance compared to other commercially available polyurethane (PU) foam dressing in vitro and in vivo to gain insight in their clinical performance. METHODS Wound contact layer and cross-section of eleven polyurethane foam dressings were assessed with field-emission scanning electron microscope....

BACKGROUND Despite a lack of evidence supporting their use, silver dressings are often used with negative pressure wound therapy (NPWT). This study investigates the effectiveness of silver dressings to reduce bacteria in contaminated wounds when used with NPWT. METHODS Complex orthopedic wounds were created on the proximal left legs of anesthetized goats. The wounds were inoculated with eithe...

Good hydration is the single most important external factor responsible for optimal wound healing. Unfortunately, available moisture retentive materials, products and devices require a certain expertise for application, are relatively expensive, may be associated with some serious complications and side effects, but most of all are impractical for application over large surface areas. We presen...

objective:  to assess whether non-surgical periodontal treatment is associated with changes in serological markers of systemic inflammation. materials and methods: thirty-five systemically healthy subjects with severe generalized periodontitis meeting the inclusion criteria participated in a four-month single blind interventional trial of which thirty-two completed the study. periodontal parame...
