Background and purpose: From many years ago denture adhesives have been used to improve denture’s performance. During the time, many new formulations have been prepared and evaluated to improve the properties of this product. In this study, the powder form of this product was prepared then in vitro and in vivo evaluations were performed. Material and Methods: To design the denture adhesive pow...
background and aims: recurrent aphthous stomatitis (ras) is one of the most common ulcerative diseases of the oral mucosa. definitive etiology of ras has not been conclusively established. there is no certain treatment for aphthous but some drugs such as steroid are commonly used for treatment of ras. regarding the effect of zinc on healing process of epithelial layer and cell division, in this...
keratocystic odontogenic tumor (kcot) is a benign intraosseous neoplasm of the jaw occurring most commonly in mandibular ramus molar area with male predilection. peripheral kcots are very uncommon. here we report a case of keratocyst in buccal mucosa in a 55 years old female patient, the diagnosis of which was based on subjective histological evaluation and further confirmed by immunohistochemi...
Introduction: With increased usage of restorative materials, dentists are more concerned in choosing a suitable material with lower adhesion of pathogens like streptococci. This comparative in vitro study aimed to compare adhesion of streptococcus mutans to zirconia, IPS Empress II, noble alloy, and base-metal. Materials and Methods: In this descriptive study, 50 specimens (5 mm diameter disk ...
The aim of the study was to examine a perfusion and integrity of small bowel in 60 subsequent patients during the major open abdominal surgery which lasted from 2 to 7 hours. Two samples of the intestinal mucosa were removed: at the beginning, and at the end of the surgical procedure in general anaesthesia. A mucosal injury was classified into 4 grades. pH, PCO2 and lactate level were measured ...
Leishmania spp. are intracellular parasites that cause lesions in the skin, mucosa, and viscera. We have previously shown that Leishmania infection reduces mononuclear phagocyte adhesion to inflamed connective tissue. In this study, we examined the role of adhesion molecules and chemokines in this process. Infection rate (r = -0.826, P = 0.003) and parasite burden (r = -0.917, P = 0.028) negati...
