background : this study investigated the in vitro and in vivo antibacterial effects of three mouthwashes on su-pragingival plaque microbiota. the three mouthwashes under study were 0.2% chlorhexidine (chx), listerine®, and persica (pm). water was used as negative control. methods : supragingival plaque samples were collected from 32 patients with gingivitis in the dental school of shahid behesh...

BACKGROUND The purpose of this study was to review the literature on the effects of a mouthrinse containing essential oils (EO) on plaque and parameters of gingival inflammation. METHODS The MEDLINE and Cochrane Central Register of Controlled Trials were searched up to and including December 2006 to identify appropriate studies. The primary outcome measure was gingivitis. Secondary parameters...

The purpose of the study was to assess the therapeutic effect of the angiogenesis inhibitor bevacizumab on plaques of various stages in rabbit models using contrast-enhanced ultrasonography (CEUS). Abdominal aortic atherosclerosis was induced in 55 rabbits. Thirty-six randomly selected rabbits were divided into 2 groups according to the timing of the bevacizumab injection: an early-stage plaque...

The aim of this study was to measure the effect of fluoride on the production of organic acids by Streptococcus mutans in dental plaque. The effect was studied in a simplified model of dental plaque with gnotobiotic rats monoinfected with S. mutans Ny341. Adaptation of S. mutans to fluoride was induced by feeding one group of the rats on fluoride-containing diet and drinking water. No differenc...

The potential of microbial mediated iron plaque reduction, and associated arsenic (As) mobility were examined by iron reducing bacteria enriched from As contaminated paddy soil. To our knowledge, this is the first time to report the impact of microbial iron plaque reduction on As mobility. Iron reduction occurred during the inoculation of iron reducing enrichment culture in the treatments with ...

Pre-softened, gauze-covered bovine enamel blocks were worn in the buccal sulcus of five subjects for seven days. Artificial plaque enmeshed in the gauze was treated four times per day for four days with an enzyme-dependent mineralizing solution, resulting in 20-, 10-, and 200-fold increases in Ca, P, and F, respectively. Enamel beneath this mineral-enriched plaque recovered 37% of the hardness ...

BACKGROUND MicroRNA are essential posttranscriptional modulators of gene expression implicated in various chronic diseases. Because microRNA-145 is highly expressed in vascular smooth muscle cells (VSMC) and regulates VSMC fate and plasticity, we hypothesized that it may be a novel regulator of atherosclerosis and plaque stability. METHODS AND RESULTS Apolipoprotein E knockout mice (ApoE(-/-)...

BACKGROUND Patients undergoing fixed orthodontic therapy may have difficulty in maintaining a good oral hygiene due to the difficulty posed by the appliances in accessing such areas. This study aimed to compare anti-plaque and anti-gingivitis efficacy of dentifrice containing Papain, Bromelain, Miswak and Neem with a standard dentifrice among patient's undergoing fixed orthodontic treatment. ...

Background: Anti-bacterial effect of Miswak on microorganism has already been proven in previous researches. The Dandasa is used by most women Saudi Arabia, India and Pakistan as a toothbrush for cleaning the teeth. Aim: This study was done comparison between improving gingival health, both anti-plaque action absence plaque directly proportional to health. Methods: A prospective cohort carried ...

Purpose: To explore effects of atorvastatin in combination with probucol on blood lipid and serum Creactive protein of patients with cerebral infarction. Methods: In total, 120 patients with confirmed cerebral infarction were randomly divided into test and control groups (n = 60 each). Control group was given atorvastatin 20 mg, once every night, while test group received 0.5 g probucol twice d...
