Streptococcus mutans contributes significantly to dental caries, which arises from homoeostasic imbalance between host and microbiota. We hypothesized that Lactobacillus sp. inhibits growth, biofilm formation and gene expression of Streptococcus mutans. Antibacterial (agar diffusion method) and antibiofilm (crystal violet assay) characteristics of probiotic Lactobacillus sp. against Streptococc...

OBJECTIVES Recurrent caries was partly ascribed to lack of antibacterial properties in composite resin. Silver and zinc nanoparticles are considered to be broad-spectrum antibacterial agents. The aim of the present study was to evaluate the antibacterial properties of composite resins containing 1% silver and zinc-oxide nanoparticles on Streptococcus mutans and Lactobacillus. MATERIALS AND ME...

asthma is a chronic inflammatory disorder of the airways, which is diagnosed by periodic symptoms of inflammation, bronchial spasm, and increased mucosal secretions. it has higher incidence among the preschool children. there are many contradictory reports based on the effect of asthma on oral health, however it has been hypothesized that asthma could lead to poor oral health. the objective of ...

Dental caries is the result of bacterial metabolic activity in dental biofilm with bacterium Streptococcus mutans, identified as primary etiological factor for and Lactobacillus plays an important role progression disease. The purpose study was to evaluate level cariogenic bacteria, S. mutans 30 children their respective mothers. Children affected had high levels relation free (60% 20% respecti...

background: most of the population in the different areas of world is affected by bacterial infections responsible for dental caries. due to the importance of traditional medicines derived from herbs used for dental problems, this study investigated in vitro antibacterial activity of mentha longifolia essential oil from ardabil, iran, on streptococcus mutans, lactobacillus rhamnosus and actinom...

BACKGROUND The majority of caries lesions in adults occur on the proximal tooth surfaces of the posterior teeth. A comprehensive study of the composition of the oral microbiota is fundamental for a better understanding of the etiology of interdental caries. METHODS Twenty-five caries-free subjects (20-35 years old) were enrolled in the study. The interdental biofilm of four interdental sites ...

Bakuchiol was isolated from the seeds of Psoralea corylifolia, a tree native to China with various uses in traditional medicine, followed by extraction with ether and column chromatography combined with silica gel and octyldecyl silane. In this study, the antimicrobial activities of bakuchiol against some oral microorganisms were evaluated in vitro. The cell growth of Streptococcus mutans was i...
