conclusions shiitake essential oil is an effective anti-bacterial and anti-biofilm agent on important oral pathogens and has a possible therapeutic potential as an oral anti-biofilm agent. results no inhibitory effect was observed on f. nucleatum biofilms (p > 0.05). significant disruptive properties on a. actinomycetemcomitans at values lower than the mic (3.90 µg/ml) was detected (p < 0.05). ...

use of herbal extracts and essences as natural antibacterial compounds has become increasingly popular for the control of oral infectious diseases. therefore, finding natural antimicrobial products with the lowest side effects seems necessary. the present study sought to assess the effect of punica granatum l. water extract on five oral bacteria and bacterial biofilm formation on orthodontic wi...

INTRODUCTION Biofilm production is considered a potential virulence factor of some Candida species. For this reason, an understanding of biofilm behavior of Candida albicans and its closely related species Candida dubliniensis is key to the development of effective preventive measures for invasive and oral candidiasis. The aim of this study was to compare the capacity of biofilm production by b...

The purpose of this study was to associate oral hygiene frequency and presence of visible biofilm in the primary dentition. The sample consisted of 90 children, aged up to 4 years old, outpatients of the University Hospital of the Rio de Janeiro State University. The examinations were carried out in a dental office by a single trained examiner who was aided by an assistant. The parents answered...

Biofilms are polymicrobial communities that grow on surfaces in nature. Oral bacteria can spontaneously form biofilms on the surface of teeth, which may compromise the health of the teeth, or their surrounding (periodontal) tissues. While the oral bacteria exhibit high tropism for their specialized ecological niche, it is not clear if bacteria that are not part of the normal oral microbiota can...

OBJECTIVES To design a device that allows the formation of in situ oral biofilm with similar characteristics to those from the dental plaque, overcoming the limitations of previous devices. STUDY DESIGN The Intraoral Device of Overlaid Disk-holding Splints (IDODS) was designed and manufactured. To test its validity, five healthy adult volunteers wore them for two and four days allowing the bi...

Biofilm accounts for 65-80 % of microbial infections in humans. Considerable evidence links biofilm formation by oral microbiota to oral disease and consequently systemic infections. Streptococcus sanguinis, a Gram-positive bacterium, is one of the most abundant species of the oral microbiota and it contributes to biofilm development in the oral cavity. Due to its altered biofilm formation, we ...

background : verbascum thapsus (vt) is a medicinal plant that chemical constituents of it revealed the presence of biologically active compounds with antibacterial properties. the aim of the present study was to evaluate the antimicrobial and anti-adherent activities of ethanol extract of (vt) against of three oral streptococci in vitro. methods : in this study, biofilm formation of s. mutans 1...

Recently, growing attention has been paid to antimicrobial photodynamic therapy (aPDT) in dentistry. Changing the microbial composition of initial and mature oral biofilm by aPDT using visible light plus water-filtered infrared-A wavelengths (VIS + wIRA) has not yet been investigated. Moreover, most aPDT studies have been conducted on planktonic bacterial cultures. Therefore, in the present cli...
