Comparison of Biofilm Characteristics Between an in Situ Biofilm Model of Supragingival Plaque and Natural Teeth

2016-05-12 00:38:21 | BioPortfolio

Summary

The purpose of this study is to determine in situ the bacterial viability, thickness and bacterial diversity of a biofilm formed on different substrates in comparison to a naturally tooth-formed oral biofilm. In addition, it will be evaluated whether the restraint of oral hygiene measures may influence the development of the PL-Biofilm.

Description

- To calculate an a priori sample size, the following statistical criteria were established: an effect size of 0.35, an alpha error of 0.05 and a statistical power of 87%. Assuming these criteria and using the repeated measures ANOVA test, a sample size of 15 subjects was required.

- Bacterial viability and thickness will be analyse by Confocal Laser Scanning Microscope and Live/Dead BackLight staining solution.

- Bacterial diversity will be analyse by Pyrosequencing the 16S DNAr gene.

Reactive oxygen species inhibit biofilm formation of Listeria monocytogenes.

Although the level of reactive oxygen species (ROS) is altered upon the formation of bacterial biofilm, the relationship between ROS alteration and biofilm formation is still unclear. The aim of the p...

Nanotechnology-based antimicrobials and delivery systems for biofilm-infection control.

Bacterial-infections are mostly due to bacteria in an adhering, biofilm-mode of growth and not due to planktonically growing, suspended-bacteria. Biofilm-bacteria are much more recalcitrant to convent...

Solution-Mediated Modulation of Biofilm Formation by a Cationic Synthetic Polymer.

Bacterial biofilms and their associated infections are a continuing problem in the healthcare community. Previous approaches utilizing anti-biofilm coatings suffer from short lifetimes, and their appl...

An improvised microtiter dish biofilm assay for non-invasive biofilm detection on microbial fuel cell anodes and studying biofilm growth conditions.

Microbial life is predominantly observed as biofilms, which are a sessile aggregation of microbial cells formed in response to stress conditions. The microtiter dish biofilm formation assay is one of ...

Medical and Biotech [MESH] Definitions

A COAGULASE-negative species of STAPHYLOCOCCUS found on the skin and MUCOUS MEMBRANE of warm-blooded animals. Similar to STAPHYLOCOCCUS EPIDERMIDIS and STAPHYLOCOCCUS HAEMOLYTICUS, it is a nosocomial pathogen in NICU settings. Subspecies include generally antibiotic susceptible and BIOFILM negative capitis and antibiotic resistant and biofilm positive urealyticus isolates.

The act of cleaning teeth with a brush to remove plaque and prevent tooth decay. (From Webster, 3d ed)

Those procedures designed to widen the zone of attached gingiva and deepen the vestibular depth which will facilitate the clearance of the area for natural food passage, and provide access for toothbrushing and interdental stimulation.

High molecular weight mucoproteins that form a protective biofilm on the surface of EPITHELIAL CELLS where they provide a barrier to particulate matter and microorganisms. Membrane-anchored mucins may have additional roles concerned with protein interactions at the cell surface.

A plant genus of the family RUTACEAE. Most plants that are called Fagara are actually Zanthoxylum. Some members of Zanthoxylum are reclassified from ELEUTHEROCOCCUS, Melicope, and EVODIA. The twigs are used as dental brushing sticks (TOOTHBRUSHING).
