This book was released on 2017 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: Objectives: Bacterial biofilms are ubiquitous, found in a variety of sites within the human body, and are associated with the pathogenesis of dental caries. They are formed when free-floating microorganisms attach to a surface. One such organism, Streptococcus mutans, has adhesins allowing its attachment to tooth surfaces. S. mutans is associated with all forms of human dental caries. S. mutans can rapidly metabolize dietary sugars to acid, locally creating a low pH on tooth surfaces, where it can optimally grow and become more competitive in dental plaque biofilms, in contrast to acid-sensitive bacterial species associated with sound non-carious tooth surfaces. Commensal and natural biofilm aggregates contain multiple microbial species that are believed to co-exist, interact, and form families with high bacteria and niche diversity. In contrast, most biofilms that are chronically infectious tend to have low bacterial diversity with sovereign mono-species such as S. mutans. Hence, it is advantageous to study mono-species biofilms of dental caries-associated bacteria. Although dental biofilms cannot be completely eliminated, their pathogenicity can be lessened through effective oral hygiene measures. Continuous and regular disruption of dental biofilms is imperative for prevention and management of oral infectious diseases. Mechanical methods, most notably tooth brushing and flossing, are required to regularly and effectively disrupt dental plaque biofilms in the human oral cavity. Antiseptics, such as mouth rinses, can also help control dental plaque biofilms, and may gain access to oral sites inaccessible by mechanical methods. Among available antiseptics, sodium hypochlorite is a particularly potent agent against bacteria, fungi, and viruses. Sodium hypochlorite occurs naturally within phagocytic cells (neutrophils, monocytes, and macrophages) participating in the human innate immune response to microbial infection. Several randomized controlled clinical trials support the efficacy of rinsing twice weekly with 0.25 % sodium hypochlorite to improve periodontal health. To date, no studies have been reported concerning the effect of sodium hypochlorite rinsing on dental caries incidence or progression. Several in vitro studies have addressed the effect of dilute sodium hypochlorite on various oral bacteria species. However, there are no literature reports addressing the effect of sodium hypochlorite on bacteria attached to solid surfaces in biofilms. Hence, the objective of this study is to compare the in vitro antimicrobial effect of sodium hypochlorite to another antiseptic agent, chlorhexidine, on the acidigenic and aciduric bacterial species, S. mutans and Lactobacillus casei, both in a free-form (planktonic) state, and as a biofilm attached to two hard surfaces (glass and hydroxyapatite). Methods: The effect of sodium hypochlorite on S. mutans and L. casei was determined by finding the minimum inhibitory concentration (MIC) by broth dilution assays. The MIC was considered to be the lowest concentration of the agent that prevented bacterial growth, resulting in a clear test tube in a broth dilution assay. Experiments with sodium hypochlorite were repeated twice against each bacterial species, and compared to chlorhexidine in similar assays. The effect of a 20-second exposure of MIC concentration (1.0%) of sodium hypochlorite on the growth of S. mutans planktonic cells was measured. Finally, the effect of a 20-second exposure of 1% hypochlorite on S. mutans single-species biofilms was assayed using sterile microplates and the MBEC Biofilm Inoculator (Innovatech). Results: Values for inhibition of growth of planktonic cells were as follows: sodium hypochlorite (MIC = 0.1%; MBC = 0.1%); chlorhexidine (MIC = 0.0015%; MBC = 0.0025%). A 20-second exposure to either solution at the MBC inhibited growth of planktonic cells in refreshed media. Cells adherent to glass or hydroxyapatite pegs were growth-inhibited, but not detached, in refreshed media by a 20-second exposure to 0.2% and 0.4% sodium hypochlorite, and 0.01% and 0.12 % chlorhexidine, but not by more dilute solutions. Conclusions: Chlorhexidine is more potent than sodium hypochlorite, but dilute solutions of both antimicrobial agents inhibited growth of S. mutans mono-species biofilm cells without detachment of cells.
Download or read book Natural Oral Care in Dental Therapy written by Durgesh Nandini Chauhan and published by John Wiley & Sons. This book was released on 2020-04-14 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of increasing antibiotic resistance, stronger antibiotics are reserved for serious active infection, paving the way for a greater use of herbal antibiotics. This book helps dentists in implementing safe and effective natural medicine therapies to complement the current practice guidelines. Oral diseases continue to be a major health problem world-wide. Oral health is integral to general well-being and relates to the quality-of-life that extends beyond the functions of the craniofacial complex. The standard Western medicine has had only limited success in the prevention of periodontal disease and in the treatment of a variety of oral diseases. The dentist needs to be more informed regarding the use, safety and effectiveness of the various traditional medicines and over-the-counter products. Herbal extracts have been used in dentistry for reducing inflammation, as antimicrobial plaque agents, for preventing release of histamine and as antiseptics, antioxidants, antimicrobials, antifungals, antibacterials, antivirals and analgesics. They also aid in healing and are effective in controlling microbial plaque in gingivitis and periodontitis and thereby improving immunity. The 26 chapters in this unique book explore all the measures to utilize the natural oral care obtained from plants, animals and mineral drugs for dental care.

Download or read book Single Cell Analysis written by Tuhin Subhra Santra and published by MDPI. This book was released on 2021-06-02 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cells are the most fundamental building block of all living organisms. The investigation of any type of disease mechanism and its progression still remains challenging due to cellular heterogeneity characteristics and physiological state of cells in a given population. The bulk measurement of millions of cells together can provide some general information on cells, but it cannot evolve the cellular heterogeneity and molecular dynamics in a certain cell population. Compared to this bulk or the average measurement of a large number of cells together, single-cell analysis can provide detailed information on each cell, which could assist in developing an understanding of the specific biological context of cells, such as tumor progression or issues around stem cells. Single-cell omics can provide valuable information about functional mutation and a copy number of variations of cells. Information from single-cell investigations can help to produce a better understanding of intracellular interactions and environmental responses of cellular organelles, which can be beneficial for therapeutics development and diagnostics purposes. This Special Issue is inviting articles related to single-cell analysis and its advantages, limitations, and future prospects regarding health benefits.

Download or read book Bacterial Diversity and Systematics written by F.G. Priest and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bacterial taxonomy as a specialized discipline is practised by a minority but the applications of taxonomy are important to most, if not all microbiologists. It is the implementation of taxonomic ideas and practises which gives rise to identification and typing systems, procedures for the analysis and characterization of biodiversity, hypotheses about the evolution of micro-organisms, and improved procedures for the isolation and implementation of bacteria in biotechnological processes. Without taxonomic theory providing a sound basis to these many facets of microbiology there would be severe problems faced by many scientists working with micro-organisms. Taxonomy comprises three sequential but independent processes; classification, nomenclature and identification. The first two stages are the prime concern of the specialist taxonomist but the third stage should result in identification schemes of value to all microbiologists. As the classification and identification of micro-organisms improves, largely due to the introduction of new technologies, so does its contribution to the subject as a whole. It therefore seemed timely to hold a conference in the autumn of 1993 devoted to microbial identification. Such a topic could not be addressed without some reference to the enabling discipline of classification, but the principal aims were to assess improvements in identification and typing and how these were benefiting microbiological topics ranging from ecological and biotechnological studies of extremophilic bacteria to the use of pyrolysis mass spectrometry in epidemiology. The meeting, which was held in Granada, Spain, was supported by FEMS (FEMS Symposium No.
