Oral Biofilms by S. Eick Pdf

Biofilms are highly organized polymicrobial communities that are embedded in an extracellular matrix and formed on natural and artificial surfaces. In the oral cavity, biofilms are formed not only on natural teeth, but also on restorative materials, prosthetic constructions, and dental implants. Oral diseases like caries, gingivitis, periodontitis, and also pulp inflammation are associated with biofilms. This publication is an up-to-date overview on oral biofilms from different clinically relevant perspectives. Experts comprising basic researchers and clinicians report on recent research relating to biofilms - from general summaries to recommendations for daily clinical work. This book covers all aspects of oral biofilms, including models used in the laboratory, biofilms in dental water unit lines, periodontal and peri-implant biofilms, caries-related biofilms, halitosis, endodontic biofilms, and Candida infections, as well as biofilms on dental materials and on orthodontic appliances. Several chapters deal with anti-biofilm therapy, from the efficacy of mechanical methods and the use of antimicrobials, to alternative concepts. This publication is particularly recommended to dental medicine students, practitioners, other oral healthcare professionals, and scientists with an interest in translational research on biofilms.

Oral Biofilms and Modern Dental Materials by Andrei Cristian Ionescu,Sebastian Hahnel Pdf

This book provides an up-to-date perspective on oral biofilms and dental materials, equipping readers with a sound understanding of their mutual interactions. Experts from across the world comprehensively describe the main strategies that can be followed when designing modern bioactive and biomimetic dental materials, bearing in mind the goal of reducing the occurrence of pathological conditions such as secondary caries and peri-implantitis. The background to the book is the rapid expansion in the use of nanotechnologies and modern techniques to achieve levels of performance of dental materials that were unthinkable even a few years ago. Whereas conventionally dental materials have been regarded as inert, an important paradigm shift is underway: now, these materials are being conceived as bioactive and biomimetic. Modern dental materials can produce a response by interacting positively both with the host and with the biofilm permanently colonizing hard and soft tissues of the oral cavity. These materials increasingly mimic the behavior of the tissues that they are replacing. In documenting the latest knowledge in the field, this book will be of value for both scientists in the fields of nanotechnology, biofilms and dental materials and interested clinicians.

Oral Microbial Ecology by Nicholas S. Jakubovics,Robert J. Palmer (Jr.) Pdf

The oral cavity supports a rich and diverse microbial population. Oral health is dependent on the maintenance of stable microbial communities; disease occurs when this balance is disturbed and more pathogenic species outgrow the commensals. Health and disease in the mouth are active processes in which the ecology of communities, not of single organisms, is paramount. In this book, expert contributors from around the world provide an update on recent developments in the burgeoning field of oral microbial ecology. The chapters are arranged into five sections: microbial populations in oral biofilms, the structure of oral biofilms, communication and sensing within biofilms, health to disease, and new approaches for oral biofilm control. The various topics include: population biology * detection and culture of novel oral bacteria * bacterial catabolism of salivary substrates * structural organization of oral biofilms * the extracellular polysaccharides matrix * extracellular proteins and DNA in the matrix * a holistic view of inter-species bacterial interactions * environmental sensory perception * microbial community interactions of Streptococcus mutans * biofilms in periodontal health and disease * oral biofilms as a reservoir for pathogens * oral biofilms as a device for therapeutic agents * probiotics in oral healthcare. The book is an essential text for scientists interested in oral microbiology, bacterial communities, and biofilms. It is also recommended reading for anyone working in the areas of oral health, the pathogenesis of dental caries, and periodontal disease.

The Root Canal Biofilm by Luis E. Chávez de Paz,Christine M. Sedgley,Anil Kishen Pdf

This book presents the current state of research on the basic scientific aspects of root canal biofilm biology within a clinically applicable context. Root canal biofilms are complex polymicrobial structures adhering to the root canal surface that are formed by microorganisms invading the pulpal space of teeth, and are associated with persistent root canal infections. Concerted efforts to study root canal biofilms have been made in the past decade, resulting in the publication of observational and experimental studies that detail the morphology and biology of these structures in infected root canals. In addition to confirming that bacteria in root canals do not exist in free-floating planktonic states as previously assumed, this new information on root canal biofilm infections has provided an opportunity to re-evaluate conventional clinical protocols and improve endodontic therapeutic measures.

Dental Plaque by Regina TC. Tandelilin, Rajiv Saini Pdf

Dental plaque represents a classic example of both a biofilm and a microbial community, in that it displays emergent properties, i.e. plaque displays properties that are more than the sum of its constituent members. The view of plaque and its constituent microorganisms have shifted from specific plaque hypothesis to a non-specific plaque hypothesis and back again to a theory of specific periodontal pathogens in plaque. Recently dental researchers have begun to view plaque as a biofilm. Oral biofilms are very heterogeneous in structure. Dense mushroom-like structures originate from the enamel surface, interspersed with bacteria-free channels used as diffusion pathways. The channels are probably filled with an extracellular polysaccharide (EPS) matrix produced by the bacteria. The bacteria engage in both cooperative and competitive interactions. In order to break down complicated host macromolecules and extract nutrition, bacteria combine their metabolic efforts. A variety of diffusible chemicals are used in cell-cell signaling, which helps the microbial community's members coordinate their gene expression. Bacteria in biofilms use a system known as "quorum-sensing" to optimize their virulence factors and survival. Dental biofilm pathogenicity in the oral cavity is magnified by two biofilm characteristics: increased antibiotic resistance and the inability of the community to be phagocytized by host inflammatory cells. The key characteristics of biofilm that could be targets for pathogen management include its behavior as an adhesive mass with viscoelastic properties, its activity as a coordinated multi species community in which cells communicate via small molecules, and its inflammatory disease potential. To understand the mechanism of change from health to disease and their interaction with the host's reactions, more in-depth information of the metabolic activities controlling and governing biological processes at the species-species level is now required. An improved understanding of biofilm will lead to new strategies for management of oral diseases. In the near future, it is expected that the correlation between biofilm maturation and activation of specific genes of the inner microorganisms will be clarified at the molecular level.

Control of biofilms to control caries by Jin Xiao,Xiaojing Huang,Mingyun Li,Richard L. Gregory,Keke Zhang Pdf

Dental caries, a biofilm-mediated multifactorial dynamic disease, is identified as a type of global public health problem. Microbes including commensals and opportunistic cariogenic pathogens such as Streptococcus mutants embedded within an extracellular matrix form a highly organized biofilm 3D structure. Homeostasis of oral biofilm plays a vital role during caries development according to the ecological plaque hypothesis. Under unfavorable conditions such as excessive sugar intake, an excess of acid is produced by biofilm which resulted in an acid-induced selection, promoting the growth of acidogenic and aciduric microbes including opportunistic cariogenic bacteria. The transition from eubiosis to imbalance finally promotes tooth hard tissue destruction. Thus, controlling biofilms is key to controlling caries. Though caries has been studied for decades, the current situation of this disease is not optimistic. From the perspective of biofilm, firstly, there is a lack of in-depth analysis of pathogenic mechanisms. Besides, mature biofilms are mechanically hard to eliminate and much more resistant to antimicrobial agents than bacterioplankton. Moreover, materials that filling of decayed teeth are short of antimicrobial activity which contributes to secondary caries.
