Biofilm – what it is and why it matters

Biofilm – what it is and why it matters

Biofilm refers to communities of bacteria that form in various environments, including the human body. These bacterial clusters, if left unchecked, undergo maturation, leading to the development of pathogenic bacterial complexes that can result in oral health issues such as dental caries, gingivitis, and periodontitis. Identifying, disrupting, and managing these biofilms is crucial for the success of treatments and the overall well-being of patients. The significance of addressing biofilms lies in their connection to oral health, which is often considered a vital aspect of overall well-being. Poor dental health not only serves as the root cause of various oral problems and systemic diseases but can also have negative psychological effects, impacting self-esteem. Despite ongoing efforts to prevent biofilm formation on dental enamel, the challenge persists due to the universal phenomenon of adsorption and adhesion by sessile cells on dental tissue. Therefore, rapid diagnosis, vigilant surveillance, and regular interventions are essential to effectively combat the consequences of biofilm formation and promote optimal oral health.

Dental biofilm: Risks, diagnostics, and management by Rina Rani Ray

Excerpts from the clinical article:

Biofilms are communities of bacteria that exist in both the human body and the environment. If left unattended, these biofilms undergo maturation, and the resulting pathogenic bacterial complex can lead to dental caries, gingivitis, and periodontitis. It is important to identify, disrupt, and manage these biofilms to ensure the success of your treatments and the well-being of your patients.


Oral health is considered to be wealth, as poor dental health is not only the root cause of various oral problems and various systemic diseases but also imparts negative psychological effects by damaging self-esteem. Despite many promising strategies for the prevention of biofilm formation on dental enamel, the pervasive phenomenon of adsorption and adhesion by the sessile cells on dental tissue is becoming a universal phenomenon. Rapid diagnosis with strong surveillance and regular use of…

Dental plaque as a biofilm and a microbial community – implications for health and disease – Philip D. Marsh

Excerpt from the clinical article:

Dental plaque is the community of microorganisms found on a tooth surface as a biofilm, embedded in a matrix of polymers of host and bacterial origin. Of clinical relevance is the fact that biofilms are less susceptible to antimicrobial agents, while microbial communities can display enhanced pathogenicity(pathogenic synergism). The structure of the plaque biofilm might restrict the penetration of antimicrobial agents, while bacteria growing on a surface grows slowly and display a novel phenotype, one consequence of which is a reduced sensitivity to inhibitors.


The key to a more complete understanding of the role of microorganisms in dental diseases such as caries may depend on a paradigm shift away from concepts that have evolved from studies of classical medical infections with a simple and specific (e.g. single species) etiology to an appreciation of ecological principles. The development of plaque-mediated disease at a site may be viewed as a breakdown of the homeostatic mechanisms that normally maintain a beneficial relationship between the resident oral microflora and the host. … This way, the clinician does not just treat the end result of the caries process but also attempts to identify and interfere with the factors that, if left unaltered, will inevitably lead to more disease.

Unlocking the Power of Bioactive Materials in Restorative Dentistry

Unlocking the Power of Bioactive Materials in Restorative Dentistry

In the realm of modern dentistry, the quest for materials that not only restore but actively promote oral health has led to a revolutionary breakthrough: bioactive materials. These innovative substances represent a paradigm shift, transforming traditional restorative procedures into opportunities for proactive dental care. As we delve into the realm of bioactive materials used in restorations, we uncover a world where dental treatments not only repair but also rejuvenate, offering patients a path to lasting oral health and vitality.

Join us on a journey to explore the science, benefits, and clinical applications of bioactive materials, as we unlock their transformative potential in restorative dentistry.

WATCH: Bioactive Dental Materials

In a one-hour video, Dr. Robert Lowe explores the transformative potential of bioactive dental materials in restorative dentistry. He discusses how these materials contribute calcium and phosphate ions, aiding in the natural processes of rebuilding healthy apatite. This represents a new paradigm in restorative dentistry, offering exciting possibilities for enhancing dental treatments.

READ: Clinical Study on Natural Layering Concept

A new shading concept based on natural tooth color applied to direct composite restorations by Didier Dietschi, DMD, PhD, Stefano Ardu, DMD, Ivo Krejci, DMD

Excerpts from the clinical study:

Influence of the natural layering concept on shade recording:
The quality of the final restoration, of course, depends on a correct shade recording. According to the natural layering concept, only 3 steps are involved: (1) selection of dentin chroma in the cervical area, where enamel is the thinnest, using samples of the composite material, (2)selection of enamel tint and translucency, by simple visual observation, and (3) preparation of a simplified chromatic map(visually or through an intraoral photograph) to decide whether the application of effect materials is needed.


The natural layering concept has enabled this objective to be achieved in a predictable way by incorporating newly acquired knowledge about natural tissue optical properties into contemporary composite systems. This advance can be regarded as a milestone in operative dentistry, as it will give direct composite application a tremendous advantage, enabling a larger number of patients to receive more conservative and esthetic restorations.

Bioactive Restorative Dental Materials Hold Great Promise in Terms of Function, Use by John Fluke, DDS

Excerpt from the article:

Bioactive materials have been a part of dentistry for several years, but what makes these materials markedly different from traditional dental materials? With bioactive materials, direct dental restorations can interact with the oral environment and encourage activity that can be beneficial to both the lifespan of the restoration, but also to the health of the restored tooth and surrounding dentition. Understanding what bioactive dental materials are, how they work, and where and when they are best used is an important part of deciding on the best restorative material for a case.
