The dental plaque biofilm matrix

Area of Science:

• Microbiology
• Oral Biology
• Biochemistry

Background:

• The extracellular matrix (ECM) is vital for microbial biofilms, including dental plaque, organizing cells and coordinating functions.
• Dental plaque ECM comprises carbohydrates, nucleic acids, proteins, and lipids, often forming macromolecular complexes or associating with microbial cell surfaces.
• Cariogenic plaque ECM is rich in glucan and fructan from sucrose metabolism, while subgingival plaque ECM composition remains less understood.

Purpose of the Study:

• To review recent advances in understanding the composition, origins, and function of the dental plaque matrix, with a specific focus on subgingival dental plaque.
• To explore novel strategies for controlling subgingival dental plaque by targeting its biofilm matrix.

Main Methods:

• Literature review of recent scientific advancements.
• Analysis of the structural and functional roles of dental plaque matrix components.
• Evaluation of emerging therapeutic strategies targeting the biofilm matrix.

Main Results:

• The dental plaque matrix plays a critical role in cell arrangement, function coordination, and anchoring cells to tooth surfaces.
• Matrix components are released via lysis, active secretion, or vesicle shedding, facilitating host-microorganism interactions.
• The matrix provides protection against insults and hinders pathogenic plaque eradication, highlighting its importance in oral health and disease.

Conclusions:

• Understanding the dental plaque matrix is essential for developing effective oral health strategies.
• Targeting the biofilm matrix presents a promising approach for controlling dental plaque, particularly in subgingival environments.
• Further research into subgingival plaque matrix composition and function can lead to improved therapeutic interventions.
