Biological dentistry: fundamentals and effective Methods: Preventive measures and therapeutic approaches to promote bone and soft tissue healing.

Biological Dentistry is a dynamic field that recognizes the intricate interplay between oral health and systemic well-being. This abstract provides a comprehensive exploration of the core principles and practical applications within Biological Dentistry, highlighting its significance in the context of modern healthcare’s shift towards prioritizing healthspan over mere lifespan.

At the heart of Biological Dentistry lies the profound recognition that oral health is not an isolated concern but an integral component of overall well-being. This understanding begins with a detailed examination of the microbiome and osteoimmunology, two pillars that underpin the biological mechanisms governing oral health.

The oral cavity houses a thriving ecosystem, hosting a diverse community of microorganisms, including over 700 distinct bacterial species, viruses, and fungi. These inhabitants, along with their metabolites and pro-inflammatory mediators, wield a remarkable capacity to exert influence far beyond their immediate domain. Specific attention is devoted to pathogenic microorganisms such as Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans. These bacteria, recognized for their roles not only in causing localized oral conditions but also in driving systemic implications, illustrate the interconnectedness of oral and systemic health. Porphyromonas gingivalis, for instance, has been closely associated with gut dysbiosis and its potential to disrupt the gut microbiome equilibrium. Additionally, the secretion of gingipain by this bacterium has been implicated in the progression of Alzheimer’s disease. Likewise, Aggregatibacter actinomycetemcomitans is examined for its potential to heighten the metastatic potential of pancreatic cancer, thereby highlighting the systemic consequences of oral health. Crucially, the influence of these bacteria often manifests through inflammatory responses, reinforcing the central role of inflammation in both local and systemic pathologies.

Osteoimmunology, a burgeoning field investigating the intricate interaction between the immune system and bone metabolism, assumes critical importance in comprehending the complex relationship between inflammation and bone health. A paradigm shift from viewing bones as static structures to dynamic, continuously remodeling tissues is articulated. The regulatory mechanisms governing this remodeling process, notably RANKL (receptor activator of nuclear factor kappa B ligand) and OPG (osteoprotegerin), which modulate the activity of osteoclasts, are elucidated. Particular emphasis is placed on the influence of bacterial lipopolysaccharides, with Porphyromonas gingivalis as a notable example. These lipopolysaccharides have been shown to upregulate RANKL expression in osteoblasts, ultimately leading to bone loss in periodontal disease.

This exploration underscores the critical need to recognize the intricate connections between oral health, the microbiome, osteoimmunology, and systemic well-being. Such recognition not only underscores the need for a comprehensive approach but also aligns with the evolving paradigm of modern healthcare, which increasingly focuses on healthspan over lifespan. Today’s healthcare system recognizes that longevity alone does not equate to quality of life. Instead, the emphasis is shifting towards enhancing healthspan – the period of life marked by good health and well-being. In this context, Biological Dentistry takes on a pivotal role, as it acknowledges that oral health is an integral element of overall healthspan.

In conclusion, this comprehensive exploration underscores the vital importance of Biological Dentistry within the evolving landscape of modern healthcare. It serves as a compelling argument for healthcare systems to prioritize healthspan, promoting both oral and overall health through a deeper understanding of the connections between oral health, the microbiome, osteoimmunology, and systemic well-being. This paradigm shift represents a crucial step towards enhancing the quality of life for individuals across the lifespan.
