The review explores the complex relationship between the gut microbiome and bone health, highlighting their interconnected roles in maintaining overall health. It discusses the impact of gut microbiota on bone metabolism, emphasizing the role of microbial metabolites such as short-chain fatty acids (SCFAs) in regulating bone cell activity. The review also examines the influence of the gut microbiome on immune responses, particularly in relation to chronic periodontitis and coronavirus disease 2019 (COVID-19). It underscores the importance of understanding genetic predispositions and immune dynamics in disease outcomes, advocating for evidence-based medicine and personalized interventions. The review emphasizes the need for a multidisciplinary approach to healthcare that considers the interplay between genetics, immune responses, oral health, and systemic diseases. It highlights the potential of probiotics and prebiotics in modulating the gut microbiome to improve bone health and manage chronic periodontitis. The review also discusses the impact of lifestyle factors, diet, and medications on the gut-bone axis, and the importance of maintaining a balanced gut microbiome for optimal bone health. The findings suggest that targeted therapeutic strategies based on gut microbiome composition could lead to improved patient outcomes in bone-related conditions and other systemic diseases.The review explores the complex relationship between the gut microbiome and bone health, highlighting their interconnected roles in maintaining overall health.
