  to such as doctors and dentists, for a greater in the need To conclude, our research topic highlights the fact that oral health interventions that modify the microbiome show potential for improving oral health outcomes across a variety of pathologies and disease conditions. There is increasing evidence to support the empirical use of dietary modifications or improving patient outcomes. This supplement use demonstrates inter-professional coordination between nutritionists, and primary healthcare providers improve understanding of the connection between nutritional choices in order to promote better oral and general health for the population. Despite promising results, the existing evidence remains limited by significant methodological heterogeneity, including differences in study populations, dietary interventions, probiotic strains, routes of administration, duration of follow-up, and selection of clinical outcomes. Future research should focus on conducting well-designed, adequately powered randomized controlled trials with standardized protocols, clearly defined clinically relevant outcomes, and integrating modern multi-omic approaches to characterize the oral microbiome. Such an approach will allow for a more reliable assessment of the causal relationships between dietary interventions, oral microbiome modulation, and oral and general health outcomes, thereby providing a stronger the development of personalized preventive and therapeutic strategies. A shift from studies primarily focused on describing the oral microbiome interventional research will be toward rigorously designed essential for translating current knowledge into evidence-based dietary and microbiome-targeted strategies for the prevention and management of oral diseases. foundation for Finally, we would like to emphasize the need for research into the use of dietary modulations on systemic health outcomes via the modulation of the oral microbiome. Some studies are already showing the oral microbiome can modulate inflammatory cytokines, nutritional status and healthy aging, emphasizing interconnectedness of oral and systemic health (8, 9).

• Host-microbiome-immune disequilibrium in oral disease: mechanisms, dysbiosis, and precision therapeutics (2026) · Frontiers in Immunology · doi

  The field of oral microbiome research is still limited by several major challenges, including biological, translation, and implementation issues. - There is a lack of large, long-term studies and trials that can test whether microbiome-based or host-microbiome methods can improve diagnosis, prediction, or treatment. - The integration of microbial or AI-derived signals into routine clinical care often remains unclear.

• Fruit and vegetable consumption frequency and tooth-loss transitions across baseline dentition strata in older Chinese adults: a prospective cohort study (2026) · Frontiers in Nutrition · doi

  Further studies are needed to confirm the findings and explore the underlying mechanisms. - Research should investigate the relationship between oral health and diet in different populations and age groups. - Studies should examine the effectiveness of interventions promoting vegetable consumption and oral health in preventing tooth loss and promoting healthy ageing.
