Interconnectedness between periodontitis stage, oral hygiene habits, adherence to the Mediterranean diet and nutritional status in Dalmatian kidney transplant recipients: a cross-sectional study

Does adopting a healthy diet improve periodontal parameters in patients susceptible to periodontal disease? A systematic review

OBJECTIVES

The aim of this systematic review is to evaluate evidence relating to whether adopting a diet, associated with improved outcomes for chronic systemic diseases with an inflammatory component, can improve periodontal parameters in patients with periodontal diseases.

DATA SOURCES

Electronic databases and one platform were systematically searched; Medline, Embase, Web of Science and the Cochrane Library including references of relevant studies.

DATA SELECTION AND EXTRACTION

1220 studies were identified of which 9 studies were eligible; 4 RCT's, 1 controlled trial and 4 observational cohort studies DATA SYNTHESIS: 8 out of 9 studies found improved periodontal parameters associated with a diet that was low in refined carbohydrates, low in saturated fats, high in fibre and high in nutrition but the studies were low to medium quality of evidence and the diets, method of recording the diets and periodontal parameters varied between the studies as did the study duration and age of participants.

CONCLUSION

Current evidence supports the hypothesis that adopting a healthy diet has the potential to positively impact periodontal parameters in patients with periodontal diseases, particularly in the older population but the effects may be negated by confounding factors such as smoking. 9 studies were included in the review which were rated moderate or low quality of evidence.

Assessing periodontitis risk from specific dietary patterns: a systematic review and meta-analysis

AIMS

Our goal is to perform a meta-analysis to investigate the risk of periodontitis associated with specific dietary patterns.

METHODS

We employed the PRISMA methodology in a meta-analysis to examine the correlation between dietary patterns and the risk of periodontitis. We systematically searched three online databases from inception to November 2024 to identify relevant studies. Summary estimates with 95%CI were calculated to assess the relationship between specific dietary patterns and the risk of periodontitis. Cumulative estimates were synthesized using random-effects or fixed-effects models. Heterogeneity among studies was evaluated using Cochran's Q and I2 statistics.

RESULTS

In total, we included 19 articles that analyzed 5 dietary patterns The study showed that a diet high in inflammation-promoting foods significantly raised the likelihood of periodontitis (OR = 1.39, 95% CI, 1.09-1.77), in contrast, dietary patterns like the mediterranean diet (OR = 0.96, 95% CI, 0.94-0.98), plant-based diet (OR = 0.92, 95% CI, 0.86-0.98), or dairy-rich diet (OR = 0.76, 95% CI, 0.66-0.87) lowered the risk of periodontitis. The analysis revealed no statistically significant association between a western diet (OR = 1.07; 95% CI, 0.86-1.33) and the risk of periodontitis.

CONCLUSIONS

As dietary diversity and complexity continue to expand, there has been a concomitant increase in the prevalence of periodontal disease. This study has identified specific dietary patterns associated with the risk of periodontitis, particularly highlighting the heightened risk linked to pro-inflammatory diets. These findings emphasize the importance of implementing targeted dietary practices to reduce the incidence of this condition.

The Mediterranean diet and periodontitis: A systematic review and meta-analysis

Periodontitis is a severe oral health condition that affects the soft tissue and bone supporting the teeth. The Mediterranean diet has been proposed as a potential contributor to reducing the risk of periodontitis. This systematic review and meta-analysis aims to explore the association between adherence to the Mediterranean diet and periodontitis. A comprehensive literature search from 1992 to January 2024 was conducted across multiple databases, including PubMed, Scopus, Web of Science, and Google Scholar. The included studies were clinical trials, randomized controlled trials, and observational studies that evaluated the impact of the Mediterranean diet on periodontitis. Data extraction and quality assessment of the included studies were performed using standardized protocols. A meta-analysis was conducted to combine effect sizes from multiple studies. This review included seven studies, comprising one cohort study, five cross-sectional studies, and one randomized controlled trial. While some studies reported a potential link between Mediterranean diet adherence and periodontitis, the overall analysis did not demonstrate a significant association. The meta-analysis revealed an Odds Ratio (95 % Confidence Interval) of 0.77 (0.58, 1.03) for the association between adherence to the Mediterranean diet and periodontitis (p = 0.08). This systematic review and meta-analysis found no statistically significant association between periodontitis and Mediterranean diet adherence. Future research should prioritize the implementation of rigorous clinical studies with longer follow-up periods to better understand the causal association between the Mediterranean diet and periodontitis. Observational studies with larger sample sizes are needed to establish more conclusive evidence regarding the impact of dietary patterns on periodontal health.

Mediterranean diet: a potential player in the link between oral microbiome and oral diseases

Background

The oral microbiome is a complex and dynamic assemblage of microorganisms that colonize different sites of the oral cavity maintaining both oral and systemic health. Therefore, when its composition is altered, oral diseases occur. Among oral inflammatory pathologies, periodontal diseases affect the tissues surrounding the teeth, representing the main cause of tooth loss and one of the most important threats to the oral health. Lifestyle and eating habits influence the composition of the human oral microbiota and the development and progression of oral diseases. In this context, the Mediterranean Diet (MD) model, comprising both healthy dietary choices and lifestyle, is linked to the prevention of several metabolic and chronic-degenerative pathological processes, including oral diseases. Indeed, the MD is a plant-based diet, enriched of anti-inflammatory and antioxidant nutrients, which may induce beneficial effects against dental caries and periodontal diseases.

Aim

This review summarizes the role of the oral microbiome in the development of the oral diseases and the potential of MD in modulating the oral microbiome leading to implications for oral health.

Conclusions

The data collected highlight the need to promote the MD pattern along with the correct hygiene habits to prevent the development of oral diseases.
