Special Issue Information

Dear Colleagues,

Periodontitis has long been viewed as a localized oral chronic inflammatory disease. However, emerging evidence is highlighting its broader implications for systemic health, reinforcing the concept of an intricate oral–systemic connection. This relationship is grounded in the inflammatory pathways and microbial dissemination that link periodontal pathology with several chronic non-communicative diseases and conditions, such as cardiovascular disease, diabetes mellitus, and adverse pregnancy outcomes. However, there are also data emerging in relation to Alzheimer’s disease, obesity, auto-immune conditions, certain cancers, respiratory diseases, and chronic kidney disease.

The implications for clinical practice are profound. Interdisciplinary collaboration between dental professionals and medical practitioners is vital in ensuring the early identification and management of periodontitis, particularly in patients with systemic risk profiles. Preventive strategies, patient education, and regular periodontal maintenance may contribute not only to oral health but also to a reduction in systemic disease burden.

As our understanding of the oral–systemic axis deepens, it is clearly imperative to view periodontal health as an integral component of holistic patient care. Future research should continue to elucidate causal mechanisms, refine therapeutic strategies, and ultimately, improve patient outcomes across medical disciplines.

The purpose of this Special Issue is to showcase recent studies exploring the oral–systemic connection.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Clinical Medicine is an international peer-reviewed open access semimonthly journal published by MDPI.

Background/Objectives: This systematic review aimed to evaluate the clinical and immunological outcomes of non-surgical periodontal therapy (NSPT) in HIV-positive patients with periodontitis. Methods: Systematic search on four databases (PubMed, Scopus, Web of Science, Cochrane Library) and the gray literature was completed through December 2025. A comprehensive set of clinical parameters and immunological markers were assessed. Three studies met the inclusion criteria and were included in the final synthesis and qualitative analysis. Extracted outcomes included clinical periodontal parameters (PPD, CAL, BoP, PI, GBI, BI) and immunological markers (viral load, CD4+ lymphocyte count, CD4/CD8 ratio, salivary LF, salivary HST, GCF LF, GCF HST). Results: With a very low level of certainty, NSPT was generally associated with significant improvements in clinical periodontal parameters compared to before treatment measurements and HIV-negative individuals. Improvements in immunological status were also reported. Heterogeneity of study designs and reporting standards limited this study’s quantitative analysis. Conclusions: NSPT demonstrates beneficial clinical and immunological outcomes in people living with HIV. However, the very low level of certainty in the available data limits confidence in changes in periodontal status and immune system reconstitution following NSPT in this population; therefore, the findings remain inconclusive and should be interpreted with caution.
