Yet a persistent translational gap remains: knowledge of oral-systemic relationships has advanced faster than the systems required to convert this knowledge into coordinated, patient-centred care. Dentistry and medicine continue to operate within fragmented professional structures, limiting opportunities for prevention, early risk identification, and longitudinal disease management. We propose Periodontal Medicine 2.0 (PM2.0), an author derived conceptual hypothesis that reimagines periodontal medicine beyond the study of oral-systemic associations toward evidence-calibrated translation and integrated care. Its proposed contribution lies in the clinically significant interactions amongst the four principal domains centred on the periodontal patient: integrated oral-systemic screening, interprofessional collaborative care, precision periodontal medicine, and population health and policy integration. Digital health and AI, patient engagement, health literacy, equity, ethics and implementation science are positioned as cross-cutting enablers. PM2.0 proposes that these domains should interact according to evidence maturity, clinical relevance and implementation readiness, rather than through uniform integration. The framework distinguishes association from causality, screening from diagnosis, diagnostic performance from clinical utility, and technological capability from demonstrated patient benefit. It proposes a risk based, longitudinal pathway linking periodontal assessment with selective risk identification, coordinated care, individualized management and evaluation. The central hypothesis is that appropriately connected and evidence-calibrated functions may generate greater translational value than fragmented approaches. This proposition is testable through clinical, patient reported, implementation, economic, safety and equity outcomes. PM2.0 is therefore presented not as an established historical stage, clinical guideline or validated model of care, but as a literature-informed hypothesis for the future organization of periodontal medicine- from association to evidence based action, and from action to demonstrable impact.</p>","PeriodicalId":73077,"journal":{"name":"Frontiers in dental medicine","volume":"7 ","pages":"1907427"},"PeriodicalIF":2.7,"publicationDate":"2026-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13657953/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149186699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this Perspective, we argue that this omission is a strategic failure for health security, and draw on the contrasting experiences of seven climate-exposed settings (Australia, Fiji, Indonesia, New Zealand, the Solomon Islands, South Africa, and the United Kingdom) to show how environmental stressors disrupt progress in promoting oral health, thereby deepening oral disease inequities. Across these settings, extreme weather damages clinics, interrupts water-dependent processes such as instrument sterilization and community water fluoridation, undermines workforce retention in the places least able to absorb staff losses, and falls hardest on populations already underserved. We propose a four-part framework that recognizes the need to embed oral health within climate-critical infrastructure, develop region-specific vulnerability assessments, protect the workforce in climate-exposed regions, and establish adaptive financing. These recommendations promote environmental sustainability through prevention-oriented oral health policy and the implementation of reduced carbon-emitting oral healthcare service delivery models.</p>","PeriodicalId":73077,"journal":{"name":"Frontiers in dental medicine","volume":"7 ","pages":"1962649"},"PeriodicalIF":2.7,"publicationDate":"2026-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13658057/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149186713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
