Introduction: Oral Health is a key indicator of overall health of the body. While most of us think oral health and systemic health has no link in between them, but **WHO** data tell us differently. According to **WHO,** around _3.5 billion people globally_ are affected with major non-communicable systemic disease like Diabetes Mellitus, Cardiovascular diseases, Alzheimer’s etc. due to poor oral health. Oral-systemic health refers to the bridge between oral health and overall body health, where the problem in the mouth like gum disease or chronic inflammation can worsen systemic conditions (Source: WHO Global Oral Health Status Report) Background: Periodontitis is a chronic inflammatory disease known to affect the supportive structure of teeth. It destroys the soft tissue and bone supporting the teeth which can lead to tooth loss or mobility of tooth. It begins as a simple plaque build-up over a period of time and if left untreated , causes gingivitis, bacteria filled pockets, alveolar bone loss, which can further lead to systemic diseases. Periodontitis also has a _bidirectional relationship with systemic disease._ They both aggravate each other and worsen the case, especially in uncontrolled diabetes which creates a reinforcing cycle often driven by chronic inflammation and bacterial spread. A series of articles in a 2006 _JADA_ supplement addressed the association of periodontal disease to diabetes, CVS, pregnancy outcomes and pneumonia. Periodontal disease is common with prevalence of upto 50% overall. People who smoke are not only at risk of gum disease but also have a higher risk of heart disease, stroke as well as lungs and cancers too. Also babies born to smoker’s women are at increased risk of being at low birth weight.

Periodontitis is termed as sixth complications of diabetes and a person having diabetes is affected 3 times more than average people. Diabetes accelerates the deterioration of PDL tissue through several mechanisms. **MOA: DIABETES → ORAL DAMAGE** Hyperglycaemia impairs neutrophils → poor bacterial clearance 1. Xerostomia → rapid plaque growth 2. Vascular microangiopathy → delayed gingival healing. 3. Elevated glucose in saliva → feeds S.mutans accelerating caries and periodontitis. **Result: 3x** periodontitis risk, **2mm** deeper pockets. Clinical impact: It raises HbA1c by 0.4-0.5%, deep cleaning reduces it equivalently to metformin. (Source: WHO/International Diabetes Federation) - **Cardiovascular disease:** Oral pathogens such as **P.gingivalis** contribute to atherosclerotic plaques, which in turn can increase the risk of myocardial infarction or stroke by 1.4 times. Longitudinal studies indicate that periodontitis accelerates the progression of CVD by elevating inflammatory markers such as CRP. **MOA:** Periodontitis → CVD P.gingivalis LPS invades endothelium → foam cells-\> atherosclerosis IL-6/CRP elevation → plaque instability RISK: 2.3x MI risk , 2.5x stroke risk in chronic periodontitis. CVD → Oral damage Anthypertensives-\> xerostomia → caries/ periodontitis Microangiopathy-\> poor gingival healing RISK: CAD patients = 1.5x periodontitis progression. (Source: ADA/ EMJ) - **Respiratory disease:** Bacteria from mouth travel to lungs, exacerbating pneumonia, COPD, especially in elderly and hospitalised patients. P.gingivalis and F.nucleatum go to the respiratory tract through the mouth and trigger the release of pro-inflammatory cytokines. **MOA:** Poor oral hygiene-\> plaque → pathogen colonisation → aspiration into lungs -\>pneumonia / COPD (Source: Clinical oral-systemic research studies) - **Preterm birth and low birth weight:** Around 15 million babies are born preterm each year and low birth weight remains a major cause of neonatal morbidity and motility. Periodontal disease is associated with 1.5- 2 times increased risk of PTLBW. Periodontal infection is thought to alter intrauterine development through systemic inflammation and dissemination of microflora from periodontal pockets. **MOA:** Periodontal disease (mother) → F.nucleatum dissemination → increase PGs and Cytokines → placental changes → PTLBW. (Source: WHO Maternal health data/ EWJ) - **Stress and depression:** Studies suggest that individuals experiencing chronic stress and depression may require extensive periodontal treatment. Depression increases the rate systemic inflammation and stress related hormones like cortisol alter the immune response by suppressing the immune cells. Global Action Framework: The **WHO’s** Global Oral Health Action Plan (2023-2030) demands we treat oral health as a part of universal coverage , targeting integrated primary care to cut disease prevalence. It provides a roadmap on how to integrate oral health into universal coverage. Stemming from the 2021 WHA74.5 resolution, it builds on prior strategies to promote preventive, equitable care across life stages, aligning with NCD prevention efforts like reducing tobacco use and improving diets. It targets national plans in 80% of countries, a 25% caries reduction and 75% essential service access by 2030. WHO’s Six Strategic Pillars for Action 1. **Governance and Leadership:** Strengthen multisectoral coordination through national oral health plans, policies and leadership commitments, targeting 80% of countries adopting comprehensive strategies by 2030. 2. **Oral Health Workforce:** Train and deploy professionals equitably. 3. **Service and Delivery:** Shift to preventive primary care, phasing out harmful materials.. 4. **Information and Innovation:** Enhance data, research on oral-systemic ties and digital tools. 5. **Risk Factors:** Combat sugar, tobacco via NCD strategies. 6. **Financing:** Boost investments for sustainable oral health within health budgets, fostering partnerships to achieve 75% essential service coverage globally. (Source: WHO Global oral health status report) Practical implementation: - Train non-dentists: Fluoride varnish/ oral exams in primary care. - Unified EHRs: Auto- referrals when HbA1c \>7% or periodontitis detected. - Teledentistry: 30-50% access boost in rural areas. Call to Action: As a healthcare professional embracing the WHO’s integrated vision, let’s transform oral-systemic health from concept to reality. We should implement periodontal screenings in NCD clinics, train interdisciplinary teams on bidirectional disease links, set-up camps and tell people more about PHCs and advocate for national action plans targeting the 2023-2030 goals. We should add oral health metrics to diabetes/CVDs protocols. Promote fluoride varnishes, scaling in primary health care. Join the _ **‘No Health Without Oral Health movement.’** _ References: 1.
