Oral Symptoms to Systemic Health: Protocol for a Community-Based Cross-Sectional Study of Oral-Systemic Conditions, Risk Factors, and Healthcare-Seeking Behaviour Oral-Systemic Health and Care-Seeking: a Study Protocol

Abstract

Background: Oral health is closely linked to general health through shared biological pathways, common risk factors, and healthcare-seeking behaviour. Oral symptoms such as toothache, gingival bleeding, oral dryness, and recurrent ulcers affect quality of life and frequently coexist with systemic conditions, including diabetes mellitus, hypertension, and cardiovascular disease. However, oral complaints are often managed independently of general medical conditions, and delays in seeking professional care may contribute to preventable morbidity.
Aim: To describe a protocol for assessing the prevalence and distribution of self-reported oral symptoms, systemic health conditions, associated behavioural risk factors, and healthcare-seeking patterns among adults.
Methods and analysis: A community-based cross-sectional study will enrol 700 adults aged 18 years and above. Data will be collected using a structured, pilot-tested questionnaire covering sociodemographic characteristics, oral symptoms, self-reported systemic conditions, lifestyle-related risk factors, oral hygiene practices, and healthcare-seeking behaviour. Descriptive statistics with 95% confidence intervals will summarise participant characteristics and prevalence estimates. Associations between systemic conditions and oral symptoms will be assessed using the chi-square or Fisher’s exact test, and multivariable logistic regression will estimate adjusted odds ratios for factors associated with oral symptoms and delayed healthcare-seeking. Statistical significance will be set at p < 0.05.
Ethics and dissemination: Ethical approval will be obtained from the institutional ethics committee before recruitment, and written informed consent will be obtained from all participants. Findings will be disseminated through peer-reviewed publication, scientific conferences, and reports to local health authorities.
Conclusion: This protocol provides an integrated framework for examining oral symptoms, systemic conditions, behavioural risk factors, and healthcare utilisation together. The findings are expected to inform integrated oral and general health promotion and strengthen dental–medical referral pathways.
