An overlooked connection: oral health status in patients with chronic diseases

Background Oral and systemic health are closely linked. Chronic diseases like diabetes mellitus, cardiovascular diseases, and hypertension increase the risk of dental caries, periodontal disease and tooth loss. Moreover, poor oral health can worsen the status of systemic diseases. Despite this, oral health is often overlooked in chronic disease management. This study aimed to evaluate the oral health status of patients with chronic diseases (PWCD) compared to healthy controls using DIMF-T and DMF-S indices. Methods This retrospective study included 205 participants (106 PWCD and 99 healthy controls) attending the Oral Diagnosis & Radiology outpatient clinic at Bah & ccedil;e & scedil;ehir University Dental Hospital. Comprehensive intraoral and radiological examinations assessed caries lesions, missing teeth, filled teeth, periodontal disease, denture usage, and the prevalence of apical osteitis, soft tissue lesions, and intraosseous lesions. Oral health status was quantified using DIMF-T and DMF-S indices. Statistical analyses were conducted to identify differences between groups. Results The study group (PWCD) exhibited significantly higher median values for missing teeth (MT), decayed surfaces (DS), missing surfaces (MS), DIMF-T, and DMF-S indices compared to the control group (p < 0.001). Chronic periodontitis was more prevalent in PWCD (76.42%) than in controls (45.45%), while gingivitis was more common in the control group (52.53%, p < 0.001). Medication use for systemic diseases was strongly associated with poor oral health outcomes (p < 0.001). However, no significant differences were observed between the groups for decayed teeth (DT), hopeless teeth (IT), or filled teeth (FT). Conclusions PWCD demonstrated worse oral health outcomes compared to healthy controls, highlighting the need for integrated oral and systemic healthcare strategies. Dental professionals should be careful in identifying oral conditions that may signal underlying systemic diseases. Future research should explore the integration of oral health evaluations into routine medical screenings and examine the global practices of oral health management in PWCD.
