Abstract: BACKGROUND: The complexity of tooth loss not only compromises oral function and appearance but also has a detrimental impact on oral health-related quality of life. Untreated caries and chronic periodontal disease often lead to partial dentition. This prevalence is further exacerbated by the rising incidence of type 2 diabetes mellitus (DM). These bidirectional effects between diabetes and oral health accelerate tooth loss, necessitating varying levels of prosthodontic intervention to restore oral function and improve patient outcomes. This study aimed to find a correlation between diabetes and the complexity of tooth loss in partially edentulous patients and compare its severity with non-diabetic patients. METHODS: Two hundred partially edentulous patients, non-diabetic (n=100) and diabetic (n=100), reporting to the Department of Prosthodontics, Regional Dental College, Guwahati, India, were classified into four classes according to the Prosthodontic Diagnostic Index (PDI) Classification for partial edentulism. Blood sugar tests were advised as a routine diagnostic procedure. RESULTS: Diabetic patients showed significantly higher tooth loss complexity (Class III PDI) than non-diabetic participants, as assessed by the PDI classification (p = 0.013). Except for gender, other sociodemographic factors and period of edentulism were all associated with higher tooth loss complexity in the non-diabetic group. PDI Class III was more prevalent in diabetic patients associated with a longer history of diabetes and long-term edentulism. Diabetic urban dwellers demonstrated significantly more complex tooth loss than their rural counterparts. CONCLUSION: The complexity of tooth loss was significantly associated with elevated blood glucose level.
