Epidemiology of Periodontal Diseases in Individuals With Diabetes in Saudi Arabia: A Systematic Review

Diabetes mellitus (DM) is one of the most common and prevalent metabolic disorders worldwide. It affects men, women, and children and can cause severe organ damage, including kidney damage. The two most common types of DM are Type 1 DM and Type 2 DM. Similarly, periodontal disease (PD) affects a significant portion of the population and involves the tissues supporting the teeth. The bidirectional relationship between diabetes and PD is a well-established phenomenon. However, no comprehensive study on the prevalence of PD among diabetic patients has been conducted on the Saudi population. This systematic review aims to examine the current literature on the impact of these conditions on the Saudi population. A literature search was conducted from January 2001 through June 2024 using Scopus, PubMed, and Google Scholar. An extensive search was performed, duplicates were removed, and inclusion and exclusion criteria were applied. Nine studies were selected for review, adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The retrieved studies confirm the relationship between DM and PDs in regional studies. The review highlights the need for integrated healthcare approaches to manage both conditions effectively. Further research is recommended to understand the causal mechanisms and develop comprehensive treatment strategies.
