Association between Glycated Haemoglobin Levels and Periodontal Health in Adults with Type 2 Diabetes: A Cross-sectional Study in Northern Sudan

Background: This study investigated the relationship between type 2 diabetes mellitus (T2DM) control and periodontal health among adults in Sudan’s North State.
Materials and methods: We conducted a cross-sectional observational study involving 640 adults with T2DM, assessing glycaemic control via glycated haemoglobin (HbA1c) levels and performing comprehensive oral examinations to evaluate periodontal status.
Results: Poor glycaemic control was prevalent, with only 25% of participants achieving the target HbA1c (
