Introduction. Glycated hemoglobin A1c (HbA1c) is one of the standard indicators for the assessment of metabolic control of diabetes and reflects the risk of complications. Significant complications accompanying diabetes in the oral cavity include gingivitis and periodontitis, which directly increase insulin resistance and disturb metabolic control. Environmental factors such as lifestyle, diet and exercise also play an important role in type 1 diabetes. Physical activity is an important element of diabetes management as it promotes the normalization of body weight. Regular exercise is a very important way to improve your overall health. Aim. Comparison of the relationship between gingivitis and the level of glycosylated hemoglobin with physical activity in adults with type 1 diabetes. Material and Methods. The study included 50 subjects (23 male) with type 1 diabetes mellitus with a median age of 25. The median duration of diabetes in the study group was 11 years. HbA1c was determined and a dental examination with GI assessment was performed. The interview was conducted in terms of physical activity of the studied patients. Results. Comparing the studied variables, higher values ​​of the tested glycosylated hemoglobin and the gingival index were shown in patients without physical activity. There was no relationship between the duration of diabetes mellitus, gender of the examined people and their physical activity. The physically inactive respondents were older than the group declaring physical activity.

Key words: type 1 diabetes, gingivitis, glycosylated hemoglobin, physical activity, civilization disease.
