A method to diagnose diabetes based on the condition of the oral cavity has been identified

Researchers from Fujita Health University in Japan have found that deterioration of oral cavity functions may be associated with an increased risk of developing lifestyle-related diseases - including diabetes, lipid metabolism disorders, and kidney diseases. The work is published in the Journal of Oral Rehabilitation (JOR).

The study involved 118 people over 50 years old who underwent regular medical examinations. Scientists compared the results of blood tests - including glucose levels, cholesterol, and kidney function indicators - with the results of seven tests evaluating oral health. Among them - tongue coating index, mucosal dryness, number of functioning teeth, tongue pressure strength, chewing ability, swallowing problems, and articulation clarity test.

It turned out that people with elevated glucose and glycated hemoglobin (HbA1c) levels had significantly fewer remaining teeth. Participants with elevated cholesterol levels more often had heavy tongue coating and also reduced articulation abilities. Similar correlations were observed in patients with impaired kidney function.

"The results show: decreased oral cavity functions may be a marker and risk factor for the development of metabolic diseases. Therefore, maintaining oral health is an important step towards maintaining overall health," noted the study leader Professor Mitsuyoshi Yoshida.

The authors emphasize that including the assessment of oral cavity functions in regular medical examinations could become an effective measure for preventing chronic diseases.
