Dental pulp stones may indicate underlying diabetes and vascular risks
Dental pulp stones, often dismissed as harmless calcified deposits in the tooth pulp, may signal deeper systemic health concerns. A recent study published in BMC Endocrine Disorders reveals that people with diabetes are significantly more likely to develop pulp stones and carotid artery calcifications compared to non-diabetics, suggesting these findings could serve as early indicators of cardiovascular risk.
Researchers at Yazd Dental School in Iran examined panoramic radiographs of 107 diabetic patients (67 women, 40 men, ages 25–64, mean 49.7) and compared them with 300 healthy individuals (196 women, 104 men). The study was conducted between December 2021 and February 2022.
Key findings from the study
- Carotid artery calcifications were detected in 41% of diabetic patients versus 14% of healthy individuals.
- Dental pulp stones were found in 38% of diabetics compared with 21% of non-diabetics.
- Diabetic patients were 2.6 times more likely to show carotid calcifications and nearly twice as likely to have pulp stones.
- Individuals with pulp stones were 1.5 times more likely to also exhibit carotid calcifications.
Clinical significance
The findings suggest that panoramic dental radiographs, a routine diagnostic tool in dentistry, may provide valuable insight beyond oral health. By detecting pulp stones and vascular calcifications early, dentists may help flag patients at risk of diabetes-related cardiovascular complications and refer them for timely endocrinology or cardiology care
Researchers emphasized that pulp stones have been “largely ignored in previous studies,” despite their potential relevance to systemic health.
Study limitations
While the study adds to emerging evidence, researchers caution against drawing definitive conclusions. The sample size was relatively small, and the study did not assess factors such as lipid profiles, diabetes duration, or treatment regimens. The authors recommend larger, longitudinal studies to clarify the association and its clinical implications.
“This observation suggests a potential link but does not establish a direct predictive relationship,” the study authors noted.
