Abstract

OBJECTIVE:

To evaluate the association between carotid intima-media thickness, buccodental status, and glycemic control in patients with type 1 diabetes.

METHODS:

Cross-sectional study with consecutive cases attended in an outpatient clinic (n = 69). Medical and clinical dental history, HbA1c, lipid profile, treatment period, and daily insulin dosage were recorded. Sociodemographic data and anthropometrical measurements were obtained by standardized questionnaire. Doppler real-time ultrasound was performed by a single experienced vascular radiologist blinded to the study. Assessment of buccodental status was done by the Maxillofacial Unit of the Pediatrics Hospital, and an oral scrape culture was collected.

RESULTS:

The mean age was 11.7 ± 3.0 years, with diabetes 5.1 ± 3.3 years. Mean HbA1c was 8.5 ± 1.7%. Primary teeth were present in 52.2% and bacterial plaque in 94.2%. Buccodental conditions featured caries (63.8%), gingivitis (84%), and enamel demineralization (26.1%): white spot lesions (18.8%) and cavitated lesions (7.3%). Bacteria associated with caries were found in 44.1%. Patients in the highest HbA1c tertile (>8.5%) had greater frequency of buccodental conditions and were positive for Streptococcus mutans and Candida albicans; also, cIMT increased and vessel compliance decreased compared to those in the lowest tertile (<7.0%) (p < 0.05).

CONCLUSIONS:

More buccodental conditions and carotid intima-media thickness increase appeared in the patients with HbA1c level > 8.5%, suggesting onset of atherosclerosis. The correlation between buccodental status and HbA1c values may indicate the connection between inflammatory states of atherosclerosis and type 1 diabetes.
