Hypothesis

Is directed screening for carotid stenosis with ultrasound indicated in individuals with calcifications in the area of the carotid arteries detected on panoramic radiographs?

Conclusion

Men with calcifications in the area of the carotid arteries should undergo carotid screening if they are otherwise eligible for asymptomatic carotid endarterectomy.

Supporting Evidence

  • Calcification was seen in 176 of 1182 persons undergoing panoramic radiography.
  • Eight persons (6.8%) had carotid stenosis, which was not significant over the 5% threshold.
  • There was a significant sex difference, with all stenoses found in men.

Takeaway

If a doctor sees calcifications in your neck area on a dental X-ray, they might want to check your arteries with an ultrasound, especially if you're a man.

Methodology

This was a cross-sectional study where carotid ultrasound examinations were performed on individuals with calcifications detected on panoramic radiography.

Potential Biases

Potential selection bias as only individuals eligible for asymptomatic carotid endarterectomy were included.

Limitations

The study did not include individuals over 75 years of age and did not analyze the appearance of calcifications.

Participant Demographics

The study included 117 participants, with a higher prevalence of men and a mean age of 66.9 years.
