Background:
Carotid atherosclerosis has been used to measure the risk for heart disease and stroke. With the use of cone beam computed tomography (CBCT), dentists can diagnose them earlier if the area is calcified. This study aims to assess the radiographic prognosis of calcified carotid atherosclerosis over time.
Methods:
A retrospective pilot study including 50 patients with multiple CBCT scans was conducted. Two parameters were used to assess the prognosis of the calcification:(1) involvement of a new anatomical location on the second scan; and (2) a novel use of calcium scoring system by measuring the Agatston score (AGS), volume score, and density score utilizing CBCT data.
Results:
Out of 50 patients, there were 28 (56%) females and 22 (44%) males. The mean age was 71±7.42. A slight increase in the number, size, and anatomical area of calcification was noted. There was a significant difference between the AGS on the left side and the volume score, P=0.0403, on the right side. The mean value of all scores on the second scan was higher than on the first.
Conclusions:
Our study evaluated the progression of calcified carotid atherosclerosis in asymptomatic patients undergoing multiple CBCT scans. The findings indicate that there was a slight increase in the number, size, and anatomical area of calcification over time. Additionally, the introduction of a calcium scoring system allowed for more comprehensive assessment using the AGS, volume score, and density score derived from CBCT scan data.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
