Periodontal disease is a chronic inflammatory condition resulting in attachment loss and alveolar bone loss. This destruction progresses apically exposing the furcation of multirooted teeth. Although we routinely employ conventional two-dimensional (2D) radiographs for diagnosing bone levels in periodontal disease, inaccuracy caused due to overlap of structures makes diagnosis almost impossible.
To assess the diagnostic accuracy of digital intraoral radiography technique when compared to the cone beam computed tomography in detecting vertical defect depth in grade 2 furcation defects.
A total of 41 grade 2 furcations including 21 buccal and 20 lingual furcations were included. Vertical defect depth was assessed using IOPA and CBCT and then compared.
There was a variation between the IOPA measurements and the CBCT measurements of vertical defect depth. The variation ranged from 0.04 to 5.9 mm. The mean variation between the 2 groups was found to be 1.77 ± 1.39. The mean VDD measured in CBCT was 2.85 ± 1.58 and the mean VDD measured in IOPA was 2.85 ± 1.74.
IOPA is not an accurate method to measure vertical defect depth in grade 2 furcation defects as compared to CBCT.
