CBCT has been a boon in the field of Endodontics. Numerous studies have reported its advantages in diagnosis of periapical lesions. Estrela et al proposed a CBCT-based periapical index, termed as CBCT-PAI to measure and monitor periapical lesion size pre and post-endodontic treatment. CBCT enables in the differential diagnosis of cyst from granulomas by measuring the density from the contrasted images of the periapical lesion. Lofthag- Hansen et al found that CBCT detected 62% more periapical lesions on individual roots if compared with periapical X-ray examinations. Vertical root fractures which are also known as VRF can be detected easily with the help of CBCT. Fractures in Bucco-lingual or mesio-distal directions can be detected. Patel et al in their review of literature found CBCT to be efficacious in endodontic surgery planning and identification of root canals not seen on 2-D images. CBCT not only detects the presence of resorption, but also determines its extent. They also found CBCT is useful in determining root morphology,number of roots, accessory canals and separated instrument in any canal. …show more content…

They found that ultrasound with color power Doppler is an efficient tool for monitoring bone healing and would be a significant contribution to the trend toward radiation-free endodontics. Tikku et al also found that ultrasound and color Doppler imaging were considerably better than conventional radiography detects changes in the healing of periapical lesions. The authors also confirmed that only ultrasound combined with Doppler helps in diffrentiating venous from arterial flow, quantify the amount of flow, identify the anatomy of feeding vessels and offer a visual demonstration of
