“…Cone beam computed tomography is considered as the desirable tool for detecting subtle changes, such as ERR because it helps in assessing the region of interest in all the planes and has relatively less amount of radiation when compared with CT scans. 27 Most of the available data on ERR have come from case reports [28][29][30] and retrospective studies of panoramic and periapical radiographs, 11,17,27,[31][32][33][34] and very few studies have been performed comparing panoramic imaging with CBCT, and the information available is still limited. Taking into consideration the importance of diagnosis of ERR radiographically, the study aimed to compare panoramic radiography and CBCT for determining ERR of second molars.…”

Aim: This study was designed to compare the efficiency of conebeam computed tomography (CBCT) with panoramic radiography to discern external root resorption (ERR) in second molars. Materials and methods:This was a retrospective study with a sample size of 50 participants who had a total of 120 impacted third molars visible on panoramic radiographs and CBCT images. The presence of ERR on the neighboring second molar was assessed and the position of impacted third molar was determined using Pell and Gregory classification. The ERR was registered according to Al-Khateeb and Bataineh's criteria. The location and severity were assessed by Ericson et al criteria, and grading of ERR was done as per the criteria given by Nemcovsky. Results:The CBCT was able to locate and identify extremely large number of cases with ERR on second molars in comparison with the panoramic radiographs. Based on Pell and Gregory classification, position B was most common. The ERR on second molars was most commonly seen at the cervical region. Most of the cases had mild severity. As per grading mentioned by Nemcovsky, maximum number of cases were given grade A followed by grade B.Conclusion: According to our study and considering the threedimensional information obtained from CBCT, we found that ERR was better detected with CBCT.Clinical significance: If on panoramic radiographs, a close contact is detected between the second molar and an impacted third molar, CBCT can be advised taking into account the "risk vs reward ratio."
