“…One study found that in 256 operated patients, 2 in the CBCT group and 5 in the PAN imaging group experienced permanent sensory disturbances to the IAN. 64 Moreover, in an ongoing study, preliminary results were that 17 of 116 operated patients had temporary neurosensory disturbances arising from the IAN. The distribution was 11 incidents in the CBCT group and 6 incidents in the PAN imaging group.…”

A radiographic examination of mandibular third molars is meant to support the surgeon in establishing a treatment plan. For years panoramic (PAN) imaging has been the first choice method; however, where an overprojection is observed between the third molar and the mandibular canal and when specific signs suggest a close contact between the molar and the canal, CBCT may be indicated. The present review provides an evaluation of the efficacy of CBCT for assessment of mandibular third molars using a six-tiered hierarchical model by Fryback and Thornbury in 1991. Levels 1-3 include studies on low evidence levels mainly regarding the technical capabilities of a radiographic method and the diagnostic accuracy of the related images. Levels 4-6 include studies on a higher level of evidence and assess the diagnostic impact of a radiographic method on the treatment of the patient in addition to the outcome for the patient and society including cost calculations. Only very few high-evidence studies on the efficacy of CBCT for radiographic examination of mandibular third molars exist and, in conclusion, periapical or PAN examination is sufficient in most cases before removal of mandibular third molars. However, CBCT may be suggested when one or more signs for a close contact between the tooth and the canal are present in the two-dimensional image-if it is believed that CBCT will change the treatment or the treatment outcome for the patient. Further research on high-evidence levels is needed. Dentomaxillofacial Radiology (

“…Risk of inferior alveolar nerve injury is associated with anatomic relationship between nerve and the tooth; Smith AC et al, [9] determined in their study that panoramic radiography is the slandered radiological examination to evaluate the anatomic relationship of third molar and inferior alveolar nerve. Guerrero ME et al, [14,15] found that even cone beam computed tomography was not superior to panoramic radiography in predicting post-operative sensory disturbances. Szalma J, et al, [10] in their study concluded that there is no significant advantage of digital panoramic radiography over conventional one.…”

“…There are few studies at the higher levels of hierarchy of diagnostic efficacy in accordance with Fryback and Thornbury 1 , to the authors' knowledge at the time of conducting this review, with only one randomized controlled trial having been published on the impact of CBCT on patient outcomes. 46 The many CBCT machines on the market have different image quality and the diagnostic capability of any machine will vary depending upon mode of operation. Thus, it might be argued that we will never be able to develop "definitive" guidelines with high grading of supporting evidence for CBCT.…”

Objectives: To identify guidelines on the clinical use of CBCT in dental and maxillofacial radiology, in particular selection criteria, to consider how they were produced, to appraise their quality objectively and to compare their recommendations. Methods: A literature search using MEDLINE (Ovid ® ) was undertaken prospectively from 1 January 2000 to identify published material classifiable as "guidelines" pertaining to the use of CBCT in dentistry. This was supplemented by searches on websites, an internet search engine, hand searching of theses and by information from personal contacts. Quality assessment of publications was performed using the AGREE II instrument. Publications were examined for areas of agreement and disagreement. Results: 26 publications were identified, 11 of which were specifically written to give guidelines on the clinical use of CBCT and contained sections on selection criteria. The remainder were a heterogeneous mixture of publications that included guidelines relating to CBCT. Two had used a formal evidence-based approach for guideline development and two used consensus methods. The quality of publications was frequently low as assessed using AGREE II, with many lacking evidence of adequate methodology. There was broad agreement between publications on clinical use, apart from treatment planning, in implant dentistry. Conclusions: Reporting of guideline development is often poorly presented. Guideline development panels should aim to perform and report their work using the AGREE II instrument as a template to raise standards and avoid the risk of suspicions of bias.

Can preoperative imaging help to predict postoperative outcome after wisdom tooth removal? A randomized controlled trial using panoramic radiography versus cone-beam CT

Abstract: For management of postoperative complications for moderate-risk cases of impacted mandibular third molars, careful preoperative radiographic planning followed by an atraumatic surgical approach seems to be valuable, irrespective of the 2D or 3D nature of the preoperative images.
