“…AZAZ et al 3 found 13% of cases of mild-moderate trismus 10 days postoperatively with slow regression of trismus. CERQUEIRA et al 6 found that trismus was greatest at 24 h and was still present 15 days postoperatively following M3 surgery.…”

“…Of particular interest is that superimposition of the MC and the root of the third molar alone (31 per cent) and appearance of contact of the root with the MC alone (24 per cent) in the absence of any other radiologic criteria are used as indicators of close or intimate relationship. Since these two radiologic criteria have been reported to be present in 40-80 per cent of all impacted mandibular third molars, 13,17,19,35 there is likely a perception that there is a large percentage of cases where there is a close or intimate relationship. This in turn may have an effect on the surgical management of third molar removal.…”

“…A detailed review of the last 30 years of research reveals a focus on nine common radiographic criteria (Table 1). 7,13,15,19,[22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37] The current study assessed both the radiologic modalities and assessment criteria used by Australian oral and maxillofacial surgeons when determining the proximity of MC to third molars. …”

“…19,20 A third clinical sign for direct contact to the IAN is grooves in the root complex from the IAN, which has also been used in some studies. 23,[38][39][40][41] Accuracy of CBCT with a reference standard: The diagnostic accuracy of CBCT using a reference standard has generally been sparsely examined. One study concluded that CBCT was more reliable than PAN imaging for evaluation of number of roots, 40 and a recent study compared three methods, PAN imaging, SCAN and CBCT and found that the modalities seemed equally valuable for examination of tooth angulation, and number and morphology of roots of mandibular third molars.…”

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 (
