a diameter of 1.5–2 mm. Its proximal extremity is, in turn, characterised by a funnel morphology which is the entrance of the nerve (Fig. 2.12a, b). As the mandibular canal runs into a spongeous bone tissue, its visibility in OPT is closely related to the opacity grade of the surrounding spongiosa. In the subjects with a high level of osteopenia, which causes the absence of optimal contrast conditions, a scarce or absent visualisation of the mandibular canal can occur. In this case, the medical
endodontic damage, expressed by the erosive phenomena within the internal pulp canal which itself appears irregularly widened (Fig. 4.13a–c). 82 4 Caries Contrarily, in some cases, characterised by minor biological aggresiveness and chronic course, the pulp canal can be blocked by the production of reactive dentine, rendering it undetectable by radiological examination (Fig. 4.14). However, we must note that such observation lacks specificity as the radiological non-detection of a pulp canal
treatment through endoral radiograms and in case of sequela and/or major complications, through computed tomography. However, it is true that the radiologist, while analysing an OPT radiogram, often has to face different treatment results and can have difficulty in making the report, especially if a precise query and/or a clinical recall are absent. It must be said that the evaluation, based only on radiological findings, turns out to be very limited and sometimes misleading, if considered
