This study revisited three oral radiology centers (ORC) and screened the main clinical indications that justified the request for cone-beam computed tomography (CBCT) examination in Endodontics. The databases of three ORCs were searched for requests of CBCT exams taken for Endodontic purposes over the last two years. The extracted data consisted of the total number of CBCT exams, the clinical indication in the endodontic field that justified the CBCT exam, the outcome of each exam (from the report of Oral Radiologists), and demographic data of the patients. From the total CBCT exams (n = 4,583), nearly 13% (n = 611) were taken for Endodontic purposes. Most of the clinical indications were related to root fractures (65%) and periapical lesions/disease (24.1%). Radiologists’ reports hypothesized more often toward periapical lesion/disease (70.5%), root fracture (51.4%) and accidents/complications (25.2%). Some clinical indications significantly varied based on age. In particular, post-traumatic imaging and the investigation of root resorption were more common in young patients, while the prevalence of exams for the investigation of pulpal calcifications and root fractures increased with age. More interestingly, there was a significant disagreement between the clinical indication that justified the CBCT examinations and the outcomes retrieved from radiologists’ reports (p < 0.005). This study illustrates the broad spectrum of CBCT applications for the diagnosis, treatment planning and follow-up in Endodontics. Attention is necessary to the disagreements between clinical indications and imaging outcomes, especially because certain conditions in the routine Endodontics are only visible with the aid of advanced tools.

Cone-beam computed tomography in Endodontics: an exploratory research of the main clinical applications

“…Because of the phase problem of X-ray imaging, it has limited accuracy when used to measure the morphology of the alveolar bone around the anterior teeth [ 5 , 6 ]. However, CBCT can provide accurate information about the labial and lingual sides of the alveolar bone by revealing the deformation and superposition of the teeth [ 7 ].…”

“…The morphology of the alveolar bone is traditionally evaluated with two-dimensional X-ray imaging, although such evaluation is limited around the anterior teeth [ 5 , 6 ]. In recent years, the application of cone-beam computed tomography (CBCT) has been expanding in the field of dentistry and is regarded as an accurate tool for positioning and measurement [ 7 ]. It is a reliable source of data for clinical indicators that are difficult to evaluate, such as alveolar-bone height and thickness.…”

Relationship between alveolar-bone morphology at the mandibular incisors and their inclination in adults with low-angle, skeletal class III malocclusion—A retrospective CBCT study

et al. 2022

PLoS ONE

Objective To quantitatively study the effect of the labial inclination of the mandibular central incisors on the surrounding cortical and cancellous-bone morphology among patients with low-angle, skeletal class III malocclusion, by using cone-beam computed-tomography (CBCT) imaging. Materials and methods The CBCT images of 60 patients with low-angle, skeletal class III malocclusion were divided into lingual-inclination, upright, and labial-inclination groups. The height of the alveolar bone and the thickness and area of the cortical, cancellous, and total alveolar bone were measured separately on each side of the mandibular central incisors. Results The thickness of the labial cortical bone from 6 mm below the cementoenamel junction (CEJ) to the root apex; the thickness of the labial cancellous bone at the root apex; the total thickness of the alveolar bone at the root apex; the area of labial cortical bone; the total area of labial alveolar bone; and the height of the labial alveolar bone were highest in the labial-inclination group (all P<0.05). All these variables were positively correlated with the labial inclination of the mandibular central incisors (all P<0.05). There were no statistical differences between the groups for any of the measurements on the lingual side of the teeth (P>0.05). Conclusion The morphology of the alveolar bone on the labial but not the lingual side of the mandibular central incisors was statistically significantly correlated with the labial inclination of those teeth in patients with low-angle, skeletal class III malocclusion.

“…CBCT examinations were reported to be most frequently requested for the assessment of unerupted teeth (23%), supernumerary teeth (21%), and bony pathosis (20%) in a paediatric dentistry department in London in a retrospective study conducted by Mizban et al (2019). Gallichan et al (2020) investigated the CBCT referral profile in three UK paediatric dentistry departments and reported the most frequent indication for CBCT as the assessment of localised developing dentition (46%). In addition, the most frequently referred FOV was reported as "maxilla anterior" (20x17cm) (68%).…”

Objectives: This study was aimed to evaluate the cone beam computed tomography (CBCT) indications in paediatric and adolescent patients and to investigate their compliance with the guidelines set by the DIMITRA (dentomaxillofacial paediatric imaging: an investigation toward low-dose radiation induced risks) Project.Materials and Methods: CBCT images of paediatric and adolescent patients were selected and evaluated among a total of 12494 CBCT images reviewed retrospectively. Data regarding age, gender, referring department, field of view (FOV), and CBCT indications were recorded. Based on an adaptation of European DIMITRA Project recommendations, CBCT indications were categorized as impacted teeth, trauma, orofacial clefts, dental anomalies, bone pathology, syndromes, and other indications. Follow-up CBCT examinations and incidental findings were also recorded. Data were statistically analyzed at p<0.05 significance level.Results: Most of the 1686 CBCT scans obtained from paediatric and adolescent patients were referred from the Department of Oral and Maxillofacial Radiology (31.2%), followed by the Departments of Orthodontics (25.9%) and Oral and Maxillofacial Surgery (24.6%). The most frequently requested FOV was the maxilla (35.1%) followed by the jaws (maxilla-mandible) (29.3%) and the maxillary canine-incisor region was the most commonly requested region among localised applications (83.1%). The most common indication was impacted teeth (33.5%) followed by bone pathology (32.7%). Follow-up CBCT examinations were recorded mostly for syndromes (33.3%) and orofacial clefts (20.4%).Conclusions: The use of CBCT should be justified on a patient basis and DIMITRA Project recommendations can guide dental professionals in referring CBCT in paediatric and adolescent population.
