Cone beam computed tomography (CBCT) is an emerging radiographic imaging modality. The diagnostic benefit must exceed the individual detriment that its generally higher radiation exposure may cause. Since limited studies exist on the use and impact of CBCT in paediatric dentistry, a service evaluation was carried out to explore the reasons for CBCT referral and to identify its impact on the treatment plan and/or management in a paediatric dentistry department. Clinical records for all paediatric patients who underwent a CBCT were reviewed, to identify the reason for referral and its influence on diagnosis or management, by comparing the provisional treatment plan with the definitive treatment plan, post-CBCT. A total of 130 paediatric patients underwent CBCT in a 12-month period, of which 52 satisfied the inclusion criteria. CBCTs were most commonly requested for the localisation of unerupted/impacted teeth 14/52 (27%), assessment of supernumerary teeth 12/52 (23%), and to investigate root resorption 9/52 (17%). All CBCTs provided additional information that assisted treatment planning, diagnosis, or management and, most significantly, 16/52 (31%) of treatment plans were changed based on CBCT findings. All CBCTs requested in this study were justified and confirmed or influenced the management of paediatric patients, ultimately reducing the risk of complications and further treatment.

Radiographic Interpretation

A radiographic interpretation is essential to the diagnosis of invasive cervical resorption (ICR) and the difficulty in distinguishing this lesion from internal root resorption has been highlighted in the literature. This paper reports the use of cone beam computed tomography (CBCT) in the diagnosis of ICR. The cases reports describe how CBCT can be used to make a differential diagnosis and also show that the use of this technology can provide relevant information on the location and nature of root resorption, which conventional radiographs cannot. As a result, the root canal treatment was not initially considered. The patients will be monitored and will undergo a scan after a short period of time to detect any small changes. It was observed that both cases benefited from CBCT in the diagnosis of ICR, because this imaging modality determined the real extent of resorption and possible points of communication with the periodontal space.

The Impact

Objectives: CBCT exposes the paediatric patient to a higher X-ray dose and risk than normal dental radiographs. This study has two components: an audit and service evaluation. The audit aims to assess whether the use of CBCT in a Paediatric Dentistry department at a London hospital complies with European guidelines (SEDENTEXCT). The service evaluation aims to explore the influence of CBCT on treatment planning. Methods: Two 6 month audit cycles were completed, where CBCT requests were audited to check whether image justifications comply with SEDENTEXCT. For the service evaluation, a total of 50 patient records were examined for the effect of CBCT on definitive treatment plans. Results: The first audit demonstrated 94% compliance with SEDENTEXCT. After instituting staff training in CBCT, compliance improved to 100%. In the service evaluation, 100% of CBCTs were found to provide information that impacted on the clinicians’ treatment planning, diagnosis and/or management. Of most significance, 44% of treatment plans were changed because of new information provided by CBCT. Conclusions: There are few studies investigating the use of CBCT in paediatric dentistry and the impact of this investigation. This service evaluation shows that CBCT can play an important role in optimising paediatric patient outcomes. The need for robust staff training in CBCT referrals to prevent over prescription is demonstrated in the audit cycles.

Objective: To assess the clinical indications and spectrum of MDP bone scan findings in paediatric patients referred to the National Institute of Nuclear Medicine and Allied Sciences (NINMAS).Materials and Methods: Paediatric patients, age ranged from 2-18 years referred to NINMAS from January 2014 to November 2015 for bone scintigraphy were included in this study. All patients had 99mTc MDP bone scan for various clinical indications. The spectrum of clinical indications and bone scan findings were recorded and analyzed.Results: Total 2323 bone scans with 99mTc MDP were done in NINMAS in the above mentioned period. Among them 91 (3.917%) cases were in paediatric age group. Of which 82 (90.11%) patients with known malignancy were referred for radionuclide skeletal survey. The most common clinical indications were osteosarcoma 30 (32.96%) cases and Ewing’s sarcoma 25 (27.47%) cases followed by five neuroblastoma (5.49%), four (4.39%) rhabdomyosarcoma, three (3.29%) Langerhans cell histocytosis and rest others. Bone scan was positive in 58 (63.7%) cases and normal in 33 (36.3%) cases. Out of 58 cases 38 had features of primary bony lesion, 10 cases had multiple metastases, four cases had primary bone tumour of Ewing’s sarcoma as well as metastases.Conclusion: Bone scan is a popular imaging modality for skeletal survey of paediatric patients in malignancy, both primary and metastatic bone diseases. Bone scanning in paediatric patients contributes a major role in detecting the cause and localizing the pathology of bone. High quality imaging, interpreted by physicians familiar with paediatric diseases, correlation with clinical records and other imaging are mandatory to maximize the benefit.Bangladesh J.

Objective: To quantify tooth volume differences from extracted teeth when using three different three-dimensional (3D) computed tomography (CT)-based imaging modalities. Design: Ex vivo study. Setting: Laboratory and clinics of the University of Alberta. Methods: Cone-beam CT (CBCT) of 12 extracted teeth were scanned using 0.25- and 0.30-mm voxel size from CBCT and a 0.06-mm voxel size from micro-CT (reference standard). 3D reconstructions for each tooth from each imaging modality were made through the software ITK-SNAP®. The mean volume differences between each pair of scanning modalities were calculated and then compared and analysed through a repeated measures ANOVA. Results: The average overestimations of the teeth volume were 15.2% for the high-resolution CBCT and 28.1% for the low-resolution CBCT compared to micro-CT measurements. The differences in absolute volume were 81.6 mm3 and 152.8 mm3, respectively. All differences were statistically significant ( P < 0.05). Conclusions: Orthodontists and researchers who assess root resorption through CBCT imaging should be aware that the depicted volumes may likely be overestimating tooth volume and camouflaging real root volumetric treatment changes.

Cone-beam computed tomography (CBCT) provides images without overlapping anatomical structures, which is important for the diagnosis and assessment of florid cemento-osseous dysplasia. This fibro-osseous lesion that affects the alveolar process without compromising the teeth’ pulp vitality is usually asymptomatic, and bone expansion, cortical disruption, and root resorption are uncommon. Due to its avascular characteristic, surgical procedures are often contraindicated. In this case, a 59-year-old female patient presented with a complaint of pain in the right maxillary central incisor. Panoramic and periapical radiographs showed florid cemento-osseous dysplasia in some regions. The right maxillary central incisor showed an extensive radiolucent image suggestive of root resorption but without fibro- -osseous lesion. For better evaluation and implant planning, CBCT was performed and demonstrated florid cemento-osseous dysplasia adjacent to the right maxillary central incisor, contraindicating implant placement. In other regions, CBCT enabled the identification of the expansive features of this fibro-osseous lesion.

Orthodontic Patients

Unlike patients receiving implants or endodontic treatment, most orthodontic patients are children who are particularly sensitive to ionizing radiation. Cone-beam computed tomography (CBCT) carries risks and benefits in orthodontics. The principal risks and limitations include ionizing radiation, the presence of artifacts, higher cost, limited accessibility, and the need for additional training. However, this imaging modality has several recognized indications in orthodontics, such as the assessment of impacted and ectopic teeth, assessment of pharyngeal airway, assessment of mini-implant sites, evaluation of craniofacial abnormalities, evaluation of sinus anatomy or pathology, evaluation of root resorption, evaluation of the cortical bone plate, and orthognathic surgery planning and evaluation. CBCT is particularly justified when it brings a benefit to the patient or changes the outcome of the treatment when compared with conventional imaging techniques. Therefore, CBCT should be considered for clinical orthodontics for selected patients. Prescription of CBCT requires judicious and sound clinical judgment. The central question of this narrative review article is: when does CBCT add value to the practice of orthodontics? To answer this question, this article presents discussion on radiation dosage of CBCT and other imaging techniques used in orthodontics, limitations of CBCT in orthodontics, justifying the use of CBCT in orthodontics, and the benefits and evidence-based indications of CBCT in orthodontics. This review summarizes the central themes and topics in the literature regarding CBCT in orthodontics and presents ten orthodontic cases in which CBCT proved to be valuable.

ABSTRACT When root resorption of incisors occurs due to impaction of maxillary canines, several factors interfere in the treatment plan, such as the location and severity of root resorption, canine position, lack of space and dental development stage. The case of severe root resorption of permanent maxillary incisors caused by bilaterally impacted permanent maxillary canines and its multidisciplinary therapeutic approach in a 12-year-old girl is presented. After clinical and imaging examination, a treatment plan was outlined including preservation of primary canines, extraction of the permanent maxillary right canine and permanent maxillary left lateral incisor followed by its replacement with the orthodontically tractioned permanent canine and esthetic restoration of the permanent maxillary anterior teeth. One year after treatment, the result was satisfactory and the remaining teeth were still asymptomatic. The risk of root resorption in children with impacted permanent maxillary canines should not be neglected thus reducing subsequent complications.

Abstract Background The vertical thickness of the peri-implant mucosa is associated with the amount of post treatment marginal bone loss. However, the variations in mucosal thickness at the different edentulous sites have been sparsely documented. The purpose of the study was to conduct a survey of the frequency distribution of variations in mucosal thickness at the different sites of the edentulous alveolar ridge and to compare them according to gender. Our study included 125 partially edentulous patients having a total of 296 implant sites. Cone-beam computed tomography (CBCT) scans were obtained by placing a diagnostic template with a radiopaque crown indicator on the ridge to determine the mucosal thickness at the crest of the alveolar ridge. Results The mucosal thickness was 3.0±1.3 mm in the maxilla, which was significantly greater than the mucosal thickness of 2.0±1.0 mm in the mandible (p<0.001). In both the maxilla and the mandible, the mucosa was the thickest in the anterior region, followed by the premolar and molar regions. Sites were further classified into two groups based on whether the mucosal thickness was greater than 2 mm. In the mandible, more than half of the sites showed a mucosal thickness of 2 mm or less. Conclusions Although this study was a limited preoperative study, the vertical mucosal thickness at the edentulous ridge differed between the maxillary and mandibular regions. The majority of sites in the mandibular molar region had a mucosal thickness of less than 2 mm. Practitioners might be able to develop an optimal dental implant treatment plan for long-term biologic and esthetic stability by considering these factors.
