CBCT of Swedish children and adolescents at an oral and maxillofacial radiology department. A survey of requests and indications

Abstract

Objectives: This retrospective study investigated requests and indications for cone-beam computed tomography (CBCT) in children and adolescents over a 3-year period at one oral and maxillofacial radiology department. Specific aims were to determine what technical settings were used, which caregivers write the referrals, and how often and for what reasons re-exposure was necessary. Materials and methods: Patients <19 years of age who had been referred to the department and undergone a CBCT scan during 2015-2017 were included in the study. Results: CBCT were made in 617 of the 3847 eligible referrals. The most common referral was from general practice dentists (GPD) (43%). Mean age of the patients was 12.5 years (range: 6-18). Nineteen different types of requests were identified. The most common request was assessment of an ectopic canine with a question about potential resorption of adjacent teeth (38.6%). Forty (6.5%) of the CBCT needed to be re-taken due to patient motion artefacts. Conclusions: The most common request and indication for CBCT examination of children and young adults were to assess an ectopic canine and determine the presence of resorption of adjacent teeth. Referrals from GPDs were the most frequent and the largest age group was the 11-to 15-year olds. The reason for re-exposures was motion artefacts. High scanning speed to reduce motion artefacts and a half rotation (180) to reduce the radiation dose to the patient should be preferred. The need for continuous work with quality and systematic monitoring of radiographic procedures at any radiology department should be given high priority.

Image quality assessment of low-dose protocols in cone beam computed tomography of the anterior maxilla

“…5,38 Currently, the management of canine impaction commonly includes acquiring diagnostic information obtained from CBCT, although little is known about how low-dose protocols could influence the choice of therapy or treatment outcome. 7,8,39 Further clinical studies are needed to identify how application of low-dose protocols can be selected and applied, using information from the current study on the visibility of the anatomical structures.…”

“…[4][5][6] The most common reason for obtaining a CBCT of the anterior maxillary region in adolescents is to assess impacted maxillary canines and their surrounding structures. 7,8 A missed diagnosis or delayed treatment results in 48% of patients developing root resorption of permanent adjacent incisors, which then leads to futher and often complicated orthodontic, surgical, and prosthetic treatments. [9][10][11] While the acquisition of three-dimensional (3D) CBCT volumes is rapidly increasing in popularity, the increased radiation-associated risks that CBCT entails warrant attention, especially regarding pediatric patients who have at least three times greater risk for developing cancer from radiation exposure than adults.…”

The Approaches of Turkish Pediatric Dentists to the Use of Cone Beam Computed Tomography

“…However, there are few studies in the literature investigating the use of CBCT in the pediatric population. 11,16,17,18,19 In this article, it is aimed to investigate the frequency of conic beam computed tomography among Turkish pedodontists, to evaluate its indications and to understand the need for training.…”

“…However, when they categorize children by age, it is stated that the second most common indication is cyst and tumour, especially in the 16-18 age group. 17 In some similar study on the pediatric patient group, CBCT has been used most frequently to evaluate tooth localization and tooth resorption. 11,16 In this study, it was reported that pedodontists most commonly used CBCT in cases of the cyst and/or tumor.…”

Evaluation of dentists’ knowledge about the use of radiology in pediatric dentistry in Serbia

“…Second and third highest scored were orthodontics (26.35%) and dental trauma (16.2%). In a Scandinavian study 9 , it was determined that the two most common reasons for a CBCT are assessment of an ectopic canine and localization of an impacted second premolar. A study published in year 2019 about digital radiography and CBCT 10 states that dental trauma was cited as the reason for using CBCT by 70 subjects (61.3%) subjects, dental development issues by 71% and pathology in the jaws by 75.8%.…”
