Objective: Pediatric facial arteriovenous malformations (AVMs) are rare but can cause potentially fatal hemorrhages during dental procedures and oral surgery. In this article we present a systematic review of the medical open access literature on pediatric facial AVM. Case report: We illustrate our purpose with clinical dental use of cone beam computed tomography (CBCT) in pediatric embolized facial AVM to define the presence and the position of the right upper impacted canine. Conclusions: We advocate the use of CBCT as additional imaging tool in the follow-up of pediatric dentomaxillofacial AVM, and for depiction of dentoalveolar structures that are inaccessible by conventional dental radiography.

Objective: The aims of this systematic review of the literature were to investigate the uses of cone beam computed tomography (CBCT) in pediatric dentistry and, if possible, identify the indications. Material and methods: A literature search was conducted using the PubMed and Scopus electronic databases and the keywords "CBCT and pediatric dentistry". This search provided us with 1518 references. The selected publications were all clinical articles written in French or English and referring to a pediatric population. After screening, 461 eligible full text articles remained. Results: In total, there were 169 references that met the inclusion criteria. Different topics, mainly relating to orthodontics, anatomy, and cleft lips and palate, were discussed. There was large variability in the information concerning the technical parameters. The radiographic protocols that we analyzed showed a large heterogeneity. Conclusions: The level of evidence provided by our work is limited because only two randomized double-blind controlled studies are included. Two indications can be distinguished: for orthodontics and for the rehabilitation of cleft lips and palate. There are a multitude of radiographic protocols. More research is needed to identify other potential clinical indications as well as to determine a standard CBCT protocol for children and adolescents.

This illustrated article is reviewing currently accepted and recommended indications for use of cone beam computed tomography (CBCT) in orthodontics. We present CBCT of teeth anomalies, impacted canines, supernumerary teeth, troubles of teeth eruption, and external roots resorption related to orthodontic teeth movements. The CBCT should be justified for each patient, and should present added value for diagnostic and/or for treatment planning. The orthodontist needs to interpret and is responsible for all of the field of view.
FR
Cette revue illustrée porte sur les principales indications actuellement recommandées dans la littérature d’utilisation du cone beam computed tomography (CBCT) en orthodontie. Il s’agit des anomalies dentaires, des canines incluses, des dents surnuméraires, des troubles de l’éruption et des résorptions radiculaires externes liées aux traitements orthodontiques. L’examen CBCT doit être justifié individuellement, au cas par cas, et de pouvoir apporter un bénéfice au patient en terme de diagnostic et/ou de traitement orthodontique. L’orthodontiste prescripteur doit être capable d’interpréter et est responsable de l’interprétation de tout ce qui est visible sur l’ensemble du champs de vue du CBCT.

Objective: To investigate the participation of citizens-dental private practitioner in scientific articles about anatomical variations on dentomaxillofacial CBCT. Our null hypothesis was that private practice practitioners are not involved in publications on anatomical variations using cone beam computed tomography. Material and methods: This study was performed from home without access to our university library. Only PubMed database was used to perform our study. We found 384 articles published among 1830 articles corresponding to our inclusion/exclusion criteria. For each selected article we searched for affiliation of all of the authors (university, private dental practice, students, other). We applied a co-creation approach to involve colleagues from private practice in analyzing results of this study. Results: A large majority of authors have university affiliation (96.5%). Only 3% of authors come from private practice. Most of articles belong to the group of 7 emergent economies (E7), and from Asia. 47.9% of 96 journals published only one article on anatomical variations discovered on CBCT. The higher number of articles (18.75%) were published by journals related to endodontics. The 84% of articles were dispersed among a vast span of general and specific dental, and maxillofacial journals. The 68.4% of articles on variations in CBCT were available in closed access and 31.6% of articles were available in open access. Only 6.7% of articles were published in open access without author publication charges (APC). The 31.6% of authors with university affiliation choose open access for their article. 7.8% of authors from private practice were involved in publishing in closed access journals and 2.34% in open access journals. Only 3 articles (0.78%) were published by authors affiliated to private practice without involvement of university authors. 2.6% of articles involved students as co-authors. Authors with other affiliation were involved only in one closed access publication. For the step of co-creation none of 183 private practitioners, and 3/33 (9%) university-affiliated members of Nemesis Facebook group actively participated in analyzing the results of this study. Conclusions: the null hypothesis was accepted: dentists from private practice are exceptionally involved in publications on anatomical variations using CBCT in dentomaxillofacial area.
