    Opis:
    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.

    Opis:
    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.

    Opis:
    Objective: Firstly, this review aims to analyse the recent literature about three-dimensional (3D) diagnostic imaging in complex and compound odontomas and compare it to two-dimensional (2D) imaging. Panoramic radiographs help to evaluate the vertical position of odontomas, and occlusal radiographs are used to evaluate the proximity to adjacent teeth. However, cone beam computed tomography (CBCT) can offer volumetric images, and therefore, a more accurate three-dimensional analysis. Secondly, this research aims to construct an open classification matrix for complex and compound odontomas for dentomaxillofacial CBCT radiology protocols based on a systematic literature review. Material and methods: Two systematic literature searches were conducted in PubMed (Medline), on 2 February 2022 concerning classification systems, and on 5 February 2022 concerning CBCT images. Results: In total, these searches revealed 391 papers by reviewing the databases mentioned above. Six articles were selected for inclusion on classification of odontomas and 13 articles were found on CBCT imaging. Consequently, the construction of an open classification matrix for compound and complex odontomas for dentomaxillofacial CBCT radiology protocols was performed using these 19 articles. Conclusions: CBCT offers a more precise position and accurate diagnosis of complex and compound odontomas compared to 2D imaging. Consequently, it enhances the detailed view of the site (multiple or unique), location (intraosseous, partially or completely extragnathic), size, extension (bony expansion, thinning or perforation cortical bone), density and type (denticulo type, particle type, denticulo-particle type, denticulo-amorphous type, amorphous tissue), relationship (with the crown or root of the definitive tooth), adjacent teeth resorption (deciduous or definitive), adjacent teeth (retention or impaction), and distance with adjacent structures (inferior alveolar nerve, sinus maxillaris), as well as adequate surgical planning. Moreover, this research presents an open classification matrix for the most complete description of compound and complex odontomas when analysing CBCT imaging.

    Opis:
    Objectives: The Pierre Robin sequence (PRS) is defined by retromicrognathia, glossoptosis, and sleep apnea and can also be associated with cleft palate. Diagnosis, management and mandibular catch-up growth are still controversial issues in PRS patients. The aim of our retrospective study was to evaluate in three dimensions (3D) the airway space and mandibular morphology in PRS compared to a normal control group patients in the pre-orthodontic period of life. The null hypothesis was that we would not find a significant difference between the PRS and control group patients in oropharyngeal airway volume measurements. Material and methods: We analyzed 9 PRS patients (mean age: 8 years-old) who underwent cleft palate surgery in the first four months of life, performed by the same surgeon using the same technique. Cone-beam computed tomography (CBCT) was performed in these patients after local ethical committee approval. The control group consisted of 15 patients (mean age: 9 years-old) with CBCT already performed for other reasons. 3D Slicer was used in both groups for semi-automatic segmentation of the airway space. Two independent observers performed semi-automatic segmentations twice in each patient with a one- week interval between the two series of measurements. Airway volume was automatically measured using 3D Slicer. We also developed a 3D cephalometric analysis with Maxilim software in order to define a 3D mandibular morphology which consisted of 25 landmarks, 4 planes, and 23 distances. Two independent observers performed the 3D cephalometric analysis twice for each patient, with a one- week interval between the two series of measurements. Results: There was no significant difference in the intra- and inter-observer measurements between the PRS and control groups for airway space volume (p<0.05). However, there was a significant difference in the shape of the mandible between the PRS group and the control group (p<0.05). Conclusions: Vertical ramus width and mandibular global anteroposterior length were significantly lower in the PRS group. Mandibular hypoplasia could be found in PRS patients not only in the horizontal dimension. Nemesis relevance: the null hypothesis was confirmed. Moreover we failed to find exactly the same control group under 9 years-old due to radioprotection restrictions of application of cone beam CT in children.

    Opis:
    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.

    Opis:
    Objective: Taurodontism is a developmental disorder with enlargement of the body of the tooth and lack of cervical constriction, which results in a large pulp chamber and small roots with the apical displacement of furcation. Taurodontism exists in deciduous, and definitive unilateral, and bilateral teeth. We found that taurodontism was also described in 67 syndromes. We proposed a review of the open access literature on taurodontism, a new clinical classification of taurodontic teeth with illustrations from free open access literature, and from our case serie of 15 patients. Material and methods: We performed a systematic search for articles with free full text about taurodontism. The search was performed by one observer in PubMed database. We found 168 articles, and after application of inclusion/exclusion criteria we finally selected 136 articles for the review. Results: we provided 34 figures of taurodontic teeth related to: 1) Unilateral mandibular first premolar, 2) Unilateral mandibular second premolar, 3) Bilateral mandibular first and second premolar, 4) Bilateral upper maxillary first premolars, 5) Bilateral mandibular second molars, 6) Bilateral upper maxillary second premolar and left first molar, 7) Bilateral upper maxillary third molars, 8) Bilateral upper maxillary first and second molars, 9) Bilateral upper maxillary first, second, and third molars, 10) Bilateral upper maxillary molars (third molars, second, and first left upper molars), and mandibular molars (first right, and left mandibular molars, right third molar), 11) Bilateral upper maxillary molars (first, second, third right, and left upper molars), and mandibular molars, 12) Unilateral first mandibular premolar with cleft, 13) Bilateral molars of the mandible and the upper maxilla (adolescent patient who received chemotherapy at the age of 3-years-old to treat retinoblastoma), 14) Unilateral first maxillary molar (Treacher-Collins syndrome). Conclusions: We proposed a new clinical classification of taurodontic teeth based on hypo-, meso-, and hypertaurodontism, and on different types of deciduous, and definitive teeth (42 boxes). We were first to provide free reference images for: 1) upper maxillary second premolar hypertaurodontism, 2) mandibular second premolar mesotaurodontism, 3) upper maxillary third molar meso-and hypertaurodontism, 4) mandibular first molar hypotaurodontism, 5) mandibular third molar mesotaurodontism. We were also first to freely illustrate taurodontism related with chemotherapy, cleft palate patients, and Treacher-Collins syndrome.

    Opis:
    Objective: to explain the meaning and to illustrate technical artifacts (aliasing as well as the ring artifact) and beam hardening (metal artifact) that can be present in the dentomaxillofacial cone beam computed tomography (CBCT), and to check the accessibility of free illustrations of these artifacts in medical publications. Material and methods: One observer applied five search equations using database PubMed. The exclusion criteria were: experimental studies, animal studies, studies not related to dentomaxillofacial area, and articles with closed access. There was no time limit for the search of articles. We limited our search to English and French language. Results: Only 3 articles out of 434 publications were retained after application of inclusion/exclusion criteria. In these articles only 4 annotated figures were freely accessible in medical publications from PubMed. In this paper we presented examples of aliasing, ring artifact, and beam artifacts from I-CAT, Carestream 9000 3D (Kodak), and Planmeca Promax 3D Mid CBCT. The intensity of beam hardening artifact varies from major degradation of image (i.e., subperiosteal implants, bridges, crowns, dental implants, and orthodontic fix appliances), through mean degradation (screws securing titanium mesh, head of mini-implant) to no beam hardening on metallic devices (orthodontic anchorage, orthodontic contention wire) or on dense objects (endodontic treatments, impression materials, Lego box). Some beam hardening artifacts arising from nasal piercing, hairs, or hearing aid device may be present on the image but they will not disturb the evaluation of the field of view. Conclusions: reduction of aliasing artifact is related with the improvement of detectors quality. The presence of ring artifact means that CBCT device has lost its calibration. The field of view (FOV) needs to be reduce in order to avoid scanning regions susceptible to beam hardening (e.g., metallic restorations, dental implants). Finally, the accessibility to open knowledge on technique -related CBCT artifacts seems extremely limited when searching at PubMed database.

    Objective: to build a descriptive classification of premolar and molar supernumerary teeth (ST) when preparing the cone beam computed tomography (CBCT) report. The aim is also to share wide range of CBCT images in the open access publishing model. Material and methods: For our review we systematically searched for articles from PubMed with 1) free full texts on ST in molar and premolar area and using CBCT, and 2) articles providing with information on complications related with the presence of ST in molar and premolar area. We also added to our review studies providing with classic ST classifications in premolar and molar area. Results: We found 29 cases of ST, and we freely illustrated them with 84 figures. We separated our pictorial review in: 1) unilateral ST in the mandible, 2) unilateral ST in the maxilla, 3) unilateral undersized ST, 4) bilateral ST, 5) ST with additional features, and 6) cases with major hyperdontia. Conclusions: we build up the classification matrix for premolar and molar ST with 11 descriptors and 50 boxes. The descriptors were: 1) location if the ST crown in axial view, 2) vertical location of the cusp tip in relation with closest erupted tooth in coronal view, 3) shape, 4) distribution, 5) Position (in relation to normal tooth eruption) in sagittal view, 6) State of eruption of the ST in the sagittal view, 7) Follicle size measurement in sagittal view, 8) External root resorption of adjacent teeth by ST and its location in relation to the long axis of the involved tooth, 9) Internal resorption of ST, 10) Adjacent tooth complication, and 11) Damage to surrounding structures if ST removal. The open access figures from the literature illustrated 11 boxes. With our pictorial review we were able to illustrate 45 out of 50 boxes, and freely provide the readership with the most complete description of ST in premolar and molar area on CBCT than in previously published studies.
    Мета: скласти описову класифікацію надкомплектних зубів (НКЗ) в ділянці премолярів та молярів для використання в описі конусно-променевих комп’ютерних томограм (КПКТ). Метою також є поширення значної кількості зображень КПКТ за моделлю відкритого доступу. Матеріали та методи: Для складання огляду ми провели пошук безкоштовних для перегляду повних статей на PubMed з інформацією про: 1)  КПКТ НКЗ у ділянці премолярів та молярів; 2) Ускладнення, пов’язані з наявністю НКЗ в ділянці молярів та премолярів. До огляду також були додані класифікації НКЗ в ділянці премолярів і молярів, представлені у інших дослідженнях. Результати: Нами було знайдено 29 клінічних випадків НКЗ, які ми проілюстрували 84-ма малюнками. Ми розділили наш ілюстративний огляд на: 1) Однобічні НКЗ на нижній щелепі; 2) Однобічні НКЗ на верхній щелепі; 3) Однобічні мікродонтичні НКЗ; 4) Двобічні НКЗ; 5) НКЗ з додатковими особливостями; 6) Випадки значної гіпердонтії. Висновки: Створено класифікаційну матрицю для НКЗ в ділянці премолярів і молярів з 11 дескрипторами та 50 блоками. Дескрипторами були: 1) розташування коронки НКЗ в аксіальній проєкції, 2) вертикальне розташування вершини горбка у відношенні до найближчого прорізаного зуба в корональній проєкції, 3) форма, 4) розподіл, 5) положення (у відношенні до положення нормально прорізаного зуба) в сагітальній проєкції, 6) Стан прорізування НКЗ в сагітальній проєкції, 7) Розмір фолікула в сагітальній проєкції, 8) Зовнішня резорбція коренів сусідніх зубів, спричинена НКЗ та його розташуванням у відношенні до довгої осі ураженого зуба, 9) внутрішня резорбція НКЗ, 10) ускладнення у сусідніх зубах, спричинені наявністю НКЗ, 11) ушкодження навколишніх анатомічних структур внаслідок видалення НКЗ. Малюнками з літератури, що знаходилася у відкритому доступі, було проілюстровано 11 блоків. У нашому ілюстративному огляді нам вдалося проілюструвати 45 з 50 блоків, і надати читачам вільний доступ до більш повного опису КПКТ НКЗ в ділянці премолярів та молярів, ніж у раніше опублікованих дослідженнях.

    Opis:
    The solitary median maxillary central incisor syndrome (SMMCI) is a rare autosomal dominant genetic syndrome characterized by the presence of a single central incisor positioned along the midline in both primary and permanent dentition. It is often associated with the holoprosencephaly spectrum, a group of brain and facial malformations. The etiopathogenesis of SMMCI is believed to involve embryonic developmental defects occurring between the 35th and 38th day of gestation, primarily affecting midline facial structures. Several genetic factors, including mutations in the Sonic Hedgehog gene on chromosome 7 and other genetic variants, have been implicated in SMMCI development. Diagnosis is typically made through clinical examination, prenatal ultrasound, and postnatal dental evaluation. Management of SMMCI requires a multidisciplinary approach involving pediatricians, otolaryngologists, neuro-pediatricians, and genetic counselors. Dental interventions may include extraction and space maintenance, orthodontic treatment, prosthodontic options, or esthetic considerations. Further research is needed to understand better the underlying mechanisms and genetic factors associated with SMCI, which will contribute to improved diagnosis and management of this syndrome.

    Opis:
    Objective: to present and to illustrate a new methodology for daily practice in cone beam computed tomography (CBCT) interpretation and reporting in cleft lip palate (CLP) non syndromic paediatric patients. The proposed protocol is based on clinical experience and on systematic search of the literature. Material and methods: We performed two types of systematic search of articles: 1) articles related to the use of CBCT in CLP patients, and 2) articles related to the reporting and interpretation of the CBCT images by radiologists. We used two databases PubMed and Google scholar. Results: For indications of CBCT in CLP patients we found in PubMed 378 articles and 48 articles were selected for the review; in Google scholar we found 463 articles, and 9 articles were selected for the review. 2) For reporting in CBCT we found 956 articles in PubMed, and 9 articles were selected for the review. Conclusions: We presented the 6-steps system for interpretation and reporting information from CBCT of CLP paediatric patients: 1) Step 1 (axial view): presence or absence of bone bridge remnants of alveolar bone graft; Step 2 (3D dental tissue reconstruction): description of dental arch tooth by tooth, search for agenesis and supernumerary teeth, description of variation in the position of the tooth explaining the type of existing translation and rotation; Step 3 (coronal view): cleft palate pathway and its extension; anomaly in maxillary, ethmoid and sphenoid sinuses if existing; Step 4 (sagittal and coronal view): checking of the opening (calcification sites) of the sphenooccipital synchondrosis, and checking of anomalies of the occipital bone; Step 5 (3D bone tissue reconstruction): C1-C2 vertebra anomalies; Step 6 (3D soft tissue reconstruction): external ear anomalies. We illustrated our methodology with 46 figures from 5 CBCT of CLP patients.

    Opis:
    Objective: Paracondylar (PCP) and epitransverse processes (ETP) represent rare types of articulations that can occur between the occipital bone and the transverse process of atlas vertebra. Material and methods: Five systematic search strings were conducted on PubMed database on 14.01.2022. The search was conducted by one observer to identify studies on PCP, and on ETP in living patients. Open and close access articles were selected as this topic is infrequently described in the main medical literature. Results: We provided with a pictorial review of 1) Paracondylar tubercle, 2) Unilateral PCP with cylindrical shape, 3) Unilateral PCP with pyramidal shape, 4) Unilateral PCP with lateral joint with transverse process, 5) Unilateral PCP with superior joint and partial fusion with transverse process, 6) Unilateral ETP with neo-condyle and joint with occipital condyle, 7) Unilateral ETP with joint with occipital bone, 8) Unilateral ETP with a bony bridge with lateral mass (ponticulus lateralis), and 9) Bilateral variation: paracondylar mass and ETP. Conclusions: Six figures were found in the selected literature and belong only to articles published in closed access. We provided with additional 41 open access freely available figures. We were first to present CBCT reference figures of: 1) Unilateral paracondylar tubercle, 2) Fusion of PCP with the transverse process of C1, 3) Joint between ETP and the lateral side of occipital condyle, and 4) Presence of bony bridge (ponticulus lateralis) between ETP and the lateral mass of C1. We were also first to describe a bilateral mixt variation with paracondylar mass on one side and ETP on the other side of C1. An open and accessible knowledge support (such as Nemesis journal) is needed to easily find clinical reference CBCT figures of craniocervicofacial bone variations.

    Opis:
    Stafne bone cavity (SBC) is a rare entity to find on panoramic radiography and on cone beam computed tomography. We reviewed in a systematic way the open-access literature from PubMed and DOAJ. We also proposed a new methodology consisting of collaboration with private practitioners, application of participative science approach, and open science practices, and using social media tool to obtain and describe seven different cases of SBC. We finally propose a new matrix table for classification of anatomical types of SBC already described and those yet to be described in open-access literature.
    Defekt Stafnego (Stafne's bone cavity - SBC) jest rzadko spotykany w radiografii pantomograficznej i stożkowej tomografii komputerowej. Dokonaliśmy systematycznego przeglądu literatury otwartego dostępu PubMed i DOAJ. Zaproponowaliśmy również nową metodologię polegającą na współpracy z prywatnymi praktykami, zastosowanie metody partycypacyjnego podejścia naukowego i praktyki otwartej nauki oraz wykorzystanie narzędzia mediów społecznościowych do uzyskania i opisania siedmiu różnych przypadków SBC. Proponujemy nową tabelę macierzową do klasyfikacji anatomicznych typów SBC już opisanych i tych, które jeszcze nie zostały opisane w ogólnodostępnej literaturze.
