    Opis:
    Introduction: The aim of the study was to prove that a combination of visual surgical planning (VSP) and cone beam computed tomography (CBCT) is an optimal technique in fibular free flap reconstructions after complex tumor resections in the head and neck region and that it leads to better functional and aesthetic outcomes. Material and method: Six patients (3 females, 3 males) with head and neck tumors were included in the study. The region concerned midface in 2 cases and mandible in 4 patients. On the basis of computed tomography of the head, fibular free flap (FFF) reconstruction was planned with the VSP technique. The 3D-printed models were prepared. At the beginning of the operation and a few minutes after the reconstruction, an xCAT CBCT by XORAN was performed. Minor corrections of the angles of the reconstructed bony parts were made where needed. The time of the operation was assessed for each case. Functional and cosmetic results were evaluated in a 1-year follow-up. Results: The mean time of operation was 6 hours and 48 minutes, which was approximately 1hour and 40 minutes less than standard reconstructive surgery. Functional recovery was achieved in all patients. Aesthetic result was unsatisfactory for 2 patients due to insufficient soft tissue masses of FFF. Conclusions: The authors claim that intraoperative CBCT imaging, regardless of the cost, improves the accuracy of aesthetic outcome of reconstructive surgeries based on VSP, especially in the region of the midface and the mandible. Further studies on a higher number of subjects are required.

    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.

    Purpose: The purpose of this study is to present the author's method of planning the procedure of immediate implant-prosthetic restoration in place of a tooth qualified for removal by performing a surgical template and implant-prosthetic restoration based on data obtained in the CBCT test and intraoral scanning 3D model. Design/methodology/approach: The method of planning the implant surgery through the design and manufacture of surgical templates and implant prostheses performed before the start of medical procedures was described on the basis of actual clinical data from patients with anterior segment teeth qualified for extraction for reasons of complications after endodontic treatment. The placement of the implant was planned using virtual reality, where the bone model and the virtual soft tissue model were combined, which made it possible to perform a surgical template and prosthetic implant restoration. For the manufacturing, 3D printing as stereolithography SLA and selective laser sintering SLS for the surgical template manufacturing and CNC milling in the case of the prosthetic implant were used for restoration. Findings: The method allows planning the implant position based on two connected bone and soft tissue models and allows to design and manufacture a surgical guide. In this way, it becomes possible to place implants in the patient's bone during surgery procedure in the planned position and to install the prosthetic implant restoration in the form of an individual abutment and a PMMA crown during the same procedure in the surgical part. Practical implications: Thanks to the method of computer-aided design/manufacturing CAD/CAM production of surgical templates and prosthetic restoration based only on digital models and the planned position of the implant, it is possible to carry out the procedure of immediate tooth extraction and replacement with permanent prosthetic restoration. The whole process is based on the CBCT test performed at the beginning. The presented method allows shortening the procedure time by four times and the rehabilitation time by 3-6 months when performing the procedure in a minimally invasive manner. Originality/value: This article presents the original design and production method of surgical guides. It allows for precise planning of the implant position and transfer of this data to the patient's mouth during the procedure, enabling permanent prosthetic restoration before starting medical procedures.

    taurodontic teeth
    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.

    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.

    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.

    Purpose: The paper describes tests of CBCT cone beam scanners carried out to ensure projection quality. Design/methodology/approach: During the studies, phantoms were scanned with a leading brand volumetric CT scanner according to the device manufacturer's recommendations. The water phantom and phantom made of PMMA with materials of different radiological densities were used in the performed tests. The image area during the tests was determined as a cylinder with diameter of 80 mm and height of 90 mm. In turn, exposure parameters were selected on the basis of clinically applied protocols of cranial imaging. Within carried out research, tests of noise level were performed, image homogeneity was analysed and Hounsfield units constancy was determined. To this end, 18 quality control tests were analysed, which were performed at intervals of about 30 days. Images obtained during phantom scans were analysed by determining the Hounsfield value of selected areas and their changes over time. Findings: The analysis of all carried out projection quality control tests showed that they met the criteria set by the manufacturer, falling within the predefined value ranges. One of the performed tests presented results approaching the limit of acceptable values. After notifying this case, it was shown that the CT scanner was serviced during that period. The obtained results of the quality control tests of water phantom as well as of the material phantom imaging were maintained at similar levels after the service activities. No changes were observed in the obtained mean values of Hounsfield units, which would indicate a decrease in diagnostic quality of CBCT projections. Research limitations/implications: The results presented in this publication require further analysis. These should be complemented by incl. analyses of spatial resolution and image geometry. Practical implications: Carried out research has shown that cyclical quality control testing by a qualified operator is an essential activity to ensure high diagnostic quality of the device. In addition, this analysis showed that procedures of in-service tests should not be omitted and delayed. Originality/value: Originality in these tests is the possibility to improve the procedures for performing basic quality control tests.

    Introduction and aim. This study aims to estimate the age of a population in Central India by analyzing the mental foramen using cone beam computed tomography (CBCT). The objectives of the study are to determine the parameters for age determination and study bilateral variations in mental foramen dimensions using CBCT. Material and methods. One hundred and twenty CBCT scans, HD LED monitor, GALAXIS GALLIEOS viewer. Results. Results from the study show significant values for various parameters such as the upper and lower borders of the mandible and mental foramen. Bilateral variations were also observed. The age regression model indicates a significant correlation between estimated and original ages for individuals aged between 31 to 50 years. While the study only analyzed five parameters of the mental foramen, it suggests that a more comprehensive assessment of mental foramen parameters with a larger sample size can yield more definitive results for age determination. Conclusion. As only five parameters of mental foramen had been assessed in this retrospective study, so a comprehensive assessment of various other parameters of mental foramen with an increased sample size may be done for more definitive results for gender and age determination.

    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.

    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.
