Objective: This study aimed to assess the knowledge level of Iranian dental practitioners about digital radiography(DR) andcone-beamcomputedtomography (CBCT). Material and Methods: In this crosssectional study, a researcher-designed questionnaire was administered among 180 general dentists and specialists. The questionnaire had three main domains of demographic information, fifteen questions about knowledge of DR (advantages, disadvantages, physical properties) and twenty six questions about knowledge of CBCT (indications, applications, advantages, route of knowledge acquisition). Data were analyzed using descriptive statistics, t-test and Pearson’s correlation coefficient. Results: Of 180 participants, 76 (42.2%) were females. The minimum, maximum and mean± standard deviation scores obtained in DR were 4, 14, and 9.031 ± 1.85 and in CBCT were 0,26 and 18.56 ± 4.81, respectively. In the CBCT domain, the participants had maximum knowledge about “low radiation dose” (72.8%) and minimum knowledge about the “role of CBCT in determination of bone density” (45%). In DR domain, the participants had maximum knowledge about “no need for radiographic films” (75.6%) and minimum knowledge about “not requiring manual processing” (15.6%). Overall, participants had higher level of knowledge about CBCT than DR. An inverse correlation was noted between age and work experience with the number of correct answers. However, no significant difference was noted in the knowledge level of males and females regarding CBCT or DR (p = 0.233 and p = 0.227, respectively). Conclusions: further education seem imperative for dentists in this respect for more efficient diagnosis and treatment planning, minimize patient radiation dose and save time and cost. Keywords Digital radiography; Cone-Beam computed tomography; Knowledge; Dentists.

La mise en place d’une dent incluse ou retenue, que ce soit chez l’enfant ou l’adulte, est un véritable défi pour le duo de praticiens que sont l’orthodontiste et le praticien en charge de la chirurgie de dégagement. La canine maxillaire est la dent la plus souvent incluse dans le secteur antérieur, avec une prévalence de 2 % dans la population générale. On comprend donc le défi fonctionnel et esthétique de la thérapeutique chirurgico-orthodontique dont l’objectif sera de mettre en place la dent incluse ou retenue sur l’arcade. De nombreuses erreurs devront être évitées pour obtenir un résultat satisfaisant, tant pour le patient que pour son praticien. C’est en faisant un diagnostic précis de la localisation de la dent, grâce à des techniques d’imagerie modernes, que nous pourrons réaliser un acte chirurgical respectueux de la dent concernée et des structures anatomiques qui l’entourent. Les axes et les forces de tractions seront également pensés et réfléchis afin de déplacer la dent jusqu’à sa position finale sur l’arcade dans des conditions optimales. Le contexte parodontal sera optimisé et contrôlé à chaque étape de la prise en charge. En effet, le but étant d’aller au devant de l’apparition des défauts parodontaux, sachant qu’il est plus difficile de tenter leur réparation.

“…Conventionally, multidetector computed tomography (MDCT) data are used to fabricate 3D models and to perform RP. 6 The use of novel imaging modalities such as cone-beam computed tomography (CBCT), with lower equipment costs, lower patient radiation dose, shorter scanning time, and higher image resolution 7 8 9 than traditional imaging techniques, is increasing as a way for presurgical treatment planning to benefit from 3D data. 4 10 …”

Purpose This study aimed to compare the accuracy of 3-dimensional (3D) printed models derived from multidetector computed tomography (MDCT) and cone-beam computed tomography (CBCT) systems with different fields of view (FOVs). Materials and Methods Five human dry mandibles were used to assess the accuracy of reconstructions of anatomical landmarks, bone defects, and intra-socket dimensions by 3D printers. The measurements were made on dry mandibles using a digital caliper (gold standard). The mandibles then underwent MDCT imaging. In addition, CBCT images were obtained using Cranex 3D and NewTom 3G scanners with 2 different FOVs. The images were transferred to two 3D printers, and the digital light processing (DLP) and fused deposition modeling (FDM) techniques were used to fabricate the 3D models, respectively. The same measurements were also made on the fabricated prototypes. The values measured on the 3D models were compared with the actual values, and the differences were analyzed using the paired t-test. Results The landmarks measured on prototypes fabricated using the FDM and DLP techniques based on all 4 imaging systems showed differences from the gold standard. No significant differences were noted between the FDM and DLP techniques. Conclusion The 3D printers were reliable systems for maxillofacial reconstruction. In this study, scanners with smaller voxels had the highest precision, and the DLP printer showed higher accuracy in reconstructing the maxillofacial landmarks. It seemed that 3D reconstructions of the anterior region were overestimated, while the reconstructions of intra-socket dimensions and implant holes were slightly underestimated.
