Full textAbstract:
Unlike patients receiving implants or endodontic treatment, most orthodontic patients are children who are particularly sensitive to ionizing radiation. Cone-beam computed tomography (CBCT) carries risks and benefits in orthodontics. The principal risks and limitations include ionizing radiation, the presence of artifacts, higher cost, limited accessibility, and the need for additional training. However, this imaging modality has several recognized indications in orthodontics, such as the assessment of impacted and ectopic teeth, assessment of pharyngeal airway, assessment of mini-implant sites, evaluation of craniofacial abnormalities, evaluation of sinus anatomy or pathology, evaluation of root resorption, evaluation of the cortical bone plate, and orthognathic surgery planning and evaluation. CBCT is particularly justified when it brings a benefit to the patient or changes the outcome of the treatment when compared with conventional imaging techniques. Therefore, CBCT should be considered for clinical orthodontics for selected patients. Prescription of CBCT requires judicious and sound clinical judgment. The central question of this narrative review article is: when does CBCT add value to the practice of orthodontics? To answer this question, this article presents discussion on radiation dosage of CBCT and other imaging techniques used in orthodontics, limitations of CBCT in orthodontics, justifying the use of CBCT in orthodontics, and the benefits and evidence-based indications of CBCT in orthodontics. This review summarizes the central themes and topics in the literature regarding CBCT in orthodontics and presents ten orthodontic cases in which CBCT proved to be valuable.

Dental X- Rays are important for diagnosing and treating patients by helping to detect oral health issues when they can't be detected by visual or physical examination alone. Dental X-Ray take a much closer look and provide valuable information in the area of interest. Though 2 Dimensional X-Ray and Panoramic radiography can predict diagnosis in number of clinical cases, certain situations demand multiplanar imaging, one such technology is CBCT. CBCT is a specialised 3Dimensional Craniofacial imaging in which 3 Dimensional reconstruction is possible. The final reconstructed image produced, reveals multilayer images in 3 orthogonal planes (coronal, sagittal and transverse) This article focuses on CBCT and its applications in various fields of dentistry.

Full textAbstract:
Cone beam computed tomography (CBCT) is a contemporary, radiological imaging system designed specifically for use on the maxillo-facial skeleton. The system overcomes many of the limitations of conventional radiography by producing undistorted, three-dimensional images of the area under examination. These properties make this form of imaging particularly suitable for use in endodontics. The clinician can obtain an enhanced appreciation of the anatomy being assessed, leading to an improvement in the detection of endodontic disease and resulting in more effective treatment planning. In addition, CBCT operates with a significantly lower effective radiation dose when compared with conventional computed tomography (CT). The purpose of this paper is to review the current literature relating to the limitations and potential applications of CBCT in endodontic practice.

Full textAbstract:
Cone beam computed tomography (CBCT) is becoming increasingly available since its introduction in the late 1990s. The technique provides low-dose high-resolution images of the teeth and jaws. This article discusses the clinical applications of CBCT in children. CBCT is most commonly used in children for localization of teeth and the assessment of root resorption. CBCT can offer an advantage over conventional imaging in selected cases. The decision to image using CBCT should be judged for each individual, and should impact on management and outcome. CPD/Clinical Relevance: CBCT affords low-dose, high-resolution imaging that can be used in appropriately selected paediatric cases.

Dental cone beam computed tomography (CBCT) is the three-dimensional imaging of choice in modern dentistry. In the developed world, guidelines have been published on the use of CBCT in dentistry, largely in response to the risks associated with ionising radiation exposure. However, the availability of different models on the market at affordable prices has made this machine an integral part of the contemporary dentists’ apparatus, even in the developing world. Here, we underline the importance of awareness on radiation protection, image acquisition, familiarity with the software and image interpretation.

Poor medical equipment may lead to misdiagnosis and missed diagnosis by doctors, leading to medical accidents. Given the differences in imaging methods, the performance determination method for conventional computed tomography (CT) does not apply to dental cone-beam computed tomography (CBCT). Therefore, a detection method that is more suitable for the characteristics of dental CBCT and more convenient for on-site operation in hospitals needs to be urgently developed. Hence, this study aimed to design a robust and convenient detection method to control the quality of dental CBCT, grasp the safety information of the equipment in a timely and effective manner, discover and evaluate equipment risks, and take reasonable and necessary countermeasures, thereby, reducing the risk of medical malpractice. This study adopted dose-area product to measure dose parameters and used objective quantitative evaluation methods instead of subjective evaluation methods for spatial resolution, contrast-to-noise ratio index, and uniformity. The dental CBCT of 10 dental hospitals and clinics were tested, and the findings revealed that the testing methods used had good accuracy and applicability.

Research objective. The study aimed to evaluate cone-beam computed tomography (CBCT) capabilities in diagnostics of cystic masses of the jaw.Methods. Over a period of 2015–2016 32 patients age 6 to 67 underwent both panoramic tomography and CBCT (using panoramic tomographic scanner STRATO 2000 and cone-beam computed tomographic scanner i-Cat respectively). 47% (n = 15) of the participants were women, 53% (n = 17) – men. Radiation exposure for a single procedure amounts to 0,05 mSv for panoramic tomography, 0,07 mSv for CBCT (FOV =13 cm), 0,06 mSv for CBCT (FOV =8 cm).Results. Comparative analysis of obtained results demonstrates that CBCT showed 54% (n = 27) more cystic masses of the jaws than panoramic radiography could. CBCT additionally showed the following pathologies: granulomas smaller than4 mm diameter – 85% (n = 23), 83% (n = 23) of said granulomas were found on maxilla, radicular cysts of maxilla – 11% (n = 3), incisive canal cyst – 4% (n = 1). Additionally panoramic tomography analysis misdiagnosed 5 granulomas (80% (n = 4) on mandibular premolar and molar areas) that were not found during CBCT analysis.Conclusion. The low effective dose and high informativity of CBCT enables the method to be used instead of intraoral radiography, panoramic tomography and MSCT as a screening procedure in diagnostics of dento-facial system pathologies, including cystic masses of the jaw.

3D Multislice and Cone-beam computed tomography (CBCT) in forensic odontology has been shown to be useful not only in terms of one or a few of dead bodies but also in multiple fatality incidents. 3D Multislice and Cone-beam computed tomography and digital radiography were demonstrated in a forensic examination form. 3D images of the skull and teeth were analysed and validated for long ante mortem/post mortem intervals. The image acquisition was instantaneous; the images were able to be optically enlarged, measured, superimposed and compared prima vista or using special software and exported as a file. Digital radiology and computer tomography has been shown to be important both in common criminalistics practices and in multiple fatality incidents. Our study demonstrated that CBCT imaging offers less image artifacts, low image reconstruction times, mobility of the unit and considerably lower equipment cost.

Full textAbstract:
In the last few decades, the need for three-dimensional imaging in dentistry has been realized. Because of this, computed tomography, initially applied to medical imaging, started to be used in dentistry. This allowed the dental conditions to be diagnosed with 3D images. But computed tomography was hospital-based, expensive, and resulted in high radiation dose to the patients. In the late 1990’s, a new technology cone beam computed tomography was developed specifically for the dental radiographic imaging. This enables a wider use of 3D imaging for dentists worldwide. This article describes the history of CBCT, fundamentals, position, image intensifiers, field of view, and measurements with CBCT. It also discusses the ethical and legal considerations with CBCT.

Full textAbstract:
Modern treatment in the field of head and neck surgery aims for the least invasive therapy and places great emphasis on restorative treatment, especially in the case of injury and deformation corrective surgery. More and more often, surgeons use CAD/CAM (Computer-Aided Design and Computer-Aided Manufacturing) tools in their daily practice in the form of models, templates, and computer simulations of planning. These tools are based on DICOM (Digital Imaging and Communications in Medicine) files derived from computed tomography. They can be obtained from both fan-beam (FBCT) and cone-beam tomography (CBCT) acquisitions, which are subsequently segmented in order to transform them into a 1-bit 3D model, which is the basis for further CAD processes. Aim: Evaluation of differences in the dimensions of mandible condyle models in fan- versus cone-beam computer tomography for surgical treatment purposes. Methods: 499 healthy condyles were examined in CT-based 3D models of Caucasians aged 8–88 years old. Datasets were obtained from 66 CBCT and 184 FBCT axial image series (in each case, imaging both mandible condyles resulted in the acquisition of 132 condyles from CBCT and 368 condyles from FBCT) and were transformed into three-dimensional models by digital segmentation. Eleven different measurements were performed to obtain information whether there were any differences between FBCT and CBCT models of the same anatomical region. Results: 7 of 11 dimensions were significantly higher in FBCT versus lower in CBCT (p < 0.05).

Full textAbstract:
Cone beam computed tomography (CBCT) is an emerging radiographic imaging modality. The diagnostic benefit must exceed the individual detriment that its generally higher radiation exposure may cause. Since limited studies exist on the use and impact of CBCT in paediatric dentistry, a service evaluation was carried out to explore the reasons for CBCT referral and to identify its impact on the treatment plan and/or management in a paediatric dentistry department. Clinical records for all paediatric patients who underwent a CBCT were reviewed, to identify the reason for referral and its influence on diagnosis or management, by comparing the provisional treatment plan with the definitive treatment plan, post-CBCT. A total of 130 paediatric patients underwent CBCT in a 12-month period, of which 52 satisfied the inclusion criteria. CBCTs were most commonly requested for the localisation of unerupted/impacted teeth 14/52 (27%), assessment of supernumerary teeth 12/52 (23%), and to investigate root resorption 9/52 (17%). All CBCTs provided additional information that assisted treatment planning, diagnosis, or management and, most significantly, 16/52 (31%) of treatment plans were changed based on CBCT findings. All CBCTs requested in this study were justified and confirmed or influenced the management of paediatric patients, ultimately reducing the risk of complications and further treatment.

Objectives: This paper is aimed to report a case of peri-implantitis which is diagnosed using CBCT.
Case Report: A 61 year old male was referred to a dental radiology unit for CBCT examination. The patient complained of pain in the area of the tooth where the implant was attached. CBCT results show there is inflammation around the implant that has been inserted, characterized by a visible radiolucent area in 1/3 of the cervical implant on the mesial, distal, buccal / labial and palatal sides with varying sizes on each side. Based on the radiograph findings, the diagnosis of peri-implantitis was confirmed.
Conclusion: Peri-implantitis is inflammation around the implant which results in a condition in the form of bone loss around the implant that is placed. Radiographic examination such as CBCT can be an excellent choice to help diagnose peri-implantitis by seeing a clearer 3-dimensional radiograph.

Latar belakang: Cone Beam Computed Tomography (CBCT) merupakan salah satu modalitas pencitraan radiologi 3 dimensi yang masih belum optimal digunakan di Indonesia, karena selain mahal harganya juga kemungkinan tingkat pengetahuan dokter gigi tentang CBCT masih kurang. Salah satu penyebab kurangnya pengetahuan bisa jadi karena CBCT tidak termasuk dalam Standar Kompetensi Dokter Gigi Indonesia (SKDGI) sehingga kemungkinan di beberapa Institusi Pendidikan Dokter Gigi (IPDG) tidak banyak diajarkan. Tujuan dilakukan penelitian ini adalah untuk melihat tingkat pengetahuan dokter gigi di Indonesia tentang CBCT. Metode: Desain penelitian deskriptif, data diperoleh menggunakan kuesioner yang ditujukan kepada responden, yaitu dokter gigi di Indonesia yang aktif berpraktik. Data yang didapat lalu diolah menggunakan perangkat lunak Microsoft Excel untuk mendapatkan persentase jawaban dari masing-masing pertanyaan dan disimpulkan apakah mayoritas responden memilih jawaban yang benar atau tidak. Hasil: Hasil menunjukkan pada pertanyaan dengan salah satu pilihan jawaban yang benar, mayoritas responden (lebih dari 50%) menjawab benar. Hal ini menunjukkan bahwa tingkat pengetahuan dokter gigi di Indonesia sudah cukup baik, meskipun masih ada beberapa kekeliruan responden dalam pemahaman tentang CBCT. Kesimpulan: Pengetahuan dokter gigi di Indonesia tentang CBCT berdasarkan penelitian deskriptif sederhana menggunakan kuesioner, menunjukkan bahwa tingkat pengetahuannya sudah cukup baik. Akses informasi di era digital sekarang ini membuat dokter gigi dapat dengan mudahnya memperoleh pengetahuan di luar dari apa yang sudah didapat di pendidikan formal. Perlunya materi tambahan mengenai CBCT di kurikulum pendidikan dokter gigi atau memperbanyak materi tentang CBCT di kegiatan P3KGB dapat menjadi solusi.

Objectives: The aim of this study was to evaluate and summarise features of currently and formerly available cone beam CT (CBCT) devices from 1996 to 2019. Additionally, a recommendation for standardised reporting of CBCT characteristics was provided. Methods and materials: Information about the features of all available CBCT devices was obtained from the manufacturers’ available data. Moreover, site visits to newly developed CBCT machines’ manufacturers were performed in order to obtain relevant information. Results: A total of 279 CBCT models from 47 manufacturers located in 12 countries (Brazil, China, Denmark, Finland, France, Germany, Italy, Japan, Republic of Korea, Slovakia, Thailand, and USA) could be listed. Overall, wide variations in CBCT features and technical specifications were identified. Conclusions: CBCT in dentomaxillofacial radiology is a generic term applicable to a broad range of CBCT machines and features. Experimental outcomes and literature statements regarding radiation doses, imaging performance and diagnostic applicability of dental CBCT cannot be simply transferred from one CBCT model to another considering a wide variation in technical characteristics and clinical diagnostic performance. The information tabulated in the present study will be later provided on the International Association of DentoMaxilloFacial Radiology website ( www.iadmfr.one ).

Background. Cone beam computed tomography (CBCT) has gained widespread acceptance in dentistry for a variety of applications. Most dentists who are not radiologists/trained in radiology are generally not familiar with interpretation of anatomical structures and/or pathosis outside their area of primary interest, as often this was not within the scope of their training.Objectives. To assess that the number of incidental findings on a CBCT scan is high both within and outside of the primary area of interest, thereby emphasizing the importance of interpretation of all areas visualized on the scan.Materials and Methods. An oral and maxillofacial radiologist reviewed 1000 CBCT scans (382 males and 618 females) for findings both in- and outside the area of interest.Results. Of the 1000 subjects that were reviewed, 943 scans showed findings in the primary regions of interest and/or outside the regions of interest, and 76 different conditions were visualized in these scans both in and outside the areas of interest.Conclusion. From the wide scope of findings noted on these scans, it can be concluded that it is essential that a person trained in advanced interpretation techniques in radiology interprets cone beam computed tomography scans.

BACKGROUND Cone beam computed tomography (CBCT) was first introduced in 2008 and has since seen a tremendous growth in both private dental clinics and dental institutions. This has led to the normalization of CBCT use by general dentists. Therefore, it is essential to assess how and why general and specialist dentists use CBCT. The purpose of this study was to assess the knowledge, practice and attitude towards CBCT among general and specialist dentists working in the kingdom of Saudi Arabia. METHODS In this cross-sectional study, a questionnaire was electronically distributed via email and social media from October 2018 to September 2020. The self-administered questionnaire was divided into five segments: demographics, knowledge, current practice, training and attitude. RESULTS A total of 221 dentists filled the questionnaire including 85 general dentists and 135 post graduate students or specialists. The majority of dentists (81.9 %) demonstrated poor knowledge. Orthodontists and endodontists were most aware of CBCT terms. Most dentists (71.5 %) have a CBCT unit in their practice. Only 34.8 % received CBCT training, the majority of which was theoretical. A positive attitude was noted in 83.2 % of dentists by agreeing to a statement regarding CBCT justification. CONCLUSIONS Poor CBCT knowledge was evident in majority of dentists despite having CBCT in their practice. Dentists are highly aware of the importance of CBCT justification and professional interpretation; however, they lack basic knowledge and training related to this imaging modality. This highlights an institutional gap that policy makers should address in order to ensure the highest quality of patient care. KEY WORDS Cone Beam Computed Tomography; CBCT; Survey

Summary Background: The use of cone-beam computed tomography (CBCT), as an additional diagnostic tool in daily dental practice, has expanded rapidly in recent years. Since CBCT allows assessment of dento-maxillofacial structures in three-dimensional manner, its use may be very tempting in alveolar bone furcation defects (FDs) diagnosis. Aim: The aim of this study was to determine the impact of clinical experience and experience with CBCT on FD detection in patients with periodontitis. Material and Methods: Fifteen patients with chronic generalized severe periodontitis were included in the study. In total, 168 furcation sites were analyzed on CBCT images by a previously trained senior year undergraduate student (O1) and a PhD student with three years of CBCT experience (O2), and compared to clinical findings (probing). CBCT images were analyzed on two separate occasions, within a 7-day interval. FDs were assessed both clinically and on CBCT images, using a dichotomous scale (present/absent). Intraobserver agreement for each observer was calculated by using Kappa coefficient (k). Interobserver agreement and agreement between CBCT and clinical findings for both observers were calculated. Results: Kappa coefficient value for both observers indicated a high intraobserver agreement (k1=0.75; k2=0.94). Interobserver agreement of CBCT image analyses was present in 72.6% (73.0% in maxilla, 71.7% in mandible). Agreement between CBCT image analyses and clinical findings for O1 was 48.8% and 51.2% for O2. Conclusion: It can be assumed that clinical experience and CBCT proficiency do not have an impact on FD detection on CBCT images, if an appropriate training was previously performed.

Cone beam computed tomography (CBCT) can be a useful adjunct to conventional plain film radiography, but its use must be carefully justified as the radiation dose is generally higher. Factors affecting the dose include the field of view (FOV) size, the exposure factors, the angle of rotation and voxel size. Once justified, the exposure should be fully optimised to ensure the dose to the patient is kept as low as possible while ensuring there is no reduction in the diagnostic yield. The European Commission (EC) and the Faculty of General Dental Practice (FGDP)(UK) have published selection criteria on the use of CBCT in dentistry. This article provides an overview of CBCT and summarises the latest guidance on selection criteria relevant to the general dental practitioner.

Objectives: The aim of our study was to analyse the utility of the CBCT systems among the dental residents form the Dental University of TarguMures. Material and methods: We conducted an anonymous survey using a questionnaire that included 11 questions. All the 55 participants from all dental specialties studied at the Dental University Center Targu-Mures. The completed questionnaires were collected the results were evaluated and statistically analyzed using chi-square test. Results: Most residents have learnt about the CBCT during the university studied by participating at different radio-imagistic courses outside the curriculum. Only 33 (60%) residents recommend daily a CBCT for supporting their diagnosis most of them being oral surgeons and 7 (12.72%) of them occasionally recommend between 1 and 5 CBCTs a month. Conclusions: The CBCT system used as an imagistic evaluation in all dental specialties is essential and the advantages can be found in the accuracy of establishing a correct diagnosis, creating a treatment plan and results evaluation.

Aim: To evaluate and compare the accuracy of working length determination using Radiovisiography, Cone Beam Computed Tomography and Actual working length of the tooth. Material and Methods: After the access cavity preparation in seventy- two extracted human single rooted teeth, the working length was measured, using Radiovisiography and Cone beam Computed Tomography and its accuracy was compared with the actual working length of the teeth using surgical loupes. Unpaired ‘t’ test was used to test the significance of difference observed in mean working length measurements. Results:. The difference in distribution of readings was found insignificant (p<0.75) by Chi square analysis. The result showed that cone beam computed tomography working length had high percentage of accurate readings as compared to radiographic working length readings. The results also showed high Karl Pearson’s correlation coefficient between the actual working length, radiographic and CBCT working length. Conclusions: Cone beam computed tomography (CBCT) imaging is as accurate and valuable adjunct as the actual working length in determining working length. Clinical Significance: Considering the availability of CBCT and its wide implication in endodontics, there is a need to explore if CBCT can be used as a tool at par with the actual working length determination in endodontics.

ABSTRACT Background The evolution of cone beam computed tomo- graphy three-dimensional (CBCT 3D) imaging has dramatically changed the potential for presurgical and pretreatment planning, such that outcomes are more predictable and complications more avoidable. Purpose The purpose of this article was to systematically review scientific and clinical literature pertaining to the uses and benefits of 3D imaging CBCT for diagnosis and treatment planning in Implantology including prosthodontics. Materials and methods Various databases, like PubMed, EBSCOhost and ScienceDirect, were searched from 1998 to 2010 to retrieve articles regarding the clinical applications of CBCT in dentistry. Cone beam computed tomography in dentistry was used as a key phrase to extract relevant articles in dentistry. A manual search for the references from the retrieved articles was also completed. The articles published only in English, randomized clinical trials, prospective and retrospective clinical studies, laboratory and computer-generated research were included. The search revealed 540 articles of which 447 were irrele- vant to the study and therefore excluded. Results Cone beam computed tomography has created an opportunity for clinicians to acquire the highest quality diagno- stic images with an absorbed dose that is comparable to other dental radiological examinations and less than a conventional CT. Therefore, if placement of an implant might approach a nerve, invade the sinus, or penetrate out of the confines of the jawbone, the patient should be offered a discussion of CBCT 3D imaging. In addition, CBCT 3D patients should be advised of the risks, benefits and alternatives to such treatment, based upon any additional data provided by the imaging.

Objectives: This case report is aimed to describe the features of CBCT in assessing tooth fracture.
Case Report: A 50-year-old man came with complaints of discomfort in the right lower jaw area, especially when used for chewing. The results of the percussion test were positive. CBCT examination showed that there was a radiolucent image of the enamel in the middle of the crown root to the 1/3 apical of the mesial and distal roots of tooth 47 which resembled a fracture line. The fracture line also appears to have reached the pulp. In addition, there is a well-defined radiolucent appearance with an irregular shape along the root from the buccal to lingual alveolar crest and accompanied by a decrease in the alveolar crest. The fracture that occurred in this case was from the enamel to the apical and involved the pulp, thus the radiodiagnosis on tooth 47 was a complicated crown root fracture with lateral periodontal cyst.
Conclusion: CBCT can be used to help identify tooth fractures by obtaining a more accurate and useful value in differentiating conditions associated with fractures. CBCT provides data on the size and length of the fracture line and the size of the lesion.

Cone Beam Computed Tomography (CBCT) has modified the perspective of dentistry images, providing manipulable threedimensional images with a 1:1 patient:image ratio. Treatments and diagnosis are modified or corroborated by CBCT; however, its accuracy in thin structures such as cortical bone has been subjected to critical review. The aim of this study is to correlate the measurement of vestibular alveolar bone height using direct measurements and measurements performed with cone-beam tomographic images with standard (SD) voxel resolution. Thirty incisor and premolar teeth of patients undergoing open curettage were measured with a high-precision caliper and with Cone Beam Computed Tomography (CBCT) at an SD resolution of 0.16 mm voxels in a 3D Orthophos XG Sirona scanner. Intra-observer evaluation was performed using the intraclass correlation coefficient (ICC). Direct measurements and CBCT measurements were correlated using Pearson correlation (PCC). The mean difference between indirect and direct measurements was 3.15 mm. Paired t test and Pearson Correlation coefficient determined that all measurements differed statistically from each other with p<0.05. With the CT scanner and protocol used in this study, CBCT images do not enable accurate evaluation of vestibular alveolar bone height

Cone-beam computed tomography (CBCT) is widely used in maxillofacial surgery. The CBCT image of the dental arches, however, is of insufficient quality to use in digital planning of orthognathic surgery. Several authors have described methods to integrate digital dental casts into CBCT scans, but all reported methods have drawbacks. The aim of this feasibility study is to present a new simplified method to integrate digital dental casts into CBCT scans. In a patient scheduled for orthognathic surgery, titanium markers were glued to the gingiva. Next, a CBCT scan and dental impressions were made. During the impression-taking procedure, the titanium markers were transferred to the impression. The impressions were scanned, and all CBCT datasets were exported in DICOM format. The two datasets were matched, and the dentition derived from the scanned impressions was transferred to the CBCT of the patient. After matching the two datasets, the average distance between the corresponding markers was 0.1 mm. This novel method allows for the integration of digital dental casts into CBCT scans, overcoming problems such as unwanted extra radiation exposure, distortion of soft tissues due to the use of bite jigs, and time-consuming digital data handling.

Aim: The purpose of this study was to compare root canal volumes (RCVs) obtained by means of cone beam computed tomography (CBCT) to those obtained by micro-computed tomography (micro-CT) after applying different segmentation algorithms. Methods: Eighteen extracted human teeth with sound root canals were individually scanned in CBCT and micro-CT using specific acquisition parameters. Two different images segmentation strategies were applied to both acquisition methods (a visual and an automatic threshold). From each segmented tooth, the root canal volume was obtained. A paired t-test was used to identify differences between mean values resulted from the experimental groups and the gold standard. In addition, Pearson correlation coefficients and the agreement among the experimental groups with the gold standard were also calculated. The significance level adopted was 5%. Results: No statistical differences between the segmentation methods (visual and automatic) were observed for micro-CT acquired images. However, significant differences for the two segmentation methods tested were seen when CBCT acquired images were compared with the micro-CT automatic segmentation methods used. In general, an overestimation of the values in the visual method were observed while an underestimation was observed with the automatic segmentation algorithm. Conclusion: Cone beam computed tomography images acquired with parameters used in the present study resulted in low agreement with root canal volumes obtained with a micro-CT tomography gold standard method of RCV calculation.

Introduction: Cone beam computed tomography (CBCT) is a relatively new technological innovation that utilises flat-panel detector technology to obtain CT-like images. The key strength of a CBCT system is that cross-sectional imaging can be obtained using the angiographic flat panel unit without having to move the patient, allowing the radiologist to obtain soft tissue imaging during the procedure. This allows treatment planning, guidance, and assessment of outcome to be performed in one interventional suite. Materials and Methods: From December 2008 to June 2009, 24 CBCT scans were performed during vascular interventional procedures on our department’s newly installed multi-axis flat panel angiographic unit. Results: Ten cases were performed for hepatic trans-arterial chemoembolisation, 9 cases for hepatic arterial Yttrium-90 infusion, while 5 cases were for other indications. CBCT was found to be useful in 20 of the 24 cases. Conclusion: Our early experience showed that CBCT was useful in impacting decisions during selected vascular interventional procedures. As CBCT technology improves, we can foresee wider applications of this technology. Key words: Angiogram, C-arm, CBCT, Embolisation

Endodontic diagnosis and accomplished root canal therapy significantly related to accurate radiographic examination. Currently, intraoral periapical radiography is the first imaging choice of the management of endodontic disease. However, with the development of cone beam computed tomography (CBCT), three-dimensional imaging of the maxillofacial area can be obtained. CBCT allows the more definite diagnosis of periapical pathologies, root fractures, external and internal of root resorptions than 2-dimensional radiographs. However, CBCT imaging is not recommended in every clinical cases due to higher radiation dose than 2-dimensional radiographs. In this review article the aim was to emphasize the clinical implementations of CBCT in endodontics.

Full textAbstract:
Cone-beam computed tomography (CBCT) is an imaging technology that has revolutionised dental imaging in the last decade. Although of particular value to specialists performing implant treatment, it is increasingly being adopted by general dental practitioners. As the radiation dose is higher than that of conventional radiography, it is important to consider its diagnostic efficacy for the common tasks performed in general dental practice, such as caries diagnosis, endodontics and the detection of periapical pathosis. Any new imaging technique needs to have proven advantages over existing techniques before it is adopted, yet the evidence remains quite limited. Furthermore, image quality and radiation doses vary enormously between different manufacturers’ equipment, so that extrapolating results of one piece of research from one CBCT machine to another is fraught with pitfalls. Radiation doses with CBCT are typically an order of magnitude higher than conventional radiography. There is scope, however, for reducing these doses by judicious adjustment of exposure factors and limiting the field of view to the smallest dimensions consistent with the clinical situation. There is still a long way to go before we understand the value of CBCT in dentistry. High quality research evidence is needed, particularly with regard to assessing whether using CBCT improves patient outcomes.

Sectional imaging is a useful tool for the dental practitioner, especially in the fields of oral surgery and implant dentistry. Until recently, the most readily available way to gain three-dimensional information has been computed tomography (CT). The main drawbacks to using this technique have been the substantial dose of ionising radiation and accessibility. Cone-beam computed tomography (CBCT) allows 3D imaging to be made using bespoke equipment designed for the dental practice environment. Exposure to ionising radiation is substantially lower than that for an average x-ray CT scan, but in most cases is still greater than when other dental radiographs are taken. Various guidelines are now in the public domain and these are referenced within this review of CBCT. The concepts of appropriate selection criteria and optimisation of imaging parameters are stressed, along with compliance with the regulations relating to the use of ionising radiation—Ionising Radiation Regulations 1999 and Ionising Radiation (Medical Exposure) Regulations 2000—and training requirements.

OBJECTIVES: The aim of the present study was to compare OPG (orthopantomogram) in locating impacted canines with CBCT (cone beam computed tomography) scans of the same patients. METHODOLOGY: The cross-sectional study was carried out on the OPG (orthopantomogram) and CBCT (Cone-Beam Computed Tomography) of 27 patients (17 females and 10 males) presenting with impacted permanent maxillary canines. Thirty-five impacted canines were subsequently assessed on the four guidelines devised by McSherry and Pitt and applied to the panoramic films and CBCT scans. RESULTS: The results show weak agreement for the canine’s angle to the midline and the canine’s horizontal root apex position (k value=0.55, 0.46, respectively). Moreover, significant differences were found between the OPG (orthopantomogram) and the CBCT (Cone-Beam Computed Tomography) for all the variables using Chi-square and Fisher’s exact test (p=.000) CONCLUSION: The results showed a significant difference in the 2D and 3D images of impacted maxillary canines, which can produce different diagnoses, and therefore treatment plans. OPG (Orthopantomogram) cannot be completely relied upon for the routine diagnosis of impacted canines.

Purpose: We have quantitatively evaluated the image quality of a new commercially available iterative cone-beam computed tomography reconstruction algorithm over standard cone-beam computed tomography image reconstruction results. Methods: This iterative cone-beam computed tomography reconstruction pipeline uses a finite element solver (AcurosCTS)-based scatter correction and a statistical (iterative) reconstruction in addition to a standard kernel-based correction followed by filtered back-projection-based Feldkamp-Davis-Kress cone-beam computed tomography reconstruction. Standard full-fan half-rotation Head, half-fan full-rotation Head, and standard Pelvis cone-beam computed tomography protocols have been investigated to scan a quality assurance phantom via the following image quality metrics: uniformity, HU constancy, spatial resolution, low contrast detection, noise level, and contrast-to-noise ratio. An anthropomorphic head phantom was scanned for verification of noise reduction. Clinical patient image data sets for 5 head/neck patients and 5 prostate patients were qualitatively evaluated. Results: Quality assurance phantom study results showed that relative to filtered back-projection-based cone-beam computed tomography, noise was reduced from 28.8 ± 0.3 HU to a range between 18.3 ± 0.2 and 5.9 ± 0.2 HU for Full-Fan Head scans, from 14.4 ± 0.2 HU to a range between 12.8 ± 0.3 and 5.2 ± 0.3 HU for Half-Fan Head scans, and from 6.2 ± 0.1 HU to a range between 3.8 ± 0.1 and 2.0 ± 0.2 HU for Pelvis scans, with the iterative cone-beam computed tomography algorithm. Spatial resolution was marginally improved while results for uniformity and HU constancy were similar. For the head phantom study, noise was reduced from 43.6 HU to a range between 24.8 and 13.0 HU for a Full-Fan Head and from 35.1 HU to a range between 22.9 and 14.0 HU for a Half-Fan Head scan. The patient data study showed that artifacts due to photon starvation and streak artifacts were all reduced, and image noise in specified target regions were reduced to 62% ± 15% for 10 patients. Conclusion: Noise and contrast-to-noise ratio image quality characteristics were significantly improved using the iterative cone-beam computed tomography reconstruction algorithm relative to the filtered back-projection-based cone-beam computed tomography method. These improvements will enhance the accuracy of cone-beam computed tomography-based image-guided applications.

In order to deeply study oral three-dimensional cone beam computed tomography (CBCT), the diagnosis of oral and facial surgical diseases based on deep learning was studied. The utility model related to a deep learning-based classification algorithm for oral neck and facial surgery diseases (deep diagnosis of oral and maxillofacial diseases, referred to as DDOM) is brought out; in this method, the DDOM algorithm proposed for patient classification, lesion segmentation, and tooth segmentation, respectively, can effectively process the three-dimensional oral CBCT data of patients and carry out patient-level classification. The segmentation results show that the proposed segmentation method can effectively segment the independent teeth in CBCT images, and the vertical magnification error of tooth CBCT images is clear. The average magnification rate was 7.4%. By correcting the equation of R value and CBCT image vertical magnification rate, the magnification error of tooth image length could be reduced from 7.4. According to the CBCT image length of teeth, the distance R from tooth center to FOV center, and the vertical magnification of CBCT image, the data closer to the real tooth size can be obtained, in which the magnification error is reduced to 1.0%. Therefore, it is proved that the 3D oral cone beam electronic computer based on deep learning can effectively assist doctors in three aspects: patient diagnosis, lesion localization, and surgical planning.

The goal of this paper was to review the current literature surrounding the use of cone beam computed tomography (CBCT) related to the diagnosis, prognostic determination, and treatment of periodontal diseases. A literature review was completed to identify peer-reviewed articles related to CBCT and periodontics. The results were filtered to pool only articles specific to CBCT and periodontal diagnosis, prognosis, and treatment/outcomes. The articles were reviewed and findings summarized. Author’s commentary on technological advances and additional potential uses of CBCT in the field of periodontics were included. There is evidence to suggest that CBCT imaging can be more accurate in diagnosing specific periodontal defects (intrabony and furcation defects), and therefore be helpful in the prognostic determination and treatment planning. However, at this time, CBCT cannot be recommended as the standard of care. It is up to the individual clinician to use one’s own judgment as to when the additional information provided by CBCT may be beneficial, while applying the As Low As Reasonably Achievable (ALARA) principle. With continued technological advances in CBCT imaging (higher resolution, reduced imaging artifacts, lower exposure, etc.) the author’s believe that CBCT usage will become more prominent in diagnosis and treatment of periodontal diseases.

Hypoglossal canal (HC) which begins from very slightly above the inner part of the anterolateral portion of the foramen magnum and is located above the occipital condyle of the occipital bone. The aim of this study is to examine HC morphology and variations using cone beam computed tomography (CBCT). The morphology and types of HC were investigated with 303 CBCT images (606 side). Type 1 variation in 606 HC examined becomes the most commonly observed type (57.3%) while type 5 variation was the least common type of variation (0.8%). Type 1 HC was statistically higher in males (p=0.004). Because of HC, which is an anthropologically important point and enters the field of images in CBCT scan, it is recommended that dental radiologists should be aware of their variations and be wary of the pathologies that may occur in this region.

In this period of advanced technology, cone beam computed tomography (CBCT) was embraced into the dental settings very rapidly and has gained popularity in the field of oral radiology due to its advantages over conventional two-dimensional (2D) radiography, such as its relatively compact size, low cost, low ionizing radiation exposure when compared to multi detector computed tomography (MDCT). This paper provides an overview of the basic principles of CBCT technology and reviews its current advances on the specific application to the oral and maxillofacial region.
