A Questionnaire Cross-Sectional Study on Application of CBCT in Dental Postgraduate Students
Abstract
Background:
CBCT is a new emerging imaging technique which uses a cone-shaped radiation beam that is centered on a 2D detector. It is now routinely evaluated for oral and para-oral disorders. It has been widely accepted in practice in radiology in academic and hospital settings and included in the curricula of some countries. The present study aimed to evaluate the awareness of and knowledge on CBCT among postgraduates.
Material/methods:
After obtaining permission and ethical clearance from concerned authorities, an anonymous survey on CBCT was conducted in a dental college by using a close-ended validated questionnaire to get to know the knowledge on CBCT among postgraduates in a dental college in India.
Results:
A total of 100 volunteers participated but only 88 postgraduates responded to the questionnaire. Among the respondents, 54.5% were not using CBCT for diagnostic purposes at their work place. A total of 68.2% of respondents were partially aware of common terminologies used in CBCT. Most of the respondents were unsure about radiation exposure of CBCT when compared to other types of imaging. Almost nobody had any idea on relative importance of image characteristics. Only half of the respondents were willing to attend a hands-on course on CBCT interpretations versus pathology.
Conclusions:
In the present study it was apparent that most of the respondents were lacking adequate knowledge on CBCT. Hence, there is an urgent need for more training programs on CBCT which would result in better diagnosis and treatment planning.

... However, only 37.5% of the respondents reported full knowledge of the terminologies used in this imaging examination, such as Voxel, FOV, multiplanar reconstructions and DICOM images. Thus, we infer that the lack of knowledge of the terminology, such as Voxel and FOV, leads students and professionals of Pediatric Dentistry to unintentionally disregard a request for specific protocols that might provide proper protection for the infant patient (LAVANYA et al., 2016) A study by Lavanya et al. (2016) found that most of the respondents felt the need for CBCT in dentistry to investigate the following specific cases: relation of third molar roots and the mandibular canal, mandibular and maxillary fractures, placement of dental implants, sinuses disorders, cysts and tumors, TMJ pathologies, and orthognathic surgeries. In the present study, most respondents were unaware of the equivalence of the CBCT exposure doses (small, medium and large FOV) compared to other imaging techniques, such as intraoral radiography, PR, and FBCT. ...

This study aimed to evaluate the knowledge level of Dentistry students, who have already taken the Dental Radiology and Maternal Child 1 courses at the University of Caxias do Sul in May 2020, on the appropriate prescriptions and protocols of different imaging exams in their daily clinical practice. Materials and Methods: A questionnaire was developed using the Google Forms online platform and divided into different sessions: a) personal information; b) prescription of CBCT; c) students' specific knowledge regarding CBCT images; d) prescription of dental radiography techniques; e) imaging diagnostics; f) exposure dose; g) care with the radiation protection of both the professional and the patient during processing time for conventional radiographs. Fifty-six participants received the form by email. Results: Regarding CBCT, 66.6% of the respondents have already used it, and 91.6% believe that it is essential to have easy access to this technology. Whereas 37.5% declared thorough knowledge of the main terminologies, 66.67% stated that they rarely prescribe CBCT. Regarding radiation protection, 97.92% of the respondents said they wear a lead apron to ensure patients' protection; however, 23% of the aprons do not include a thyroid gland shield. As for the sensitivity of radiographic films, 50% of the respondents use radiographic film F. Conclusion:Thus, we found that a lack of specific knowledge on CBCT examinations and on conventional radiographic films exists among dental surgeo.
... [7,8] CBCT was first introduced in 1982 for angiographic purpose by Robles R.A. Mozzo et al and Arai et al independently introduced CBCT for Dental and Maxillofacial applications. [6,12,14] It is easily available in urban and suburban setups because of which diagnosis, evaluation of severity of disease, treatment planning, administration and follow up have become easy. [1,7,8,9] Revolution is evident in Dental and Maxillofacial imaging by Cone Beam Computed Tomography. ...
... Cone Beam Computed Tomography (CBCT) imaging represents the most important technological progress in maxillofacial imaging since the advent of orthopantomography. [2,14] Initially, CBCT was utilized by cardiothoracic surgeons for angiographic applications, but they eventually discontinued its use with the emergence of multidetector CT. The technology was then adopted by dentists for imaging the maxillofacial region in the late 1990s. ...
Background: Cone Beam Computed Tomography (CBCT) is an advanced imaging device that allows in diagnosing hard tissue lesions of oral and maxillofacial location. Aim: To assess the knowledge and focus on various application elements of CBCT and also to set up the importance of dental student’s attitudes closer to new technologies utilized in dental practice among undergraduate college students of Rishiraj College of Dental Sciences and Research Centre, Bhopal. Strategies: Self-administered E-questionnaire inclusive of 12 questions distributed amongst 213 dental students of Rishiraj College of Dental Sciences and Research Centre. Results: It was observed through the survey that there were varied responses from the students of B.D.S 1st, 2nd, 3rd, 4th year and Interns, but most of students were quite aware about CBCT.
... CBCT also enabled more precise localization of pathologies (P < 0.05). However, no statistically significant difference was observed in the overall presence of pathology diagnoses [11]. ...
... Our findings contradict a cross-sectional questionnaire study by Reddy Lavanya in 2016 on the use of CBCT among third-year dental students, which found that a majority lacked knowledge of CBCT image characteristics. This knowledge gap was often attributed to the absence of CBCT units in their workplace, lack of practical experience, and unfamiliarity with image acquisition characteristics [11]. ...
... The authors of this systematic review conducted a comparative analysis (Table 3) to assist general dentists in determining when to request imaging studies for pregnant patients. 33,34 Table 3 provides the average effective dose values for each imaging examination. For intraoral radiography (full mouth), D-speed film had an associated dose of 388 μSv, F-speed/PSP film a dose of 171 μSv, and CCD sensor imaging a dose of 85 μSv. ...
Purpose
This study was conducted to investigate the safety of dental imaging in pregnant women with respect to fetal health.
Materials and Methods
Searches were conducted of the PubMed, Scopus, and Web of Science databases in May 2023. The inclusion criteria encompassed cross-sectional and longitudinal studies that focused on the analysis of diagnostic dental imaging in pregnant women, as well as studies utilizing phantoms to simulate imaging examinations. The exclusion criteria consisted of reviews, letters to the editor, book chapters, and abstracts from scientific conferences and seminars.
Results
A total of 3,913 articles were identified. Based on a review of the titles and abstracts, 3,892 articles were excluded, leaving 21 articles remaining for full-text review. Of these, 18 were excluded, and 4 additional articles were included as cross-references. Ultimately, 7 articles underwent quantitative-qualitative analysis. Three retrospective studies were focused on pregnant women who underwent dental imaging procedures. The remaining 4 studies utilized female phantoms to simulate imaging examinations and represent the radiation doses absorbed by the uterus or thyroid.
Conclusion
Few dental radiology studies have been conducted to determine the safe radiation threshold for pregnant women. Additionally, the reviewed articles did not provide numbers of dental examinations, by type, corresponding to this dose. Dental imaging examinations of pregnant women should not be restricted if clinically indicated. Ultimately, practitioners must be able to justify the examination and should adhere to the “as low as diagnostically acceptable, being indication-oriented and patient-specific” (ALADAIP) principle of radioprotection.
... 9 In addition to periapical, interproximal, and/or panoramic radiographs, cone beam computed tomography (CBCT) has come out to improve diagnosis in dentistry, and it is also available as an additional examination option. 10 CBCT features threedimensional imaging, where it is possible to evaluate certain structures through three different planes and, based on this, propose an individualized and more precise treatment plan. 11 As for the chosen therapy, the positioning of the dental organ and the Nolla stage define the most indicated approach. ...
The aim of the present work is to report a surgical approach as a therapy for teeth with late eruption. Patient 11 years old, female, feoderm, attended the dental clinic of Universidade Nilton Lins accompanied by her mother, presenting as main complaint discomfort when chewing on the right side. The clinical examination revealed the absence of deciduous teeth, thus characterizing the end of the denture transition period, extensive carious lesion on tooth 36 and increase in gingival volume preventing the eruption of the crown of tooth 25. Given the clinical condition, the proposed treatment plan was the indication of endodontic therapy of tooth 36, followed by ulectomy of tooth 25. respective procedures, obtaining an immediate satisfactory result with the appearance of the clinical crown. After the 15 day follow up period, the patient returned where the scar tissue and the tooth's adequacy to the underlying structures were highlighted. Therefore, through the postoperative follow up, a satisfactory surgical intervention can be evidenced, meeting the expected expectations, returning the reported teeth to their specific functions
... Only a few studies with similar objectives can be found in the literature. Most of the published survey studies focus on the practice of CBCT use among dentists [16][17][18]. For Switzerland, guidelines for the use of CBCT have been published in 2014 [19]. ...
Objectives
To retrospectively evaluate all cone-beam computed tomography (CBCT) scans acquired from 2017 to 2022 in a Swiss university dental clinic with particular emphasis on radiation protection aspects.
Material and methods
Radiological databases at the dental clinic of the University of Bern, Switzerland, were explored using a self-developed search algorithm. Data of all acquired CBCT from 01.01.2017 to 27.06.2022 were screened. Exposure parameters (exposure time, exposure angle, milliampere (mA), kilovoltage (kV), field of view (FOV) size), dose area product (DAP), age, and sex of the patient were recorded anonymously. The collected data were analyzed mainly descriptively. Correlations measured the statistical relationships between the variables.
Results
A total of 10,348 CBCT datasets were analyzed. Patient age ranged from 5 to 96 years (mean: 49.4 years, SD: 21.6 years). The number of CBCTs in patients under 25 years was around 20% each year. In total, 10,313 (99.7%) CBCTs were acquired in small to medium FOV (FOV up to 10 cm of height), and 35 (0.3%) in large FOV (height > 10 cm). DAPs of small FOVs were 518.3 ± 233.2 mGycm² (mean ± SD), of medium FOV 1233 ± 502.2 mGycm², and of large FOV 2189 ± 368.7 mGycm². DAP (ρ = 0.4048, p < 0.0001) and kV (ρ = 0.0210, p = 0.0327) correlated positively with age. Reduced scan angle correlated with young age (rpb 0.2729, p < 0.001). mA did not correlate with age (p = 0.3685).
Conclusions
This study demonstrates that certain well-known radiation protection aspects as the reduction of FOV, mA, kV, and scan angle were only partly considered.
Clinical relevance
Known radiation protection aspects, especially in young patients, should be fully applied in regular clinical practice.
... correctly answered the questions related to CBCT knowledge, which reflects good level of knowledge among Jordanian and Polish dental interns and is in line with few studies conducted in India, Turkey, Iran, and Middle East [6][7][8][9]. In other previous studies [3][4][5][10][11][12][13][14][15], the level of knowledge among dentists, interns, and specialists was inadequate and varying depending on several factors, such as age, years of experience, and specialty. Although all participants were non-specialist, they were young graduates, which can explain the good level of knowledge among them. ...

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.
... About 72% of the participants were not aware of the basic terminologies used in CBCT, owing to the fact that not sufficient knowledge is attained during the BDS course. Similar to this proportion are the conclusions drawn by Lavanya R et al. [11] , in a cross sectional study, where only 68.2% had partially awareness of the same. However, after conducting the seminar in this survey, there was an increase of knowledge by about 45%. ...
Objective
Evaluating the level of knowledge and applicative knowledge regarding Cone Beam Computer Tomography (CBCT) among interns from various dental institutes in the country.
Materials and Methods
A Questionnaire with 15 close-ended questions was circulated to 2000 interns from various dental institutes across India. 1154 interns participated in the study. The response rate was 94.8%.
Results
The majority of the interns (48.6%) gained knowledge regarding CBCT from lectures and faculty seminars while 15.3% through conferences. The maximum knowledge mean score was noted from the central zone (7.66 ± 3.8). Demographic variables did not show any signs of the impact of technical knowledge on the applicative knowledge of the study population.
Conclusion
This study suggests CBCT be a definitive 3D imaging technology in the maxilla-facial region and awareness regarding the same needs to be increased. There is a need to include CBCT-based information in the undergraduate curriculum to improve knowledge levels.

Aims and objectives:
To conduct a survey of the current radiographic prescription practices among implant practitioners in the state of Kerala, India.
Methods:
300 dentists were interviewed by employing a questionnaire which enquired about the radiographic evaluation methods prescribed by practitioners in implant site assessment in their implantology practice. Other reasons for choosing particular imaging modalities were also enquired. The data collected from the survey was analysed using Epi-Info 7.1.3 software.
Results:
Around 87.33% of the dentists prescribed only OPG for the implant site assessment and only 4.66% ordered Orthopantomograph (OPG) in combination with an Intra Oral Periapical Radiograph (IOPAR) and 4.33% ordered OPG with Computed Tomography (CT). Only 0.02% of the practitioners ordered CT as a single examination and 1% ordered it in conjunction with other modalities. 0.066% individuals ordered IOPAR as the sole imaging modality and none of them ever prescribed conventional or Cone beam computed tomography.
Conclusions:
Our study has conclusively proven that most of the dentists prescribe OPG followed by a combination of OPG and Intraoral periapical radiographs in their implant practices. Many of them were not aware and did not follow the American Academy of Oral and Maxillofacial Radiology, European Academy of Dentomaxillofacial Radiology, European Association of Osseointegration and International Congress of Oral Implantology recommendations regarding cross-sectional imaging.
Introduction:
The aim of this study was to assess the knowledge and attitudes of Turkish endodontists toward digital radiological imaging (DRI) and cone-beam computed tomography (CBCT).
Materials and methods:
One hundred and fifty questionnaires were distributed. Questionnaires were given to a sample of endodontists and PhD students in endodontics who attended the 11 th International Congress of the Turkish Endodontic Society in Istanbul in 2012. Following the congress, the same questionnaires were sent electronically to endodontists who did not attend the congress. The participants were asked to answer 28 multiple-choice questions concerning their knowledge and practice regarding recent imaging techniques. The questions were subdivided into 2 main topics; general information; general approach to digital imaging. The statistical analysis was carried out by an χ2-test to compare the means at a significance level of P < 0.05.
Results:
The response rate for this study was 74%. The mean age of the endodontists who participated in this study was 32.74 ± 10.40 (range 22-61 years). Of the endodontists, 76.6% used digital imaging techniques (DUEs) in their clinics. Statistically significant differences were found between the DUEs and endodontists not using digital imaging (NDUEs), regarding age, gender, graduation year and place of employment ( P < 0.01). Endodontists 40-years-old and above had significantly lower knowledge of CBCT compared to the younger groups ( P = 0.001).
Conclusions:
The number of endodontists using digital imaging has been increasing in Turkey. The findings of the present study highlighted the need for adapting to new technologies via continuing education.
After over one decade development, cone beam computed tomography (CBCT) has been widely accepted for clinical application in almost every field of dentistry. Meanwhile, the radiation dose of CBCT to patient has also caused broad concern. According to the literature, the effective radiation doses of CBCTs in nowadays market fall into a considerably wide range that is from 19 µSv to 1073 µSv and closely related to the imaging detector, field of view, and voxel sizes used for scanning. To deeply understand the potential risk from CBCT, this report also reviewed the effective doses from literatures on intra-oral radiograph, panoramic radiograph, lateral and posteroanterior cephalometric radiograph, multi-slice CT, and so on. The protection effect of thyroid collar and leaded glasses were also reviewed.
Cone beam computed tomography (CBCT) is an excellent three-dimensional (3D) imaging modality. Traditional dental education has focused on teaching conventional (2D) imaging. The aims of this survey-based study were therefore to evaluate the incorporation of CBCT teaching in both the predoctoral/undergraduate (D.D.S./D.M.D./B.D.S.) and postgraduate/residency specialty training curricula in dental schools in the United States, the United Kingdom, and Australia. A nine-question survey form was electronically mailed to fifty-seven schools in the United States, sixteen schools in the United Kingdom, and seven schools in Australia. Fifty U.S. dental schools (89 percent), ten U.K. dental schools (62.5 percent), and one Australian dental school (14 percent) presently have CBCT equipment. The majority of responding schools do not include instruction in higher level use of this technology for undergraduate/predoctoral students, raising questions as to whether these students are adequately trained on qualification. Larger numbers of schools reported providing this training to residents in specialty programs. A similar trend was noticed in U.S., British, and Australian dental education. If general dentists are to be permitted to purchase and use CBCT equipment, inclusion of CBCT in dental education is an absolute requirement to prepare future dental practitioners to apply 3D imaging appropriately for diagnosis and treatment planning.
This article reviews the various clinical applications of cone-beam computed tomography (CBCT). A literature search was conducted via PubMed for publications related to dental applications of CBCT published between January 1998 and June 15, 2010. The search revealed a total of 540 articles, 129 of which were clinically relevant and analyzed in detail. A literature review demonstrated that CBCT has been utilized for oral and maxillofacial surgery, endodontics, implantology, orthodontics, temporomandibular joint dysfunction, periodontics, and restorative and forensic dentistry. This literature review showed that the different indications for CBCT are governed by the needs of the specific dental discipline and the type of procedure performed.
Objectives: The present study was carried out to assess the awareness and knowledge of CBCT among practicing general dentists. Materials and methods: A 13 multiple choice questionnaire was given to practicing general dentists to answer. A total of 50 dentists participated in the survey (21 females and 29 males). Results: Among 50 dentists, about 82% (n=41) are aware of cone beam computed tomography used for dentomaxillofacial region and 18% (n=9) are not aware of cone beam computed tomography used for dentomaxillofacial region. out of 41 dentists about 48% got to know about CBCT through lectures and class , 12% through internet, 9.7% through journal, 17% through seminars, 7.3% during PG, 2.4% during trauma case referral and 2.4% through advertisement. Among 41 dentists about 39% attended workshops regarding CBCT and 61% did not attend any workshops. About 80.48% felt that lower radiation is the most advantage of CBCT over CT. About 87.8% answered that CBCT offers enhanced diagnosis at lower dose than CT and 7.32% contradicted this and 4.88% have no idea. About 14.63% felt that less radiation is the primary difference between CT and CBCT, 14.63% felt shape of the beam, 2.44% cost, and 2.44% quality and precision and 65.85% have no idea. About 70.73% reported that the radiation risk from CBCT is generally higher than conventional CT scans, 9.76% contradicted this and 19.51% have no idea. About 68.29% have referred their patients for CBCT while 31.71% have not referred. 2.44% guessed the cost to be less than Rs 500, 26.83% between Rs 500 – 1000, 17.07% above Rs. 1000 and 53.66% having no idea. About 48.78% reported they would choose CBCT for implant, 35% for implant and evaluation of cyst and tumors, 19.51% for all the mentioned cases. About 43.90% believed that CBCT would be used in the near future in all areas of dentistry, 7.32% believed that it will not be commonly used in routine practice and 12.2% have no idea. 39.02% thought that it is necessary for CBCT to be available at their speciality,56.1% did not think as necessary and 4.88% have no idea. Majority of the participants thought that clinical phase should include lectures on CBCT, 14.63% and 17.07% on pre clinical and doctoral phase respectively. Majority of the participants about 95.12% are satisfied with the use of CBCT while 4.88% are not satisfied. Conclusion: the present study shows better awareness of CBCT among dental practitioners and this study suggests that more knowledge should be gained on this emerging new technology for better diagnosis and treatment planning
Objective
Cone-beam computed tomography (CBCT) is making inroads into dental practice worldwide, both in terms of adding the third dimension to diagnosis, and also in terms of enabling image-guided treatment strategies. This article reports trends in the early referral pattern of patients to a CBCT facility in the United States.
Methods
With institutional review board approval, a retrospective study was made of sequential CBCT radiographic reports made by a specialist oral and maxillofacial radiology service from May 2004 through January 2006 (n = 329). Demographic and referral data were extracted from the reports. Descriptive statistics identified referral patterns, trends, and indications for CBCT. Comparisons were made with the Rogers' Product Innovation Adoption curve.
Results
The mean age of referred patients was 45 ± 21 years, and there was a predominance of women (62%). Oral and maxillofacial surgeons (51%) and periodontology specialists (17%) made most patient referrals. The listed reasons for CBCT referrals were dental implant planning (40%), suspected surgical pathology (24%), and temporomandibular joint analysis (16%). Other uses included planning extraction of impacted teeth and orthodontic assessment. Over the period of the study, the numbers of pathology diagnosis cases remained relatively constant, while adoption of CBCT for dental implant planning followed closely the first three stages of the Rogers' Product Innovation Adoption curve. Alongside this increased CBCT adoption for dental implant planning, there was an associated increased demand for use of DICOM image sets for laser modeling and provision of surgical guides.
Conclusions
Diagnosis will probably remain a constant source of referral for CBCT examination by oral and maxillofacial radiologists. Nevertheless, more specialized applications such as laser-guided model fabrication and image-guided surgery are expanding indications for CBCT referrals by dentists and also expanding the horizons of clinical dental practice.
Objective: The authors have developed a clinical model of limited cone-beam X-ray CT for dental use and started to use the model in clinical practice. It is called “3DX multi image micro CT” (3DX, J. Morita, Kyoto, Japan). Presented here is a report about the result. Method: We made a design of limited cone-beam X-ray CT so that it could be most effective for dentistry use. This machine is a kind of cone-beam type X-ray CT equipped with a 4-in. imaging intensifier (II) as a sensor. The size of the X-ray at its rotational center is 29 mm high and 39 mm wide. While a subject is seated for shooting, a focal spot and the X-ray rotational center are put into agreement with a light beam of X, Y and Z directions. Images are taken under the exposure condition of 80 kV (X-ray tube voltage) and 2 mA (X-ray tube electric current). Exposure time is 17 s, during which 512 frames of two-dimensional images are recorded. These images are reconstructed with a personal computer into digital images in a columnar field of 38 mm in diameter and 29 mm in height. It takes about 10 min to carry out arithmetic calculation for the image reconstruction. Clinical use of this machine started in January 2001 at the Department of Radiology, Nihon University of Dental Hospital. Result: The 3DX produced highly clear, three-dimensional tomographic images of impacted teeth. Conclusion: Since the 3DX is capable of producing clear images with a small radiation dose, we consider it to be effective as a tool to support three-dimensional imaging diagnosis for dental implants, impacted teeth, etc.
