... However, a number of researchers argue that patients are not at all at danger of radiation damage from imaging tests that use modest radiation doses, including intraoral radiography [44,45] . Therefore, in order to minimise negative effects on the developing child, regulations indicating the maximum safe dosage levels and the related limitations on the frequency of dental treatments for imaging for pregnant women must be put in place [46] . The amount of radiation that pregnant women are exposed to during full-mouth periapical examination using traditional film radiographs and digital radiography. ...
... The amount of radiation that pregnant women are exposed to during full-mouth periapical examination using traditional film radiographs and digital radiography. They characterised this dose as low, stating that it is [45,46] comparable to about three hours of ambient radiation when taking into account the radiation that enters the uterus directly. Researchers discovered no discernible variation in uterine radiation dose between lead-shielded and non-shielded subjects. ...
... Regulations defining the kinds of X-ray machines that are available on each continent and the proper radiation dosages for certain dental diagnostics, such as intraoral and panoramic radiography and CBCT, are dependable for dental professionals across the globe. These guidelines support the As Low as Diagnostically Acceptable (ALADA) principle, which promotes the use of the lowest radiation dose feasible while still getting an image resolution sufficient for an appropriate assessment, and they cover the regulatory requirements for all dental specialties [46,47] . ...
... KIBT'nin diş hekimliğinin farklı disiplinlerindeki kullanımı için gerekli temel ilkeleri ve endikasyonları kapsayan kılavuzların varlığına rağmen, diş hekimlerinin KIBT ile ilgili bilgi düzeylerini inceleyen çalışmaların çoğunda katılımcıların bu görüntüleme yöntemi ile ilgili yeterli bilgiye sahip olmadıkları saptanmıştır. [7][8][9][10][11][12][13][14][15] Literatürde hekimlerin KIBT ile ilgili bilgi düzeylerini değerlendiren çalışmalar incelendiğinde; çok sayıda araştırmanın serbest diş hekimleri ile gerçekleştirildiği göze çarparken 10,11,13,16,17 , daha az sayıda araştırmada da diş hekimliği eğitimi alan lisans ve lisans üstü öğrenciler çalışmaya dahil edilmiştir.

... Computed Tomography (CT), a high-quality 3D imaging technology that has become widely prevalent in dental practice since its development in 1972 and is now recommended before various procedures for visualization of dental hard tissues as well as osseous structures in the oral cavity including dental pathologies. [8] Though intraoral radiographs remains gold standard radiographic diagnostic tool that aid in detection of dental pathologies, these images does not provide complete and superior in-depth details as compared with CBCT/CT that delivers three-dimensional diagnosis and treatment planning information with a wide range of clinical applications. ...
... In the present study majority of the dental students (86.4%) were familiar with the term CBCT and CT among which 40% and 35.5% gained more knowledge/Information about CBCT and CT through lectures and by attending seminars/CDE/Workshops (75.5%) respectively which was consistent with the studies conducted by Mahabob MN et al [1] , Kamburoglu K et al [12] and Gunasekaran S et al [2] among which 67.1% prefer CBCT and only 17.4% opted CT for 3D imaging of head and neck region which was relatively higher than other studies carried out by Gunasekaran S et al [2] , Lavanya R et al [8] and Almohiy H et al. [11] More than half of the dental students (51.6%) recommended CBCT and CT should be a part of dental curriculum and education in final year and 30.3% recommended CBCT and CT as a part of third year (BDS) dental curriculum to gain adequate theoretical knowledge which was similar to the results by Kamburoglu K et al [12] , Gunasekaran S et al [2] , and Lavanya R et al.

Background: Cone Beam Computed Tomography (CBCT) and
Computed Tomography (CT) is an advanced imaging device that helps
in diagnosing hard tissue lesions of oral and maxillofacial region. Aim:
To assess the knowledge and awareness on various application aspects
of CBCT and CT and also to establish the importance of dental
student’s attitudes towards new technologies used in dental practice
among undergraduate and post-graduates students of Rama Dental
College Hospital & Research Centre, Kanpur. Methods: A validated,
pretested, and self-administered questionnaire consisting of 15 close-ended questions was distributed among 227 dental students of Rama
University. Results: Among the 227 participants, the proportion of
participant’s awareness regarding CBCT and CT usage according to
their educational status in third year, final year, interns, and postgraduate students (PGs) were found to be 80.6%, 90.9%, 89.9%, and 100%, respectively.
This data revealed that a significant proportion of PGs had more awareness of CBCT and CT use for imaging of maxillofacial region as compared to undergraduates. Conclusion: It was observed in the survey that undergraduate students had less knowledge about CBCT and CT as compared to post graduates who need to upgrade their knowledge to enhance their dental practice. This observation undoubtedly necessitates the need for inclusion of new technologies in the oral radiology curriculum, organizing CDE programs, training courses and workshops to increase the knowledge awareness and guide the future dental students to
apply three-dimensional imaging technologies for better and accurate diagnosis.
KEYWORDS: Awareness, CT, CBCT, diagnosis, maxillofacial imaging, radiation dosage.
... Also, there is a lot of misconception regarding the dosage considerations for this imaging modality. [12] This study attempted to assess the knowledge of the Interns from two Dental Colleges regarding the understanding of the principles and applications of CBCT in Dental practice and their willingness to learn and constantly update their knowledge about CBCT. ...
... From the survey, we found that only 51.4% of respondents were aware of the working principle of CBCT. In a study by Lavanya et al. [12] among the post-graduate students in India, only 68.2% of the respondents were aware partially of the working principle of CBCT. However, they have not categorized the postgraduate students according to the year of study. ...
... Hence we feel that the awareness level of 51.4% among the interns seems agreeable. A significant difference noted for this question between our study and the study by Lavanya et al., [12] was the question in their study was subclassified as partial knowledge and complete knowledge. However, the criteria to define the same has not been validated. ...
Background: Cone-beam computed tomography (CBCT) is a new technology, in which two-dimensional detectors and conical beam are used instead of fan shaped beam in conventional computed CT. In CBCT, volumetric data are collected by the rotation of beam and detectors around the desired area of interest. The principal advantages of CBCT are in the smaller footprint of the machine and lower radiation dose. The knowledge of this imaging modality is limited and hence the application in clinical practice is not fully achieved. Aim: The present study aimed to assess the knowledge about Cone Beam Computed Tomography (CBCT) among interns of two Dental colleges in Chennai and their willingness to use this piece of imaging for their routine dental practice. Material and Methods: A closed-ended questionnaire was circulated to the interns of two dental colleges after obtaining necessary consent. Results: The results showed that there is a lack of knowledge regarding the application of this imaging modality and it is being applied in some areas where it is prone to give false-positive results. Conclusion: Overall, dentists had an average level of knowledge for CBCT. It is recommended that qualification programs to held for dentists to strengthen their awareness toward cone-beam computed tomography.
... This is attributed to the cost and unavailability of CBCT at the institution. This is in accordance with Reddy., et al. and Kumburoglu., et al. on Turkish dental students which highlighted difficulties with acquiring knowledge without practical experiences, thus the lack of CBCT unit at the institution may constitute a significant factor contributing to unfamiliarity with this technology [6,7]. ...
... and Reddy., et al. [6,7,10]. All the participants of the study were interested to attend hands on course on CBCT. ...
... Studies on pre-and/or post-doctoral dental education using CBCT imaging reported some gaps; one of them was image interpretation. 9,10 Thus, a web-based learning programme on CBCT interpretation might be an efficient and practical way to increase the knowledge and adjunct the educational process. Several studies have emphasised the advantages of web-based learning in dental education. ...
Cone-beam computed tomography (CBCT) examination of the tem-poromandibular joint (TMJ) has become a recognised tool in case of suspicion for the presence of osseous changes, after a thorough history and clinical examination of the patient. CBCT images provide high spatial resolution in three-dimensional (3D) images, which is desirable in diagnostics and treatment of temporomandibular disorder (TMD). Often, its diagnostic accuracy and reliability are better than that of two-dimensional (2D) images. 1 CBCT provides comparable diagnostic accuracy with a relatively lower radiation dose and cost compared with medical computed tomography (CT) 2-4 and, at present , is considered the technique of choice for evaluating osseous changes of the TMJ. 5 Abstract Objectives: To develop and evaluate an educational web-based programme for tem-poromandibular joint (TMJ) assessment using cone-beam computed tomography (CBCT). Methods: A web-based educational programme was designed for TMJ assessment using CBCT images. Fifteen CBCT cases of the TMJ (three-dimensional reconstructed volumes) and an assessment module based on image analysis criteria in the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) were added to the programme. Thirty-six undergraduate dental students were invited to test the programme by assessing all cases twice: before and after 2 months of training. Participants submitted written subjective evaluations of the programme. Results: The web-based programme can be accessed on Malmö University webpage (www.cbct-tmj.mau.se). Despite limited CBCT learning in their undergraduate training and not using the programme in the 2-month interval, the students were able to correctly diagnose 80% of the cases at the second assessment. Their diagnoses, however, did not differ significantly from the first assessment. Overall, the students were satisfied with the programme and considered it user-friendly. Conclusion: The web-based educational programme that was developed in the present study and tested by dental students could be a useful educational tool for TMJ assessment using CBCT.

... Konvensiyonel bilgisayarlı tomografi cihazlarına göre KIBT'in efektif dozu %98 daha azdır(12). Lavanya ve arkadaşları ile Ghonchech ve arkadaşlarının mezun diş hekimlerinin katılımıyla yaptıkları çalışmalarında, KIBT'nin efektif dozu ilgili katılımcıların bilgi seviyesi Lavanya ve arkadaşlarının çalışmasında yetersiz bulunurken; Ghonchech ve arkadaşları bu oranı daha yüksek bulmuştur.(13,14) Bu çalışmada ise, uzmanlık öğrencilerinin büyük çoğunluğu ile öğrencilerin yaklaşık yarısı KIBT ile ilgili doğru bilgiye sahipti ve uzmanlık öğrencilerinin KIBT ile ilgili bilgi düzeyi öğrencilere oranla daha yüksekti. ...
ÖZ
Amaç: Bu çalışmanın amacı diş hekimliği uzmanlık öğrencileri ve diş hekimliği öğrencilerinin radyasyondan korunma, radyasyonun etkileri ile ilgili farkındalığının ve bilgi düzeyinin değerlendirilmesidir.
Gereç ve Yöntem: Çalışmaya 108 son sınıf diş hekimliği öğrencisi ve farklı bölümlerde görev yapan 103 uzmanlık öğrencisi katıldı. Katılımcılara radyasyondan korunma, radyasyonun biyolojik etkileri ile ilgili bilgi düzeyini ölçmeyi amaçlayan, ‘Doğru/Yanlış ve Bilmiyorum’ seçenekleri bulunan 18 soruluk anket uygulandı. Çalışma sonucunda elde edilen sonuçlara göre iki grup arasında karşılaştırma yapıldı. Veri analizi SPSS programında, Ki kare testiyle yapıldı ve p değeri 0,05’ten küçük olan sonuçlar istatiksel olarak anlamlı kabul edildi.
Bulgular: Katılımcıların büyük çoğunluğu genel radyasyon bilgisi ve radyasyondan korunma ile ilgili soruları doğru yanıtladı. Bir adet periapikal radyograftan alınan radyasyon dozunun güvenilir ve sağlığa zararlı olmadığı ifadesini yanlış yanıtlayan uzmanların oranı (%45,6) öğrencilerden (%39,8) daha fazlaydı (p=0,255). Katılımcıların büyük çoğunluğu Hamile hastalardan kesinlikle radyograf alınmamalıdır ifadesine doğru yanıt verdi. (uzmanlar %89,3, öğrenciler, %91,3) (p>0,005). Radyasyonun stokastik ve deterministik etkisi hakkında her iki grubun yarısına yakını yeterli bilgiye sahip değildi (öğrenciler %48,5, uzmanlar %54,4) (p>0,005). Konik ışınlı bilgisayarlı tomografinin avantajları hakkında öğrenciler (%70,9) uzmanlara (%85,4) göre daha az bilgi sahibiydi.
Sonuç: Katılımcıların radyasyondan korunma ile ilgili bilgi düzeyi yeterliyken, radyasyonun etkileri hakkında bilgi düzeyi orta seviyedeydi. Bilgi düzeyinin ve farkındalığın artması için; diş hekimliği eğitimi boyunca radyasyonun biyolojik etkileri hakkındaki bilgiler daha fazla vurgulanabilir, mezun diş hekimlerine ise hatırlatma amaçlı eğitimler veya seminerler verilebilir.
Backgrounds
Canalis sinuosus (CS) is a neurovascular canal that corresponds to a small branch of the infraorbital canal.
Objective
This study aimed at assessing the knowledge and detection performance of CS among dentists and dental students.
Methods
Four-hundred and five dentists and dental students answered a questionnaire with three parts: 1. Socio-demographic; 2. Clinical cases with cone- beam computed tomography (CBCT) sections showing CS, and 3. Previous knowledge about CS. Chi-square test and Spearman’s correlation test were used to compare results as appropriate. P-values below 0.05 were considered statistically significant.
Results
Most participants did not identify CS in any CBCT. There was association between the number of correct answers and dental specialties. Most individuals had not learned about CS previously. There was association between past knowledge of CS and gender, highest academic degree, working environment, dental specialty, and number of correct answers but not with age or experience in dentistry.
Conclusions
This study suggests that most dentists are not aware about CS and do not know how to diagnose it. Previous knowledge about CS positively influenced its identification in CBCT.
Objectives: The use of cone-beam computed tomography (CBCT) in dental practice has increased in recent years for various reasons, ranging from the lower radiation dose and fast scanning time to the fact that it provides detailed images with fewer artifacts compared to conventional tomography. Although CBCT is frequently preferred in orthodontics, orthognathic surgery, head trauma, and implant surgery, especially for the evaluation of the craniofacial region, its use is still limited in paediatric dentistry. The objective of this study is to evaluate knowledge and attitudes regarding the use of cone beam computed tomography (CBCT) among paediatric dentists in Turkey.
Materials and Methods: A self-administered anonymous questionnaire consisting of 17 questions was completed by 273 voluntary participants. Of these participants, 135 were postgraduate students in a paediatric dentistry program and 137 were PhDs or specialists. Relationships between categorical variables were evaluated using chi-square test.
Results: 237 (86.8%) of 273 participants stated that they were knowledgeable about CT/CBCT. 81% of the responders expressed that the information they received during dental education was insufficient. When inter-variable dependency was assessed, the only significant relationship was between the participants’ self-rated knowledge about the use of CT and/or CBCT for the dentomaxillofacial region and the institutions in which they worked (P =.001).
Conclusions: Although our results indicate that paediatric dentists have high levels of knowledge and positive attitudes towards digital imaging techniques and CBCT, it would be beneficial to update the dental curricula and enable dental students to gain practical experience in addition to theoretical knowledge.
ÖZET
Amaç: Konik ışınlı bilgisayarlı tomografilerin (KIBT) diş hekimliğinde kullanımı son yıllarda oldukça yayılmaktadır. KIBT; ortodontide, ortognatik cerrahide, kafa travmalarında ve implant cerrahisinde, kraniyofasiyal bölgenin değerlendirilmesinde oldukça sık kullanılsa da, pedodontide kullanımı halen sınırlıdır. Bu çalışmanın amacı, Türkiye’de pedodontistler arasında KIBT kullanımına yönelik bilgi ve tutumun değerlendirilmesidir.
Gereç ve Yöntemler: Bu çalışma 273 gönüllü katılımcı ile gerçekleştirilmiş olup, katılımcılardan kendi kendine yönetilen ve 17 sorudan oluşan bir anketi isimsiz olarak doldurmaları istenmiştir. Katılımcıların 135’ini doktora/uzmanlık öğrencileri oluştururken, 137’si pedodonti doktoru ve/veya uzmanıdır. Bu araştırmada, kategorik değişkenler arası ilişkilerin incelenmesinde chi-kare testi kullanılmıştır.
Bulgular: 237 (86.8%) katılımcı BT/KIBT hakkında bilgi sahibi olduğunu belirtmiştir. Katılımcıların %81’i diş hekimliği eğitimi sırasında aldıkları bilginin yetersiz olduğunu bildirmiştir. Değişkenler arası bağımlılık değerlendirildiğinde, anlamlı tek fark, katılımcıların BT/KIBT kullanımı konusunda bilgi sahibi olup olmadıklarına dair soru ile çalıştıkları kurum arasında bulunmuştur (P =.001).
Sonuçlar: Çalışmamızın sonuçları, pedodontistlerin dijital görüntüleme yöntemleri ve KIBT kullanımına dair yüksek bilgiye sahip olduklarını ve olumlu tutum gösterdiklerini saptasa da, diş hekimliği müfredatının güncellenmesi ve öğrencilerin teorik bilginin yanı sıra pratik tecrübe edinmelerinin sağlanması, KIBT kullanımının yaygınlaşması ve yerinde kullanımının sağlanması açısından faydalı olacaktır.
Familiarity with cone beam computed tomography is a requisite for all dental practitioners involved in its use or referral. This scoping review examines the knowledge, attitudes, competence and confidence of dental practitioners and students towards cone beam computed tomography in the dental setting. A search of Medline, Scopus, Web of Science and Cumulative Index to Nursing and Allied Health Literature was conducted to identify and chart existing evidence. Relevant studies written in English and published after 1998 and up to July 2020 were included. Of 679 papers, 39 studies were included for analysis. Key findings include deficient knowledge despite a widespread recognition of its importance and willingness to increase proficiency in its use, as well as a largely positive and optimistic view of the technology. Future studies on practitioners' knowledge and attitudes towards cone beam computed tomography are suggested to consider the contexts of an Australian setting.
Background: Cone beam computed tomography (CT) has recently become effective for oral and maxillofacial imaging.
Objectives: The aim of this study was to assess the knowledge of dentists regarding cone beam computed tomography.
Materials and Methods: In this descriptive cross sectional study, a questionnaire regarding cone-beam computed tomography (CBCT) was distributed amongst 100 dentists (general and specialist) in Qazvin, Iran. Their level of knowledge was compared in each section on the basis of age, gender, years of employment and last educational status and analyzed by the SPSS software and Mann-Whitney test.
Results: Data analysis showed that 4% of dentists had very low, 16% had low, 50% had medium, 19% had good and 11% had in very good level of knowledge. The average of dentists’ knowledge was 57 ± 18. According to the statistical results, there was a significant difference between level of knowledge and age, years of employment and educational degree (P 0.05).
Conclusions: Overall, dentists had an average level of knowledge for CBCT. It is recommended for qualification programs to be held for dentists to strengthen their awareness toward cone beam computed tomography.

Abstract Aims and Objectives: The purpose of this study was to determine the knowledge and attitude of dentists towards CBCT in Mangalore, Karnataka, India and to assess the awareness of CBCT among dentists. Materials and Methods: A self-administered questionnaire of 23 multiple choice questions was given to 200 dentists working in reputed institutions in and around Mangalore .The questionnaire was given to the participants which took approximately 20 minutes for completion. Descriptive statistics was calculated in terms of frequencies and percentages. Results: All the participants of the survey were aware of CBCT and considered it to be a useful diagnostic tool in dentistry. The participants also believed CBCT had lower radiation dose compared to medical CT and data reconstruction could be performed easily in CBCT. The majority of the participants also reported that adequate teaching was not imparted regarding CBCT in educational institutions but were willing to attend courses and update knowledge on CBCT if provided with opportunities. Conclusion: CBCT has an important role in the diagnosis of oral and maxillofacial pathologies with reduction in radiation dose. The information obtained from the study highlighted the need for adapting to new technologies like CBCT and regular continuing education programmes, post graduate education courses, meetings and seminars are required to update dentists’ knowledge. The study also highlighted majority of participants believed CBCT are the ultimate diagnostic tool in dentistry and research
Cone-Beam Computed Tomography (CBCT) has been introduced in 1998. This radiological imaging procedure has been provided for dentistry and is comparable to computed tomography (CT) in medicine. It is expected that CBCT will have the same success in dental diagnostic imaging as computed tomography had in medicine. Just as CT is responsible for a significant rise in radiation dose to the population from medical X-ray diagnostics, CBCT studies will be accompanied by a significant increase of the dose to our patients by dentistry. Because of the growing concern for an uncritical and consequently rapidly increasing use of CBCT the Swiss Society of Dentomaxillofacial Radiology convened a first consensus conference in 2011 to formulate indications for CBCT, which can be used as guidelines. In this meeting, oral and maxillofacial surgery, orthodontics and temporomandibular joint disorders and diseases were treated and the most important and most experienced users of DVT in these areas were asked to participate. In general, a highly restrictive use of CBCT is re- quired. Justifying main criterion for CBCT applica- tion is that additional, therapy-relevant informa- tion is expected that should lead to a significant benefit in patient care. All users of CBCT should have completed a structured, high-level training, just like that offered by the Swiss Society of Den- tomaxillofacial Radiology.
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.
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.
