Knowledge and Attitude of Iranian Dentists Towards Cone-Beam Computed Tomography

Abstract

Objectives: We aimed to evaluate the knowledge and attitude of Iranian dentists towards cone-beam computed tomography (CBCT). Materials and Methods: A 20-item questionnaire was distributed among 410 Iranian dentistry graduates attending the 56th Congress of Iranian Dental Association held in Tehran, Iran. The questionnaire included items on demographic characteristics, namely full name, age, gender, work experience, type of current activity (individual or group), and the highest educational level. In addition, the questionnaire contained items on the knowledge and attitude of dentists. The obtained data were analyzed using statistical tests. Results: In this study, 49.3% and 22.4% of the subjects were male and female, respectively, 47.1% of whom used CBCT, while 49.8% did not. In detail, 72.2% of the dentists used the technique to evaluate the location of implants, whereas 19.7%, 3.2%, and 2.7% of the subjects applied it to localize the inferior alveolar nerve (IAN), evaluate the location of implants and localize the IAN, and perform cephalometric analysis, respectively. The main causes of lack of prescription of CBCT entailed high cost (80%), high rate of patient absorbed dose (27.6%), insufficient number of CBCT centers (46.3%), and the long duration of the process (15.6%). Conclusion: CBCT is an advantageous imaging technique in dentistry. Considering the increased application of CBCT in dentistry, attending workshops could help train dentists to use the technique.

Knowledge Level of Iranian Dental Practitioners Towards Digital Radiography And Cone-Beam Computed Tomography

“…In our study, the indications of CBCT that were most commonly agreed upon were preoperative evaluation for implant placement, assessment of the position of third molars, and 3D evaluations while the participants had the lowest level of knowledge about the indications of CBCT for orthodontic treatment planning, morphological assessment of root canals and evaluation of root resorption. Ghoncheh et al [13] reported that 72.2% of the dentists used the CBCT technique to evaluate the location of implants, whereas 19.7%, 3.2%, and 2.7% of the subjects applied it to localize the inferior alveolar nerve (IAN), evaluate the location of implants and localize the IAN, and perform cephalometric analysis, respectively. Mahdizadeh et al reported that the main indications of CBCT included implant placement, assessment of cysts and tumors, and trauma cases while CBCT was least commonly prescribed for periodontal disease and caries.…”

Diş Hekimliği Öğrencileri ve Uzmanlık Öğrencilerinin Radyasyondan Korunma ve Radyasyonun Biyolojik Etkileri Hakkındaki Farkındalığının Değerlendirilmesi

“…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. Uzmanlık öğrencilerinin, dişte uzmanlık sınavında başarılı olabilmek için lisans eğitim bilgilerini tazelemeleri ve mesleki deneyimlerinin öğrencilere göre daha fazla olması uzmanlık öğrencilerinin bu soruda bilgi düzeyinin daha yüksek bulunmasına neden olmuş olabilir.…”

Cone beam computed tomography in dentistry: practitioner awareness and attitudes. A scoping review

“…The introduction of cone beam computed tomography (CBCT) in the dental practice has significantly contributed to diagnosis and treatment planning. First presented in the European market in 1996, CBCT is a three‐dimensional dentomaxillofacial imaging modality which has an important role in the dental setting 1 . In recent years, with continuous technological advances in these devices, together with a reduction of cost, there has been a general increase in CBCT availability 2 …”

“…CBCT holds several advantages over computerized tomography (CT), panoramic and intraoral imaging which has resulted in its widespread application in dentistry 1,2 . Namely, CBCT has been applied in the fields of implantology, endodontics, orthodontics and pathology assessment, due to the ability to visualize structures in horizontal, vertical and axial views 2,3 .…”

“…Namely, CBCT has been applied in the fields of implantology, endodontics, orthodontics and pathology assessment, due to the ability to visualize structures in horizontal, vertical and axial views 2,3 . Notably, CBCT confers a reduced cost, reduced space consumption, limited field of view, rapid scanning time and, most notably, a reduced average radiation dosage in comparison to CT 1,2 . Nonetheless, the limitations of CBCT should be considered, including poor contrast and high radiation dosages, compared to those of conventional radiographic techniques such as intraoral and panoramic radiography 3 .…”
