“…Additionally, the kV is responsible for the voltage at which the electrons are subjected and, consequently, for the energy of the resulting X-ray photons, which affects the balance between photoelectric and Compton effects when interacting with the matter 3 , 11 , 30 . As previously mentioned, unlike mAs, kV does not have a linear relationship with effective dose 29 . Therefore, kV selection should be carefully optimised to the specific indication for a specific CBCT unit, given that a lower-energy spectrum may be absorbed or scattered within the tissues resulting in higher effective dose.…”

“…When comparing the exposure settings of the two dose protocols used in the present study, the optimised protocol made use of reduced mAs (from 100 to 24) and kVp (from 90 to 70), which resulted in an eightfold reduction of the dose-area-product (from 7.13 to 0.86 mGycm 2 ). Because the mAs is more efficient for dose reduction and the kV alone may not have a direct and linear influence on the effective dose 29 , it is important to highlight that the optimised protocol of the present study was based on the study by Oenning et al 26 , which also made use of human phantoms and the same CBCT unit to evaluate six scanning protocols adjusted at varying exposure settings for the visualisation of specific anatomical features; they found that reduced levels of mA, kV, and exposure time resulted in reduced effective dose, calculated by means of a customized Monte Carlo framework. Also, in the present study a smaller FOV size (5 × 5 cm) was used as such to increase the exomass as compared to the previous study (8 × 8 cm) 26 .…”

Dose optimisation has been revisited in the literature due to the frequent use of cone beam computed tomography (CBCT). Although the reduction of the field-of-view (FOV) size has shown to be an effective strategy, this indirectly increases the negative effect from the exomass. The aim of this study was to evaluate the diagnostic accuracy of an optimised CBCT protocol in the detection of simulated vertical root fracture (VRF) in the presence of metal in the exomass and/or inside the FOV. Twenty teeth were endodontically instrumented and VRF was induced in half of them. All teeth were individually placed in a human mandible covered with a soft tissue equivalent material, metallic materials were placed at different dispositions in the exomass and/or endomass, and CBCT scans were obtained at two dose protocols: standard and optimised. Five radiologists evaluated the images and indicated the presence of VRF using a 5-point scale. Area under the ROC curve (AUC), sensitivity, and specificity were calculated and compared using ANOVA (α = 0.05). Overall, AUC, sensitivity, and specificity did not differ significantly (p > 0.05) between the dose protocols. In conclusion, optimised dose protocols should be considered in the detection of simulated VRF irrespective of the occurrence of artefacts from metallic materials in the exomass and/or inside the FOV.

“…[ 2 ] Good radiological practices help in reducing unnecessary radiation exposure in children. [ 3 5 ] The pediatric population is more susceptible to the risks of ionizing radiation. This is because of the higher mitotic activity which leads to the higher radiation sensitivity of tissues as the tissues are less developed and contain more undifferentiated cells in children.…”

Aim: To evaluate the prevalence of prescribing panoramic radiographs in children less than 6 years of age. Materials and Methods: The retrospective study was conducted in a dental institution in Chennai between December 2019 and January 2021. Details of all the children less than 6 years subjected to panoramic radiographs were collected. The reason for taking panoramic radiographs was also recorded. Chi-square tests were done to statistically analyze the data, and the significance level was set at 0.05 Results: Out of 2,847 children less than 6 years of age visiting the dental institution, 1.08% (31 children) were advised to take an orthopantomagram (OPG) during the study period. Early childhood caries (75% in males and 66.7% in females) was found to be the most common reason for taking panoramic radiographs followed by developmental disturbances (12.5% in males and 13.3% in females). Chi-square test showed statistical significance between males and females ( P - value = 0.003 and 0.002) for the reasons for taking panoramic radiographs in children Conclusion: Usage of radiographic techniques, especially panoramic radiographs should be limited for children under 6 years of age unless absolutely necessary.

“…Nowadays, two-dimensional techniques like occlusal, bite-wing (BW), periapical, panoramic, and cephalometric radiographs are primary and conventional diagnostic imaging techniques employed in pediatric dentistry. However, the multislice computed tomography, radioisotope imaging (nuclear medicine), contrast studies, as well as ultrasound and magnetic resonance imaging (MRI) have made small contributions to the daily dental practice (7). Among the given techniques, imaging, ultrasound, and MRI do not emit ionizing radiation and, hence, have no negative impacts on human health and can address safety concerns over radiation protection.…”

Background: Radiological examinations expose the patient to the adverse effects of ionizing radiation, which is more severe among developing children. This can cause excessive and unreasonable fear and anxiety for parents and even disrupt the treatment process. This study aimed to evaluate the parents’ knowledge about dental radiographs for children referred to dentistry, and to assess the relevant factors. Methods: The present study is a cross-sectional analytical study examining parents of children referred to dental clinics from October 2019 to April 2020. The required information included demographic information, and nine statements for assessing parents’ level of knowledge. One-way analysis of variance (ANOVA), independent t-test, and linear regression were used to analyze the data. Ward’s cluster analysis method with a squared Euclidean distance was adopted to include the background and demographic variables. Results: A total of 108 parents of children referred to Ilam dental clinics – including 69 females (68.3%) and 32 males (31.7%) in the 24-51 age range, participated in this study. Among the studied variables, the level of educational attainment of the parents had a highly significant influence (P<0.01) on their knowledge of pediatric radiography. Furthermore, parents holding bachelor’s degrees or higher with an average score of 5.35 had more heightened awareness of radiography than those in other educational groups. Conclusions: Examining the parental radiographic knowledge revealed significant differences among three groups of parents with educational attainment in favor of those with higher educational achievement. In general, three biographical variables, namely age, gender, and household size were found to be less influential. Therefore, the dentists should learn about the educational attainment of the parents and provide them with the required information on treatment accordingly. Due to the relatively poor knowledge of the parents about children’s dental radiographs, it is recommended that plans be developed for raising the parental awareness of the issue in order for reducing their unreasonable fears which may create a burden for dental treatment procedures.
