“…Reference [32] discovered that panoramic radiography underestimates the amount of resorption and proposed that CBCT images could benefit in both evaluation and therapy continuation or modification decisions. On the other hand, [33] claimed that while periapical and panoramic imaging can detect root resorption, they are not considered accurate due to the difficulties in discriminating between buccal and lingual surfaces and the amount of the resorption.…”

Introduction: Cone-beam computed tomography (CBCT) system is designed to provide 3- dimensional representation of the maxillofacial skeleton with high diagnostic quality of hard tissues of the maxillofacial skeleton. Aim: The aim of the present study was to evaluate the level of knowledge and attitude towards CBCT of orthodontists practicing in two Arab countries in the Middle East. Subject and Method: Data was collected through a questionnaire assessing the knowledge and attitude towards CBCT. Results: A total of 41 participants were enrolled in the study. The most common age group (63%) among participants was more than 40 years old. Knowledge score was calculated as the percent of the right answers from the total of 21 knowledge questions. the distribution of all respondent’s CBCT knowledge revealed that more than three-quarters of the respondents were moderately knowledgeable (76%) whereas 12.2% were in the low and high categories. Conclusion: The study results indicate that there is a definite gap in knowledge and attitude towards CBCT applications amongst the dental specialists. The dental specialists themselves reported lack of training in this field, and strongly urge a need for training in this field.

“…Although root resorption can be detected with periapical and panoramic imaging, they are not considered reliable due to the difficulty in differentiating between buccal and lingual surfaces and the extent of the resorption.

Introduction: Cone-beam computed tomography (CBCT) is currently being universally utilized for orthodontic diagnosis, treatment planning, and various research projects. However, there have been varied opinions regarding the appropriate use of CBCTs in the field of orthodontics. The knowledge and awareness about using CBCT in circumstantial diagnoses are not clearly understood and certain situations are still debatable, hence this study was performed to rank the knowledge among practitioners and graduate students across India. Materials and Methods: A nation-based, cross-sectional, and descriptive survey was conducted on 559 orthodontist and orthodontic postgraduate students and 18 questions were put forward to assess the knowledge and awareness. All of the 18 questions were then critically analyzed individually and descriptively concluded with appropriate references. Result and Conclusion: The survey showed that there were varying levels of awareness and it could be concluded that orthodontist needs to constantly update their knowledge and skills in interpreting and utilizing a CBCT. Furthermore, the need for bringing out a scientific and evidence-based national guideline for the appropriate use of CBCT is recommended.

“…7 Radiographic assessment of RR is primarily carried out with periapical radiographs due to their reduced exposure levels and operator convenience. 8 Recent systematic reviews have, however, emphasized on evaluating the three-dimensional nature of RR. 9,10 Lowdose CBCT scans taken in compliance with SEDENTEXCT guidelines are indicated in orthodontics for evidence-based research purposes and can potentially aid in monitoring patients at risk of resorption.…”

BackgroundRoot resorption in orthodontics is associated with direction and magnitude of force application as primary etiological factors. Well‐controlled trials that utilize three‐dimensional segmentation to detect volumetric changes in tooth structure are required to assess the quantitative nature of root resorption.ObjectiveTo assess the severity of root resorption (RR) during retraction of maxillary anteriors with three different force vectors (with and without skeletal anchorage) via cone‐beam computed tomography (CBCT) superimpositions.Trial DesignThree‐arm parallel randomized clinical trial (RCT).Materials and MethodsForty‐two (16 males, 26 females) patients, (17–28 years), in permanent dentition with bimaxillary protrusion were randomly allocated to three groups of 14 patients each using block randomization (1:1:1 ratio) and allocation concealment. En‐masse anterior retraction post first premolar extractions was carried out with modified force vectors in the three groups based on anchorage type [Molar, Mini‐implant and Infrazygomatic crest (IZC) bone screws]. Volumetric root loss and linear dimensional changes were blindly assessed on initial (T0) and final (T1, end of space closure) CBCT scans. Normality distribution of values was done using Shapiro–Wilk's test. ANOVA and Post‐hoc Tukey HSD test were done to compare measurements between groups at significance levels (P < .05).ResultsForty patients were analysed (14, 14, and 12 in three groups). Significant volumetric loss was noted in all groups. Central incisors demonstrated a significant reduction in IZC group (81.5 ± 21.1 mm3) compared to conventional (50.1 ± 26.5 mm3) and mini‐implant groups (76.1 ± 27.6 mm3). Canines demonstrated a significant reduction in mini‐implant group (108.9 ± 33.9 mm3) compared to conventional (68.8 ± 42.5 mm3) and IZC groups (103.1 ± 29.1 mm3). Regarding linear parameters, central incisors and canines revealed significant root length reduction in both skeletal anchorage groups. Lateral incisors showed no significant changes between groups.ConclusionsIntrusive force vectors generated during skeletally anchored retraction can predispose anteriors to an increased risk of resorption. Greater loss of root volume was noted in the centrals and canines when retracted with skeletal anchorage.LimitationsSmall sample size and variations during CBCT acquisition.HarmsLow‐dose CBCT scans were taken at T0 and T1 treatment intervals.
