“…Another systematic review and meta-analysis [ 1 ] refer to a different idea, suggesting that CBCT has a higher diagnostic efficacy than PR. A recent study [ 40 ] of the diagnostic accuracy of CBCT and 2D imaging methods in the 3D localization and assessment of maxillary impacted canines suggests that the diagnostic accuracy of CBCT outperformed 2D radiography in localizing the position of the impacted canines and the resorption of the adjacent incisors. However, a comparison with the present study is difficult because they are treating a special situation of impacted canines.…”

Objectives: This clinical study aimed to evaluate and compare the diagnostic accuracy of intraoral periapical radiography (PR) and cone beam computed tomography (CBCT) in detecting external apical root resorption (EARR) in orthodontic patients during the retention phase. Methods: The research involved 41 Caucasian patients who had undergone comprehensive orthodontic treatment, with a total of 328 teeth analyzed. The Kappa values for inter- and intra-examiner agreement were high for both PR and CBCT, indicating a robust level of agreement among examiners. The study used a four-point scale for classifying EARR. Results: This study showed comparable accuracy, sensitivity, and specificity between PR and CBCT when using the most stringent criterion of “Definitely present”. The data suggested that CBCT outperformed PR when using a less stringent criterion (“Definitely present” or “Probably present”), particularly for maxillary incisors. However, overall diagnostic performance, as measured by the area under the ROC curve, showed only a slight advantage for CBCT over PR. Areas under the ROC curve range between 0.85 and 0.90 for PR and between 0.89 and 0.92 for CBCT. According to DeLong’s test, there is no evidence to conclude that the area under the ROC curve is different for PR and CBCT. Conclusions: Both PR and CBCT are accurate diagnostic tools for identifying EARR, with PR being deemed more suitable for routine clinical use due to its cost-effectiveness and lower radiation exposure. The findings emphasize the importance of considering the risk-benefit ratio when deciding on imaging modalities for monitoring EARR in orthodontic patients.

“…With the knowledge of the impacted canine eruption path length, impaction depth, and impaction height, it is possible to predict the forced eruption time of the impacted canine [ 19 ]. Several studies emphasize the superior diagnostic accuracy of CBCT over conventional radiography [ 20 – 23 ]. Bodner et al, after analyzing the accuracy of impacted teeth images by comparing conventional radiography and computed tomography, stated that the crown and root shape, crown-root ratio, and inclination of the tooth were observed more clearly in computed tomography images than in 2D radiographs [ 22 ].…”

Similarly, Alfailany et al reported that CBCT demonstrated superior performance compared with 2D radiography in accurately determining the position of the impacted maxillary canines (labio-palatal, mesio-distal, and vertical), assessing the development of the root apex, detecting the presence of resorption in the adjacent incisors, and diagnosing the ankylosis of impacted canines [ 23 ].…”

Background This study aimed to evaluate the crown length and width and root length and dilacerations in unilateral impacted maxillary canines, compared with contralateral erupted canines, and to investigate the relationship between the morphology of impacted canines and their localization. Material/Methods Pretreatment cone beam computed tomography (CBCT) of 40 patients (age range 11–34 years) with unilateral impacted maxillary canines (IC) were analyzed. The crown length, crown width, root length, and dilacerations of IC were assessed and compared with that of contralateral erupted canines (CC). The eruption path length, impaction depth, and impaction height were measured, and mesio-distal and labio-palatal positions of the IC were determined. Results Crown length and width of IC were significantly greater, by 0.15 mm and 0.26 mm, respectively, than that of CC (P <0.001). Root length of IC was shorter than that of CC by 1.46 mm ( P <0.001). Root dilaceration was found in 72.5% of IC and 60% of CC ( P =0.213). The mean dilaceration angle of IC was 8.84° higher than that of CC ( P >0.05). Correlations existed between direction of dilaceration and length of the eruption path ( P =0.027), IC root length and depth of impaction ( P =0.017), root length ( P =0.037), and direction of root dilaceration ( P =0.03) and the position of the IC in the mesio-distal direction. Conclusions IC crown length and width were significantly longer than that of CC, while IC root length was shorter. Longer root length was observed in impacted canines with greater mesio-distal and horizontal dislocation.

Introduction: En-masse maxillary anterior retraction is necessary to attain an esthetic profile in Angle's class I bimaxillary dentoalveolar protrusion and Angle's class II division 1 malocclusion. The objective of this study was to evaluate configurational relationships between maxillary incisors and incisive canal in Angle's class I bialveolar protrusion and Angle's class II division 1 malocclusion by cone-beam computed tomography (CBCT). Methods: A total of 108 adult CBCT scans of 54-skeletal class I bialveolar protrusion and 54-skeletal class II division 1 malocclusions were retrospectively analyzed. Angles between palatal plane and axis of maxillary alveolar border (θ1), incisive canal (θ2), and maxillary right central incisor (θ3) were measured in relation to the midsagittal plane. Linear measurements such as incisive canal width (IC-IC), medial inter-root distance (Rm-Rm), posterior inter-root distance (Rp-Rp), anteroposterior distance from Rm to tangent of right central incisor (11 Rm-Cat), and left central incisor (21 Rm-Cat) corresponding to three vertical levels (L1, L2, and L3) were assessed in axial cross-sectional plane. Association among angular measurements was examined by Spearman correlation coefficient analysis. Mann-Whitney U test compared variables of linear measurements at three vertical levels. Results: Estimated distance from incisor root to incisive canal was 5-6 mm in both groups slightly influenced by skeletal class and vertical levels but not gender. Mann-Whitney test demonstrated significant differences between groups at three vertical levels (p<0.05). Only θ2 revealed a significant difference (p<0.05) between malocclusions compared to θ1 and θ3. The angular measurements for both malocclusions were positively correlated (p<0.05). Conclusion: Sagittal root-canal cortical plate distance varied significantly in both malocclusions (5-6 mm). Inter-root distance (Rp-Rp) was greater than incisive canal width (IC-IC) at all three vertical levels indicating a reduced possibility of canal invasion after maximum retraction at posterior levels.
