External root resorption (ERR) is a highly prevalent, multifactorial problem frequently associated with orthodontic treatment. Treatment is complex due to the lack of solid knowledge regarding predisposing factors, systematic management for diagnosis and follow-up protocols or thefundamental theoretical bases of adequate imaging tools for each situation. This review describes the indications of the use of cone beam computed tomography (CBCT) and the factors related to its development and the characteristics of the techniques used in the diagnosisand monitoring of ERR in orthodontics. We compared the advantages and disadvantages of CBCT based on the risk/benefits. Methods: We have reviewed and summarized the information and the risk factors available on ERR in orthodontics and the use of CBCT in the diagnosis and follow-up of ERR with the aim of developing a management protocol. Likewise, CBCT is compared with other imaging techniques frequently used in ERR. The articles reviewed in this study coincide in terms of the advantages of precision of CBCT in the detection and linear and volumetric measurement of ERR associated with orthodontics over two-dimensional techniques. However, CBCT cannot completely replace other imaging techniques since its effectiveness is not significantly greater in cases with moderate ERR compromise. The use of CBCT should be optimized following specific criteria for its application.

Objective: This study sought to assess the frequency and severity of second molar external root resorption (ERR) due to the adjacent third molar and its correlation with the position of third molar and other related factors using cone-beam computed tomography (CBCT). Materials and Methods: This cross-sectional study evaluated 320 second molars and their adjacent impacted third molars on CBCT scans of patients over 16 years, retrieved from the archives of Azad University Radiology Department. Presence/absence of second molar ERR, its location and severity (if present), and position of adjacent third molar were determined on CBCT scans, and recorded in a checklist. Data were analyzed using a logistic regression model. Results: The frequency of second molar ERR was 33.4% in the mandible and 14% in the maxilla. The severity of ERR was significantly correlated with the involved jaw (P=0.001) but had no correlation with age, gender, or depth of impaction of adjacent third molar (P>0.05). The mesioangular and horizontal positions of impacted third molars had a significant correlation with the frequency of second molar ERR (P<0.006). Conclusion: According to the results of this study, ERR occurring in second molars adjacent to third molars is common, especially in the mandible. Mesially inclined third molars have a greater potential of being associated with ERR in second molars.

Advantages And Disadvantages

This review provides an overview of the relevance of imaging techniques such as, computed tomography, cone beam computed tomography, and ultrasound, to endodontic practice. Many limitations of the conventional radiographic techniques have been overcome by the newer methods. Advantages and disadvantages of various imaging techniques in endodontic practice are also discussed.

ABSTRACT Internal resorption in the permanent dentition is a rare pathologic condition. Clinical differentiation of perforative cervical internal resorption from cervical external resorption is considered to be a challenging task. Advanced imaging techniques, such as cone beam computed tomography (CBCT) have proven vital diagnostic tools in the detection and management of these lesions. Management of a perforated internal resorption needs comprehensive endorestorative and periodontal approach. This article describes 1 year follow-up of the successfully managed perforative cervical internal resorption in permanent mandibular first molar. The affected tooth was endodontically treated, and the resorptive defect was restored with resin-modified glass ionomer cement (RMGIC) through periodontal flap surgery.

Clinic Practice

Cone-beam computed tomography (CBCT) has been widely used in diagnosis of vertical root fractures (VRFs) in recent years. According to the American Association of Endodontists (AAE) classification, there are five types of cracked teeth and VRF is one of them. Due to the variability and overlapping of the cracks and fractures, some narrow fractures on the roots of VRFs could not be detected by CBCT, and some wide cracks on the crown of cracked teeth could be detected by CBCT. In this review, we firstly discussed the value of CBCT in the diagnosis of the AAE five types of cracked teeth and presented CBCT manifestations of some typical cases. Secondly, we summarized the factors influencing the diagnosis of cracks/fractures using CBCT, namely, CBCT device-related factors, patient-related factors, and evaluator-related factors. The possible strategies to improve the diagnostic accuracy in the clinic practice are also discussed in this part. Finally, we compared the differences of root fractures with lateral canals and external root resorption on CBCT images.
