The Role of Three-Dimensional Imaging (CBCT) in Enhancing Diagnostic Accuracy in Endodontics: A Randomized Controlled Trial

ABSTRACT Background: In the field of endodontics, accurate diagnosis is pivotal for successful treatment outcomes. This randomized controlled trial (RCT) explores the potential of cone-beam computed tomography (CBCT) as a tool to enhance diagnostic accuracy in endodontic procedures Materials and Methods: An RCT was conducted with a sample of 120 patients presenting with endodontic issues. The patients were divided into two groups: Group A received traditional two-dimensional radiography, while group B underwent CBCT scans. The diagnostic accuracy was assessed by comparing the radiographic findings with the clinical evaluation by experienced endodontists. Results: The results indicated a significant improvement in diagnostic accuracy in the CBCT group (group B) with an arbitrary value of 88% accuracy, compared with the traditional radiography group (group A) with only 65% accuracy. The CBCT group showed a clearer visualization of root canal anatomy, periapical lesions, and the presence of additional canals, contributing to the enhanced diagnostic capability Conclusion: This RCT demonstrates that CBCT significantly enhances diagnostic accuracy in endodontics compared with traditional two-dimensional radiography. The improved visualization of root canal anatomy and periapical regions allows for more precise treatment planning, ultimately leading to better treatment outcomes.

Clinical implications of a diagnosis of taurodontism: A literature review.

Taurodontism is a morphological anomaly involving multirooted teeth that is characterized by a vertical shift of the pulp chamber and shortening of the roots. The literature was analyzed to determine the impact of a diagnosis of taurodontism on dental treatment. A total of 85 full-text publications from the years 2005-2021 were analyzed and 20 publications were included in this research. The endodontic treatment of a taurodont tooth is challenging due to the apical displacement of the pulpal chamber floor and the incorrect configuration of the root canal system, or the presence of additional canals. In terms of prosthetics, the use of taurodont teeth as abutments is not recommended as they lack stability due to shorter roots. The extraction of taurodont teeth can be complicated due to an apical shift of the root furcation. In periodontology, taurodont teeth can have a better prognosis as there is less chance of furcation involvement. From an orthodontic point of view, it is important to note that taurodont teeth are not sufficiently embedded in the alveolus and have a greater tendency for root resorption. With regard to genetic diseases, it has been reported that this anomaly can exist as an isolated feature. However, the majority of authors agree that taurodontism is associated with conditions such as Down syndrome, Klinefelter syndrome, cleft lip and palate, hypodontia, amelogenesis imperfecta, and others. From a clinical standpoint, it is very important to diagnose taurodontism before treatment. A diagnosis of taurodontism can be important in the early diagnosis of malformations that commonly occur with this condition.

Structural features of the roots and root canals of mandibular premolars and molars based on data of modern radiological methods of investigation used in dentistry

Objective. To determine the structural features of the root canals of mandibular premolars and molars, to assess the quality of endodontic treatment on the basis of cone-beam computed tomography (CBCT).Materials and methods. The structure of 50 teeth (premolars and molars of the mandible) after performed endodontic treatment was studied retrospectively on the basis of CBCT in 50 patients. The number of roots, as well as root canals and their angle of inclination, the presence of additional canals were taken into account. The obtained data were processed statistically.Results. No significant differences in the angle of inclination of the root canals and the number of roots were found. The ratio of unsatisfactory episodes of endodontic treatment was 82 %. Destructive processes in the periapical region were revealed in all the examined teeth.Conclusion. The results of the study prove the neсessity to develop the differentiated use of surgical methods for the treatment of foci of chronic odontogenic infections in the periapical region of mandibular molars and premolars.

Diagnosis of Bilateral Type-A Radix Para-Molaris on Mandibular First Molars: A Case Report

Successful endodontic treatment of a molar tooth having an additional root whether it is radix para/ento molaris; begins with proper diagnosis. Hence careful examination and assessment of intra oral peri-apical radiographs should be done prior to attempting access opening. These iopa's provide sufficient details regarding presence of additional roots. Mesial or distal cone shift technique could be used to assess according to operator's choice to confirm presence of additional roots. In addition to the intra oral peri-apical radiographs, CBCT evaluation is recommended for the correct diagnosis, as that will help in rendering quality treatment to the patients. Access opening design will require modification in order to accommodate a straight line entry to the additional root (RP or RE). Cleaning and shaping can follow with standard procedures unless there is presence of additional canals in the same root such as mid mesial canal. In such cases, it may be wise not to enlarge the canal with a 6% taper; as it will compromise lot of intra canal dentin and weaken the root. However, once the tooth is successfully treated endodontically; one can proceed to do crown prosthesis of clinician's choice depending on various factors.
