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

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.

Comparative evaluation of push-out bond strength of AH-Plus, MTA-Fillapex and Epiphany SE root canal sealers: An Ex-Vivo study.

Background: A successful root canal (RC) treatment depends upon creation of a fluid impervious seal that is commonly built by using a RC sealer along with gutta-percha. The bond strength of the RC sealer is a hallmark as it will minimize the risk of treatment failure by reducing the possibility of filling detachment from dentin. Aim: To evaluate and compare the push-out bond strength of AH-Plus and MTA-Fillapex with Gutta-Percha and Epiphany Self Etch/Resilon system using the Universal Testing Machine. Materials and Method: About 60 mandibular premolars with single canals were prepared apically with Hyflex CM files upto size #30. Out of total, 20 teeth were obturated with AH-Plus/GP (group 1), 20 with MTA-Fillapex/GP (group 2), and other 20 with Epiphany Self Etch/Resilon system (group 3). Teeth were sectioned into three slices of 2 mm each and were subjected to Universal Testing Machine. Statistical Analysis: The data obtained were tabulated and statistically evaluated using SPSS version 21.0 statistical analysis software (IBM, Chicago, Illinois, USA). Results: The mean push-out bond strength was highest for AH-Plus (14.32 MPa) followed by MTA-Fillapex (12.18 MPa) and then Epiphany SE (8.44 MPa). The results were statistically significant. Conclusion: Significantly, higher push out bond strength was displayed by AH-Plus sealer than MTA-Fillapex and least being Epiphany SE sealer. The push out bond strength was significantly highest at apical third and lowest at coronal third.

Spectrophotometric analysis of color stability of esthetic restorative material in chlorhexidine mouthwash: An in vitro study.

Background: Commendable aesthetic properties of composites make it a pioneer filling material. However, discoloration of composite resin materials emerges as a major clinical problem in a long term. Aims and Objectives: Aim of the study is to evaluate the color stability of nano filled and micro hybrid dental composite resin in chlorhexidine mouthwash. Materials and Methods: 20 specimens of dimension 10*2mm were prepared of A2 shade. All the prepared samples were immersed in 20 ml of distilled water in separate containers according to the group. Further incubation at 37°C for 24 h was done. After 24 h, baseline color values of each sample were recorded using a spectrophotometer. After recording the baseline color measurements, 10 specimens (random selection) from each group were placed in 20 ml of 0.2% chlorhexidine mouthwash for 24 h duration. The L*a*b* system of the Commission Internationale de l'Eclairage (CIE L*a*b* Color Scale) was used for the determination of colorimetric values of the specimens. Results: The color change was displayed by both the samples after immersion in the mouthwash but the change was not statistically significant (0.763). ΔE value for nano filled composites is 3.25 while for the micro-hybrid composites the value is 3.56. Conclusion: The colorimetric values of nano filled composite resins are more stable than the micro hybrid composite due to exposure to chlorhexidine mouthwash.
