Background: Radiographs taken intra-orally are essential for planning a diagnosis; however the resulting two-dimensional images require thorough interpretation. Cone beam computed Tomographic (CBCT) imaging offers a more precise, three-dimensional image that could aid in proper diagnosis and treatment planning in endodontic and endo-perio cases.
Objectives: Assessment of CBCT referral reasons to private radiology centers, and its impact on modifying treatment plan in endodontic and endo-periodontal related cases.
Materials and Methods: This cross-sectional study comprised a total of 131 patients, who visited private radiology centers in Alexandria, seeking for CBCT scans, from July 2021to June 2022: All scans were inspected for assessing referral's reasons; referring dentists were asked about their reason for CBCT acquisition, and its effect on their diagnosis and treatment plan. Assessed cases were categorized into either a group of teeth with solitary endodontic-related problem or teeth with an endo-perio related problem.
Results: The number of teeth found with endo-perio radiographic problems in the CBCT scans was lower significantly than solitary endodontic cases (n=14, 8.4%,n=152, 91.5% respectively), Also, a significant difference was detected between those referred cases with endo-Perio lesions that were not previously root canal treated and those endodontic related cases that received earlier endodontic treatment (p=0.004*) , CBCT had a positive effect on changing endodontists' diagnosis and treatment plan, especially in endo-perio cases (p < 0.01٭).
Conclusion: CBCT is considered crucial for detection and proper diagnosis of endo-perio lesions. For all endodontic cases with missed canals, calcified canals and inflammatory resorptive defects, CBCT is deemed necessary.
