Summary
Conventional film imaging showed more root canal length than three phosphor plate systems (Digora, Digident, Denoptix). This difference in imaging may be clinically significant for dental diagnostics.
Area of Science:
- Dental Imaging
- Radiology
- Endodontics
Background:
- Intraoral imaging is crucial for diagnosing root canal anatomy.
- Phosphor plate systems offer digital advantages, but their diagnostic efficacy requires comparison with conventional radiography.
Purpose of the Study:
- To compare the diagnostic accuracy of three phosphor plate intraoral imaging systems (Digora, Digident, Denoptix) against E-speed conventional film for visualizing root canals.
Main Methods:
- Sixty extracted teeth were imaged using conventional film and three phosphor plate systems.
- Root canal visibility was measured as a percentage of the total canal length from the cementoenamel junction to the apex.
- Images were evaluated by two examiners under standardized conditions, with digital images enhanced for clarity.
Main Results:
- Conventional film displayed a mean of 90% of the root canal length.
- Phosphor plate systems showed lower percentages: Digora (78%), Digident (81%), and Denoptix (83%).
- Significant differences were found between conventional film and Digora/Digident, but not with Denoptix or among the phosphor plate systems.
Conclusions:
- Conventional film provided superior visualization of root canal length compared to the tested phosphor plate systems.
- The observed differences in root canal visibility may have clinical implications for endodontic diagnosis and treatment planning.
