Summary
This study found no statistical difference in detecting proximal caries between intraoral film and charge-coupled device (CCD) imaging. Both digital radiography and traditional film accurately identified cavities in posterior teeth.
Area of Science:
- Dental Radiology
- Diagnostic Imaging
- Caries Detection
Background:
- Accurate detection of proximal caries is crucial for timely dental treatment.
- Traditional intraoral radiography has limitations in visualizing early interproximal lesions.
- Digital imaging technologies offer potential improvements in diagnostic accuracy.
Purpose of the Study:
- To compare the diagnostic accuracy of charge-coupled device (CCD) receptors versus intraoral film for detecting proximal caries.
- To evaluate the effectiveness of digital radiography in identifying interproximal dental caries.
Main Methods:
- Four observers assessed 40 extracted posterior teeth for proximal caries.
- Images were captured using both intraoral film and a CCD receptor.
- Ground section histology served as the gold standard for verification.
- Receiver operating characteristic (ROC) analysis was employed to evaluate performance.
Main Results:
- No statistically significant difference was found in the areas under the ROC curves (Az) between the CCD receptor and intraoral film.
- Both imaging modalities demonstrated comparable accuracy in detecting proximal caries.
- Observer performance was analyzed using paired t-tests.
Conclusions:
- CCD-based intraoral sensors provide diagnostic accuracy for proximal caries detection comparable to conventional intraoral film.
- Digital radiography is a viable alternative to film-based radiography for interproximal caries diagnosis.
- Further research may explore advanced digital techniques for enhanced caries detection.
