Summary
Comparing diagnostic systems for occlusal caries, this meta-analysis found electrical resistance and fiber-optic transillumination performed best. Visual inspection and xeroradiography showed poor performance in detecting these dental caries.
Area of Science:
- Dentistry
- Diagnostic Imaging
- Biomedical Engineering
Background:
- Comparing diagnostic systems for occlusal caries is challenging due to limitations of sensitivity and specificity.
- A need exists for a unified metric to evaluate and compare diagnostic test performance.
Purpose of the Study:
- To conduct a meta-analysis comparing the performance of various diagnostic systems for occlusal caries.
- To overcome the limitations of traditional parameters like sensitivity and specificity for comparative analysis.
Main Methods:
- A meta-analysis of nine in vitro and one in vivo study was performed.
- Sensitivity and specificity values were converted to normal deviate values.
- DZ values were calculated to quantify diagnostic test performance above chance.
Main Results:
- Electrical resistance measurements and fiber-optic transillumination demonstrated superior performance in occlusal caries detection.
- Visual inspection and xeroradiography exhibited poor diagnostic performance.
- Other radiographic modalities showed intermediate performance levels.
Conclusions:
- Electrical resistance and fiber-optic transillumination are promising diagnostic tools for occlusal caries.
- Visual inspection and xeroradiography are less effective for diagnosing occlusal caries.
- The DZ value offers a valuable metric for comparing diagnostic test efficacy.
