Area of Science:

Dental diagnostics
Caries detection technologies

Background:

The field of caries diagnostics has seen advancements in non-invasive detection and monitoring tools over the past 15 years.
Several novel aids are now available to dentists, with ongoing research promising further developments.

Purpose of the Study:

To review currently available non-invasive caries diagnostic aids for dental practitioners.
To discuss the principles, applications, and limitations of emerging caries detection technologies.

Main Methods:

Laser fluorescence (LF): utilizes back-scattered fluorescence from a 655-nm light source for lesion detection and monitoring.
Quantitative light-induced fluorescence (QLF): detects and quantifies mineral loss in enamel and dentine lesions.
Subtraction radiography: digitally superimposes radiographs for detecting approximal and occlusal caries.

Electrical caries measurements (ECM): gathers site-specific or surface-specific tooth structure information.

Main Results:

LF enhances occlusal and approximal lesion detection but can yield false positives.
QLF is sensitive for mineral loss but may have lower specificity than visual detection.
Subtraction radiography is applicable for specific caries types but not widely available.
ECM shows promise for occlusal dentine caries and potentially other surfaces with multi-frequency approaches.

Conclusions:

Current non-invasive caries diagnostic methods require further research and clinical validation.
These technologies have potential future applications in personalized caries management systems.
Integrating these tools could enhance comprehensive dental care strategies.
