- Quantitative Light-Induced Fluorescence (QLF)

What tool can you use to visually detect and assess caries?

BIte-wings

What type of radiograph is useful to detect and assess caries?

Quantitative Light-Induced Fluorescence (QLF)

What type of tool to detect caries?

Measures the amount of fluorescence emitted by tooth structure when exposed to a specific wavelength of light (often blue or violet light). Healthy enamel emits a measurable amount of fluorescence, while carious lesions emit less. The system quantifies this difference and displays it as a grayscale image, with darker areas indicating higher fluorescence (often sound enamel) and lighter areas indicating lower fluorescence (often carious tissue)

NIRI technology (Near Infra-Red Imaging)

(NIRI technology shines near-infrared light through the teeth. Healthy enamel is transparent to this light, appearing darker on the scan, while dentin and decayed areas scatter the light, making them appear brighter. This contrast helps dentists identify areas of concern effectively)

What type of tool to detect caries?

An advanced diagnostic tool used primarily in dentistry to detect cavities and monitor dental health without exposing patients to harmful radiation

What is the classification?

True

T/F: Untreated dental caries (tooth decay) in permanent teeth is the most common health condition according to the Global Burden of Disease 2021.

False (Cavity is the visible manifestation)

The disease is multifactorial:

- Biofilm dysbiosis (it becomes cariogenic)

- Frequent sugar exposure

- Susceptible tooth surfaces (deep grooves, cavitations, chips)

- Inadequate fluoride exposure

- Host susceptibility that can lead to an imbalance in the cycle of demineralization and remineralization causing localized destruction of tooth structure

T/F: The cavity is the disease

The balance between pathological (risk) factors and protective factors
