What is the classic sign of pit and fissure caries?
What is the classic sign of pit and fissure caries?
- Air abrasion and laser
- Gray or gray-yellow opaque area visible through the enamel
- Fiberoptic transillumination
- A sticky sensation felt on removal of the explorer (correct)
Why is tactile examination with a sharp explorer considered unreliable for detecting pit and fissure caries?
Why is tactile examination with a sharp explorer considered unreliable for detecting pit and fissure caries?
- It causes cavitation in demineralized pits and fissures
- Prevents the possibility of remineralization
- Produces false-positive and false-negative diagnosis (correct)
- Results in extensive radiographic detection

Study Notes
Pit and Fissure Caries
- The classic sign of pit and fissure caries is a "catch" or "stick" of a sharp explorer.
- Tactile examination with a sharp explorer is considered unreliable for detecting pit and fissure caries because it can cause damage to the tooth and may not detect early stages of caries.
- Laser fluorescence (LF) has been found to be a reliable non-destructive method for detecting pit and fissure caries.
- Dyes or disclosing agents may be helpful in visualizing pit and fissure lesions.
- The classic but unreliable sign of pit and fissure caries is a "catch" or "stick" of a sharp explorer, which is not a reliable indicator of caries.
- It is difficult to detect early pit and fissure caries lesions on a radiograph because the lesion may not be radiopaque enough to be visible or may be hidden by the surrounding anatomy.
