What is the primary purpose of caries diagnosis?

What are the basic tools for detecting caries lesions by visual inspection?
A. Bright light and a dental mirror
B. An x-ray
C. Fiber-optic transillumination
D. Electrical current
Which of the following is true about using a dental probe?
A. Vigorous poking cannot cause irreversible damage to the surface of a developing lesion.
B. Gentle probing does not disrupt the surface integrity of non-cavitated lesions.
C. The blunt side should never be used to remove biofilm.
D. Dental probes are no longer used in modern dentistry.
How does the ICDAS differ from the WHO Method of Caries Diagnostic Criteria?
A. ICDAS is focused on measuring fully cavitated lesions.
B. The WHO method is focused on measuring fully cavitated lesions.
C. There is no real difference between the two caries diagnostic methods.
D. The WHO method takes into account the entire continuum of the caries progression process.
Which of the two Caries Diagnostic Methods (WHO or ICDAS) is considered to be the most useful?
A. The WHO Method
B. The ICDAS Method
C. Both methods are considered equally useful.
D. Neither of these two methods is considered to be useful for caries diagnosis.
How many ICDAS codes are used to classify occlusal caries?
Considering the ICDAS system, which of the following conditions generally apply?
A. An active lesion is considered to have a greater likelihood of transition than an inactive lesion.
B. An inactive (arrested) lesion is considered to have a lesser likelihood of transition than an active lesion.
C. All lesions are considered to be likely to transition.
D. A and B
Which of the following factors influence the quality and interpretation of radiographic images when diagnosing caries lesions?
A. The shape, extent and location of the lesion.
B. The patient's insurance coverage specifications.
C. The number of potentially affected sites.
D. A and B
Which of the following is true about the usefulness of complementing the clinical visual–tactile examination with bitewing radiography?
A. Bitewing radiography does not help diagnose recurrent caries lesions.
B. Complementing the clinical examination with bitewing radiography increases the sensitivity of detecting occlusal and approximal caries lesions in children’s deciduous teeth.
C. Bitewing radiography lowers the sensitivity of diagnosis of dentin caries lesions.
D. Bitewing radiography can accurately diagnose enamel occlusal caries lesions in adult teeth.
Which of the following is a benefit of bitewing radiography?
A. It is only mildly invasive and painful.
B. It has limited surface accessibility.
C. It can completely replace the need for a visual-tactile examination.
D. Radiographs can be filed and reexamined at a later date to detect whether a lesion is progressing or not.
What is the main limitation of bitewing radiography?
A. The validity in diagnosing early lesions is rather low.
B. It does a bad job of detecting caries in children’s teeth.
C. It requires too much equipment.
D. Most dentists find radiographic images too hard to understand.
Which of the following methods of caries lesion detection and assessment is the only technique that is currently widely used in dental practice?
A. Quantitative laser-light induced fluorescence
B. The DIAGNOdent
C. Digital radiography
D. B and C
What is one reason behind having pediatricians help in caries diagnosis?
A. Children do not like dentists, but they like pediatricians.
B. Pediatricians have more tricks for making children keep their mouths open to be examined.
C. One study found that pediatricians who did two hours of training were able to identify a cavitated lesion with an accuracy level similar to that of dentists.
D. Most dentists do not include children in their practice.
