Caries detection systems

You suspect your patient has caries in the molar regions. Which of the following dental images should you take?

• Periapical

• Bite-wing

Buccal or lingual caries appear as a _____________________ on dental images.

• radiopaque triangle

• radiolucent small circle

According to the picture, which type of carious lesion is depicted?

• White Area: Later Stage (White Spot Lesion)
• Cavitated Lesion: coronal caries
• Cavitated Lesion: root caries
• White Area Lesion: Early Stage

The CAT in Pediatric dentistry is

• Caries Activity Test

• Caries Risk Assessment Tool

• Child Aptitude Test

ICDAS criteria are for :

• Tactile examination

• Visual examination

• Radiographic examination

• All of the above

Answer explanation

International caries detection and assessment system (ICDAS) use visual examination only .

ICDAS II (2005) is scoring system use :

• Two digit coding , 1st one for caries detection 2nd for the caries activity

• Two digit coding 1st one related to tooth restoration 2nd for caries progression level

• Three digit coding for restoration caries progression level and caries activity resectively

• One digit coding represent caries progression level

Answer explanation

correct answer is self explanatory .

DMFT/DMFS system is more comprehensive than ICDAS so it is better system to use in pediatric dentistry .

• TRUE

• FALSE

Answer explanation

ICDA system measuring the caries process in all stages thus gives better quality information in order to develop preventive strategies, to halt and reverse the disease, so the detection of non cavitated lesions become important mainly in young children .

While DMFT/DMFS system measures only cavitated caries and it can be used to estimate the needs of population to determine clinical care in children and adult .

Most common consentration of SDF used for caries managment is :

• 35%

• 36%

• 37%

• 38%

Pulpal inflamation and symptoms of spontanous pain contraindicate use of SDF

• TRUE

• FALSE

If SDF planned to be used , caries should be removed first :

• TRUE

• FALSE

Answer explanation

Studies have found that the removal of caries is not necessary before application of SDF and no need to tooth surface modifications .
