New Methods of Detection of Caries

Question 1

Tools used to assessed the operator

Answer 1

1. Magnification
2. Loupes.
3. Microscopes.

Question 2

DIAGNO dent: laser based device is

Answer 2

device work on the fluorescing nature of bacterial by product .

Red light with wave length 655nm is transported to a tip of device.

Question 3

DIAGNOdent advantage

Answer 3

The quantitive for Patient complies nature the extent with every reading .

Patient complies with this scenario as he can see the evidence every time he’s examined

Question 4

DIAGNO dent –Infra-red laser florescence.(dis- advantage)

Answer 4

Doesn’t detect the caries detect the bacterial porphyrin by product

Question 5

DIAGNO -dent – Infra red laser florescence, (advantage)

Answer 5

1. Pleasant method to patient (pain free) , quick and easy
2. Reduced use of the manual probe , decreased abrasion of the enamel
3. Billable follow up service (mobile)

Question 6

DIFOTI works based on fact that

Answer 6

The caries enamel has a lower index of light transmission than sound enamel
It detects incipient caries as well as fractures

Question 7

Fibre - optic trans illumination is effective ….

Answer 7

As a detailed visual inspection in detecting occlusal caries + has a low sensitivity in detecting inter proximal caries

Question 8

QLF system uses …

Answer 8

A blue light (488nm wavelength)

Question 9

Answer 9

Tooth demineralisation and lesion severity

Question 10

Answer 10

Bitewing projection to minimise overlap of the teeth
+ occlusal caries confined to enamel is not identified on radiographs
