ICDAS Code 1 |
White spot seen through saliva (while wet)
Apply fluoride varnish to 1. Arrest and remineralise ACTIVE lesions 2. Maintain ARRESTED lesions |
|
|
ICDAS Code 2 |
White spot seen AFTER 5 seconds of drying Apply fluoride varnish to 1. Arrest and remineralise ACTIVE lesions 2. Maintain ARRESTED lesions |
|
|
ICDAS Code 3 |
White or brown spot, the WHO probe drops down to disclose enamel breakdown (0.5mm) Treatment:
Restore with ultra conservative sealed restoration (UCSR) only if associated radiolucency extends deeper than C4. Otherwise apply resin based sealant and review in 6 months with BW |
|
|
ICDAS Code 4 |
Shadow from dentine (with or WITHOUT enamel breakdown) Treatment:
Restore with ultra conservative sealed restoration (UCSR) only if associated radiolucency extends deeper than C4. Otherwise apply resin based sealant and review in 6 months with BW |
|
|
ICDAS Code 5 |
Cavity into dentine confirmed on probing (more than 0.5mm of WHO probe drops into cavity) Treatment:
Restore with ultra-conservative sealed restoration (UCSR) |
|
|
ICDAS Code 6 |
Frank cavitation Treatment:
Restore |
|
|
Radio Code 1 |
Outer 1/2 of enamel Treatment:
Apply topical fluoride and monitor |
|
|
Radio Code 2 |
Inner 1/2 Enamel Treatment: Apply topical fluoride and monitor |
|
|
Radio Code 3 |
Just into dentine Treatment: Apply topical fluoride and monitor |
|
|
Radio Code 4 |
Outer 1/3 of dentine Treatment: Do not restore without further consideration. 1. Separate teeth and restore only if cavitation is revealed 2. If not possible to separate, restore only if radiolucency extends fully 1/3 through dentine 3. Otherwise, do not restore because it is more likely than not that the approximate surface is not cavitated and lesion progression could be arrested or has already arrested 4. Implement preventative strategy to • Arrest active lesions • Remineralise lesions • Maintain arrester lesions |
|
|
Radio Code 5 |
Inner 2/3 of dentine Treatment: Restore now |

Fluoride Varnish - Duraphat 1) What is the concentration of Fluoride in Duraphat? 2) What is the optimal dosage of F+ in Duraphat for Primary, Mixed and Permanent Dentition? 3) What is the max dosage for Duraphat? 4) What are indications for duraphat use? 5) what are the contraindications of duraphat? 6) What is the mechanism of Duraphat? |
1) 22600 ppm 2) Primary - 0.25ml, Mixed - 0.4, Perm - 0.75 3) 5ml/ kg 4) ICDAS codes 1,2 and high caries risk pt. 5) bronchial asthma, hypersensitivity to colophony (Natural Resin) , Latex and sodium fluoride allergies, ulcerative gingivitis and stomatitis and contains ethanol (Avoid use in pregnant or lactating women). 6) Forms Calcium Fluoride upon contact with enamel. |
|
|
Dentine Conditioner 1) What are the ingredients of dentine conditioner? 2) Why do we use dentine conditioner? 3) How long do we leave dentine conditioner before washing and drying? |
1) 10% poly-acrylic acid, 90% distilled water 2) To remove saliva, food debris, blood and smear layer to open up enamel tubules. 3) 20 seconds |
|
|
Lining - Fuji LC bond or Vitrebond 1) When do we use Lining? 2) Why do we use Linings? 3) What surfaces do we apply Lining on? 4) How long do we cure lining for? |
1) We use Lining before a composite restoration 2) Linings is used to cover/ protect the dentinal tubules so medicaments don't seep through towards the pulp. etch cannot be placed directly on dentine as it is an acid and will cause sensitivity. 3) ON DENTINE - across pulpal floor and sometimes on axial wall of class 2. 4) 20 seconds |
|
|
Base Fuji II or Fuji IX 1) When do we use a base? 2) Why do we use a base? 3) What surfaces do we apply the base on? 4) How long do we cure base for? 5) When do we use open and closed sandwich technique? |
1) Irregular or rough floors, deep cavities 2) To make up for lost dentine and to seal dentinal tubules and pulpal protection. 3) On the exposed dentine (pulpal floor and axial wall). 4) 20 seconds 5) Open - used when there isn't enamel on gingival margin. Closed - When there is remaining enamel at gingival margin. |
|
|
Etchant 1) what is the composition of etchant? 2) What is the mechanism of etchant? 3) What procedures do we use etchant for? 4) How long do we leave etch before washing and drying? |
1) 37% orthophosphoric acid 2) Forms enamel rods which increase SA:V ratio which allows for resin tags to seep and adhere to tooth. 3) FS and composite resin restoration 4) 15 seconds optimum |
|
|
ScotchBond Adhesive 1) What is composition of Bond? 2) What is the mechanism of bond? 3) What procedures do we use bond for? 4) How long do we cure bond for? 5) Where do we place the bond? |
1) 2) 3) Composite resin 4) Leave 15 seconds to penetrate the etched surface and then cure for 20 seconds 5) The entire cavity prep |
