Atraumatic Restorative Treatment

What is the primary advantage of using hand instruments in the Atraumatic Restorative Treatment (ART) approach?

• Faster caries removal

• Lower risk of pulp exposure

• Conservation of tooth structure

• Increased wear resistance of restorations

Which material is most commonly used for restorations in ART due to its chemical bonding with both enamel and dentine?

• Composite resin

• Glass ionomer cement

• Amalgam

• Resin-modified glass ionomer

ART is indicated in all of the following situations except:

• Inaccessible cavities for hand instruments

• Small cavities involving dentin

• Patients with special health care needs

• Public health programs in remote areas

The release of which ion from glass ionomer cement in ART restorations helps prevent further caries progression?

• Calcium

• Fluoride

• Phosphate

• Magnesium

ART is contraindicated in which of the following conditions?

• Small cavities involving only enamel

• Patients who are cooperative

• Low-income community settings

• Presence of a swelling or abscess

Which of the following is a limitation of ART?

• High cost of materials

• Requirement of complex dental equipment

• Hand fatigue during prolonged procedures

• Inability to provide pain relief

Which instrument is used to remove soft carious dentin in ART?

• Explorer

• Dental hatchet

• Spoon excavator

• Applier/carver

Which of the following is a key principle of ART?

• Use of local anesthesia in all cases

• Complete removal of caries using handpieces

• Cavity restoration with adhesive restorative materials

• Treating all cavities, regardless of accessibility

In which of the following scenarios is ART preferred over conventional restorative methods?

• When local anesthesia is mandatory

• In multi-surface restorations for all patients

• When high strength and wear resistance is essential

• In populations with limited access to electricity

What is the primary method used to control moisture during ART procedures?

• Cotton wool rolls

• High-speed suction

• Rubber dam isolation

• Air drying
