What is the basic principle of Atraumatic Restorative Technique (ART) and in what scenarios is it particularly useful?

• A. Remove carious tissue with hand instruments and restore with high-viscosity glass ionomer cement; useful in low-resource settings, uncooperative patients, and where moisture control is difficult.
• B. Use rotary drills and composite resin
• C. Use full-coverage crowns
• D. ART is not suitable for primary teeth

Answer: (A)

The basic idea behind ART is to limit intervention to removing decayed tissue with hand instruments and then restoring the tooth with high-viscosity glass ionomer cement. This keeps the procedure atraumatic—no drill noise, less vibration, and often no anesthesia needed—while the glass ionomer bonds to dentin and releases fluoride to help protect against future decay. This approach shines in situations where resources are limited, moisture control is hard to maintain, or the patient is young, anxious, or uncooperative, such as field clinics or remote settings. It works well for primary teeth as well as for permanent teeth with shallow to moderate caries, providing a seal that preserves tooth structure without the need for more extensive drilling or complex restorations.
