Which statement aligns with minimally invasive dentistry regarding restoration when restoration is necessary?

• A. Extensive restoration of cavitated lesions is preferred
• B. Minimal restorative intervention for cavitated lesions
• C. Delay restoration as long as possible
• D. Use only indirect restorations

Answer: (B)

Minimally invasive dentistry aims to preserve as much natural tooth structure as possible and to intervene with the least invasive method that still protects the tooth and stops disease from progressing. When restoration becomes necessary, the best approach is to perform minimal restorative intervention for cavitated lesions. This means removing only what is necessary and using techniques and materials that conserve remaining tooth structure, such as selective caries removal and direct, adhesive restorations when appropriate, or other conservative methods that arrest progression rather than overhauling the tooth. The idea is to restore function and integrity while keeping the tooth as intact as possible, rather than pursuing extensive reconstruction. Delaying restoration or insisting on only indirect restorations or extensive removal would go against that preservative, conservative philosophy.
