What is the aim of minimally invasive dentistry?

• A. Complete removal of all decay before restoration
• B. Preservation of as much of the natural tooth structure as possible
• C. Maximizing the use of new restorative materials regardless of tooth structure
• D. Extending preparation margins to inconsequential areas

Answer: (B)

Preserving as much natural tooth structure as possible is the guiding aim. In minimally invasive dentistry, the focus is on conserving tooth mass, using conservative cavity designs, selective caries removal, and adhesive restorations that seal and reinforce rather than aggressively remove tissue. This approach helps maintain the tooth’s strength, reduces the risk of fracture, and often allows remineralization of minor lesions. Pushing for complete removal of all decay before restoration can undermine tooth integrity and isn’t aligned with conserving structure. By prioritizing conservation, the treatment supports long-term function and vitality of the tooth.
