How does radiography integrate with MID decision-making?

• A. Radiographs are unnecessary in MID
• B. Radiographs help assess lesion depth, proximity to pulp, and restoration planning while avoiding unnecessary removal
• C. They only show tooth color
• D. They replace the need for clinical examination

Answer: (B)

Radiographs provide essential information about how far a carious lesion has progressed under the enamel and into dentin, and how close it is to the pulp. In Minimally Invasive Dentistry, that depth and pulpal proximity guide the plan so you can remove only what is necessary and choose conservative strategies—such as sealing the lesion or removing only affected dentin—rather than removing large amounts of sound tooth structure. They also support restoration planning by revealing proximal margins, existing restorations, and the tooth’s internal status, helping to design the restoration with minimal destruction while still protecting the pulp. Remember, radiographs are a valuable complement to clinical examination and tests, not a replacement, and they should be interpreted in the context of symptoms and other findings.
