What limitations should be considered when applying MID to permanent dentition?

• A. Larger deep lesions, heavy decay, or unfavorable restoration options may require conventional treatments; patient-specific factors matter.
• B. MID is always preferred for permanent teeth
• C. MID never applies to permanent dentition
• D. Esthetic concerns are the only consideration

Answer: (A)

Minimal intervention dentistry in permanent teeth is effective for early or small lesions and aims to preserve tooth structure through sealing and remineralization. However, its application has limits. In permanent dentition, larger deep lesions, extensive decay, or situations where a minimally invasive restoration cannot provide adequate seal, retention, or function often require conventional treatments such as more extensive fillings, crowns, or endodontic or surgical approaches. Other factors to weigh include the patient’s caries risk, ability to maintain oral hygiene, moisture control during treatment, tooth vitality, occlusion and esthetic demands, available restorative options, and the patient’s preferences or finances. Therefore, larger deep lesions, heavy decay, or unfavorable restoration options may necessitate conventional treatments, with patient-specific factors guiding the final decision.
