How does ICDAS-II facilitate decision-making in Minimally Invasive Dentistry?

• A. Proposes uniform restoration for all lesions.
• B. Measures plaque pH to decide treatment.
• C. Provides a standardized grading of caries severity from initial to cavitated lesions, guiding non-invasive vs minimally invasive treatment.
• D. Determines anesthetic technique.

Answer: (C)

At its core, this item is about how caries assessment guides treatment decisions in Minimally Invasive Dentistry. ICDAS-II provides a standardized, clinically practical grading of caries from initial, non-cavitated changes to cavitated lesions. This staging tells you exactly when to apply non-invasive measures (remineralization, fluoride therapies, sealants) and when to use minimally invasive approaches (sealing over early lesions, micro-invasive restorations) rather than defaulting to full restorations. Having a consistent scale also helps you communicate with patients and other clinicians and supports aiming to preserve tooth structure. It doesn’t involve measuring plaque pH, it doesn’t mandate uniform restorations for all lesions, and it doesn’t dictate anesthetic technique.
