What preventive measures are essential in MID?

• A. Only restorative treatment
• B. No preventive measures
• C. Fluoride therapy, oral hygiene instruction, diet counseling, and control of cariogenic factors
• D. Regular extractions

Answer: (C)

In Minimally Invasive Dentistry, preventing disease and maintaining natural tooth structure is the primary goal, so the essential approach combines chemical, educational, and lifestyle strategies. Fluoride therapy strengthens enamel and helps remineralize early lesions, while oral hygiene instruction reduces plaque biofilm that drives caries. Diet counseling addresses the frequency and type of carbohydrate exposure, lessening the cariogenic challenge to teeth, and actively controlling cariogenic factors—such as limiting fermentable sugars and managing factors like dry mouth—reduces ongoing risk. Together, these measures support remineralization, minimize lesion progression, and align with a conservative, preservation-focused mindset.

Restorative treatment alone doesn’t prevent new lesions and doesn’t change the patient’s risk factors; not applying preventive measures misses opportunities to halt disease early; and regular extractions remove teeth rather than prevent disease. Hence, the comprehensive set of preventive actions listed is the best fit for MID.
