Preventive Dentistry flashcards for NEET MDS

24 of 50 cards from the Preventive Dentistry deck — real questions with worked answers.

1. Define preventive dentistry.

   The branch of dentistry concerned with promoting and maintaining oral health by preventing the onset, progression, and recurrence of dental diseases and abnormalities, rather than treating them after they occur.

2. What are the three traditional levels of prevention described by Leavell and Clark?

   Primary prevention (before disease onset), secondary prevention (early detection and prompt treatment), and tertiary prevention (limiting disability and rehabilitation).

3. Give an example of primary prevention in dentistry.

   Health education, water fluoridation, pit and fissure sealants, plaque control, and dietary counseling—measures applied before disease occurs to prevent its onset.

4. Give an example of secondary prevention in dentistry.

   Early detection and prompt treatment such as restoration of incipient caries, scaling for early gingivitis, and screening to catch disease early.

5. Give an example of tertiary prevention in dentistry.

   Rehabilitative measures like dentures, implants, and prostheses to restore function and limit disability after disease has caused damage.

6. What are the five levels of prevention in Leavell and Clark's expanded model?

   Health promotion, specific protection (both primary), early diagnosis and prompt treatment, disability limitation (secondary), and rehabilitation (tertiary).

7. Under which level of prevention does water fluoridation fall?

   Primary prevention—specifically 'specific protection'.

8. What is the optimal concentration of fluoride in community water fluoridation?

   Traditionally 0.7–1.2 ppm; the current recommended optimal level (US PHS 2015) is 0.7 ppm.

9. Who first demonstrated the link between fluoride and reduced caries, and where was the first fluoridated city?

   H. Trendley Dean established the relationship; Grand Rapids, Michigan (1945) was the first city to artificially fluoridate its water supply.

10. What is dental fluorosis and what causes it?

    A developmental hypomineralization/mottling of enamel caused by excessive fluoride ingestion (above optimal) during the period of enamel formation (tooth development).

11. What index is used to measure the severity of dental fluorosis?

    Dean's Fluorosis Index (categories: normal, questionable, very mild, mild, moderate, severe).

12. By approximately what percentage does community water fluoridation reduce dental caries?

    Roughly 25% reduction in caries across the lifespan (historically cited as 40–60% before widespread topical fluoride use).

13. What is the Halo or diffusion effect of water fluoridation?

    The caries-reducing benefit experienced by people living in non-fluoridated areas due to consumption of foods and beverages processed in fluoridated communities.

14. State the Stephan curve and its significance.

    A graph of plaque pH over time after a sugar exposure; pH drops below the critical value (~5.5) within minutes due to acid production and takes 30–60 minutes to recover. It shows when demineralization occurs.

15. What is the critical pH for enamel demineralization?

    Approximately 5.5 (the pH below which hydroxyapatite begins to dissolve).

16. What is the primary mechanism by which topical fluoride prevents caries?

    It promotes remineralization and forms fluorapatite (more acid-resistant than hydroxyapatite), inhibits demineralization, and inhibits bacterial enzymes/metabolism.

17. What is the fluoride concentration in professionally applied APF gel?

    1.23% acidulated phosphate fluoride (APF), equivalent to about 12,300 ppm fluoride.

18. What fluoride concentration is found in fluoride varnish and how often is it applied?

    5% sodium fluoride (22,600 ppm, ~2.26% F); typically applied 2–4 times per year for high-risk patients.

19. What is the recommended fluoride concentration in adult toothpaste?

    1000–1500 ppm fluoride (commonly as sodium fluoride or sodium monofluorophosphate).

20. What is the probable toxic dose (PTD) of fluoride?

    5 mg F per kg body weight—the dose at or above which toxic signs/symptoms appear and emergency treatment is warranted.

21. What is the certainly lethal dose (CLD) of fluoride for an adult?

    Approximately 32–64 mg F per kg body weight (commonly cited as 5–10 g of sodium fluoride for a 70 kg adult).

22. What is the first-aid management for acute fluoride toxicity?

    Induce vomiting, give milk or calcium/magnesium-containing antacids to bind fluoride, and seek emergency medical care; calcium gluconate for severe cases.

23. What are pit and fissure sealants and on which surfaces are they used?

    Resin or glass-ionomer materials placed in the pits and fissures of occlusal (and sometimes buccal/lingual) surfaces of teeth to provide a physical barrier against caries-causing bacteria and food.

24. What is the most important step ensuring retention of resin-based pit and fissure sealants?

    Adequate acid etching and complete moisture control (isolation/dryness)—saliva contamination is the leading cause of sealant failure.
