Provides Oral Hygiene Instruction
Teach, don't lecture
Oral hygiene instruction is a communication skill as much as a clinical one. The exam tests whether you can assess, individualize, demonstrate, and follow up. Start with an assessment: existing plaque and calculus, gingival condition, restorations, orthodontic appliances, dexterity, and motivation. Then tailor the recommendation rather than reciting a standard script.
Concepts to master
- Toothbrushing: a soft-bristled brush, angled about 45 degrees toward the gingival margin, with short vibratory strokes; the modified Bass technique is the standard taught for most adults.
- Interdental cleaning: floss for tight contacts, interdental brushes for open embrasures and around orthodontic hardware, and water flossers as an adjunct, not a replacement.
- Dentifrices: fluoride is the active anti-caries ingredient; whitening and sensitivity products are cosmetic or comfort adjuncts.
- Demonstration and teach-back: show on a model, have the patient perform, and confirm understanding.
- Reinforcement: short, specific goals beat a long list; document what was taught.
Traps
Questions often present a patient with a fixed bridge or implants and ask for the best aid. Answer with what reaches the specific surface: floss threaders or interdental brushes under a bridge, not a powered brush alone. Another trap conflates plaque control with calculus removal: patients cannot remove calculus, only a clinician can. Also watch for questions implying a mouthrinse replaces mechanical cleaning; it does not.
Rule of thumb
Recommend the tool that physically reaches the surface at risk. Identify the site, then name the aid. If an answer names a general product without linking it to a specific surface, it is usually the distractor.
