🪥 Oral Hygiene Instructions: Simple Advice, Big Clinical Impact! 🦷
“Brush twice a day” is good advice—but effective oral-hygiene instruction goes much further.
For the INBDE, remember that oral hygiene must be individualized, demonstrated and reassessed. The best technique is not simply the most popular one; it is the one suited to the patient’s periodontal condition, dexterity, appliances and interdental anatomy.
✅ THE 2–2–1 RULE
🪥 Brush 2 times daily
⏱️ Brush for approximately 2 minutes
🧵 Clean interproximally once daily
Use a soft-bristled toothbrush with fluoride toothpaste. Aggressive horizontal scrubbing should be avoided because it can traumatize the gingiva and contribute to cervical abrasion.
🔍 MODIFIED BASS: THE INBDE FAVORITE
The Modified Bass technique is particularly useful for cleaning the gingival margin and sulcular area.
How is it performed?
• Position the bristles at a 45° angle toward the gingival sulcus
• Apply gentle pressure
• Use short vibratory back-and-forth strokes
• Roll or sweep the bristles coronally
📌 Exam pearl: Modified Bass is commonly recommended for patients with gingivitis or periodontitis.
🦷 MATCH THE TECHNIQUE TO THE PATIENT
🔹 Modified Bass: Gingival-margin and sulcular plaque
🔹 Charters: Orthodontic appliances, fixed prostheses and postsurgical areas
🔹 Fones: Young children or patients who need a simple circular technique
🔹 Powered toothbrush: Limited dexterity or consistently poor plaque control
The toothbrush should be replaced when the bristles become frayed—commonly every 3–4 months.
🧵 TOOTHBRUSHING ALONE IS NOT ENOUGH
A toothbrush cannot effectively clean all proximal surfaces.
The correct interdental aid depends on the embrasure:
✅ Tight contacts: Dental floss
✅ Open embrasures: Interdental brushes
✅ Fixed bridges or orthodontic appliances: Floss threaders or superfloss
✅ Furcations or isolated difficult areas: End-tufted brush
For flossing, adapt the floss into a C-shape around each tooth and gently move it beneath the gingival margin. Simply snapping floss through the contact does not adequately clean the proximal surface.
🦷 FLUORIDE TOOTHPASTE IN CHILDREN
Brushing should begin when the first primary tooth erupts.
👶 Under 3 years: A rice-grain smear of fluoride toothpaste
🧒 Ages 3–6 years: A pea-sized amount
👨👩👧 Parents should supervise and assist until the child can brush effectively and spit reliably.
After brushing, the patient should spit out the excess toothpaste. Avoiding vigorous rinsing helps maintain topical fluoride contact with the teeth.
🧴 WHAT ABOUT MOUTHRINSES?
Mouthrinses are adjuncts, not replacements for brushing and interdental cleaning.
• Fluoride rinse → Additional caries prevention in selected high-risk patients
• Chlorhexidine → Short-term plaque control when prescribed
• Essential-oil or CPC rinse → May help reduce plaque, gingivitis and halitosis
⚠️ Chlorhexidine may cause:
• Brown staining
• Taste alteration
• Increased calculus formation
• Mucosal irritation
Therefore, prolonged unsupervised use should be avoided.
🎯 ORAL HYGIENE MUST BE PERSONALIZED
🦷 Periodontitis → Modified Bass + interdental brushes
😁 Orthodontic patient → Careful brushing around brackets + interdental brush + fluoride
🦾 Limited manual dexterity → Powered toothbrush or modified handle
👵 Denture wearer → Clean the denture daily, clean oral tissues and usually remove the denture at night
💧 Xerostomia or high-caries risk → Enhanced fluoride exposure, hydration and dietary counseling
🧑⚕️ THE BEST TEACHING METHOD: TELL–SHOW–DO
1️⃣ Tell the patient what to do and why
2️⃣ Show the technique using a model or mirror
3️⃣ Ask the patient to perform it
4️⃣ Correct mistakes and reinforce the technique at recall visits
Plaque-disclosing agents are especially useful because they allow patients to see the areas they routinely miss.
🔥 INBDE RAPID RECALL
Modified Bass → Sulcular plaque
Charters → Braces and postsurgical areas
Fones → Children
Floss → Tight contacts
Interdental brush → Open embrasures
Tell–Show–Do → Effective patient education
