Maintaining good oral hygiene practices, such as regular brushing and flossing, is the most effective way to prevent periodontal disease, as it reduces plaque accumulation and gingival inflammation.

Tap for Question

Answer

The most effective method of preventing periodontal disease in the general population is
1. oral hygiene
2. balanced diet
3. fluoride therapy
4. analgesics and antibiotics

Gingival hyperplasia, or the overgrowth of gum tissue, is commonly caused by chronic inflammation, certain medications like nifedipine, and hereditary conditions.

Chronic inflammation is a frequent cause, often resulting from poor oral hygiene.

Nifedipine therapy is a well-known example of medication-induced gingival enlargement.

Hereditary fibromatosis is a genetic condition that causes significant gum overgrowth.

Faulty tooth brushing, particularly overly vigorous brushing, is a primary cause of gingival recession (the wearing away of gum tissue), not hyperplasia.

Tap for Question

Answer

Hyperplastic gingiva is found in all of the following conditions except
1) Chronic inflammation
2) Nifedipine therapy
3) Hereditary firbromatosis
4) Faulty tooth brushing

Tap for Question

Answer

Instrumentation zone in periodontal therapy is
1. The portion of the tooth where calculus (or) necrotic cementum is found
2. CE junction
3. Exposed root surfaces
4. Deep periodontal pocket

#4 Periodontics

Gingivectomy is effective at eliminating false pockets (suprabony pockets).

The wound created during a gingivectomy heals by secondary intention.

The procedure involves removing a portion of the attached gingiva, which results in a decrease in its width.

Gingivectomy is a soft tissue procedure and does not provide access to the underlying alveolar bone; a flap surgery is required for bone access.

Tap for Question

Answer

Which of the following about conventional gingevectomy is untrue
1) Eliminate false pockets
2) Heal by secondary intention
3) Leads to decrease in width of attached gingiva
4) Provides accessibility to alveolar bone

#5 Periodontics

Gingival ablation is a surgical procedure that involves the removal of a portion of the gingival tissue. It is often used to treat conditions such as excessive gingival overgrowth or to improve the health of the gum tissue. Gingival recession due to friction from soft tissue, such as the tongue or cheek, is one possible outcome of this procedure. It does not inherently involve the removal of tissue due to tooth brushing, prominent roots, or hard tissue friction.

Tap for Question

Answer

The term gingival ablation indicates
1) Gingival recession due to faulty tooth brushing
2) Gingival recession accentuated by prominent palatal root
3) Gingival recession due to friction from hard root
4) Gingival recession due to friction from soft tissue

#6 Periodontics

Pre-treatment pocket depth (PD): 6 mm

Width of attached gingiva (WAG): 2 mm

Post-treatment WAG = Pre-treatment WAG + Pocket depth

2 mm + 2 mm (gain after healing) = 4 mm

Tap for Question

Answer

If pre-treatment pocket depth is 6 mm and width of attached gingival is 2 mm what will be the estimated width of attached gingiva after treatment
1. 2 mm
2. 4 mm
3. 5 mm
4. 6 mm

The apically positioned flap is a standard periodontal surgical procedure.

It increases clinical crown length by exposing more tooth surface.

It preserves the width of attached gingiva, which is a key advantage of the technique.

It is effective for pocket elimination or reduction.

It is more commonly performed on the buccal (cheek) and lingual (tongue) sides of the teeth, where there is sufficient attached gingiva.

Due to the anatomical limitations and lack of attached gingiva, it is generally contraindicated or less commonly done on the palatal (roof of the mouth) side.

Tap for Question

Answer

All are true of apically positioned flap except
1) Increases clinical crown length
2) Preserves the width of attached gingiva
3) Eliminates pockets
4) More commonly done on palatal side

A thin bluish line around the gingival margin is due to the absorption of lead.

Tap for Question

Answer

A thin bluish line around the gingival margin is due to the absorption of
1. Silver
2. Mercury
3. Drugs like tetracylines
4. Lead

#9 Periodontics

Subgingival calculus is often found in the lower anterior region due to the anatomy and position of the teeth.

Tap for Question

Answer

Subgingival calculus is highest in
1) Lower anterior region
2) Lower bicuspid region
3) Lower molar region
4) Upper molar region
