Which of the following conditions gingivectomy is contraindicated:
1. Gingival sulcus beyond mucogingival junction.
2. Enlargement of the gingival.
3. Papillary enlargement.
4. Enlargement due to acute systems disease.
Periodontics
Answer: 1
Gingivectomy is a surgical procedure used to remove excess gingival tissue. It is typically performed when the enlargement of the gingival tissue is due to chronic inflammation or other local factors. However, if the enlargement is caused by an acute systemic disease, the surgical intervention could potentially exacerbate the underlying condition or lead to complications.
Secondary occlusal traumatism is least likely to be associated with
1. inflamed gingiva
2. bruxism
3. tooth mobility
4. migration of teeth
Periodontics
Answer: 1
Secondary occlusal trauma primarily relates to occlusal discrepancies or effects
on tooth mobility due to periodontal attachment loss rather than localized
gingival inflammation alone.
Not a contributing factor for ANUG
1. Pericoronal flap
2. Poor oral hygiene
3. Smoking
4. Aphthous ulcers
Periodontics
Answer: 4
Aphthous ulcers are not a contributing factor for ANUG.
The most important objective in equilibrating the natural dentition is to
1. ensure balance in eccentric movements
2. narrow the occlusal table
3. achieve a more favorable distribution of occiusal forces
4. eliminate open contacts and prevent food impaction
Periodontics
Answer: 3
Equilibration aims to distribute occlusal forces evenly across the dentition to
prevent excessive stress on individual teeth, thereby reducing the risk of
mobility, wear, and periodontal issues.
Site specific characteristic in oral cavity is not seen in which disease
1. Herpetic gingivostomatitis
2. ANUG
3. Diphtheria
4. Desquamative gingivitis
Periodontics
Answer: 1
Site-specific characteristics are not seen in herpetic gingivostomatitis.
At 6-years-age interdental papillary necrosis, ulceration, pain, bleeding and pseudomembrane formation is seen in
1. Herpetic gingivostomatitis
2. ANUG
3. Erythema multiforme
4. Streptococcal gingivostomatitis
Periodontics
Answer: 2
At 6 years of age, interdental papillary necrosis, ulceration, pain, bleeding, and pseudomembrane formation is seen in ANUG.
When electrosurgery is correctly employed to prepare gingival tissues for making impressions, it will
1. Permanently alter the contour of gingival tissues
2. Reduce the gingival height
3. Remove a thin layer of crevicular gingival tissue
4. None of the above
Periodontics
Answer: 3
When electrosurgery is correctly employed to prepare gingival tissues for making impressions, it removes a thin layer of crevicular gingival tissue.
Gore Tex membrane is used during reattachment procedures to
1. Prevent osseous regeneration
2. Prevent connective tissue attachment
3. To prevent formation of long junctional epithelium
4. All of the above
Periodontics
Answer: 3
Gore Tex membrane is used during reattachment procedures to prevent the formation of long junctional epithelium.
