Viva Question and Answers related to the Gingiva!

1. Question: What is the gingiva?

 Answer: The gingiva is the soft tissue surrounding the teeth, covering the alveolar processes of the jaws and enclosing the necks of the teeth.

• Question: What are the functions of the gingiva?

 Answer: The gingiva protects the underlying structures of the teeth and provides a seal around them, preventing the entry of bacteria and foreign substances into the oral cavity.

• Question: What are the two main parts of the gingiva?

 Answer: The gingiva is divided into the free gingiva (unattached) and attached gingiva (adherent to the tooth and underlying bone).

• Question: What is the gingival sulcus?

Answer: The gingival sulcus is the shallow groove or crevice between the tooth surface and the free gingiva.

• Question: How does the gingiva attach to the tooth?

Answer: The gingiva attaches to the tooth via the junctional epithelium, which forms a collar-like structure at the base of the gingival sulcus.

• Question: What is the color of healthy gingiva?

Answer: Healthy gingiva is usually pink or coral pink, depending on the individual’s pigmentation.

• Question: What is the role of keratinized gingiva?

 Answer: Keratinized gingiva provides a protective barrier and resistance to mechanical and microbial insults.

• Question: What is the gingival margin?

 Answer: The gingival margin is the edge of the free gingiva surrounding the tooth. viva question and answers in Acute necrotizing ulcerative gingivitis

• Question: What are the common signs of gingival inflammation? Answer: Signs of gingival inflammation include redness, swelling, bleeding upon probing, and increased temperature.
