Question 1

Which suture material is most appropriate for closing periodontal flaps due to its handling characteristics and controlled resorption?

Accepted Answer

4-0 polyglycolic acid

Answer

Polyglycolic acid (Vicryl) sutures offer excellent knot security, predictable resorption over 3–4 weeks, and minimal tissue reaction, making them ideal for periodontal flap closure.

Question 2

During an osseous resective surgery, a 'positive architecture' refers to which bone configuration?

Accepted Answer

Interdental bone higher than radicular bone

Answer

Positive architecture describes a configuration where interdental bone is coronal to radicular bone, which is physiologically normal and the goal of osseous recontouring.

Question 3

The 'critical zone' of keratinized tissue recommended to maintain around implants is generally considered to be at least:

Accepted Answer

2 mm

Answer

A minimum of 2 mm of keratinized mucosa around implants is widely recommended to facilitate plaque control and reduce peri-implant inflammation.

Question 4

In a papilla preservation flap technique, the primary advantage over a conventional flap is:

Accepted Answer

Preservation of interdental papilla for better esthetics and closure

Answer

Papilla preservation flaps are designed to maintain the interdental papilla intact, which improves wound closure and esthetic outcomes, particularly in the anterior region.

Question 5

When performing a gingivectomy, the external bevel incision is made at what angle to the long axis of the tooth?

Accepted Answer

45 degrees

Answer

The external bevel incision in gingivectomy is directed at approximately 45 degrees to the tooth's long axis, creating a thin, tapered tissue margin.
