Which suture material is most appropriate for closing periodontal flaps due to its handling characteristics and controlled resorption?
Answer: 4-0 polyglycolic acid
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.
During an osseous resective surgery, a 'positive architecture' refers to which bone configuration?
Answer: Interdental bone higher than radicular bone
Positive architecture describes a configuration where interdental bone is coronal to radicular bone, which is physiologically normal and the goal of osseous recontouring.
The 'critical zone' of keratinized tissue recommended to maintain around implants is generally considered to be at least:
Answer: 2 mm
A minimum of 2 mm of keratinized mucosa around implants is widely recommended to facilitate plaque control and reduce peri-implant inflammation.
In a papilla preservation flap technique, the primary advantage over a conventional flap is:
Answer: Preservation of interdental papilla for better esthetics and closure
Papilla preservation flaps are designed to maintain the interdental papilla intact, which improves wound closure and esthetic outcomes, particularly in the anterior region.
When performing a gingivectomy, the external bevel incision is made at what angle to the long axis of the tooth?
Answer: 45 degrees
The external bevel incision in gingivectomy is directed at approximately 45 degrees to the tooth's long axis, creating a thin, tapered tissue margin.
Which of the following best describes the rationale for using a periodontal dressing (pack) after surgery?
Answer: Protects the wound and aids patient comfort during healing
Periodontal dressings protect the surgical wound from mechanical trauma and irritants, reducing discomfort without providing antibacterial sterilization.
A modified Widman flap differs from a full-thickness mucoperiosteal flap primarily in that it:
Answer: Employs an inverse bevel incision with minimal tissue removal and intimate flap adaptation
The modified Widman flap uses an inverse bevel incision to excise the pocket epithelium while preserving maximum bone coverage and allowing close flap readaptation.
