Which instrument is specifically designed to remove calculus from furcation areas during periodontal surgery?
Answer: Younger-Good 7/8 curette
The Younger-Good 7/8 curette has an angulated shank that allows access to furcation areas and interproximal surfaces during surgical debridement.
In guided bone regeneration (GBR), the primary function of the membrane is to:
Answer: Exclude epithelial and connective tissue cells from the regenerating space
GBR membranes act as barriers to prevent fast-proliferating epithelial and connective tissue cells from occupying the space needed for slower bone-forming cells.
After a free gingival graft, the graft undergoes 'plasmatic circulation' during approximately which time period?
Answer: 24–72 hours
During the first 24–72 hours, the graft survives via plasmatic diffusion from the recipient bed before revascularization (inosculaton) occurs.
The 'trap door' or 'tunnel' technique for subepithelial connective tissue grafting is advantageous primarily because:
Answer: It avoids a releasing incision, preserving papillary blood supply
The tunnel technique avoids vertical releasing incisions, maintaining intact papillary blood supply and reducing scar formation while covering multiple recession defects.
Semilunar coronally positioned flap is best indicated for which clinical situation?
Answer: Miller Class I or II recession with adequate keratinized tissue width
The semilunar technique is appropriate for shallow Miller Class I or II defects where adequate keratinized tissue exists, as it does not increase the zone of keratinized tissue.
Which of the following local anesthetics is most commonly used for periodontal surgery due to its vasoconstrictive properties prolonging duration?
Answer: 2% lidocaine with 1:100,000 epinephrine
2% lidocaine with 1:100,000 epinephrine provides reliable anesthesia for 60–90 minutes and reduces surgical bleeding via vasoconstriction, making it the standard for periodontal surgery.
When placing an implant in immediate extraction socket, which factor most increases the risk of failure?
Answer: Presence of active periapical or periodontal infection at the extraction site
Active infection at the implant site is a contraindication for immediate placement, as bacteria compromise osseointegration and significantly increase implant failure risk.
