Which biologic agent is commonly used to promote periodontal regeneration by mimicking developmental proteins?

Answer: Enamel matrix derivative (Emdogain)

Enamel matrix derivative stimulates regeneration of periodontal tissues by mimicking tooth development.

What does the term 'guided bone regeneration (GBR)' primarily aim to achieve?

Answer: Increase bone volume using a barrier membrane

GBR uses a barrier membrane to exclude soft tissue and allow bone to fill a defect.

In implant prosthetics, what is a common cause of screw loosening in a screw-retained crown?

Answer: Inadequate preload or occlusal overload

Insufficient preload torque or excessive occlusal forces commonly lead to abutment screw loosening.

Which advanced imaging finding would most strongly contraindicate immediate implant placement?

Answer: Active periapical infection at the site

Active infection at the site compromises healing and contraindicates immediate placement.

What is the main goal of crown lengthening surgery?

Answer: Expose more tooth structure and restore biologic width

Crown lengthening removes bone and tissue to expose sound structure and re-establish biologic width.

Which sedation level allows the patient to respond purposefully to verbal commands while relaxed?

Answer: Moderate (conscious) sedation

In moderate sedation, patients remain responsive to verbal commands while comfortably relaxed.

What is the primary reason for using a rubber dam during advanced endodontic procedures?
