• A traumatic bone cyst is best treated by

• marsupialization
• enucleation of the cyst lining
• opening the cavity and packing open

D. opening the cavity and inducing bleeding - CORRECT ANSWER: D. opening the

cavity and inducing bleeding

1) marsupialization: Marsupialization is the surgical technique of cutting a slit into an abscess or cyst and suturing the edges of the slit to form a continuous surface from the exterior surface to the interior surface of the cyst or abscess. Sutured in this fashion, the site remains open and can drain freely. This technique is used to treat a cyst or abscess when a single draining would not be effective and complete removal of the surrounding structure would not be desirable.

2) enucleation: enucleation involves removal of all tissue (both hard and soft) involved in a lesion.

• The patient lacks an adequate band of attached gingiva on the facial surface on the

mandibular left 2nd premolar. This problem might be resolved through which of the following periodontal surgical procedures?

• Pedicle graft from the adjacent edentulous ridge
• Pedicle graft from the facial surface of the adjacent 1st premolar
• Free gingival graft from the palate - CORRECT ANSWER: A. Pedicle graft from the

adjacent edentulous ridge

• Free gingival graft from the palate
