1) Merrifield and Orban
2) Merrifield and Kirkland

ANSWER. 3 (Kirkland and Orban #1 and #2)
Gingivectomy is a surgical procedure that involves the removal of a portion of the gingiva to eliminate periodontal pockets and create a more aesthetic appearance of the gingiva.
Several types of knives can be used in gingivectomy, but the most commonly used knives are the Kirkland knife and the Orban knife.
In gingivectomy, the Kirkland knife is typically used to make initial incisions in the gingiva, while the Orban knife is used to remove the excess tissue. Kirkland and Orban #1 and #2 are the most commonly used knives in gingivectomy.
The Merrifield knife is another type of surgical knife that is used in periodontal surgery, but it is not commonly used in gingivectomy. It is a small, straight knife with a pointed tip, and it is designed for delicate incisions in soft tissue.
1) Grade 3 defect is clinically visible.
2) Grade 1 can be visible radiographically as radiopaque.
3) In Grade 4 inter-radicular bone is completely lost.
4) In Grade 2 bone is attached to the dome of the furcation.
ANSWER. 1 (Grade 3 defect is clinically visible.)
The statement that is incorrect for furcation defect is "Grade 3 defect is clinically visible." In fact, Grade 3 furcation defect is not clinically visible and can only be detected by using a periodontal probe. The other statements are correct:
GLICKMAN CLASSIFICATION
Grade I: Incipient lesion. Suprabony pocket and slight bone loss in the furcation area.
Grade II: Loss of interradicular bone and pocket formation but a portion of the alveolar bone and periodontal ligament remain intact.
Grade III: Through-and-through lesion.
Grade IV: Through-and-through lesion with gingival recession, leading to a clearly visible furcation area
