Curettage involves removal of the inflamed soft tissue lining of the periodontal pocket.

Healing occurs by proliferation of epithelial cells from the adjacent gingival tissue.

Re‑epithelialization of the sulcus is usually complete within 1–2 weeks.

Connective tissue repair and maturation take longer (several weeks), but epithelial coverage is relatively rapid.

Bone graft procedures are most successful in treating narrow three-wall defects. These are defects that extend from the crest of the alveolar bone to the alveolar crest and involve only one surface of the tooth root. The success of a bone graft in such cases is due to the presence of three walls of intact bone that can provide stability and support for the graft material, allowing for predictable and effective regeneration of the missing bone tissue.

Weakening of support to adjacent teeth is a contraindication to resection of crestal bone.

Lobular capillary hemangioma (Pyogenic granuloma). 

Clinical : The description of a solitary, pedunculated, red nodule on a finger that started after a minor cut and bleeds easily is a classic presentation of a pyogenic granuloma (PG). Trauma is a common triggering factor, and the hands/fingers are frequent sites.
Histology: The key histological feature is a benign proliferation of capillaries in a lobular configuration, which is the defining characteristic of a lobular capillary hemangioma, the more accurate name for pyogenic granuloma. 

 Kaposi's sarcoma: This is a malignant vascular tumor typically associated with human herpesvirus 8 (HHV-8) infection, most commonly seen in immunocompromised individuals (e.g., HIV/AIDS patients). It does not typically present as a solitary, pedunculated nodule after a minor cut.

Keratoacanthoma: This is a variant of squamous cell carcinoma that presents as a solitary, dome-shaped nodule with a central, hyperkeratotic crater, typically in sun-exposed areas. Its histology and gross appearance are distinct from a lobular capillary hemangioma.

Glomus tumor: This is a rare, benign tumor originating from glomus body cells, usually found in the distal extremities, especially the nail bed. It is typically characterized by paroxysmal pain, cold sensitivity, and tenderness, which are not mentioned in the patient's presentation. Histologically, it shows sheets of uniform glomus cell

Juvenile periodontitis (now referred to as localized aggressive periodontitis) is characterized by localized bone loss and periodontal pockets, often affecting adolescents and young adults. The sudden drifting of teeth and the severity of bone loss in specific areas align with this diagnosis.

Craters in facial and lingual interdental bone are best eliminated by osseous regeneration procedures.

Maintaining good oral hygiene practices, such as regular brushing and flossing, is the most effective way to prevent periodontal disease, as it reduces plaque accumulation and gingival inflammation.

Phenytoin is a common cause of drug-induced gingival enlargement, affecting a significant percentage of patients who use it.
Calcium channel blockers, such as nifedipine and amlodipine, are also known to induce gingival overgrowth.
Acute myelocytic leukaemia (AML) is a systemic condition that can manifest orally with symptoms like gingival infiltration and enlargement.

Mucogingival surgery is indicated for conditions affecting the gingiva and underlying mucosa, such as insufficient attached gingiva or high frenal attachments. 


A three-wall bony defect, which involves the bone surrounding the tooth, is typically managed through regenerative periodontal procedures, not mucogingival surgery.

A conventional gingivectomy is a procedure designed to eliminate suprabony periodontal pockets by excising the gingival wall of the pocket. 

It effectively eliminates false pockets. 

The wound heals by secondary intention, meaning it heals from the bottom up. 

The procedure involves removing gingival tissue, which inherently leads to a decrease in the width of the attached gingiva.
