Gingival Curettage

scraping of gingival wall of a periodontal pocket to separate diseased soft tissue

Scaling refers to removal of deposits from tooth/ root surface

Root Planing smoothening the root to remove infected and necrotic tooth surface


TYPES I. Gingival curettage: Consists of removal of inflamed soft tissue lateral to pocket wall a. Subgingival curettage: It is a procedure that is performed apical to epithelial attachment b. Inadvertent curettage: Curettage that is done unintentionally during scaling and root planing. II. Surgical curettage, III. Chemical curettage, IV. ultrasonic curettage. V. Laser Tx


INDICATIONS 1. In patients whom extensive surgery is contraindicated owing to systemic disease or psychologic problems. 2. Shallow pocket depths with an adequate width and thickness of gingival tissue. 3. It can be performed as a part of new attachment attempts in moderately deep intrabony pockets located in accessible areas. 4. Curettage can be performed on recall visits as a method of maintenance treatment for areas of recurrent inflammation. 5. In suprabony pockets which do not extend beyond the mucogingival junction.


CONTRAINDICATIONS 1. Presence of acute infections such as necrotizing ulcerative gingivitis (NUG). 2. Fibrous enlargement of gingiva such as phenytoin hyperplasia. 3. Extension of the base of the pocket apical to the mucogingival junction. 4. If the patient is medically compromised, the benefits versus the risks of the surgical procedure should be carefully weighed before commiting the patient to the procedure.


PROCEDURE Curettage can be accomplished as a open procedure with a gingival incision followed by root planing (ENAP) Basic Technique (With Curette)

Curettage can be accomplished as a closed procedure with a sharp curette or as an gingival incision followed by root planing (ENAP)

with a sharp curette or as an gingival incision followed by root planing (ENAP).


Excisional New Attachment Procedure (ENAP

Excisional New Attachment Procedure (ENAP)


Ultrasonic Curettage Sound energy absorbed at tissue junctions that take the form of heat, results in coagulation. The coagulated epithelium is then removed by mechanical action of the vibrations of ultrasonic instrument. Chemical Curettage Sodium sulphide, phenol, camphor, antiformin, and sodium hypochlorite have been used for chemical curettage. Solution applied for 1 minute. Then 5% citric acid solution is introduced into the pocket for 1 minute to neutralize the sodium hypochlorite. The coagulated tissue is then removed with a curette and pocket is flushed with saline to remove the remnants of the connective tissue. The extent of chemical penetration to the tissue cannot be controlled and thus, chemical curettage is discarded.


Laser Nd:YAG laser treatment HEALING AFTER CURETTAGE Gingival sulcus filled by blood clot immediately after curettage. Abundant polymorphonuclear leukocytes occupy the wound site. followed by rapid proliferation of granulation tissue.

Epithelium: Sulcular epithelium is restored between 2 to 7 days

junctional epithelium: as early as 5 days after curettage.

Connective tissue: Immature collagen fibers appear within 21 days.
