Gingival Curettage • Definition : • The term "gingival curettage" implies directing an operative instrument against the gingival wall of the periodontal pocket in order to remove the ulcerated epithelium covering the sulcus. 1. Gingival Curettage • The curettes is used to scraping of the gingival wall of a periodontal pocket to separate diseased soft tissue. 1. Gingival Curettage • TYPES 1. Gingival Curettage • II. Surgical curettage, • III. Chemical curettage, • IV. ultrasonic curettage. • V. Laser Tx 1. Gingival Curettage • INDICATIONS 1. ? 1. Gingival Curettage • However, the need for curettage to eliminate the inflamed granulation tissue appears to be questionable. 2. Excisional new attachment procedure (ENAP) • A surgical procedure in which the sulcular and junctional epithelium is resected. The aim of the procedure is to remove the diseased tissue and allow healing of the dentogingival and periodontal attachments. 2. Excisional new attachment procedure (ENAP) • advantages over traditional subgingival curettage is the definitive, clean excision of the junctional epithelium and the subjacent tissue with a greater probability of new clinical attachment 2.

Long-Term Uncontrolled Hereditary Gingival Fibromatosis: a Case Report
Long-term Uncontrolled Hereditary Gingival Fibromatosis: A Case Report Abstract Hereditary gingival fibromatosis (HGF) is a rare condition characterized by varying degrees of gingival hyperplasia. Gingival fibromatosis usually occurs as an isolated disorder or can be associated with a variety of other syndromes. A 33-year-old male patient who had a generalized severe gingival overgrowth covering two thirds of almost all maxillary and mandibular teeth is reported. A mucoperiosteal flap was performed using interdental and crevicular incisions to remove excess gingival tissues and an internal bevel incision to reflect flaps. The patient was treated 15 years ago in the same clinical facility using the same treatment strategy. There was no recurrence one year following the most recent surgery.

This paper presented two cases of generalized and severe HGF in siblings without any systemic illness. HGF was confirmed based on family history, clinical and histological examination. Management of both the cases was done conservatively. Quadrant wise gingivectomy using ledge and wedge method was adopted and followed for 12 months. The surgical procedure yielded functionally and esthetically satisfying results with no recurrence. KEYWORDS: Gingival enlargement, Hereditary, homozygous, Gingivectomy AA swollen gums.

Literature Review
LITERATURE REVIEW PERIODONTAL ANATOMY The tissues which surround the teeth, and provide the support necessary for normal function form the periodontium (Greek peri- “around”; odont-, “tooth”). The periodontium is comprised of the gingiva, periodontal ligament, alveolar bone, and cementum. The gingiva is anatomically divided into the marginal (unattached), attached and interdental gingiva. The marginal gingiva forms the coronal border of the gingiva which surrounds the tooth, but is not adherent to it. The cemento-enamel junction (CEJ) is where the crown enamel and the root cementum meet. The Marginal gingiva in normal periodontal tissues extends approximately 2mm coronal tothe CEJ. Microscopically the gingiva is comprised of a central core of dense connective tissue and an outer surface of stratified squamous epithelium. The space between the marginal gingiva and the external tooth surface is termed the gingival sulcus. The normal depth of the gingival sulcus, and corresponding width of the marginal gingival, is variable. In general, sulcular depths less than 2mm to 3mm in humans and animals are considered normal1. Ranges from 0.0mm to 6.0mm 2 have been reported.. The depth of a sulcus histologically is not necessarily the same as the depth which could be measured with a periodontal probe. The probing depth of a clinically normal human or canine gingival sulcus is 2 to 3 mm2 1. Attached gingiva is bordered coronally by the apical extent of the unattached gingiva, which is, in turn, defined by the depth of the gingival sulcus. The apical extent of the attached 1 gingiva is the mucogingival junction on the facial aspect of the mandible and maxilla, and the lingual aspect of the mandibular attached gingiva.

Gingival fibromatosis affects only the masticatory mucosa and does not extend beyond the muco-gingival junction. This article describes an unusual case of hereditary gingival fibromatosis with delayed eruption of permanent teeth in an 11 year-old girl and her younger sibling. The patient presented with severely enlarged gingival tissues affecting both arches and multiple retained deciduous. Most of the permanent teeth were not erupted. She had no associated symptoms to suggest any syndrome but there was family history of similar disorder with father and paternal aunt.
