In esthetic treatments, it is important to consider the arrangement of teeth and the relation between the teeth and soft tissues. A precise diagnosis and establishing an appropriate treatment plan is essential in an esthetic treatment of anterior maxillary teeth. For a fixed prosthesis to meet esthetic expectations, It is crucial to achieve symmetry and adequate proportions of the gingival contour around the crowns. To achieve an esthetic improvement and creating a favorable environment for gingival healing of a physiologic gingival contour, gingivectomy, crown lengthening and forced eruption can be applied to the appropriate site. All ceramics or porcelain laminate veneer can be selected for esthetic improvement of teeth contour and shade. In this case report, malposition of the remaining teeth made it hard to get an esthetic appearance. Gingivectomy, crown lengthening and provisional restoration insertion were performed before the final prosthesis fabrication to reform the gingival form. This case presents satisfying result esthetically and functionally.

Mucopolysaccharidosis (MPS) is a disorder of storage in which there is excessive accumulation of glycosaminoglycans (GAGs) from lysosomal enzyme defect. Lysosomal accumulation of GAGs eventually results in cell, tissue and organ dysfunction. This patient may manifest mental retardation and physical disorders. This clinical report presents a girl with MPS having severe gingival hyperplasia. Gingivectomy was performed under general anesthesia. The pediatric dentist must be aware of oral manifestations present in the MPS. The approach to dental management will require teamwork between the dentist and the patient's physician.

Idiopathic gingival hyperplasia is a rare condition of undetermined etiology. The enlargement is usually associated with the emergence of the teeth into the oral cavity and may regress after extraction. The enlarged gingiva may be primarily attributed to hyperplasia of the subepithelial layer that is relatively avascular and consists of densely arranged collagen bundles and numerous fibroblasts. The recommended time for treatment is after completion of eruption of permanent teeth. But the most important thing is the patient's psychological and esthetic needs. Lately, Schluger has proposed modified gingivectomy procedure with horizontal, internal beveled incision for thinning of the flap resulting in less pain and bleeding after treatment, minimal opportunity of infection. The purpose of this report is to document a case of 8-year-old girl who had registered in Dept. of Pediatric Dentistry of Seoul National University dental hospital for treatment of her gingival hyperplasia and delayed tooth eruption

Drug-induced gingival overgrowth is an abnormal increase of gingival tissues caused as a side effect of systemic medication. This report presents a severe case of valproate-induced gingival overgrowth combined with ulcerative and hemorrhagic lesions in a patient with Lennox-Gastaut syndrome. Considering the patient's limited cooperative ability, gingivectomy and excisional biopsy under general anesthesia were performed. The lesions were successfully treated without recurrence. When gingival enlargement does not subside with nonsurgical treatments, surgical procedure and excisional biopsy are to be performed. Postoperative management of oral hygiene is critical to prevent recurrence.

It is a relatively common clinical experience to see a impacted maxillary central incisor Most often, the central incisor is impacted labially. The labial impaction has been indicated as the most difficult to manage. The labial impactions have been found to be associated with mucogingival recession, reduced attached gingiva and periodontal pockets. For the successful treatment, clinicians should avoid loss of attached gingiva in surgical exposure. The most common methods of uncovering labially impacted maxillary anterior teeth are gingivectomy, apically positioned flap and closed eruption technique. If gingivectomy will not leave enough attached gingiva, then an apically positioned flap may be the treatment of choice. If the tooth is impacted in the middle of the alveolus or high in the vestibule near the nasal spine, the closed eruption technique may be the treatment of choice. Closed eruption technique was used in one case, apically positioned flap was used in two case. As the result in two cases of impacted maxillary central incisor, apically positioned flap provide the adequate width of attached gingiva. In case of impacted maxillary central incisor, through the clinical and radiologic examination to select correct surgical operation for reduce the complications.

Intrinsic discoloration of permanent anterior teeth is a continuing esthetic problem. Tetracycline ingested during amelogenesis has long been recognized as predisposing factor in intrinsic staining. Methods for restoring original tooth color have included (1) complete PFM crown coverage (2) porcelain laminate veneers (3) direct bonding of composite resin, and (4) bleaching. In the case of tetracycline-stained upper anterior teeth, We authors, obtained the satisfactory results by means of gingivectomy, preliminary bleaching and porcelain laminate veneer restoration.

This is a case report of idiopathic fibromatosis on the gingiva. The patient was a 25 years old male. In this case, we had a good result from surgical excision, combining the gingivectomy and split thickness flap operation.

Laser means "Light amplification by stimulated emission of radiation". Laser have unique characteristics according to wavelength. Wavelenth of Waterlase is 2780nm and it can be absorbed to water and hydroxyapatite. When laser is applied to some material, its temperature goes up due to laser's energy. But in dental treatment high temperature is not good for teeth. High temperature can make dental pulp and bone necrosis. Waterlase can be absorbed to water droplet, so when it burst, it can cut soft and hard tissue without raising temperature. so it is so proper to dental treatment.

Gingival fibromatosis is a non-inflammatory oral disease, characterized by slowly progress enlargement of the free and attached gingiva. Gingival fibromatosis may have familial tendency. Gingival enlargement usually begins with the eruption of the permanent dentition but can also develop with the eruption of the primary dentition. In this case, a 6-year-old female had gingival enlargement at birth. There was no familial, medical and pharmacologic history of gingival overgrowth. Treatment is gingivectomy with a rigorous program of oral hygiene. Recurrence of gingival fibromatosis may well be inevitable. Therefore there is no general aggrement as to the timing of surgical intervention. Generally the best time is when all the permanent teeth have erupted. However early intervention can improve oral function and esthetic and psychologic effect.

The use of laser in the treatment of soft tissue minimizes hemorrhage, provides better view of the operating field, and thereby minimizes operating time. Also, there will be far less post-operative swelling, pain and scar formation, and sterilizing effect are shown in some portions of the wound site. All these advantages of laser therapy contribute to its widespread use in the field of medicine and dentistry. Regarding such facts, we used CO2 laser of different watts in gingivectomy for white rats to compare initial healing process. For the control group, the least amount of output in performing gingivectomy(4watts) was offered, and for the experimental group, 6watts was given. Animals were sacrificed on the second, third days, 1 weeks, 2 weeks, and 3 weeks after operation, and their specimens were histologically analyzed. The following results were obtained: 1. Blood clot of small size was observed in both the control and experimental groups after two days, and no more thereafter. 2. In both the control and experimental groups, the inflammation zone size was the greatest after two days, and it decreased gradually to become almost invisble by the second week. The experimental group showed larger size of inflammation zone during second and third days: however, there was no difference after one week. 3. Granulation tissue in both the control and experimental groups showed gradual maturation with time, and by the second week, it was almost replaced by normal connective tissue. By the third week, complete healing pattern was observed. The experimental group showed larger granulation tissue than the control group until the third day, but there was no significant difference after one week. 4. In both the control and experimental groups, gingival epithelialization began on the second day. After one week, regeneration of rete peg and partial formation of junctional epithelium were observed: by the second week, keratinization of oral sulcular epithelium began, and it was completed by the third week.
