The efficacy of three different surgical techniques in the management of drug-induced gingival overgrowth.

OBJECTIVES: The aim of the present study was to evaluate the efficacy of three different surgical techniques in both the management and effect upon rate of overgrowth recurrence of drug-induced gingival overgrowth (DIGO). MATERIALS AND METHODS: Two cohorts of patients who required surgical correction of their DIGO participated in the study. After baseline periodontal measures (plaque index, gingival inflammation and probing pocket depths), the patients underwent surgery. A split-mouth, crossover design was used to compare conventional gingivectomy with flap surgery (n=27), and conventional gingivectomy with laser excision (n=23). The main outcome variable was the rate of recurrence of DIGO following surgery. RESULTS: At 6 months, there was significantly less recurrence (p=0.05) in patients treated with laser excision, compared with those treated by conventional gingivectomy. The differences in rate of recurrence of DIGO were also reflected in changes in several periodontal parameters. Flap surgery offered no advantage over conventional gingivectomy with respect to the rate of recurrence. CONCLUSIONS: DIGO can be managed by a variety of techniques. Laser excision results in a reduced rate of recurrence.

Treatment and long-term follow-up of a patient with hereditary gingival fibromatosis: a case report.

This report addresses the complex nature of oral diagnosis, treatment and long-term case management in the hereditary form of recurrent gingival fibromatosis. Case management is discussed in relation to a 13-year-old girl who presented with recurrent, progressive gingival enlargement requiring consecutive periodontal and orthodontic treatment. The initial course of treatment included 4-quadrant gingivectomy with reverse bevel incisions, followed by orthodontics. Microscopic examination of the gingivectomy specimens supported the clinical diagnosis. Three years later, recurrence of the condition was observed in all quadrants. To facilitate orthodontic tooth movement and to achieve optimal esthetics, another full-mouth gingivectomy was performed. There was no recurrence of the condition a year later. It is recommended that patients with this condition be monitored closely after gingivectomy, so that the treatment requirements of localized areas can be addressed as needed.

Regeneration of gingiva following surgical excision. A clinical study.

The present clinical trial was carried out in order to analyze whether a zone of keratinized and attached gingiva may regenerate following surgical excision of the gingiva. In addition the alterations occurring in the position of the "soft tissue margin" and the clinical attachment level were assessed. 6 patients, scheduled for periodontal surgery in the canine-premolar regions of both quadrants of the lower jaw, participated in the trial. A Baseline examination performed prior to surgery comprised assessments at the buccal surface of the teeth of dental plaque, gingivitis, probing depth, clinical attachment level, position of the "soft tissue margin" and width of the zones of keratinized and attached gingiva. The entire zone of keratinized and attached gingiva was removed surgically using either a "gingivectomy" or a "flap-excision" procedure. In the "gingivectomy" procedure the wounded area was left to heal by second intention, while in the "flap-excision" procedure the alveolar mucosa was repositioned in a coronal position to achieve complete coverage of the surgically exposed alveolar bone. During healing the patients' oral hygiene status was carefully supervised. All parameters included in the Baseline examination were assessed at reexaminations performed 1, 3, 6 and 9 months following surgery. Already 1 month after surgery all "gingivectomy" units and 9 out of the 14 "flap-excision" units demonstrated presence of a zone of keratinized gingiva. At the final examination (9 months following surgery) all surgically treated buccal areas had regained a zone of keratinized gingiva. However, a zone of attached gingiva reformed less frequently. The examination performed 3 months after surgery revealed that the "soft tissue margin" and the clinical attachment level had become displaced in apical direction, 0.9 and 0.4 mm, respectively. Between the 3-month and the 9-month examinations, however, no further alterations were observed and the gingival units were healthy, independent of the presence or absence of attached gingiva or the width of the zone of keratinized gingiva.

Periodontal treatment of two siblings with juvenile hyaline fibromatosis.

BACKGROUND AND AIM: Juvenile hyaline fibromatosis (JHF) is an autosomal recessive disease that presents with multiple subcutaneous nodular tumours, gingival fibromatosis, flexion contractures of the joint and hyaline material accumulation in extracellular area. Recently, the causative gene for JHF, capillary morphogenesis protein 2 (CMG2) was identified. In this case report, periodontal status, treatment and follow-up together with histopathologic evaluation of gingival tissue specimens and mutation screening of two JHF cases are presented. CASE REPORTS: A 10-year-old female (case 1) and her 3-year-old brother (case 2) were first examined in our department with a complaint of gingival hyperplasia in 1991. Symptoms of the disease were detected in two of four siblings in the family. Several gingivectomy operations were carried out over 11 years with hygiene motivation and initial phase therapy. After the last gingivectomy operation in 2002, the patients were reviewed frequently. RESULTS AND CONCLUSIONS: Although there was linear marginal gingival inflammation, no remarkable enlargement was noted at last appointment. Histopathological findings showed increased amounts of subepithelial nodular connective tissue, thinned epithelial mucosa, separated inter-cellular bridges and decreased numbers of connective tissue cells in gingival tissue samples. Electron microscopic examinations supported the histopathological findings. Mutation screening of CMG2 demonstrated that the siblings were homozygous for a pathogenic missense mutation, V386F. Our clinical findings demonstrate that gingivectomy is useful and frequent periodontal visits are important for maintaining oral hygiene and decreasing growth rate of gingiva in JHF.

Mitotic response in basal cells of the crevicular epithelium to gingival surgery.

A total of 18 periodontal patients participated in this study. After initial preparation, a gingivectomy was performed on the lingual surfaces of posterior teeth with pockets ranging from 3 to 5 mm in depth. Control specimens were obtained at time of gingivectomy. Subsequently, the patients were divided into three groups (Group I, II, III). Each group contained three male and three female patients. The gingivectomy site was biopsied after surgery at 7, 14, and 28 days. The mean mitotic indices of the basal cell layer of the crevicular epithelium were obtained. At 0 day, the mean mitotic index was 6.6, increased to 11.4 at 7 days, and rose to a high value of 11.6 at 14 days. It was reduced to a value of 9.7 at 28 days. From our data, it appeared that the rise in mitotic activity which followed gingival injury did not fall to preoperative levels at 30 days postsurgery.
