Histologic evaluation of gingival response to an electrosurgical blade.

Lateral heat production during the use of electrosurgical procedures in the oral cavity causes denaturation of the connective tissue adjacent to the incision line. This study evaluated the denatured zone following electrosurgery incision in dog gingiva with a traditional tungston wire electrode and a no. 15 surgical blade adapted for electrosurgery use. The effects of using a passive electrode during surgical procedures and using an "autosensor" circuit to control power adjustment were also evaluated. It was found that a surgical blade adapted for electrosurgery produces a zone of denatured tissue that is not statistically different from that produced with a wire electrode. Moreover, no differences were noted between incisions produced with manual power adjustment and those with power controlled by the "autosensor" circuit. A significantly wider zone of denatured tissue was produced when incisions were made without a passive electrode in place.

Incidence and indications for surgical management of phenytoin-induced gingival overgrowth in a cerebral palsy population.

Phenytoin-induced gingival overgrowth (PIGO) is a recognized side effect in many cerebral palsy patients using diphenylhydantoin (Dph) for the control of seizures. Severe degrees of gingival overgrowth can affect the patient's dentition by: 1) interference with normal masticatory function to the point of documented weight loss, 2) producing an ectopically erupting dentition to the point of poor occlusal development, and 3) producing an unattractive appearance, in those patients who appreciate their esthetics, to the point of lessened self-concept. The purpose of this investigation was to evaluate the management of a group of 142 patients, with various cerebral palsy diagnoses, as to the use of diphenylhydantoin for the control of seizures. If diphenylhydantoin was used, the presence, degree, and surgical management of PIGO was documented. Additionally, if surgical treatment was employed for removal of hyperplastic gingiva, the indications for outpatient treatment (no use of general anesthetic) or inpatient (hospital admission and use of a general anesthetic) were identified. A discussion of major indications of surgery and postoperative complications of all surgical procedures is provided.

Lasers in aesthetic dentistry.

This article focuses on lasers and aesthetic dentistry and their unique parallel in history from their early development to their present day usage and application. The demand for aesthetic dentistry has had a major impact not only on treatment planning but also on the choice of materials, techniques, and equipment. It is this demand that has married the use of lasers with aesthetic dentistry. A short literature review on the five basic laser types precedes the basic premise of smile design and its critical importance in attaining the desirable aesthetic end result. A short review on biologic width and biologic zone reinforces their importance when manipulating gingival tissue. Four case reports highlight the use of diode, erbium, and carbon dioxide lasers. The end results show the power of proper treatment planning and the use of a smile design guide when using these instruments and confirm a conservative, aesthetic treatment without compromising the health and function of the patients.

Marginal resection for carcinoma of the mandibular alveolus and gingiva where radiologically detected bone defects do not extend beyond the mandibular canal.

PURPOSE: The study goal was to investigate the adequacy of marginal resection of the mandibular bone in cases of squamous cell carcinomas of the lower alveolus and gingiva where the radiologically detected bone defect does not extend beyond the mandibular canal. PATIENTS AND METHODS: Sixty-two patients who have had a mandibulectomy performed with or without preoperative radiotherapy and chemotherapy were the study subjects. This retrospective study investigated the correlation between the preoperative radiographic appearance and histopathologic findings of the excised tissue. The results of the treatments were evaluated. RESULTS: In the cases with erosive bone defects, the extent of the bone involvement did not exceed the extent of the radiographically detected bone defects. However, in 7 (36.8%) of the cases with moth-eaten type bone defects, the extent of bone involvement exceeded the bone defects detected by radiography. Further, 10 of the 16 cases with no apparent bone defect showed apparent bone involvement by the tumors histologically. There were no differences in the 5-year cumulative survival rate between the marginal resection and segmental groups. CONCLUSIONS: Marginal resection was effective in controlling mandibular alveolus and gingival cancers when radiologically detected erosive bone defects did not extend beyond the mandibular canal. Marginal resection was inadequate when moth-eaten defects were radiologically detected, except when the bone defects were confined to the alveolar bone.

Maxillary lateral incisor implants: planning with the aid of orthodontics.

Implants are commonly used to replace congenitally missing lateral incisors in adolescent orthodontic patients. However, these restorations are often challenging for the orthodontist, surgeon, and restorative dentist. In some patients the space across the alveolar crest is too narrow to permit the surgeon to place the implant. Occasionally the root apices of the adjacent central incisor and canine are in close proximity. In other cases the ridge thickness could be inadequate and require augmentation. When the orthodontist opens the space, the papilla heights are adversely affected. Some adolescent patients have altered passive eruption after orthodontic treatment, which affects the level of the gingival margins. Finally, questions commonly arise regarding the appropriate age for implant placement in these young patients. If not addressed, these issues could compromise the aesthetics of the implant restoration. This article will use several clinical examples to discuss each of these 6 potential problems and provide guidelines for their solutions.

Facial distortion secondary to idiopathic gingival hyperplasia: surgical management and oral reconstruction with endosseous implants.

Little information exists regarding the surgical and oral reconstructive options for the patient with idiopathic gingival hyperplasia, especially with regard to endosseous implant placement and recurrence of the disease. The authors report a case of severe gingival enlargement and bone resorption involving the maxillary and mandibular arches in a 21-year-old female causing distortion of facial features. The etiology could not be established but the condition was exacerbated during pregnancy, causing chewing, speaking, and esthetic problems. The hyperplastic tissue and all the teeth were removed surgically, followed by immediate placement of 2 endosseous implants. Restoration of esthetics and function with a maxillary denture and mandibular overdenture were completed 3 months later. No disease recurrence was noted at the 6-month postoperative interval.

Clinical assessment of injuries in orthodontic movement of impacted teeth. II. Surgical recommendations.

Adverse effects on periodontal tissues have been associated with surgical techniques used to expose impacted teeth that are to undergo orthodontic tooth movement. The purpose of this study was to compare the effects on the periodontium of two of the more commonly used surgical techniques for labially impacted canines--(1) exposure of the entire labial aspect of the anatomic crown with total excision of all keratinized tissue (the window approach) and (2) a technique which exposes only 4 to 5 mm of the most superficial portion of the labial aspect of the cusp tip while maintaining 2 to 3 mm of keratinized tissue. Twelve patients were selected who had undergone comprehensive orthodontic therapy for a unilateral labial impaction of an upper canine, and who had the impacted canine surgically exposed with a window approach. This group's periodontal status after orthodontic therapy was compared to that of another group of twelve patients who had also undergone comprehensive orthodontic therapy for a unilaterally impacted labial upper canine but in whom the surgical exposure of the impacted tooth had been performed in a manner which preserved 2 to 3 mm of keratinized tissue on the labial aspect. The results indicated that the twelve subjects in whom the window approach had been used had statistically more gingival recession, gingival inflammation, and loss of attachment on the labial and labioproximal surfaces of the impacted teeth than the other group that had 2 to 3 mm keratinized tissue maintained after surgical exposure (p less than 0.05).
