Use of the operating microscope in dentistry.

Microsurgery is a discipline of multiple surgical procedures performed with optical magnification and illumination. The operating microscope has recently been introduced in dentistry. Magnification improves the performance of fixed prosthodontic laboratory and clinical procedures. The operating microscope has dramatically improved endodontic nonsurgical perforation repair and periradicular surgery. The use of the operating microscope and microsurgical instrumentation has resulted in more-precise periodontal surgical procedures with less operative trauma and improved healing. Use of the operating microscope and microsurgical instrumentation is described.

A comparison of papillary retention versus full-thickness flaps with internal mattress sutures in anterior periodontal surgery.

Esthetic considerations pose therapeutic dilemmas in the selection of surgical techniques in anterior periodontal surgery. Two surgical techniques designed to maximize postoperative esthetics in the anterior regions are described. Changes in interdental papillary height are reported and compared at 1 year postoperative. This study discusses the surgical techniques, their advantages and disadvantages, and their indications. Since there is less risk of recession and more potential for gain in papillary height, the papillary retention procedure, when possible, may be the procedure of choice in anterior regions.

Connective-tissue root coverage using microsurgery.

Use of the operating microscope and microsurgical instrumentation has made possible modifications in conventional root coverage procedures that eliminate vertical incisions, papillary elevation, and secondary intention wound healing. Greater precision in incisions and suturing done with microsurgery allows clinicians to obtain predictable root coverage with more aesthetic postoperative results and reduced patient discomfort.

An autogenous gingival graft technique.

This paper discusses a technique for root coverage using autogenous free gingival grafts. Twenty-two patients who had gingival recession on facial tooth surfaces were studied. The patients underwent surgical treatment, and pretreatment and posttreatment average probing depths for the distal, facial, and mesial tooth surfaces were compared. There was a general decrease in recession for all surfaces. Recession levels tended to remain stable for the duration of the study. There was a slight increase in recession on midfacial surfaces at 4 years that was not statistically significant.

Recurrent peripheral odontogenic fibroma of the attached gingiva: a case report.

Peripheral odontogenic fibroma is an uncommon, benign, unencapsulated, exophytic gingival mass of fibrous connective tissue covered with a surface epithelium. Odontogenic epithelium and mineralized material may be found in the mass. A case is reported of a lesion that recurred in the attached gingiva following initial excision. Differential diagnosis of exophytic gingival lesions and post-operative management are also discussed.

Treatment of periodontal disease in a patient with Turner's syndrome. A case report.

This case report describes a patient with Turner's syndrome receiving systemic androgen therapy who experienced marked gingival enlargement, bleeding, and discomfort. Turner's syndrome and its treatment are discussed. The literature pertaining to sex hormones and their role in affecting periodontal disease is reviewed. The patient was treated with full mouth gingivectomy and 2-week recall visits for a period of 2 months consisting of oral physiotherapy instructions, scaling, and topical fluoride application. She was then placed on 1-month recall for the next 4 months. This mode of therapy was effective in treating severe gingival hyperplasia in a patient receiving systemic androgen therapy.

Dental drugs and anaphylactic reactions. Report of a case.

The patient described here experienced an acute anaphylactic reaction after receiving parenteral lidocaine, oral aspirin, codeine, and penicillin following routine dental treatment. The patient had taken all of the drugs previously with no untoward effects. The incidence and mechanisms of drug-induced hypersensitivity reactions are discussed. The importance of monitoring the patient following drug administration, even in the case of a negative medical and drug history, is discussed.
