[Comparative studies of the glycogen content in the gingiva in patients with periodontal disease and in experimental dogs].

Comparative examinations were carried out on the Glycogen content in the gingiva of patients suffering from parodontal disease as well as in dogs with experimental model of parodontal disease. The latter was obtained by stimulation of the mandibular nerve by means of a silk ligature. Thirty-five biopsies were taken from the patients, suffering from parodontal disease and eight - from 4 experimental dogs. The preparations were treated with periodic acid (PAS reaction).

The use of acellular dermal matrix allograft for the elimination of gingival melanin pigmentation: case presentation with 2 years of follow-up.

The most common cause of gingival pigmentation is the deposit of melanin in the basal layer of the oral epithelium. The presence of pigmentation does not constitute a pathology, and treatments including cryosurgery, Nd:YAG laser, gingival grafts, and removal of the epithelium in the pigmented area have been described in the literature. This case presentation illustrates the aesthetic treatment of bilateral gingival melanin pigmentation. The clinical results obtained using an acellular dermal matrix allograft were compared to the postoperative results of gingivoplasty in the same patient.

Periodontal treatment of an amalgam tattoo.

The amalgam tattoo can often result in an unsightly cosmetic appearance, especially in the maxillary anterior region. The predominant treatment for an amalgam tattoo is the free gingival graft, which also results in a poor cosmetic appearance. The authors would like to review the pathogenesis of the amalgam tattoo and present a new technique that leads to a pleasing cosmetic result.

The role of periodontal plastic microsurgery in oral facial esthetics.

Periodontal plastic microsurgery incorporates the use of a surgical dissecting microscope in an attempt to increase visibility, minimize trauma, and enhance surgical results. This paper will attempt to demonstrate how periodontal plastic surgery utilizing periodontal microsurgery could contribute in the role of soft tissue modification to enhance the smile and ideally allow for improved oral facial esthetics.

Gingival prostheses--a review.

Gingival replacement is often a component of comprehensive prosthodontics. Gingival prostheses may be fixed or removable and may be made from acrylics, composite resins, silicones or porcelain-based materials. Undercuts or dental attachments are used to secure removable prostheses, which are esthetically pleasing and easy to maintain. This paper describes several clinical situations in which gingival prostheses were used effectively.

Erbium:YAG laser application in the second phase of implant surgery: a pilot study in 20 patients.

PURPOSE: Conventional implant dentistry implies 2 surgical stages. In this context, pain is often present in the second stage, despite the fact that it is comparatively less aggressive for the patient. The present pilot study proposes application of Erbium:YAG (Er:YAG) laser for second-stage implant surgery. MATERIALS AND METHODS: Twenty patients were studied with a total of 50 implants in which osseointegration was complete. The subjects were divided into 2 groups: a control group (10 patients with 25 implants), subjected to conventional second-stage surgery; and a group of 10 subjects (also with 25 implants) treated with the Er:YAG laser at second-stage implant surgery. RESULTS: The use of Er:YAG laser obviated the need for local anesthesia and minimized postoperative pain and time needed before starting the second stage. With regard to surgical duration, quality of hemostasis, and success in implant treatment, no differences were reported. DISCUSSION: In the second stage of implant surgery, different types of laser have been used, taking advantage of their bacteridal effect; disadvantages arise from inducing damage to the implant surface and adverse thermal effects. CONCLUSION: The advantages afforded by laser treatment include technical simplicity, the possibility of obviating local anesthesia, absence of postoperative pain and edema, and complete tissue healing by day 5, thus facilitating rapid prosthetic rehabilitation. The technique described can be used in all cases except situations where esthetic considerations prevail in anterior areas, or in the event of a lack of keratinized gingiva surrounding the implant.

Electrosurgery in restorative dentistry: 1. Theory.

Electrosurgery techniques have been used in dentistry as an aid to soft tissue management for nearly 60 years. However, it was not until the late 1960s that the principles of electrosurgery were understood and improved equipment became available. Part 1 of this two-part series covers the theory behind using this technique. Part 2 will discuss the clinical applications.
