[Use of fluorescence microscopy in the cytochemical evaluation of wound healing after gingivectomy].

The authors investigated in 60 cases the healing process after gingivectomy. The investigation was performed by means of fluorescence microscopy, the presence of nucleic acids (RNA, DNA) and of polysaccharides in the cells being demonstrated. The cytochemical RNA reactions were the most sensitive indicator of wound healing after gingivectomy. Solcoseryl gel accelerated the epithelization of the gingival wound after the surgical intervention, which shortens the period of recuperation.

Melanin repigmentation after gingivectomy: a 5-year clinical and transmission electron microscopic study in humans.

The epithelium-melanin unit is formed by the melanocytes and keratinocytes. There is little information available about the behavior of melanocytes after surgical injury. Five white patients with comparable gingival pigmentation underwent gingivectomy to remove bandlike melanin pigmentations for cosmetic reasons. Biopsy specimens were taken from gingivectomy sites and healing areas 2, 3, 6, 7, 15, 50, and 180 days and 1.5, 3, and 5 years after the procedure. Transmission electron microscopic study revealed melanocytes in the process of migration and undergoing mitosis 6 and 7 days postoperatively. These cells exhibited, in the 15-day specimens, renewal of their dendritic processes and the four different stages of melanosome development. Keratinocytes were devoid of pigmented material until 50 days postoperatively. Clinically, the intensity of the pigmentation varied among the patients. Two reached baseline coloration 1.5 years postsurgery, while three returned to baseline coloration by 3 years postsurgery. Thus, gingival resective procedures, if performed solely for cosmetic reasons, offer no permanent results. (Int J Periodont Rest Dent 1993; 13:85-92.)

The use of chlorhexidine mouthwash compared with a periodontal dressing following the gingivectomy procedure.

The clinical results achieved were compared when a group of 21 patients requiring gingivectomies in comparable bilateral segments received a dressing or a chlorhexidine mouthwash during the first post-operative week. Initial pre-operative conditions were comparable. In each of the two treatments highly significant reductions in pocket depths were achieved; the sizes of the reductions were of clinical significance (greater than 1.5 mm). The observed difference (0.16 mm) between the two treatments in favour of the mouthwash, although significant at the conventional 5% level, was clinically unimportant. More patients preferred the dressing as a post-operative treatment, and the clinical implications of the patients' preferences are discussed.

A comparison between conventional gingivectomy and a non-surgical regime in the treatment of periodontitis.

The treatment of periodontitis by scaling and oral hygiene instruction was compared with the same regime augmented by conventional gingivectomy. The procedures were allocated randomly to contralateral sides of the maxillary arches of 28 patients. Following both regimes there was significant reduction in Plaque Index, Gingival Index, crevicular fluid and depths of pockets. There was slight gain in attachment on the non-surgical sides, and a minor loss of attachment on the surgical sides. Comparing the two regimes, over the second half of the study there was no significant difference in Plaque Index or crevicular fluid; however, on the surgical sides there was significantly greater reduction in Gingival Index and depths of pockets. Residual pockets after either technique were associated with more inflammation than where sulcus depths were less than 2 mm. Retrospective comparisons of the initial depths of pockets with the final gingival status indicated that, when initial depths of pockets had been 3 mm or over, surgical treatment was more effective than non-surgical in reducing the final values of both depths of pockets and inflammation; this finding was statistically significant for some, but not all of the parameters. Treatment of shallow pockets by either technique was more effective than the treatment of deep pockets. Final Plaque Index values of zero were associated with significantly less inflammation and pocketing than where plaque deposits could be detected.

Assessment of tooth mobility using small loads. III. Effect of periodontal treatment including a gingivectomy procedure.

The effect on tooth mobility of periodontal treatment utilizing a gingivectomy procedure was studied during a period of 26 weeks in 25 maxillary anterior teeth of six subjects with moderate to advanced periodontal disease. The gingival conditions were evaluated by gingival fluid measurement and the loss of marginal bone as seen on radiographs. Tooth mobility was measured in a bucco-lingual direction using forces between 20 p and 80 p. The results show a decrease of gingival fluid throughout the study. Tooth mobility was already reduced in the majority of teeth 2 weeks after surgery. An average reduction of tooth mobility amounting to 43.7% (using the corrective formula of Mühlemann 1960) was observed after 4 weeks. No additional reduction took place during the remaining experimental period.

Gingivectomy versus flap surgery: the effect of the treatment of infrabony defects. A clinical and radiographic study.

The aim of this paper was to compare the short-term results of gingivectomy (GV) and modified Widman flap (MWF) surgery in the treatment of infrabony defects. 14 patients with 68 bilateral infrabony defects were selected. At baseline, and 3 and 6 months postoperatively, assessments of oral hygiene, gingival conditions, bleeding on probing, probing pocket depth and attachment level, were recorded. Conventional radiograps were obtained in a way that assured a reproducible projection geometry. In a split-mouth design, one jaw quadrant was randomly treated with GV, while the contralateral with a MWF. The changes of the bone tissue were assessed by means of conventional and subtraction images by 2 observers. The interobserver agreement of the conventional and subtraction technique was studied. The majority of the sites demonstrated a significant improvement in gingival conditions and a reduction in bleeding. For both treatments, probing depths were reduced by an average of 3 mm, while a mean of 1.22-1.35 mm of probing attachment gain was obtained. The GV resulted in slightly more gingival recession (1.90 mm) than the MWF (1.60 mm). The radiographic examination demonstrated gain of bone in 7 defects treated with GV and in 9 defects treated with MWF. This study demonstrated that pockets associated with infrabony defects can be successfully treated by both treatment modalities. Furthermore, bone gain can occur after treatment but not in a predictable manner.

The gingival autograft and gingivectomy.

A rationale and technique for the utilization of the combined procedures of the gingival autograft and the gingivectomy technics for the purpose of pocket elimination and creation of an adequate zone of attached gingiva has been presented. It allows for the predictable and relatively atraumatic treatment of gingival problems in which there has been no deformity of the underlying osseous structures.

The laser gingivectomy. The use of the CO2 laser for the removal of phenytoin hyperplasia.

A new technique for the removal of phenytoin hyperplasia using the carbon dioxide (CO2) surgical laser is presented as well as a review of laser physics and the current uses of the CO2 laser in dentistry. Twelve cases of phenytoin hyperplasia removed surgically by the CO2 laser are presented; hence a laser gingivectomy. Advantages of the procedure include lack of hemorrhage yielding a dry field, noncontact surgery, sterilization of the surgical area, prompt healing, minimal post operative discomfort, and minimal time spent to perform the procedure. At the present time the use of the laser in dentistry is new and limited. In the future the laser may offer an alternative or an advancement to current procedures now used in dentistry.

Smile enhancement via internal gingivectomies.

Periodontal plastic surgical procedures provide a wide range of techniques to improve the esthetics of the mucogingival complex. Often these procedures are prerequisites for successful restorative therapy. This article presents a simple means of enhancing a patient's smile that can be provided by simple internal gingivectomies. The technique can be provided as a stand-alone procedure or in conjunction with restorative care. The surgery is simple and predictable with virtually no postsurgical sequellae.

[Gingivectomies. Flap operations (author's transl)].

Peridontal surgery is only one of a series of treatments for peridontopathies. It is always dependent on buccal hygiene. Gingivectomies and especially flap operations, are one kind of therapeutic solution but not the only one; these are very efficient means to handle the clinical problems. The techniques (listed in the report) must be adapted to each particular circumstance (kind of bone and muco-gingival lesion, etiological factors, stage of disease) and when these techniques are used in their various ways for precise indications they will give the best results.
