The remodeling of human gingival tissues following gingivectomy.

A total of 30 facial gingivectomies were carried out for reduction of suprabony pockets (mean +/- S.D. preoperative pocket depth 2.8 mm +/- 0.3 mm). Remodeling of the gingival margin was monitored by clinical measurements. The following techniques were utilized: A polyvinyl stent was constructed for each surgical quadrant. This stent covered the occlusal margins of the involved teeth and contained the fixed point of reference. Preoperatively, the following measurements were taken: the distance from the fixed point to (a) the height of the free gingival margin, and (b) the base of the clinical pocket. For control purposes similar measurements were taken at the facial surface of an adjacent tooth. A standard gingivectomy to the base of the clinical pocket was then performed and a periodontal dressing was applied for 1 week. Utilizing the stent (fixed point of reference), measurements were taken of the healing margin and control sites inn the same manner as preoperatively; 1,4,8 and 12 weeks after surgery. Our findings indicate that 12 weeks after gingivectomy, the newly formed free gingival margin was located coronally to the line of incision in all cases. The mean pocket depth at 12 weeks after surgery was 0.7 mm +/- 0.2 mm. However, the mean gain in coronal marginal height was 1.2 mm +/- 0.3 mm. Thus, a clinical coronal pocket closure of about 0.5 mm seemed to have taken place at the soft tissue-tooth interface. Measurements at the nonoperated control site showed no significant variations in crevicular depth during the experimental period. We therefore conclude that the excisional reduction of a crevice to 0 mm depth was altered by gingival remodeling during the healing phase. In our experience, this remodeling took place within 3 months after surgery and clinically appeared as a limited coronal pocket closure and gain of marginal height.

Gingival fluid flow after gingivectomy related to mechanical or chemical plaque control.

The effects of mechanical tooth cleaning and 0.2% chlorhexidine mouthrinses on healing after gingivectomy were compared in 8 patients by means of a "split mouth" technique. The experiment began after periodontal pack removal on day 7. Gingival fluid was sampled immediately before and on days 14, 21, 28, 35 after gingivectomy. The results showed that mechanical and chemical plaque control were equally effective in promoting healing after gingivectomy as evaluated by gingival fluid measurements.

The present status of the gingivectomy procedure.

The use of the conventional gingivectomy procedure is indicated to achieve optimum gingival contour and to eliminate supra-alveolar pockets where these do not extend beyond the muco-gingival junction. The instrument of choice for the procedure is a gingivectomy knife. Where a blood-free field is required, electrosurgery may be used provided the instrument is not brought into contact with bone. The maintenance of good oral hygiene is essential.

The effect of chlorhexidine mouthrinse on healing after gingivectomy.

The purpose of this investigation was to evaluate the effect of 0.2% chlorhexidine gluconate mouthrinse following gingivectomy on plague under the dressing and on healing. Twenty-eight patients with indications for gingivectomy were selected. Coe-Pak was used as surgical dressing. In addition to unsual home care, the patients rinsed twice daily with chlorhexidine or placebo for 21 d after surgery. The study followed a cross-over double-blind design. Gingival exudate was assessed and Pl I and G I were registered at 7, 14, and 21 d postsurgically. The study indicated that chlorhexidine did not influence the amount of plaque under the dressing, and it was uncertain whether chlorhexidine had any effect on the healing process when the surgical area was covered by Coe-Pak. However, (1) after the surgical dressing was removed, the chlorhexidine maintained plaque scores at the same low level as under the dressing, (2) healing was was promoted when chlorhexidine was used, and (3) the presence of a dressing in one side of the mouth did not prevent the patient from maintaining good oral hygiene.

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.

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.

[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.
