The effect of vitamin E on the healing of gingival wounds in rats.

Forty male and female albino rats received a standardized gingival wound (gingivectomy) between the mandibular incisor teeth. One half of the animals received 60 I.U. of d-alpha-tocopheryl acetate daily, administered orally by pipette. An additional control group of 20 animals was not wounded and half of these animals received 60 I.U. of d-alpha-tocopheryl daily. Four animals in each of the two gingivectomy groups (Groups 1, 2) were sacrificed at periods of 1, 2, 4, 7 and 14 days following gingivectomy. Two animals in each of two control unwounded groups (Groups 3, 4) were sacrificed at similar times. Gingival healing was studied grossly and histologically. The animals receiving the vitamin E supplements healed more rapidly, with almost complete restoration of gingiva by 7 days. Complete healing was seen in both control and experimental groups by 14 days. Vitamin E was shown to accelerate gingival wound healing in experimental animals.

Anesthetic management of a patient with Sturge-Weber syndrome undergoing oral surgery.

This case involves a possible complication of excessive bleeding or rupture of hemangiomas. Problems and anesthetic management of the patient are discussed. A 35-year-old man with Sturge-Weber syndrome was to undergo teeth extraction and gingivectomy. Hemangiomas covered his face and the inside of the oral cavity. We used intravenous conscious sedation with propofol and N2O-O2 to reduce the patient's emotional stress. It was previously determined that stress caused marked expansion of this patient's hemangiomas. Periodontal ligament injection was chosen as the local anesthesia technique. Teeth were extracted without excessive bleeding or rupture of hemangiomas, but the planned gingivectomies were cancelled. Deep sedation requiring airway manipulation should be avoided because there are possible difficulties in airway maintenance. Because this was an outpatient procedure, propofol was selected as the sedative agent primarily because of its rapid onset and equally rapid recovery. Periodontal ligament injection with 2% lidocaine containing 1: 80,000 epinephrine was chosen for local anesthesia. Gingivectomy was cancelled because hemostasis was challenging. As part of preoperative preparation, equipment for prompt intubation was available in case of rupture of the hemangiomas. The typically seen elevation of blood pressure was suppressed under propofol sedation so that expansion of the hemangiomas and significant intraoperative bleeding was prevented. Periodontal ligament injection as a local anesthetic also prevented bleeding from the injection site.

Comparison of 1% and 2% lidocaine hydrochloride used as single local anesthetic: effect on postoperative pain course after oral soft tissue surgery.

It is known that some local anesthetics may cause pain when the initial local anesthetic effect disappears. The aim of this trial was to compare the postoperative pain intensities after infiltration of plain lidocaine 1% and 2% used in gingivectomies. The trial was done as a controlled, randomized, double-blind, parallel group study involving 117 patients with mean age 48 years (range 29-71 years) allocated to two treatment groups. There was no statistically significant difference between the mean postoperative pain courses of lidocaine 1% and 2% after gingivectomies during an 11-h observation period. A numerical difference was seen from 7 to 11 h in favor of lidocaine 1%. There were more patients experiencing no pain, but more patients reporting higher pain scores in the lidocaine 2% group than in the lidocaine 1% group. These differences were not statistically significant. It can be concluded that there is apparently no difference between lidocaine 1% and 2% with respect to postoperative pain experience when using gingivectomy as a pain model.

Periodontal laser surgery.

A gingivectomy performed with a laser is a short, easy procedure that produces an immediately dramatic effect. Compared to a scalpel gingivectomy, there is excellent hemostasis, which improves visualization, requires less need for periodontal packing, and results in minimal postoperative discomfort. Tissue rebound also is minimal. Use of lasers requires specific training. The only approved function in periodontics at this time according to the American Academy of Periodontology is soft tissue surgery. Some periodontal applications include frenectomy, soft tissue crown lengthening, distal wedge procedures, soft tissue tuberosity reductions, gingivectomy, gingivoplasty, stage II of implants, operculectomies, biopsies, coagulation of graft donor sites, hemorrhage disorder patients, and stripping procedures for various leukoplakias.

Idiopathic gingival hyperplasia and orthodontic treatment: a case report.

There are many reasons for gingival hyperplasia. Mostly, proper oral hygiene is sufficient to achieve normal healthy gingiva. In some situations, however, gingival hyperplasia is drug-induced or can be a manifestation of a genetic disorder. In the latter, it may exist as an isolated abnormality or as part of a syndrome. If orthodontic treatment is needed in patients with gingival hyperplasia, both orthodontic and periodontal aspects need to be considered. Extreme hereditary gingival fibromatosis was periodontally treated, by removal of all gingival excess using flaps and gingivectomies. After a follow-up period, the orthodontic treatment started with fixed appliances. Monthly periodontal check-ups (scaling and polishing) were scheduled to control the gingival inflammation. After the orthodontic treatment, permanent retention was applied, once more followed by a complete gingivectomy in both maxilla and mandible. One of the most important keys to successful treatment of hyperplasia patients is the cooperation between the periodontist and the orthodontist.

Effect of chlorhexidine on gingival wound healing in the dog. A histometric study.

Wound healing after gingivectomy was studied in five 1-year-old dogs (Beagles). During a preparatory period of 4 months, the teeth of the dogs were brushed twice a day using a toothbrush and dentifrice. At the end of this period, all gingival units appeared healthy. All mechanical tooth cleaning procedures were then terminated. Following a period a 2 weeks without oral hygiene, six gingival units, taken bilaterally from the maxillary first molar and posterior premolar areas, were subjected to standardized gingivectomies. Subsequently, the biopsied areas of the left half of the jaws were treated twice a day with a 0.2% aqueous solution of chlorhexidine digluconate for 42 days, while corresponding areas of the right jaws were given saline treatment. Tissue specimens were obtained after healing periods of 42, 28, 14, 7, 4 and 2 days. They were then immediately placed in a Karnovsky fixative, and afterwards decalcified in EDTA. The rate of tissue regeneration and degree of inflammatory cell infiltration were evaluated with histometric methods. It was found that while gingival wounds treated with saline regenerated with extensive inflammatory reactions, corresponding chlorhexidine-treated wounds healed with only minor signs of inflammation.

Vascular morphology in noninflamed healed gingiva of dogs.

The objective of this study was to determine if the regular vascular network previously reported as occurring in noninflamed marginal gingiva would become re-established following plaque control and treatment of gingiva by gingivectomy and scaling. Gingivectomies were performed on dogs with and without pre-experimental gingivitis in order to obtain gingival specimens healed for 4, 8 and 12 weeks. Plaque was controlled using toothbrushing and topical applications of 0.2% chlorhexidine gluconate. After 12 weeks, the animals were perfused via the carotid arteries with glutaraldehyde and Microfil latex compound. Specimens were processed for either routine histology or examination of vascular morphology in methyl salicylate cleared tissues. The absence of inflammation in healed gingiva was evaluated clinically, using the Gingival and Plaque Indices, and histologically. Results showed that in healed clinically and histologically noninflamed gingiva, the vascular morphology was established as a series of looped vessels which could readily be distinguished from the regular network of vessels described by Hock (1975) in marginal gingiva that had neither been inflamed nor resected.

Hemangioendothelioma of the gingiva. Histopathologic and therapeutic considerations.

The hemangioendothelioma is a benign neoplasm, rarely observed in the mouth. In the literature, reports on the treatment and on the therapeutic results are lacking. This type of gingival neoplasm was observed in a young adult male. It was located in the attached gingiva in the upper and in the lower jaw, covering almost the entire coronal part of the anterior teeth. An exhaustive internal and neurological examination revealed no associated general disease. The gingival biopsies displayed the typical characteristics of a hemangioendothelioma: proliferation of the blood vessels, with a reduced lumen surrounded by swollen endothelial cells. The treatment consisted of a meticulous mechanical plaque control, chlorhexidine rinses, gingivectomy procedures and a monthly professional prophylaxis. 3 years after the periodontal treatment, the gingival structures remained clinically healthy. In the biopsies, only a small amount of inflammatory cells could be detected. This report shows a case of benign gingival neoplasms of unknown etiology in which meticulous plaque control, combined with extensive gingivectomies and repeated professional prophylaxis may have prevented or, at least, retarded the recurrence of the lesion.

Effect of non-eugenol- and eugenol-containing periodontal dressings on the incidence and severity of pain after periodontal soft tissue surgery.

This study examines the incidence and severity of postoperative pain after gingivectomy using one non-eugenol-containing periodontal dressing, Coe-pak (n = 76) and 2 eugenol-containing periodontal dressings, Wondrpak (n = 64) and Nobetec (n = 86). All patients were subjected to gingivectomy using 1 type of local anaesthesia (lidocaine + adrenalin) only and covering the surgical areas with either of the 3 different dressings in a randomized study. Postoperative pain was assessed on 100 mm visual analogue scales over 5 days starting immediately after surgery. No pain was reported by 22.0% of the patients after Coe-pak, 23.4% after Wondrpak and 30.2% after Nobetec. 13.2% of the patients took analgesics after Coe-pak treatment, 3.1% after Wondrpak and 1.2% after Nobetec. Mean pain score after Coe-pak was higher (P less than 0.05) than after Nobetec 2 h after operation until the morning on the 3rd postoperative day. Mean pain score after Coe-pak was higher (P less than 0.05) than after Wondrpak 3 h to 9 h after operation. No statistically significant difference was found between Wondrpak and Nobetec regarding mean pain score.

A sheep cadaver model for demonstration and training periodontal surgical methods.

There is lack of data on the suitability of animal cadaver models for teaching purposes in dentistry. Here, we describe a model suitable for training for several periodontal surgical methods. Mandibles of freshly slaughtered Australian adult sheep and lambs were examined. Periodontal probing depths (PPDs) were measured at six sites of every tooth present. The following surgical techniques were critically analyzed: access flap with interrupted, continuous sutures; apically repositioned flap with periosteal sutures; coronally advanced flap with sling suture; gingivectomy; and distal wedge procedure. Probing depths were highest in the buccal furcation area of 1st and 2nd molars, where deep intrabony lesions were present in certain samples from adult sheep. Another area of increased probing depth was lingual to canines and incisors. Here, a pronounced lower dental pad of fibrous tissue was present. In this area, gingivectomy could always be accomplished. Fibrous tissue was also found distal to the most posterior molar, where the distal wedge procedure could be exercised. Access flaps and apically repositioned flaps could be performed particularly at premolars. Here, interrupted or continuous sutures were possible. Because of tight interdental contact areas, needle insertion was difficult at molars. After periosteal dissection, labial flaps at anterior teeth could easily be advanced coronally and sutured with sling sutures. Because of the teeth's dimensions and tight contact areas, simulation of more advanced techniques such as papilla preservation flaps was not possible. The sheep mandible seems to be a feasible training model for the demonstration and exercise of various periodontal surgical techniques for the treatment of periodontitis.

Effect of periodontal treatment on gingival overgrowth among cyclosporine A-treated renal transplant recipients.

No data exist on any association between combined cyclosporine A (Cy A) and dihydropyridine (DHP) medication and the effect of periodontal treatment on the occurrence of gingival overgrowth (GO) among renal transplant recipients. Clinical data on 27 renal transplant recipients treated with Cy A are presented here, including determinations of serum creatinine, whole blood Cy A concentration, existence of DHP treatment, and periodontal status. GO was classified into four categories according to the clinical changes: score 0 = no GO; score 1 = mild GO; score 2 = moderate GO; and score 3 = severe GO. All participants received hygiene phase periodontal treatment and gingivectomies were performed on 10 who originally had score 2 or 3 GO and pocketing. Fourteen (14) of the recipients had no overgrown gingiva or less than at the initial examination, and none of them had GO score 2 or 3 at the time of re-examination (group A). Thirteen (13) participants had more overgrown gingiva than initially or developed score 2 GO after gingivectomies (group B). Group B included significantly more DHP-medicated recipients than group A (6/13 and 1/14 respectively; P < 0.03). The concomitant administration of Cy A and DHP resulted in a significantly increased percentage of score 2 overgrown gingival units as compared with Cy A alone (P < 0.03). It is concluded that combined treatment with Cy A and DHP is a significant risk factor for progression or recurrence of GO after periodontal treatment among susceptible patients.

Epidermolysis bullosa acquisita: clinical manifestations, microscopic findings, and surgical periodontal therapy. A case report.

BACKGROUND: Epidermolysis bullosa acquisita (EBA) is an uncommon, acquired, chronic subepidermal bullous disease. This report describes a case of EBA with gingival involvement. A 43-year-old woman with EBA was referred to our clinic for periodontal therapy because of gingival tenderness and bleeding. She has been on cyclosporin A therapy for the last 2 years. METHODS: Clinical findings were analyzed. Anterior gingivectomy operations were performed in 2 stages. The samples obtained during the surgery were examined using histopathologic, immunohistologic, and electronmicroscopic methods. Long-term effects of the surgical periodontal treatment on gingiva were evaluated both clinically and microscopically. RESULTS: The dentition displayed minimal enamel hypoplasia. Decayed, missing, and filled surfaces score was found to be elevated. Periodontal examination showed generalized diffuse gingival inflammation and gingival enlargement localized mainly to the anterior region. Nikolsky's sign was positive. However, wound healing was uneventful after the operations. Microscopic findings were similar to those obtained from the skin. Twenty-one months after the operations, Nikolsky's sign was negative and no remarkable gingival inflammation was noted. Microscopic examination revealed that the blisters were fewer in number and smaller in size. CONCLUSIONS: These results indicate that gingival tissues may also be involved in EBA. Uneventful wound healing after periodontal surgery in this case suggests that periodontal surgery can be performed in patients with EBA. Moreover, both our clinical and histopathologic findings imply that gingivectomy proves useful in maintaining gingival integrity in these patients. Our data may also suggest that the patients with EBA are highly likely to develop dental caries.

Hereditary gingival fibromatosis associated with generalized aggressive periodontitis: a case report.

BACKGROUND: Hereditary gingival fibromatosis is a rare, genetically inherited overgrowth condition that is clinically characterized by a benign fibrous enlargement of maxillary and mandibular keratinized gingiva. A syndromic association between gingival fibromatosis and a wide variety of other genetically inherited disorders has been described. However, its coexistence with aggressive periodontitis has not been reported. METHODS: A 24-year-old African-American female, patient (proband X, [Px]) reported with a chief complaint of tooth mobility and gingival enlargement. Clinical examination revealed moderate to severe gingival overgrowth on both mandible and maxilla. Generalized attachment loss and mobility of the teeth were observed. Radiographic evaluation demonstrated severe alveolar bone loss. The patient was diagnosed with gingival fibromatosis and aggressive periodontitis based on the clinical and radiographic findings. Her brother (Bx) and her mother (Mx) were evaluated and diagnosed with gingival fibromatosis suggesting that this is a dominant trait in the family and gingival fibromatosis might be of hereditary origin. In addition, the brother also exhibited localized aggressive periodontitis. Medical history revealed no other systemic or local contributory factors associated with the oral findings in any of the subjects. RESULTS: Surgical therapy included internal bevel gingivectomy combined with open flap debridement procedures for Px and Bx. Only internal bevel gingivectomy was performed for Mx since there was mild bone resorption and no intrabony defects. At the time of surgery, gingival biopsies were obtained and fixed in 4% paraformaldehyde. Multiple serial sections were stained with hematoxylin and eosin. Microscopic evaluation of the gingival specimens revealed large parallel collagen bundles associated with scarce fibroblasts in the connective tissue. The collagen bundles reached into the subepithelial connective tissue where elongated rete-pegs were also observed. Following the completion of the treatment, no signs of recurrence or bone resorption were observed over 2-year follow-up. CONCLUSIONS: This is the first report of hereditary gingival fibromatosis associated with aggressive periodontitis. Combined treatment comprising removal of fibrotic gingival tissue and traditional flap surgery for the elimination of intrabony defects represents a unique treatment approach in periodontal therapy. Two-year follow-up revealed that both the gingival overgrowth and the destructive lesions were successfully treated.

The effect of chlorhexidine supplementation in a periodontal dressing.

Most commercial periodontal dressings claiming antibacterial activity lose this activity shortly after application. Chlorhexidine (CH) is an antibacterial agent with long-term activity in the oral cavity owing to its substantiveness and slow-release properties. In a double-blind split-mouth-designed clinical trial the effect of incorporating CH acetate in periodontal dressing was tested on wound healing after gingivectomy. Eleven patients, each needing at least two gingivectomies, constituted the test panel. Wound healing, as assessed by bleeding tendency after removal of dressing 7 days postoperatively was significantly delayed when control dressings were applied as compared with test dressings. Variables with regard to patient comfort also yielded results in favor of the test pack. Incorporation of antibacterial agents with high retention and slow release properties in the mouth in surgical dressings seems advantageous.

[Lasers in dentistry. 5. The use of lasers in periodontology].

This literature review shows that the Nd:YAG laser and the Er:YAG laser can be beneficially used in periodontology for subgingival curettage and gingivectomy. Studies demonstrated that subgingival laser treatment can result in significant reduction of the initial levels of periodontal pathogens. It is beneficial to perform laser curettage under water irrigation prior to scaling in order to destroy of the structure of the calculus and its attachment to the root surface. During laser curettage sufficient haemostasis is obtained, which improves detection of subgingival calculus. Nd:YAG laser gingivectomy results in similar improvement of deep periodontal pocket as conventional flap surgery, with the advantages such as minimal bleeding and post-operative pain, no swelling, and neither sutures nor post-surgical dressing are needed. Both non-surgical and surgical laser treatments are often performed without local anaesthesia, making full-mouth treatment in one session possible. Treatments are well accepted by the patients and require about 50% less time than the conventional therapies. Laser-de-epithelialization for periodontal regeneration has been experimentally attempted, but more controlled studies are needed to establish its usefulness in the clinic. Laser treatment of peri-implantitis is not recommended.

[Organ transplant patients' complex periodontal treatment].

The number of organ transplant patients has increased in recent years. The Cyclosporin-A (CsA) has been used at least for 20 years to control graft rejections. As many organ transplant patients also take Ca channel blocking medication this might potentiate the CsA associated gingival hyperplasia. The outcome of the comprehensive periodontal treatment was evaluated in 14 kidney and liver transplant patients. If gingival overgrowth showed no marked reduction after thorough professional supra and subgingival plaque control either gingivectomy or flap surgery were indicated. The average age of the organ transplant patients was 38 years. 10 was man and 4 female. The daily dose of CsA ranged between 150-200 mg, and each patient took also Ca channel blocking drugs, 5-20 mg/day. S/RP alone was successful in two cases. Gingivectomy was performed in 10 cases and flap operation was indicated in two cases. Among patients with high compliance and excellent individual oral hygiene no recurrence occurred, while two patients with very low level of oral hygiene showed immediate gingival overgrowth after surgery. It is supposed that dental plaque is an important contributing factor in the development of drug induced gingival overgrowth and meticulous plaque control should be one of the most important treatment modalities in controlling drug-induced gingival changes.

[Pre and postoperative determination of the gingival sulcus fluid for the control of the healing process after periodontal surgery].

To objectify the healing process after gingivectomy and flap operation, the gingival sulcus liquid was determined in 20 patients before and after the operation. It was drawn off in the labial part of the sulcus of anterior teeth by means of microcapillaries and then measured. At the same time, the gingival index (M-index) was checked and the depth, of the pocket was measured. Four weeks after the operation, a clear reduction in the amount of the gingival liquid, the index and the depth of the pocket was observed. The group of probands on which flap operations were performed, had twice as much sulcus liquid than those undergoing gingivectomy, and consequently the amount of exudate decreased considerably more within the first three weeks. After the third postoperative week, the average values converged and after the fourth week they were almost identical. The M-index changed accordingly, the average pocket depth was between 1 and 1.5 mm after four weeks.

Lectin binding patterns in regenerated rat junctional epithelium.

Junctional epithelium (JE) originates from reduced enamel epithelium and is replaced by cells from oral gingival epithelium (OGE) shortly after tooth eruption. Although derived from OGE, cells of JE exhibit both morphologic and functional differences from precursor tissue. We sought to elucidate these differences by investigating histochemical localization of cell surface glycoconjugates in regenerated epithelial cells following gingivectomy in the rat. Distribution and reaction patterns of lectins (Ulex europaeus agglutinin-I, peanut agglutinin, soybean agglutinin, and wheat germ agglutinin) were determined using both light and electron microscopy. We found that although regenerated JE derived from OGE following gingivectomy, its morphologic features as well as histochemical lectin patterns underwent transition to those of non-treated JE. These findings indicate that freshly regenerated JE and primary JE are morphologically and histochemically similar.
