Comparative clinical study of a bioabsorbable membrane and subepithelial connective tissue graft in the treatment of human gingival recession.

BACKGROUND: Connective tissue grafts and guided tissue regeneration (GTR) are the most current procedures in the treatment of gingival recession, but very few clinical comparative studies have been conducted. METHODS: The purpose of this study was to compare 2 types of treatment of gingival recession in the same patients. Fourteen pairs of Miller Class I defects were selected in 14 patients. In each pair, one recession was randomly assigned for treatment by GTR using a bioabsorbable membrane, and the other treated by subepithelial connective tissue graft (CTG). Height of recession (HR), clinical attachment level (CAL), probing sulcus depth (PSD), height of keratinized tissue (HKT), and distance from the cemento-enamel junction to the mucogingival junction (CEJ-MGJ) were recorded before surgery and 6 months postoperatively. RESULTS: The initial width and height of recession were, respectively, 3.73 mm (SD 0.56) and 3.85 mm (SD 1.15) for the CTG group, and 4.04 mm (SD 0.92) and 4.28 mm (SD 1.20) for the GTR group. The differences were not significant. CAL changes were not different. Both in the CTG group and in the GTR group, mean HR reduction was 2.89 mm (SD 1.18), representing a mean root coverage of 76% and 70.2%, respectively. The difference was not significant. HKT mean gain was significantly greater (P = 0.0001) with CTG (2.03 mm, SD 0.92) than with GTR (0.42 mm, SD 0.91). The GTR technique displaced the mucogingival junction significantly (P = 0.007) more coronally (2.35 mm, SD 1.44) than the CTG technique (0.78 mm, SD 1.23). CONCLUSIONS: Within the limits of this study, no difference could be found between subepithelial connective tissue graft and GTR with a bioabsorbable membrane with regard to root coverage, but the GTR technique did not increase the height of keratinized tissue and displaced the mucogingival junction more coronally at 6 months.

Improvement of multiple facial gingival recession by non-surgical and supportive periodontal therapy: a case report.

We report a case of multiple facial gingival recession which was improved by non-surgical and supportive periodontal therapy. The patient, a 28-year-old Japanese woman, presented for treatment of multiple facial gingival recession ranging from 1 to 4 mm on teeth 5 through 12 and 19 through 30. Periodontal plastic surgery to cover the exposed multiple root surfaces was suggested. However, because of emotional problems, the patient did not wish to undergo the procedures and instead accepted non-surgical periodontal therapy including oral hygiene instruction, scaling, and root planing. The exposed root sites were monitored at periodic maintenance visits, and gradual improvement through a coronal increase of the gingival margin was noted. The possible etiologic factors and healing process associated with this case are discussed.

Viral etiology of gingival recession. A case report.

Herpes simplex virus-type I (HSV-1) is responsible for both primary and recurrent infections of the oral mucosa. The aim of this case report is to show how HSV-1 may cause periodontal damage such as gingival recession. A 26-year-old male patient presented in a private office for the treatment of gingival recessions. He reported that the recessions had appeared suddenly with marginal inflammation of the gingiva and vesicle formation; within a few hours, the gingival tissue had been completely destroyed. The lesions were accompanied by pain, fever, and regional lymphadenopathy. Two weeks later, the patient returned complaining of a recurrence accompanied by pain and lymphadenopathy. The following day, the patient's condition had worsened and the depth of the recession had increased. A biopsy was taken for histological examination. A free epithelial-connective tissue graft was performed. Histological and direct immunofluorescence examinations confirmed the herpetic origin of the lesion. Eight months after surgery, a new herpetic lesion was detected in correspondence to the gingival margin of the first lower right premolar; therefore, acyclovir was prescribed. After 1 week, the antiviral therapy was completely successful; the gingival lesion disappeared, and no recession of the soft tissue margin was observed. Based on these clinical features, diagnosis of gingival recession induced by HSV-1 must be carried out at an early stage to establish a successful therapy.

Combined guided tissue regeneration, root conditioning, and fibrin-fibronectin system application in the treatment of gingival recession. A 15-case report.

This paper describes a surgical technique to achieve root coverage in deep, wide gingival recessions using a root isolation procedure with ePTFE membrane, combined with tetracycline conditioning of the root surface and fibrin-fibronectin sealing system application. The technique was used on 15 patients with isolated mucogingival defects 4 to 6 mm deep. A large trapezium-shaped flap was raised 3 to 4 mm apical to the margin of the bone dehiscence. The root surface was thoroughly scaled by hand and rotating instruments. Tetracycline HCl solution (100 mg/ml) was topically applied for 4 minutes. Expanded polytetrafluoroethylene (ePTFE) membrane was adapted at least 1 mm coronal to the CEJ and retained in position by sling sutures. A film of fibrin-fibronectin sealing system was injected between the membrane and the root surface. The flap was sutured coronally and the membrane removed 6 weeks later. The patients were reevaluated 6 months after the reentry procedure. The mean recession depth decreased from 4.7 mm initially to 1.1 mm at the final postoperative appointment. This represents a mean root coverage of 77.4%. Mean probing depth reduction was 0.9 mm and the mean width of keratinized tissue increased from 1.8 mm preoperatively to 2.9 mm 6 months after surgery. These findings show that the treatment of buccal gingival recession using guided tissue regeneration procedure plus tetracycline root demineralization and fibrin-fibronectin glue application results in a consistent and predictable improvement of mucogingival defects.

A single-step GTR treatment for gingival recession with a bioresorbable membrane: a case report.

Creating a single-step surgical treatment for coverage of gingival recession has long been the objective in the development of guided tissue regeneration. A single-step procedure would avoid the trauma of a second surgery and eliminate the limitations associated with soft tissue grafts and nonresorbable barriers. It would also ensure the predictable integration of the bioresorbable membrane in the periodontal tissue and the clinical repair of gingival recession. The learning objective of this article is to present the clinical application of a bioresorbable matrix along with the indications and advantages of the procedure. Three case reports are used to illustrate the clinical technique.

A possible influence of gingival dimensions on attachment loss and gingival recession following placement of artificial crowns.

The aim of the present study was to determine the influence of gingival dimensions on the development of gingival recession following placement of artificial crowns. The study population consisted of 11 periodontally healthy patients in whom 44 maxillary anterior teeth and/or premolars had to be crowned. A total of 36 teeth (82%) had, after crown placement, a mean intracrevicular crown margin of 0.57 +/- 0.47 mm. Thirty-nine teeth without restorations served as controls. Immediately after incorporation, as well as after 3, 6, 9, and 12 months, periodontal examinations were carried out. Gingival thickness was determined sonometrically and averaged 1.25 +/- 0.40 mm. Mean periodontal probing depth was 1.80 +/- 0.54 mm. Twelve months later, crowned teeth had experienced a mean attachment loss of 0.17 +/- 0.99 mm as compared to an attachment gain of 0.18 +/- 0.46 mm at control teeth. At test teeth, the gingival margin had receded a mean of 0.43 +/- 0.74 mm. In multivariate analyses considering the correlated structure of the data employing generalized estimating equation methods, crown placement was identified as a major factor for attachment loss and development of gingival recession. In addition, a shallow probing depth and narrow band of gingiva negatively influenced the level of periodontal attachment. The present results point to the importance of a more detailed periodontal diagnosis of the dentogingival region before placement of artificial crowns.

Comparison of 2 techniques of subepithelial connective tissue graft in the treatment of gingival recessions.

BACKGROUND: The clinical outcome of connective tissue grafts in the treatment of gingival recessions has been documented in numerous studies. However, no attempt has been made to correlate the postoperative mucogingival changes with the surgical parameters. The present retrospective clinical study was undertaken to 1) evaluate root coverage and mucogingival changes 1 to 1.5 years following treatment of Miller's Class I and II recession defects using 2 variants of the subepithelial connective tissue graft (SCTG) procedure, and 2) assess the effect of the surgical parameters on the postoperative gingival width. METHODS: Thirty-one recessions in 10 patients treated with the envelope technique (E) and 31 recessions in 11 patients treated with coronally positioned flap combined with connective tissue graft (CP) were retrospectively analyzed to evaluate: 1) percentage of root coverage obtained with the 2 procedures and variations in width of keratinized tissue (KT) 1 to 1.5 years postsurgery, and 2) the effect of the surgical parameters on the postoperative gingival width. RESULTS: Results showed a mean root coverage percentage of 89.6 +/- 15% for the E group and 94.7 +/- 11.4% for the CP group; the difference between groups was statistically insignificant (P = 0.1388). Mean KT increased significantly from 1.4 +/- 1.1 mm presurgery to 4.5 +/- 1.1 mm postsurgery for the E group while a minor increase in KT was observed in the CP group (2 +/- 1.5 mm presurgery versus 2.7 +/- 1.6 mm postsurgery). For both treatment groups, the mean postsurgical width of keratinized tissue (POSTKT) was found to be mathematically correlated with the mean presurgical width of keratinized tissue (PREKT) and the corono-apical height of the graft that remained exposed (GE) coronal to the flap margin in the recipient site. CONCLUSIONS: Treatment of human gingival recession defects by the 2 variants of SCTG resulted in significant recession reduction. When SCTG is grafted beneath alveolar mucosa using the combined technique (CP), transformation of the mucosa into keratinized tissue does not seem to occur, at least within 1 to 1.5 years postsurgery. The treatment outcome in terms of keratinized tissue width seems to be correlated with the presurgical gingival dimensions and the height of the graft that remains exposed at the end of the surgical procedure.

A 3-year longitudinal evaluation of subpedicle free connective tissue graft for gingival recession coverage.

BACKGROUND: The purpose of this study was to longitudinally evaluate, over a 3-year period, the reduction of gingival recession through use of a subepithelial free connective tissue graft placed under a coronally advanced partial-thickness pedicle flap. METHODS: Twenty-one buccal recession defects (mean 3.67 mm; range 3 to 4.5 mm; Miller Class I, II, and III) in 15 patients were treated using this technique. Amount of gingival recession (GR), clinical attachment loss (CAL), and width of keratinized gingiva (WKG) were followed for 3 years after surgery. The measurements were performed at presurgery, and 1, 3, 6, 12, 18, 24, and 36 months postsurgery. RESULTS: GR decreased from 3.67 +/- 0.58 mm at baseline to 0.33 +/- 0.43 mm at 36 months, representing a reduction of 3.33 mm, corresponding to 91.28% mean root coverage. CAL was significantly decreased at 36 months from 5.26 +/- 0.77 mm to 2.14 +/- 0.57 mm. At 36 months, 3.12 mm of attachment gain was obtained. WKG significantly increased after 36 months (1.95 mm). GR, CAL, and WKG had the most positive outcomes at 12 months and were maintained at stable levels throughout the 36-month observation period. CONCLUSIONS: These results indicate that the connective tissue graft with a partial thickness coronal advancement pedicle is a predictable method for root coverage and, provided that optimal maintenance care is provided, the clinical outcomes gained by this technique can be well maintained.

Treatment of gingival recessions by combined periodontal regenerative technique, guided tissue regeneration, and subpedicle connective tissue graft. A comparative clinical study.

BACKGROUND: Many surgical techniques have been shown to be effective in correcting gingival recessions by covering the exposed root with soft tissue; however, the thickness of the gingival tissue over the root surface probably plays an important role in preventing the recurrence of tissue recession. The aim of the present study was to compare the results of a mucogingival bilaminar technique (BT), guided tissue regeneration (GTR), and a combined periodontal regenerative technique (CPRT) in achieving root coverage and increasing the gingival thickness 1 year after surgical treatment. METHODS: In 45 systemically healthy, non-smoking patients aged 33.6 +/- 4.3 years with no periodontal pockets >4 mm, a Miller's Class I or II gingival recession was treated for root coverage: 15 patients underwent BT (connective tissue with partial-thickness double pedicle graft), 15 GTR by a bioabsorbable membrane, and 15 CPRT by a collagen membrane and collagen-incorporated hydroxyapatite. Before and 1 year after surgical treatments, the following clinical parameters were recorded: gingival recession (GR), probing depth (PD), clinical attachment level (CAL), keratinized tissue width (KT), and gingival thickness (GT); the percentage of root coverage was also calculated and the data were statistically analyzed. RESULTS: All 3 techniques yielded significant improvements in terms of GR decrease, CAL and KT gain, and GT increase compared to baseline values. Mean root coverage was 90.0%, 81.01%, and 87.12% in BT, GTR, and CPRT groups, respectively. Complete root coverage was observed in 60%, 40%, and 53.3% of subjects from the BT, GTR, and CPRT groups, respectively. No significant differences were observed among the 3 techniques in GR or CAL improvements; however, BT produced a significantly (P<0.01) greater increase of KT, and BT and CPRT groups showed a significantly (P<0.01) greater increase of GT compared to the GTR group. CONCLUSIONS: BT, GTR, and CPRT successfully treated gingival recession defects, obtaining comparable percentages of root coverage, but BT and CPRT created a thick gingival tissue significantly greater than that achieved with GTR.

Treatment of multiple adjacent gingival recessions with the tunnel subepithelial connective tissue graft: a clinical report.

This article describes a surgical periodontal plastic procedure for the coverage of multiple adjacent gingival recessions. This surgical technique is based on the construction of a tunnel under the gingival tissue by means of a sulcular incision beyond the mucogingival line without raising the papillae. A large connective tissue graft obtained from the palatal mucosa is introduced through this tunnel, covering the adjacent gingival recessions. A suturing technique to allow this graft to slip through the tunnel under the gingival tissues and to secure and stabilize the graft covering the recessions is described. Twelve-month postoperative results are presented from 21 teeth that were treated with this technique: 100% root coverage was achieved in 66.7% of the recessions treated, with a mean root surface coverage of 91.6%. This study suggests that the use of this surgical procedure allows the treatment of multiple adjacent recessions in a single procedure with adequate early healing and highly predictable root coverage results.

Subpedicle acellular dermal matrix graft and autogenous connective tissue graft in the treatment of gingival recessions: a comparative 1-year clinical study.

BACKGROUND: Many surgical techniques have been proposed for the correction of dental root exposition. Among these, bilaminar techniques (BTs) have been reported as offering the best results in terms of root coverage (RC). However, BTs require a second surgical site to harvest the graft, with discomfort for the patient. The use of an acellular dermal matrix (ADM) avoids the need for a donor site. The aim of this study was to compare the clinical results of 2 BTs by autogenous connective tissue (CT) or ADM. METHODS: In 30 systemically healthy, non-smoking patients aged 34.5 +/- 5.2 years, who showed no periodontal pockets >4 mm after a hygienic phase, a Miller's class I or II gingival recession was treated for root coverage. All patients underwent a BT: in 15 patients, an autogenous connective tissue graft was employed (CT group); in the other 15 subjects, ADM was used as a subepithelial graft (ADM group). Prior to and 1 year after surgical treatment, the following clinical parameters were recorded: gingival recession (GR), probing depth (PD), clinical attachment level (CAL), width of keratinized tissue (KT), and gingival thickness (GT); the percentage of RC (%RC) was also calculated, and the data were statistically analyzed. The number of weeks needed to obtain complete healing with mature tissue appearance was also recorded. RESULTS: Both groups yielded significant improvements in terms of GR decrease, CAL and KT gain, and GT increase as compared to baseline values. The mean %RCs were 88.80 +/- 11.65% and 83.33 +/- 11.40% in the CT and ADM groups, respectively. Complete RC was observed in 46.6% of patients from the CT group, and 26.6% of the ADM group patients. No significant differences were observed between the two techniques for GR, CAL, and GT improvements; however, the CT group produced a significantly (P <0.01) greater increase in KT as compared to the ADM group. Complete healing of the surgical procedure was observed 6.20 +/- 1.01 and 8.93 +/- 1.33 weeks after suture removal in the CT and ADM groups, respectively (P <0.001). CONCLUSIONS: The CT and ADM subepithelial grafts were similarly able to successfully treat gingival recession defects; however, the CT group obtained a significantly greater increase in KT, and showed a quicker complete healing.

Guided tissue regeneration with a bioabsorbable polylactic acid membrane in gingival recessions. A histometric study in dogs.

BACKGROUND: The goal of this investigation was to histologically and histometrically evaluate the healing process of gingival recessions treated by guided tissue regeneration with bioabsorbable polylactic acid membranes (GTR group) and to compare it to that obtained with coronally positioned flaps (CPF group). METHODS: Gingival recessions were surgically created on the buccal aspect of the upper cuspids of 5 mongrel dogs. The defects (5x7 mm) were exposed to plaque accumulation for 3 months. The contralateral defects were then randomly assigned to each group. After 3 months of healing, the dogs were sacrificed and the blocks were processed. The histometric parameters evaluated included length of sulcular and junctional epithelium, connective tissue adaptation, new cementum, new bone, and defect coverage. RESULTS: The extension of the epithelium was 1.9 +/- 0.8 mm for the GTR-group and 3.0 +/- 0.9 mm for the CPF-group (P = 0.16). The connective tissue adaptation was 0.1 +/- 0.1 and 0.8 +/- 0.5 mm in the GTR group and CPF group, respectively (P = 0.051). The new cementum was 3.8 +/- 1.5 mm and 2.4 +/- 0.3 mm in the GTR group and CPF group, respectively (P= 0.16). Bone formation was 1.1 +/- 0.5 mm in the GTR group and 1.4 +/- 0.2 mm in the CPF group (P = 0.53). Histologically, the defect coverage observed was similar, 90.5% and 91.9% for the GTR group and the CPF group, respectively. No statistical differences in any of the parameters could be detected. CONCLUSIONS: Within the limits of this study, it can be concluded that both procedures resulted in a favorable healing response with no significant difference between the treatments.

Connective tissue-bone onlay graft with enamel matrix derivative for treatment of gingival recession: a case report.

We describe a case of gingival recession in which root coverage and coronal bone regrowth were achieved after treatment with a connective tissue-bone graft and enamel matrix derivative. The connective tissue-bone graft was harvested from a maxillary edentulous area and then curved to fit the root surfaces of the maxillary left central and lateral incisors. Enamel matrix derivative was applied to the root surfaces, and the connective tissue-bone graft was fixed to the interdental bone by a titanium screw. Six months later, the exposed roots were covered with thick gingiva, and coronal regrowth of thick bone was evident at reentry surgery. This technique is useful for esthetic restoration placement with an intracrevicular margin on teeth with a thin, receding gingiva.

[Treatment of gingival recession with a coronally repositioned flap].

The treatment of an exposed root surface may be indicated for an aesthetic improvement of a gingival recession. The surgical technic depends on the type of the recession, the quality and the quantity of the keratinized gingiva apically or laterally from the recession. The purpose of this study is to evaluate the minimal quantity of keratinized gingiva necessary to obtain a root coverage. 10 recessions on maxillary cuspids were treated with coronally repositioned flap. Less than 3 mm of keratinized gingiva was present apically to the exposed root surface. All patients received oral hygiene instructions, plaque control and scaling and root planing. Gingival recession, width of keratinized gingiva and loss of attachment were measured at the time of surgery and three months postoperatively. The mean recession was 5.20 mm (+/- SE = 0.36) prior to treatment and the keratinized gingiva was 1.70 mm (+/- 0.16) high at T0. The mean gain of root coverage was 3.43 mm (+/- 0.29) at three months post-operatively. At T0 and 3 months post-operatively, the measures of recessions showed a statistically difference confirming the validity of the technic. The absence of correlation between initial height of keratinized gingiva and the coverage result (r = 0.05) indicates that initial width of keratinized gingiva does not affect the coverage results.

PubMed1989

[Gingival recession: what to do?].

The qualitative and quantitative character of the marginal gingiva is not the only cause of root exposure, as mechanical factors can favorize and/or aggravate gingival recession. Suggested therapy is dependent on patient motivation and the evolution of the lesions. Even though there are multiple possibilities for the treatment of gingival recession, one must remain prudent when restoring areas of root exposure, as no protocol exists today which can assure constant success.

Prevention of gingival recession following flap debridement surgery by subepithelial connective tissue graft: consecutive case series.

BACKGROUND: Surgical debridement with flap repositioning may result in significant gingival recession. This manuscript reports on a series of cases that were treated for deep periodontal pockets by flap debridement surgery combined with subepitheial connective tissue graft for the prevention of postoperative recession. METHODS: Fourteen patients (27 teeth) with deep periodontal pockets and bone loss in the mandibular central incisors area underwent flap debridement combined with subepithelial connective tissue graft. Probing depth, recession depth, and clinical attachment levels were recorded prior to surgery, 6 months post-surgery, and again 19 to 58 months post-surgery. RESULTS: Mean probing depth at baseline was 6.20 mm, while 6 months post-surgery it was 1.97 mm (P < 0.0001), and 19 to 58 months after surgery it was 1.32 mm. Clinical attachment level measurements followed the same pattern (baseline 9.37 mm, 6 months 3.29 mm, final examination 2.00 mm). While the mean recession depth at baseline was 3.17 mm, 6 months post-surgery it was reduced to 1.30 mm (P < 0.0001). Additional reduction in recession depth was recorded over time. CONCLUSION: Within the limitations of a single group study, the results suggest that flap debridement combined with subepithelial connective tissue graft, followed by maintenance therapy, is an effective procedure for maintaining long-term periodontal health and for prevention of postoperative gingival recession in the mandibular anterior dentition.

Cocaine-associated rapid gingival recession and dental erosion. A case report.

This case report chronicles the clinical presentation and unusual response to treatment of a patient with rapid gingival recession and dental erosion secondary to local cocaine application. The initial clinical diagnosis was necrotizing ulcerative periodontitis; only after several years of therapy did the patient voluntarily inform one of the therapists that cocaine had been regularly applied to the affected gingival sites. This case illustrates the importance of including cocaine application to gingival tissues in a differential diagnosis in cases of rapid gingival recession and dental erosion of unknown etiology.

Root coverage of advanced gingival recession: a comparative study between acellular dermal matrix allograft and subepithelial connective tissue grafts.

BACKGROUND: Acellular dermal matrix allograft (ADMA) has successfully been applied as a substitute for free connective tissue grafts (CTG) in various periodontal procedures, including root coverage. The purpose of this study was to clinically compare the efficiency of ADMA and CTG in the treatment of gingival recessions > or = 4 mm. METHODS: Seven patients with bilateral recession lesions participated. Fourteen teeth presenting gingival recessions > or = 4 mm were randomly treated with ADMA or CTG covered by coronally advanced flaps. Recession, probing depth, and width of keratinized tissue were measured preoperatively and 12 months postoperatively. Changes in these clinical parameters were calculated within and compared between groups and analyzed statistically. RESULTS: Baseline recession, probing depth, and keratinized tissue width were similar for both groups. At 12 months, root coverage gain was 4.57 mm (89.1%) versus 4.29 mm (88.7%) (P = NS), and keratinized tissue gain was 0.86 mm (36%) versus 2.14 mm (107%) (P < 0.05) for ADMA and CTG, respectively. Probing depth remained unchanged (0.22 mm/0 mm), with no difference between the groups. CONCLUSIONS: Recession defects may be covered using ADMA or CTG, with no practical difference. However, CTG results in significantly greater gain of keratinized gingiva.
