Analysis of the Community Periodontal Index of Treatment Needs--study on adults in France. IV. The significance of gingival recession.

A total of 1005 persons were examined using the CPITN criteria which were recorded for every tooth. All the teeth were also measured on both their buccal and lingual aspects to assess the amount of gingival recession. The combination of pocket depth and gingival recession was computed using a specially written program: 93.8 per cent of the teeth had 1 mm or less gingival recession; 82.5 per cent of the teeth with gingival recession did not present pockets; 26.6 per cent of all subjects had at least one tooth with gingival recession of 2 mm or more but only 9.9 per cent had at least one tooth with 2 mm or more gingival recession and a periodontal pocket.

A clinical study comparing the width of attached gingiva and the prevalence of gingival recessions.

One hundred preclinical year dental students were examined. Oral hygiene status and gingival condition were determined using the Plaque Index score (Silness & Löe 1964) and the Gingival Index score systems (Löe & Silness 1963). The width of the attached gingiva and the depth of the gingival pockets were evaluated. The gingival recessions were recorded and their heights measured from the CEJ to the gingival margin. No significant correlation was found between oral hygiene and gingival recession, oral hygiene and width of attached gingival conditions and width of attached gingiva. Only a negative correlation (P less than 0.05) was found between the width of attached gingiva and the number of gingival recessions. No statistically significant differences were observed in oral hygiene status and gingival conditions among three groups of students (without, with one and with two or more recessions, respectively). The roles of toothbrushing trauma and "adequate" width of attached gingiva in the etiology of gingival recessions are questioned.

Periodontal regeneration in gingival recession defects.

Surgical treatment of gingival recession defects aims at obtaining soft tissue coverage of exposed root surfaces and/or augmentation of gingival tissue dimensions. A variety of protocols have been developed to manage these clinical problems. Since one goal of periodontal therapy is the regeneration of the lost attachment apparatus of the tooth, full restoration of defect should be accomplished following mucogingival procedures. This implies regeneration of all periodontal structures, including formation of new cementum with inserting connective tissue fibers, alveolar bone regeneration and recreation of a functional and aesthetic morphology of the mucogingival complex. Animal and human histological studies have shown that healing at gingiva-root interface following pedicle flaps or free soft tissue grafts generally includes a long junctional epithelium with varying amounts of a new connective tissue attachment in the most apical aspect of the covered root surface. Limited bone regeneration has been observed. Adjunctive use of root conditioning agents and cell excluding, wound-stabilizing devices may amplify regenerative outcomes. Changes in the amount of keratinized tissue, which can significantly affect the aesthetic outcome of treatment, have been shown to depend on the interactions among various tissues involved in the healing process and the selected surgical procedure.

Correlation between mandibular central incisor proclination and gingival recession during fixed appliance therapy.

The purpose of this study was to determine whether proclination of mandibular central incisors during fixed appliance therapy results in gingival recession. Complete records of 67 patients (39 female and 28 male patients; mean age, 16.4 years; age range, 10-45 years) were used in this retrospective case-control study. Using pretreatment and posttreatment lateral cephalograms, the change in mandibular central incisor inclination was measured to divide the patients into an experimental group (proclination) and a control group (no proclination). Changes in clinical crown length were determined from pretreatment and posttreatment study models, and changes in gingival recession were determined from intraoral slides. Eight of the 67 patients exhibited a measurable increase in gingival recession of at least 0.5 mm, and 27 patients had an increase in clinical crown length of at least 0.5 mm. Statistical analyses showed no correlation between mandibular central incisor proclination and gingival recession or clinical crown length. A t-test analysis showed no statistically significant difference in gingival recession or change in clinical crown length between patients whose mandibular central incisors were proclined and those whose incisors were not proclined. Multiple regression analysis demonstrated that age, sex, race, treatment duration, extraction, treatment type, Angle classification, and proclination were not related to gingival recession or change in clinical crown length of mandibular central incisors. We conclude that the degree of proclination of mandibular central incisors during fixed appliance therapy was not correlated to gingival recession in this sample.

Subepithelial connective tissue grafts in the treatment of gingival recessions. A comparative study of 2 procedures.

Thirty (30) class I and class II recessions in 30 subjects were treated with a subepithelial connective tissue graft procedure. In one group (15 sites), the surgery was carried out in a traditional fashion: the epithelial collar of the graft was preserved and left exposed (CTG group). In the second group (15 sites), the epithelial collar of the graft was removed and the recession areas were conditioned with citric acid. The graft was then sutured and completely immersed under the facial flap which was coronally repositioned (CR group). Clinical assessments included probing depth, probing attachment level, surface area of the recession, and gingival width. These measurements were taken at baseline and at 6 months. In addition, an esthetic evaluation was done. The differences between treatments were not statistically significant except for the augmentation of gingiva (P < or = 0.05). Based on the midfacial measurements taken in the central area of the recession, the mean percentage of root coverage was 69.2%. In the CR group, 3 of the 15 recessions exhibited complete root coverage; the gingival augmentation was 65.5%. In the CTG group, 5 of the 15 recessions exhibited complete root coverage; the gingival augmentation was 94.4%. The mean surface area of root exposure was reduced from 13.82 mm2 and 13.67 mm2 to 2.15 mm2 and 2.34 mm2 for the CR group and the CTG group, respectively. One-hundred percent (100%) of good-to-moderate esthetic results were found by a panel of independent examiners; there was tendency toward better results in the CR group.(ABSTRACT TRUNCATED AT 250 WORDS)

Treatment of gingival recession: comparative study between subepithelial connective tissue graft and guided tissue regeneration.

BACKGROUND: Various procedures have been proposed to treat gingival recession, but few studies compare these procedures to each other. The purpose of this study was to evaluate a clinical comparison of subepithelial connective tissue graft (SCTG) and guided tissue regeneration (GTR) with a collagen membrane in the treatment of gingival recessions in humans. METHODS: Twenty-four defects were treated in 12 patients who presented canine or pre-molar Miller Class I and/or II bilateral gingival recessions. Both treatments were performed in all patients, and clinical measurements were obtained at baseline and 18 months after surgery. These clinical measurements included gingival recession height (GR), root coverage (RC), probing depth (PD), keratinized tissue width (KT), and final esthetic result. RESULTS: Both SCTG and GTR with a bioabsorbable membrane and bone graft demonstrated significant clinical and esthetic improvement for gingival recession coverage. The SCTG group was statistically significantly better than GTR for height of GR (SCTG = 0.2 mm, GTR = 1.12 mm, P= 0.02) and KT (SCTG = 4.58 mm, GTR = 2.5 mm, P<0.0001). However, PD was statistically significantly better for GTR than SCTG treatment (GTR = 1.66 mm, SCTG = 1.00, P= 0.01). The 2 procedures were statistically similar in root coverage (SCTG = 95.6%, GTR = 84.2%, P= 0.073). The esthetic condition after both treatments was satisfactory (P= 0.024). CONCLUSIONS: It was concluded that the gingival recessions treated with the SCTG group were superior for GR, RC, and KT clinical parameters, while GTR demonstrated better PD reduction. The final esthetic results were similar using both techniques.

Gingival recession treatment: guided tissue regeneration with bioabsorbable membrane versus connective tissue graft.

BACKGROUND: Gingival recession represents a significant concern for patients and a therapeutic problem for clinicians. Several techniques have been proposed to achieve root coverage. The purpose of this randomized clinical trial was to evaluate the effect of a guided tissue regeneration (GTR) procedure in comparison to connective tissue graft (CTG) in the treatment of gingival recession defects. METHODS: Twelve patients, each contributing a pair of Miller Class I or II buccal gingival recessions, were treated. In each patient one randomly chosen defect received a poly(lactic acid)-based bioabsorbable membrane, while the paired defect received a CTG. Clinical recordings included oral hygiene standards and gingival health, recession depth (RD), recession width (RW), probing depth (PD), clinical attachment level (CAL), and keratinized tissue width (KT). RESULTS: Mean RD statistically significantly decreased from 2.5 mm presurgery to 0.5 mm with GTR (81% root coverage), and from 2.5 mm to 0.1 mm with CTG (96% root coverage), at 6 months postsurgery. Prevalence of complete root coverage was 58% for the GTR group and 83% for the CTG group. Mean CAL gain was 2.0 mm for the GTR group and 2.2 mm for the CTG group. No statistically significant differences between treatment groups were observed for changes in RD, RW, PD, CAL, and KT. CONCLUSIONS: Treatment of human gingival recession defects by means of either GTR or CTG results in clinically and statistically significant improvement of the soft tissue conditions of the defect when pre- and post-treatment measurements were compared. Although differences between CTG and GTR in mean root coverage and prevalence of complete coverage consistently favored the CTG procedure, the differences in measurements were not statistically significant.

Treatment of adjacent gingival recessions with subepithelial connective tissue grafts and the modified tunnel technique.

OBJECTIVE: There has been great interest in the treatment of gingival recession defects, especially with subepithelial connective tissue grafting. Recent advances have focused on subepithelial connective tissue grafting by the tunnel technique. In this clinical study, a modified periodontal plastic surgery technique for coverage of adjacent gingival recessions was performed. This surgical modification was based on the tunnel technique without vertical incisions, where the partial dissection was converted to a full-thickness dissection at the mucogingival area to supply more blood vessels. METHOD AND MATERIALS: Patients, each contributing at least two adjacent buccal gingival recessions, were treated. Subepithelial connective tissue grafting was used to cover the defects. Gingival recession, probing depth, and attachment level were measured at baseline and 8 months posttreatment. RESULTS: There were statistically significant improvements in attachment level and gingival recession after 8 months; the mean gain in attachment was 3.67 mm and the mean root coverage was 3.28 mm, which translated to mean root coverage of 95%. CONCLUSION: These findings suggest that subepithelial connective tissue grafting with a modified tunnel approach, in which the partial-thickness flap is converted to a full-thickness flap in a coronoapical direction, results in adequate early healing and highly predictable root coverage in adjacent gingival recessions.

3-year observations on gingival recession in mandibular incisors in children.

28 children aged 6-13 years, with gingival recession localized to mandibular incisors, were monitored longitudinally to evaluate any changes of the labial periodontal tissues. Measurements included dental plaque, gingival inflammation, gingival recession, probing depth, probing attachment level, keratinized and attached gingiva. Following baseline examination, the incisors were observed at yearly intervals over 3 years. The results showed that a high level of oral hygiene was maintained and that gingival inflammation occurred only to a minor degree throughout the observation period. Gradual reductions in the amount of gingival recession and probing attachment levels took place in all children except for 1 of the subjects with 1 severely malpositioned tooth. Probing depths and widths of keratinized and attached gingiva remained relatively unchanged. The finding that gingival recession in mandibular incisors in young children often improves over time suggests that preventive or reparative treatment in this part of the developing dentition may not be necessary. Decisions about such treatment should be postponed until any spontaneous improvement has taken place.

The prevalence and distribution of gingivitis and gingival recession in children and young adults in Lagos, Nigeria.

The prevalence and distribution of gingivitis and gingival recession were studied in 820 Nigerians aged 15, 19, 20 and 21 years sampled from Lagos educational establishments. The prevalence of gingivitis was relatively high at all ages. There was a high degree of correlation between the prevalence of gingivitis affecting mouths, papillae and margins. It therefore would appear that in those mouths with gingivitis, the proportion of affected papillae or margins to those not affected varies only within narrow limits. Although the peak prevalance of gingivitis was observed in the 15-year olds, the prevalence of gingival recession was higher in the 21-year-old students than in those aged 15 years. Gingival recession may be a sequel of gingivitis resulting from apical proliferation of the epithelial attachment with destruction of the subjacent periodontal tissues. Hence gingivitis should be distinguished from gingival recession in its prevalence and distribution.

Acellular dermal matrix allograft used alone and in combination with enamel matrix protein in gingival recession: histologic study in dogs.

Gingival recession was created in six mongrel dogs. The dogs were divided into two groups based on treatment: group 1--AlloDerm only, group 2--AlloDerm + Emdogain. The histologic results were compared. At the end of the study, the mean values were, for groups 1 and 2, respectively: 0.06 and 0.32 mm for cementum regeneration; -0.75 and -0.86 mm for bone regeneration; -2.15 and -3.11 mm for attachment level; and 4.90 and 5.51 mm for defect extent. The epithelial formation parameter was 2.88 mm in group 1 and 2.15 mm in group 2, which was a statistically significant difference. It could be concluded that Emdogain did not result in beneficial effects when associated with AlloDerm.

Coronally positioned flap with or without acellular dermal matrix graft in gingival recessions: a histometric study.

PURPOSE: To evaluate, histometrically, the healing of gingival recession treated by coronally positioned flaps (CPF) with or without acellular dermal matrix (ADM) as a subepithelial graft. METHODS: Gingival recessions were created on the upper cuspids of six dogs and were randomly assigned to: CPF+ADM (ADM group) or CPF alone (CPF group). After 4 months, the dogs were sacrificed, and the histometric measurements were performed. RESULTS: The epithelial length was 2.28 + 0.92 mm and 2.10 + 0.46 mm for the ADM and CPF groups, respectively (P=0.74). The connective tissue adaptation was 0.05 + 0.08 mm for the ADM group and 0.06 + 0.08 mm for the CPF group (P=0.36). The new cementum was 2.35 + 1.55 mm and 2.90 + 0.96 mm in the ADM and CPF groups, respectively (P=0.53). The new bone was 0.60 + 1.36 mm for the ADM group and 0.35 + 0.82 mm for the CPF group (P=0.53). The gingival recession was -0.88 + 1.33 mm in the ADM group and -0.21 + 0.22 mm in the CPF group (P=0.21). The gingival thickness was 1.63 + 0.28 mm in the ADM group and 1.16 + 0.20 mm in the CPF group (P=0.002).

Expanded mesh connective tissue graft for the treatment of multiple gingival recessions.

BACKGROUND: The connective tissue graft procedure is an effective method to achieve root coverage. Although multiple sites often need grafting, the palatal mucosa supplies only a limited area of grafting material. The expanded mesh graft provides a method whereby a graft can be stretched to cover a larger area. The aim of this study was to determine the effectiveness and the predictability of expanded mesh connective tissue graft (e-MCTG) in the treatment of multiple gingival recessions. METHODS: Fifty-two buccal gingival recessions were treated in 10 systemically healthy patients. Fifteen recession treated operation sites with at least three adjacent Miller Class I and/or II recessions were performed. The connective tissue graft obtained from the palatal mucosa was expanded to cover the recipient bed, which was 1.5 times larger than the graft. Clinical measurements recorded at baseline and 12 months postoperatively included gingival recession depth (RD), gingival recession width (RW), percentage root coverage (RC), probing depth (PD), width of keratinized tissue (KT), and clinical attachment level (CAL). RESULTS: Twelve months after surgery, a statistically significant gain in CAL (3.2 +/- 0.8 mm, P < 0.001) and increase in KT (1.2 +/- 0.4, P < 0.001) were assessed. In 80% of the treated sites, 100% RC was achieved (mean 96%). CONCLUSIONS: The results of this study demonstrated that the use of e-MCTG technique allowed the treatment of multiple adjacent recessions with adequate wound healing and highly predictable root coverage. This procedure can be applied favorably in treating multiple gingival recessions in one surgery.

The association between spontaneous reversal of gingival recession in mandibular incisors and dentofacial changes in children. A 3-year longitudinal study.

In a previous 3-year longitudinal study, reversal of gingival recession in mandibular incisors was observed for 16 out of 28 participating children aged 6-13 years (Andlin-Sobocki et al., 1991). In the present report various dentofacial conditions that might be associated with this reversal were evaluated from dental casts and cephalometric radiographs by comparing the 16 children with spontaneous reversal of gingival recession (Group Rev) to the 12 children with persisting gingival recession (Group Per). Dental casts and cephalometric radiographs were obtained at baseline and after three years. The findings indicate that the children with persisting gingival recession tended to have a particular facial morphology and incisor pattern. They were likely to have a larger basal bone discrepancy between the maxillary and mandibular jaws, with somewhat more proclined and more irregularly positioned mandibular incisors. Although a reduction in incisor irregularity and a slight increase in anterior arch widths occurred for both groups during the observation period, the tooth alignment situation in Group Per at the end of the observation period was similar to that of Group Rev at baseline. Additionally, in Group Rev all facially deviating incisors with recession at baseline had self-corrected at 3 years. This was not the case for Group Per. Thus, spontaneous reversal of gingival recession in mandibular incisors seem to be related to developmental changes in the dentition favouring incisor alignment.

Gingival recession and its association with calculus in subjects deprived of prophylactic dental care.

This paper describes the prevalence and severity of gingival recession in Tanzanian adults covering the age range from 20 to 64 years. In addition, it attempts to assess the relationship between the degree of gingival recession and the presence and amount of calculus. In the 20-34 years age group recession occurred in > or = 32% of the buccal, > or = 25% of the lingual, and > or = 13% of the approximal surfaces. These %s increased to > or = 64%, > or = 52%, and > or = 48%, respectively, in the 45-64 years age group. In the 20-34 years age group, lingual surfaces of mandibular incisors and canines followed by buccal surfaces of these teeth were the sites most severely affected with gingival recession. With increasing age, all sites became gradually more severely affected, particularly the buccal and lingual surfaces of the maxillary first molar. The lingual surfaces of mandibular incisors exhibited on an average 1.3 mm, 2.4 mm and 3.2 mm recession in the 20-34 years, 35-44 years and 45-64 years age group, respectively. Most of the correlation coefficients between gingival recession and calculus at the individual tooth surface in three age groups were statistically significant. The highest correlation coefficients (0.50-0.67) were found in the youngest (20-34 years) age group at the lingual surfaces of the mandibular incisors, canine and first premolar and at the buccal surfaces of the mandibular incisors. Based on these findings, the working hypothesis is advanced that longstanding calculus is an important determinant in the onset of gingival recession at sites exhibiting pronounced recession at a young age in populations deprived of prophylactic dental care.

Gingival recession: a cross-sectional clinical investigation.

In this cross-sectional study, risk and potentially causative factors of gingival recession were examined and their relationship to apical migration of the gingival margin evaluated. Thirty eight patients (18-60 years), displaying one or more sites with gingival recession but without any significant periodontal disease participated. A total of 28 parameters were evaluated in both 'test' teeth (50 teeth with gingival recession) and 'control' teeth (50 contralateral teeth). The results revealed that gingival margin recession was associated with both high inflammatory and plaque scores, with decreased widths of keratinized and attached gingiva and with the subjects' toothbrush bristle hardness.

[Surgical methods used in the treatment of local gingival recession].

Surgical methods used for repair of gingival recession are reviewed. Modern methods and means of plastic periodontal surgery solve many esthetic problems. The prognosis of the results of gingival plasty in cases of recession of different classes is now becoming more and more favorable. The method of purposeful tissue regeneration is a good supplement to surgical treatment of gingival recession.

Gingival recession defects and guided tissue regeneration: a review.

The last decade has seen an increasing number of clinical reports on guided tissue regeneration (GTR) for reconstruction of gingival recession defects. This article reviews the value of GTR in the management of gingival recession defects based on records from such reports. Studies and case-series using nonresorbable and bioresorbable membranes, studies comparing GTR to the subepithelial connective tissue graft (CTG) procedure, and histologic reports of healing following GTR, published in the English language from 1985 to 2000, were identified using a Medline search and were included in the data-base for this review. The Following pre- and post-treatment data were collated and evaluated for each of the reports: gingival recession depth, probing depth, clinical attachment level, and width of the keratinized gingiva. In perspective of the limitations of the studies reviewed, it has been shown that GTR may be used for reconstruction of gingival recession detects. Importantly it has not been shown that GTR provides an added clinical benefit for the patient treatment planned for reconstruction of gingival recession defects. i.e. GTR does not appear to offer a significant advantage over mucogingival procedures such as the connective tissue graft or the advanced flap procedure. It is imperative to recognize inherent technical difficulties associated with GTR including primary would closure and secondary membrane exposure: membrane exposures being negatively correlated to desired clinical outcomes. Also, membrane exposures appear consistently more common in smokers than in non-smokers. It is also imperative to recognize shortcomings and adverse effects including space maintenance and unacceptable foreign body reactions associated with some bioresorbable GTR technologies.
