Treatment of single gingival recessions using biofunctionalized collagen matrix: A case series.

Connective tissue graft substitutes have been used widely to overcome autogenous graft limitations. Nevertheless, they do not provide comparable results in the treatment of periodontal and peri-implant soft tissue defects. Based on the principles of tissue-engineered materials, injectable platelet-rich fibrin (i-PRF) has been combined with collagen matrices (CMs) to enhance their clinical efficacy. To the best of our knowledge, this is the first case series demonstrating the use of i-PRF for the biofunctionalization of a volume-stable collagen matrix (VCMX) as an adjunct to coronally advanced flap (CAF) to treat single gingival recession (GR) defects. The study included 10 patients. Bleeding on probing, probing depth, GR height, clinical attachment level, esthetics, and dentin hypersensitivity were evaluated. After 6 months, a significant GR reduction (RecRed: 2.15 ± 0.7mm; p = 0.005) and percentage of root coverage (% RC) of 81.13% were observed. Additionally, 40% of the sites showed complete root coverage. Gingival thickness increased 0.64mm. Patient-centered evaluations demonstrated dentin hypersensitivity and esthetics improvements by the end of follow-up. VCMX biofunctionalized with i-PRF associated with CAF technique showed promising clinical outcomes in the treatment of single RT1 GR defects.

A new volume-stable collagen matrix (VCMX) to treat single gingival recession associated with partially restored non-carious cervical lesions: a case series.

Collagen matrixes have been developed as possible connective tissue graft substitutes to overcome patient discomfort, undesired palatal healing, and the limited amount of donor tissue. The aim of this case series is to assess a coronally advanced flap (CAF) with a new volume-stable collagen matrix (VCMX) to treat single gingival recession (GR) associated with partially restored non-carious cervical lesions (NCCL). Twelve patients diagnosed with single GR RT1 + NCCL (B+) were included in this study and received a restorative - partial resin composite with apical margin 1 mm beyond the estimated cementoenamel junction (CEJ) - and a surgical approach - CAF+VCMX. Clinical and patient-centered assessments were recorded at baseline and 6 months postoperatively from ten patients. Significant recession reduction (RecRed:2.1mm), clinical attachment level gain (CAL:1.34mm), and combined defect coverage (CDC) of 51.67% were observed at 6 months. The estimate root coverage (RC) was 69.48%, obtained using the estimated CEJ. No difference in keratinized-tissue width (KTW) was observed over time. A gain in gingival thickness (GT) of 0.42 mm was observed after 6 months (p=.002) and an improvement in patient satisfaction due to better esthetics (p<.001). Within the present study's limits, CAF plus VCMX provided significant improvement in treating single GR combined with partially restored NCCL (B+).

Mixed-Thickness Tunnel Access (MiTT) through a Linear Vertical Mucosal Incision for a Minimally Invasive Approach for Root Coverage Procedures in Anterior and Posterior Sites: Technical Description and Case Series with 1-Year Follow-Up.

The goal of this article was to introduce a new root coverage (RC) technique, the mixed-thickness tunnel access (MiTT) technique, which approaches a full-split design and intends to augment soft tissues coronal to the gingival margin. It was shown step-by-step, and the results were presented in a case series. Healthy individuals (non-diabetics) and non-smokers with gingival recession (GR) type 1 or 2 (RT1 or RT2) were included. After evaluation, prophylaxis was performed 14 days before the surgical procedure. During the surgical appointment, one or two vertical incision(s) on the mucosa (around 1-2 mm apical to the MGJ), lateral to the papilla base, was/were performed after anesthesia. Initially, there was a partial incision to detach the mucosa of the muscles (split design). It was permitted (but not mandatory) to perform intrasulcular incisions. Through the vertical incision, internally, subperiosteal access from the MGJ toward the gingival margin (coronally) was performed to create a full-thickness tunnel. Then, communication from the vertical incision with the gingival sulcus and the papilla base occurred, keeping the papilla tip intact. A connective tissue graft was harvested and inserted through the linear incision or intrasulcularly. There were interrupted sutures. An adjunctive material may be applied (e.g., Endogain). The root coverage was measured using a periodontal probe and considered fully covered when the gingival margin was 1 mm coronal to the cementum-enamel junction (CEJ). Nine healthy individuals (seven females and two males) aged 19 and 43 were enrolled. They were treated following the MiTT steps. Four cases had a single GR; two patients had two teeth involved; and three others had three or four GR. There were seven cases of RT1 and two RT2. All RT1 cases achieved 100% RC, while the mean RC obtained for RT2 was around 80%. The MiTT technique can be considered a more straightforward approach for minimally invasive surgical techniques, which is a feasible option to treat RC with a high success rate, predictability, and esthetic preservation. Therefore, there is a technical sensitivity to performing the full-split design procedure.

Treatment of deep single RT2 and RT3 antero-mandibular gingival recessions with a combination of surgical techniques: A case series study.

To evaluate root coverage (RC) in deep single antero-mandibular RT2 and RT3 gingival recessions (GR) and to investigate the influence of several factors in RC. Fifteen single antero-mandibular GR with a minimum depth of 3 mm were consecutively treated with a new one-stage technique (laterally positioned flap with a tunnel access and a connective tissue graft). At baseline and at 12-month follow-up, the percentage of mean root coverage (%MRC), the recession reduction (RecRed), complete root coverage (CRC) and the gain of keratinized tissue width (KTW) were assessed. Descriptive, intergroup comparative and correlation analyses were performed. At 12 months, a %MRC of 77.29 ± 21.48% with a mean RecRed of 4.10 ± 1.51 mm was achieved. The %MRC was 84.71 ± 21.08% in RT2, and 62.43 ± 14.17% in RT3. The mean gain of KTW was 2.10 ± 0.89 mm, with a mean gain of 2.0 ± 1.03 mm for RT2 and 2.3 ± 0.57 mm for RT3. CRC was observed in six cases, all of them being RT2. A positive association was found between the %MRC and the initial position of the tooth and of both papillae. This technique might be a valuable approach for the treatment of deep single antero-mandibular RT2 and RT3 recessions, even in malpositioned teeth. A combination of different surgical techniques could provide greater vascularization to the CTG especially in malpositioned teeth in sextant V with a large avascular area to be covered.

Clinical evaluation of periosteal pedicle flap in the treatment of gingival recessions for esthetic root coverage: A randomized controlled clinical trial.

Root coverage using subepithelial connective tissue graft (SCTG) is gold standard with few drawbacks such as requirement of second surgical site, reduced donor tissue availability, and increased surgical complications and pain. Periosteal pedicle graft (PPG) due to its rich source of pluripotent stem cells and nonrequirement of second surgical site could be a successful alternative for invasive SCTG. Therefore, current research aims to compare the amount of root coverage obtained with PPG to SCTG. Fifty-two single gingival recessions were included in the sample, with 26 patients allocated to the SCTG (control) and PPG (test) groups at random. At baseline, 3, and 6 months after surgery, clinical measurements of probing depth, clinical attachment level (CAL), recession depth (RD), recession width (RW), and width of keratinized tissue were taken. Both procedures, i.e., SCTG and PPG, resulted in root coverage to a variable extent and a significant decrease in RD (1.69, 1.38 mm in SCTG and PPG groups, respectively) and RW, CAL gain is found in both the groups without any intergroup statistical variance. Complete root coverage (CRC) was obtained in 14 out of 26, i.e., 53.8% defects in both SCTG and PPG groups. A better comfort level is found in the group treated with PPG. Gingival recessions can be successfully treated with PPG, which has predictability comparable to SCTG and does not require a second surgical site.

Aim: The aim of this retrospective study was to evaluate the effectiveness of coronally advanced flap and connective tissue graft (CAF+CTG) in the treatment of gingival recessions (GR).Method: Periodontal records of 32 single and multiple GR in 11 patients treated with CAF+CTG were selected for the study. According to Cairo’s classification, recession type 1 defects were included. Recession depth (RD), probing depth (PD) and clinical attachment level (CAL) were assessed at baseline and follow-ups. Mean root coverage (MRC) and complete root coverage (CRC) were evaluated. Compliance with supportive periodontal therapy (SPT) was also determined.Results: Mean age of 11 patients was 29.6±4.4 years. The mean observation time of 32 recessions was 37.6±24.2 months. All clinical parameters showed an improvement between baseline and the latest follow-up. After treatment with CAF+CTG, MRC was 92.6±13.1% and CRC was achieved in 75% of the recessions. Compliance to SPT was calculated at 83.3%.Conclusion: The use of CAF+CTG yielded positive outcomes in terms of all clinical parameters and complete root coverage in Cairo recession type 1 defects with a mean observation period of &amp;gt;3 years. The results of the present study confirm the use of CAF+CTG as a gold standard for the treatment of gingival recessions.

Comparison between connective tissue graft and xenogeneic acellular dermal matrix to treat single gingival recession: A data reanalysis of randomized clinical trials.

There are few studies comparing xenogeneic acellular dermal matrixes (XDMs) with connective tissue graft (CTG) to treat single gingival recession (GR). The present study involved a reanalysis of previous studies and comparison of CTG or XDM to treat single RT1/GR. Fifty patients from three previous randomized clinical trials treated either by CTG (n=25) or XDM (n=25) were evaluated after 6-month. Clinical, patient-centered, and esthetic parameters were assessed. Pearson's correlation and regression analyses were also performed. Greater recession reduction (RecRed), percentage of root coverage (%RC), and complete root coverage (CRC) were observed in the CTG group (p ≤ 0.02). Gingival thickness (GT) and keratinized tissue width (KTW) gains were higher in the CTG group. The CTG group showed better esthetic at 6-month. Logistic analyses reported that GT([OR]=1.6473 ) and papilla height (PH) (OR=8.20) are predictors of CRC. GT*XDM interaction was a negative predictor of CRC (OR=7.105-5 ). GT at baseline acted as a predictor of RecRed in both groups (p=0.03). The XDM graft impacted RecRed and %RC negatively. Baseline PH was a predictor of %RC for both grafts. CTG was superior for treating RT1/GR, providing better root coverage outcomes and tissue gains over time. GT, PH, and graft type were classified as predictors of CRC. CTG presented better outcomes to treat single RT1 gingival recession when compared to the XDM.

Double Lateral Sliding Bridge Flap versus Laterally Closed Tunnel for the Treatment of Single Recessions in the Mandibular Anterior Teeth: A Pseudorandomized Clinical Trial.

(1) Background: This study compared the clinical and esthetic results of the double lateral sliding bridge flap (DLSBF) and the laterally closed tunnel (LCT) techniques, with a subepithelial connective tissue graft (SCTG), for the treatment of single Miller class II-III recessions in the mandibular anterior teeth. (2) Methods: This pseudorandomized clinical trial evaluated 14 patients, 7 of whom were part of the DLSBF + SCTG group, with an average follow-up of 58.7 ± 24.0 months, and 7 of whom were in the LCT + SCTG group, with an average follow-up of 16.7 ± 3.3 months. Clinical and esthetic evaluations of the following parameters were performed and the results for the two groups were compared: gingival recession depth, probing depth, keratinized tissue width, gingival thickness, percentage of root coverage and root coverage esthetic score. (3) Results: After the follow-up period, each technique provided evidence of a reduction in recession depth and clinical attachment level, as well as increased keratinized tissue width and gingival thickness, with statistically significant differences (p < 0.05). The analysis showed that gingival recession depth decreased less in the DLSBF group (4.3 ± 1.2 mm to 0.6 ± 1.1 mm) than it did in the LCT group (4.9 ± 1.1 mm to 0.1 ± 0.4 mm), but no significant difference was found between the two groups. Similarly, a greater reduction in the clinical attachment level parameter was observed in the LCT group, while a greater increase in gingival thickness was observed in the DLSBF group. The presence of scars was the only parameter for which statistically significant differences (p < 0.05) between the two study groups were found. (4) Conclusions: Within the limitations of the study, it indicates that the LCT + SCTG technique may be considered an optimal technique in terms of reducing gingival recession depth, complete root coverage and esthetic results for the treatment of single gingival recessions in the mandibular anterior teeth.

Does the subepithelial connective tissue graft in conjunction with a coronally advanced flap remain as the gold standard therapy for the treatment of single gingival recession defects? A systematic review and network meta-analysis.

The aim of this systematic review and network meta-analysis (NMA) was to assess the efficacy of a bilaminar root coverage technique consisting of the combination of an autogenous subepithelial connective tissue graft (SCTG) and a coronally advanced flap (CAF) compared with the five most indicated alternative approaches for the treatment of single gingival recession defects (GRD). The protocol of this PRISMA 2020-compliant systematic review was registered in PROSPERO (CRD42020221362). Three electronic databases were searched up to September 30, 2021 to identify randomized controlled trials that involved the treatment of single GRD without interproximal tissue loss via root coverage procedures. A frequentist NMA was conducted for complete root coverage (CRC), mean root coverage (MRC), and keratinized tissue width (KTW) changes. A total of 38 studies reporting on 830 patients and 1,265 GRD were included. SCTG + CAF was ranked as the most efficient treatment approach for MRC, CRC, and KTW gain at 6 and 12 months after surgery, except for MRC at the 12-month follow-up where enamel matrix derivative plus CAF exhibited superior results. SCTG + CAF can be considered the gold standard for the treatment of single GRD.

Recession width evaluation after the use of Advanced PRF (A-PRF) verus subepithilial conncective tissue graft (SCTG) in combination with coronally advanced flap in treatment of gingival recession

Objective: To evaluate the amount of recession width following the use CAF and advanced platelet rich fibrin (A-PRF) compared to CAF with SCTG in the treatment of single gingival recession. Materials and Methods: Twenty gingival recession defects were randomly assigned to receive either CAF+SCTG (n=10) or CAF+A-PRF (n=10). Recession width in mm was assessed at 3, 6 and 9 months post-operatively. Results: Patients in test group (CAF+A-PRF) reported 2.13 ± 0.35 recession width at 3 months, 2.00 ± 0 after 6 months. While, finally decreased to 1.25±1.04 after 9 months. In the control group (CAF+SCTG), the amount of recession width recorded 1.00 ± 1.07 at 3 months, while, after 6 and 9 months decreased to 0.5 ± 0.93. Conclusion and recommendation: There was no statistically significant difference between the two studied groups after 9 months. While, A significant difference reported at 3 and 6 months. Further studies with larger sample size and longer follow-up is needed.

The effectiveness of allogeneic dura mater for the preventive surgical treatment of single and multiple gingival recessions before orthodontic treatment with fixed orthodontic appliances: a clinical research

Relevance. Gingival recessions are frequent during or after orthodontic treatment with fixed appliances (65.0-86.7%). They are usually observed in anterior teeth, especially in teeth bodily movements along an archwire outside the bone or in buccal/ labial tipping more than five degrees along the axis (35%). Pre-existing recessions worsen during orthodontic treatment with fixed appliances and up to 5 years after the treatment (47%). The treatment of recessions during or after the orthodontic treatment is not strategically reasonable: the relapse rate is high, and the treatment implies large-scale surgical interventions, including osteoplastic surgery; it is more often performed with free gingival de-epithelized graft after the treatment, which has many comparative disadvantages. Purpose – the study aimed to evaluate the effectiveness of a graft material (allogeneic dura mater) to eliminate gingival recessions before orthodontic treatment or to create/ thicken the volume of the gum buccally/ labially to prevent rec eding gum during or after orthodontic treatment.Materials and methods. The paper presents and closely analyzes preventive surgical treatment in a patient with pretreatment gingival recessions.Results. In all cases, using the dura mater demonstrates a positive clinical result by all parameters of the gingival recession assessment. The percentage of root coverage is 100% in all teeth.Conclusion. Preventive surgical treatment is reasonable in all cases as it eliminates the need for repeated interventions, excludes the onset of gingival recessions during or after orthodontic treatment, as well as the reappearance of gingival recessions. Dura mater is effective and safe in all cases; the response to surgery is normal, dura mater allows avoiding a second surgical field. We recommend including it in the standard protocol of orthodonti c treatment.

Treatment efficacy of gingival recession defects associated with non-carious cervical lesions: a systematic review.

PurposeThis systematic review aimed to compare the efficacy, defined in terms of the mean percentage of root coverage (mRC), of surgical treatment approaches combined with adhesive restorations of non-carious cervical lesions (NCCLs) to that of root coverage alone in patients with a single gingival recession (GR) and NCCL.MethodsA literature search was conducted to identify longitudinal studies reporting the mRC following treatment for the correction of GR defects associated with NCCLs using a combination of surgical and restorative techniques in systemically and periodontally healthy patients.ResultsThe search resulted in the retrieval of 12,409 records. Seven publications met the inclusion criteria for the qualitative synthesis of data. The mRCs ranged from 69% to 97%. In the medium term, the gingival margin position was more stable when a connective tissue graft (CTG) was used, independently of whether restoration of teeth with NCCLs was performed.ConclusionsThe strength of the evidence was limited by methodological heterogeneity in terms of study design as well as the unit and period of analysis, which precluded a meta-analysis. Although no definitive conclusion could be drawn due to the lack of sufficient evidence to estimate the effectiveness of the interventions, CTG-based procedures contributed to gingival margin stability regardless of the performance of restoration to treat NCCLs.

Gingival Recession Treatment with the Use of Xenogeneic Matrix: Optimization of Patient-Centered Outcomes by the Digital Soft Tissue Design

Objective: To evaluate the impact of the originally-developed approach aimed at pre-treatment graphical modelling of soft-tissue changes (digital soft tissue design) for the optimization of patient-centered outcomes after Class I and Class II single gingival recessions treatment with the use of a xenogeneic dermal matrix. Material and Methods: Patients enrolled in the study group received single gingival recession treatment via CAF+XDM method supported by pre-treatment graphical modelling of potential soft-tissue changes (digital soft tissue design), while patients enrolled in the control group received single gingival recession treatment via CAF+CTG method with no pre-treatment graphical modeling of gingival level changes. Patient-centered outcomes were measured by visual analogue scale, OHIP-14, and Mahajan's scales. Results: Realization of pre-treatment graphical modelling of soft-tissue changes supported the achievement of better patient-centered outcomes, such as root coverage (p<0.05), surgical phase (p<0.05), post-surgical phase (p<0.05), cost-effectiveness (p<0.05) and diagnostics and patient-orientation (p<0.05) based on patient's personal perception grades. Conclusion: Patient-centered results were found to be more successful within the group using the xenogeneic type of graft accompanied with the implementation of pre-treatment graphical modeling of soft tissue changes, which helped to balance patients' pre-operative expectations and post-operative satisfaction with the received results, reduce post-operative morbidity and improve oral health-related quality of life.

Comparison of two types of xenogeneic matrices to treat single gingival recessions: A randomized clinical trial.

Xenogeneic matrices (XMs) have been increasingly used for root coverage procedures. This study compared the use of two types of XM (collagen matrix [CM] and xenogeneic acellular dermal matrix [XDM]) associated with the coronally advanced flap technique (CAF) to treat single gingival recessions. Seventy-five patients presenting single RT1 gingival recession were treated by CAF (control group, n=25), CAF+CM (test group 1, n=25), or CAF+XDM (test group 2, n=25) and completed 6-month follow-up. Clinical, patient-centered, and esthetic assessments were performed and intra- and intergroup differences were analyzed. At 6 months, the mean recession reduction for CAF, CAF+CM, and CAF+XDM was 2.4 ± 0.8mm, 2.4 ± 0.9mm and 2.1 ± 0.8mm, respectively (P>0.05). The corresponding mean percentage of root coverage was 78.9% ± 26.2% for CAF, 78.0% ± 28.5% for CAF+CM, and 65.6% ± 26.9% for CAF+XDM (P>0.05). Dentin hypersensitivity and esthetic conditions showed significantly improvements in all groups. Test groups presented significant gains in gingival thickness (GT; CAF+CM: 0.4 ± 0.3mm; CAF+XDM: 0.4 ± 0.2mm) compared to the control group (CAF: 0.0 ± 0.1mm; P<0.05). The CAF, CAF+CM, and CAF+XDM treatments each provided similar results in the treatment of single gingival recessions. The addition of either CM or XDM to CAF increases the GT.

Clinical evaluation of root coverage using coronally positioned flap associated with acellular dermal matrix allograft in single-type recession defects. A retrospective study.

The aim of this study was to conduct a retrospective assessment of the clinical results at 6,12 and 24 months of root coverage in single gingival recessions using coronally positioned flap and acellular dermal matrix allograft. Clinical records were collected from 16 patients with single gingival recessions who visited a private practice in Periodontics in 2005 and 2006. They were treated through a coronally positioned flap and acellular dermal matrix allograft. The following periodontal parameters were recorded at baseline, 6, 12 and 24 months: Recession Depth, Recession Width, Probing Depth, Clinical Attachment Level, Keratinized Tissue Width, Plaque Index, Gingival Index and Sensitivity. The percentage of root coverage was 91.18 ± 21.26 at 6 months, 90.18 ± 22.04 at 12 months and 90.83 ± 18.41 at 24 months. Complete root coverage was 81% (13 out of 16) at 6 and 12 months. At 24 months, complete root coverage was 75% (9 out of 12). The plaque and gingival indexes did not vary significantly between baseline and measurement times. Probing depth was maintained at healthy levels during the months of follow-up. Sensitivity decreased at 12 months (4 of 16) compared to baseline (14 of 16), and was maintained at 2 years (2 of 12). This retrospective study showed that acellular dermal matrix allograft could be considered a useful alternative for the treatment of single gingival recessions, reducing the discomfort and morbidity associated with the palatal donor site.

Single gingival recession associated with non-carious cervical lesion treated by partial restoration and coronally advanced flap with or without xenogenous collagen matrix: A randomized clinical trial evaluating the coverage procedures and restorative protocol.

Evaluate the use of collagen matrix (CM) as adjunctive to coronally advanced flap (CAF versus CAF + CM) to treat gingival recession (GR) associated with non-carious cervical lesion-combined defects (CDs). Sixty-two patients presenting 62 CDs (RT1 GR and non-carious cervical lesion (NCCLs) were randomly allocated to either CAF group (n=31): partial restoration of the NCCL and CAF; or to CAF + CM group (n=31): partial restoration of the NCCL and CAF associated with CM. Clinical, esthetic, patient-centered outcomes, and restorative parameters were assessed. After 12 months, CD coverage were 55.2% for CAF and 54.4% for CAF + CM (P=0.8). Recession reduction were 1.9 ± 0.8mm for CAF and 2.0 ± 0.7mm for CAF + CM (P=0.6). CAF+CM resulted in higher increase in keratinized tissue (KT) width (CAF: 0.3 ± 0.7mm; CAF + CM: 0.9 ± 0.8mm; P=0.004) and KT thickness gain (CAF: 0.1 ± 0.3mm; CAF + CM: 0.7 ± 0.2mm; P=0.001). Both treatments presented low postoperative pain and resulted in esthetics improvements. In addition, no restoration was lost, 27.4% showed a reduction of the superficial polishing, and 8% showed marginal staining, but still clinically acceptable. Partial resin composite restoration (with the apical limit up to 1mm of the estimated CEJ) and CAF alone or combined with CM are suitable for treating CDs. The use of CM provided additional benefits in terms of KT width and thickness gain. (NCT03341598).

Vertically Coronally Advanced Flap (V-CAF) to Increase Vestibule Depth in Mandibular Incisors.

Treatment of gingival recessions affecting mandibular incisors is scarcely documented. Despite a shallow vestibule depth being considered a poor anatomical condition, it has never been measured nor deemed a clinical parameter affecting the outcome of root coverage procedures. This study describes a vertically and coronally advanced flap (V-CAF) + connective tissue graft (CTG) technique to obtain root coverage and increased vestibule depth in the treatment of gingival recessions affecting mandibular incisors. Twenty patients with single gingival recessions were treated. The results showed that V-CAF+CTG is effective in increasing residual vestibule depth and in reducing recession depth. Immediately after surgery, a vestibule-depth increase of 5.9 ± 1.2 mm was reported, which was statistically significant compared to baseline, and it remained stable after 12 months (4.8 ± 1.1 mm). The mean percentage of root coverage was 98.3% ± 5.2% for all treated recessions, and complete root coverage (CRC) was achieved in 90% of cases (18 of 20). V-CAF+CTG could be considered a successful technique in terms of vestibule depth increase and CRC for the treatment of single gingival recessions in the mandibular incisors.

Coronally advanced flap achieved higher esthetic outcomes without a connective tissue graft for the treatment of single gingival recessions: a 4-year randomized clinical trial.

Limited long-term data are available when comparing the esthetic outcomes of coronally advanced flap (CAF) with or without a connective tissue graft (CTG). The aim of this study was to compare the 4-year esthetic outcomes of CAF vs CAF + CTG for the treatment of isolated maxillary gingival recessions. Forty-eight patients were randomly assigned for treatment either with CAF (control; N = 24) or to CAF + CTG (test group; N = 24). Patients were followed after the surgery until the final evaluation. A professional esthetic evaluation was performed using the Root coverage Esthetic Score (RES). Recession reduction, mean root coverage, and complete root coverage were also evaluated. Forty-two patients completed the study at the 4-year recall. A significant recession reduction was evident at 4 years, without significant intergroup differences. The CAF group showed a statistically significant higher final RES compared with the CAF + CTG group (9.14 ± 1.08 vs 7.25 ± 1.29, respectively, p < 0.001). Regarding the individual components of RES, gingival margin and marginal tissue contour were significantly higher in the CAF group compared with that in the CAF + CTG group. CAF presented with a significantly higher overall esthetic score than CAF + CTG, and in the individual RES components of marginal tissue contour and gingival margin after 4 years. CAF without the addition of CTG provided higher esthetic outcomes for the treatment of isolated gingival recessions.
