ABSTRACT
La recesión gingival es considerada como una deformidad o condición mucogingival, la Academia Americana de Periodontología, define a la recesión gingival como el desplazamiento del margen del tejido blando apical a la unión cemento-esmalte con la exposición de la superficie radicular. El tratamiento de las recesiones gingivales es un motivo de consulta común debido a razones estéticas, hipersensibilidad dentinaria, molestias durante el cepillado e incluso temor a la pérdida dentaria. Es una situación clínica común, 60% de la población humana tiene algún tipo de recesión gingival. Al realizar el examen clínico a paciente masculino de 55 años, se observó una recesión gingival tipo 1 (RT1) sin pérdida de inserción interproximal de la clasificación de Cairo. Se realizó el colgajo posicionado coronalmente (CPC) utilizando una matriz dérmica acelular (MDA) de origen humano OrACELL®. Se obtuvo resultado favorable en el recubrimiento de recesiones gingivales múltiples; considerándolos como una buena alternativa frente a los injertos gingivales autógenos. Concluyendo que, el uso de la matriz dérmica acelular para el tratamiento de la recesión gingival tipo 1 es una adecuada opción para el recubrimiento radicular. Se recomiendan más estudios a largo plazo para ver la estabilidad de los resultados obtenidos con la MDA (AU)
Gingival recession, considered a deformity or mucogingival condition, the American Academy of Periodontology, defines gingival recession as the exposure of the root surface resulting from migration of the gingival margin apical to the cementoenamel junction (CEJ). The treatment of gingival recessions is a common reason for consultation due to aesthetic reasons, dentin hypersensitivity, discomfort during brushing and even fear of tooth loss. It is a common clinical situation, 60% of the human population has some kind of gingival recession. Clinical examination of a 55-year-old male patient showed a type 1 gingival recession (RT1) without loss of interproximal insertion of the Cairo classification. Coronally advanced flap (CAF) was performed using an acellular dermal matrix (ADM) of human origin OrACELL®. Favorable results were obtained in the coating of multiple gingival recessions; considering them as a good alternative to autogenous gingival grafts. Concluding that, the use of the acellular dermal matrix for the treatment of gingival recession type 1, is a suitable option for root lining. Further long-term studies are recommended to see the elasticity of MDA outcomes (AU)

OBJECTIVES@#This study aimed to evaluate the efficacy and long-term stability of tunnel technique (TUN) and coronally advanced flap (CAF) combined with connective tissue graft (CTG) in treating gingival recession.@*METHODS@#Databases including PubMed, Web of Science, Embase, and CNKI were electronically searched to collect randomized controlled trial (RCT) of CAF+CTG compared to TUN+CTG in the treatment of Miller class Ⅰ or Ⅱ gingival recession on September 1, 2022.@*RESULTS@#There were 8 RCTs with 305 patients (454 recession sites) participating. The results of the Meta-analysis revealed that, in terms of mean root coverage (MRC) of main indicators, no significant difference was found between the CAF group and the TUN group in both short- and long-term results, which were [MD: 1.45%, 95%CI (-2.93%, 5.82%), P=0.52] and [MD: -0.70%, 95%CI (-6.41%, 5.00%), P=0.81]. However, the CAF group outperformed the TUN group in the long term [MD: 5.69%, 95%CI (0.87%, 10.50%), P=0.02], and the results of complete root coverage (CRC) analysis were similar to those of MRC. In the short term, the TUN group grew keratinized gingiva significantly faster than the CAF group [MD: -0.38 mm, 95%CI (-0.67 mm, -0.10 mm), P=0.008]. Long-term findings revealed no significant difference between the two groups [MD: -0.26 mm, 95%CI (-0.94 mm, 0.43 mm), P=0.46]. The TUN group's secondary index root coverage esthetic score (RES) was statistically significantly higher than the CAF group's [MD: 0.62, 95%CI (0.28, 0.96), P=0.000 3]. Given that there were few results included in the literature and the heterogeneity was too great, no significant difference was observed in the postoperative VAS pain index score [MD: 0.53, 95%CI (-1.96, 3.03), P=0.68].@*CONCLUSIONS@#This study discovered that both CAF+CTG and TUN+CTG can achieve good root coverage in treating gingival recession, with CAF outperforming TUN and both groups achie-ving good long-term stability. After the operation, the TUN group had a higher RES than the CAF group. Given the limitations of this study, more high-quality studies are needed in the future to demonstrate the efficacy of TUN in gingival retraction surgery.

@#Gingival recessions (GRs) result in root hypersensitivity, root surface caries, and esthetic problems. Various root coverage surgeries are being developed for periodontal plastic therapy. The tunnel technique (TUN) is one of the most widely applied surgeries due to its features of being minimally invasive, practical, excellent outcomes and long-term stability; however, there are still some limitations of this technique. The history and evolution from the envelope flap to TUN, including its efficiency when compared with coronally advanced flaps with a connective tissue graft (CTG), are reviewed in this paper. The limitations of TUN are discussed in consideration of our clinical experience; for example, there is high technique sensitivity when TUN is applied in GR>5 mm because of the great difficulty in covering the grafts. The advantages of surgical access, including vertical incisions in the vestibule, “W” type and pinhole access, are discussed for different situations. Mattress sutures and sling sutures in a single tooth or multiple teeth are applied in TUN. The different types of grafts, such as CTG, platelet-rich plasma, articular dermal matrix and xenogeneic collagen matrix, are described. Mechanical, chemical and biological conditioning of the root surface are recommended during surgery. Protecting the surgical area and taking antibiotics postoperatively are also very important. Finally, the modifications when TUN is applied with other kinds of techniques are discussed, including lateral closed TUN, laterally positioned flaps, double papilla flaps and frenuloplasty. Minimally invasive, esthetic, long-term stability and simplified techniques are the development trends of TUN in the future.
ABSTRACT
Background:This case report describes treatment of multiple gingival recession with subgingival connective tissue graft and coronally advanced flap technique in treatment of maxillary teeth. Material And Methods:Connective tissue grafting wasdone in relation to upper right second premolar, first premolar, canine, right central incisor, left central incisor and left lateral incisor (#15,#14,#13,#11,#21,#22). A split thickness flap was elevated without disturbing periosteum in this region. The area between canine and second premolar was selected to harvest the graft. The graft was placed on the recipient bed and suturing was done. Result:Predictable root surface coverage could be obtained with use of coronally advanced flap and subepithelial connective tissue graft. Conclusion:Subepithelial connective tissue graft along with coronally advanced flap still stand as a gold standard treatment for gingival recession coverage.
ABSTRACT
Gingival Recession is a common, complex, and unpleasant clinical condition. It is more commonly associated with root hypersensitivity, impaired esthetics and root caries. Successful treatment outcome becomes challenging in such cases. Coronally advanced flap for rootcoverage is most commonly used technique. Combination of biological membranes derived from human body itself along with coronally advanced flap yields better results. This case report describe s a case of bilateral Class I gingival recession treated with amniotic membrane on one sideand PRF membrane along with Coronally advanced flap on other side.
ABSTRACT
l procedimiento de cobertura radicular para tratar recesiones gingivales es el tratamiento ideal según la literatura actualizada, siendo más utilizado el colgajo de avance coronal con diferentes resultados clínicos y estéticos que ponen en duda si realizar este procedimiento sumando a un injerto de tejido conectivo se van a obtener resultados más predecibles y más estéticos en cuanto a la eliminación del defecto. En este reporte un paciente de 24 años de edad, masculino, refiere hipersensibilidad y disconformidad estética en la zona de la recesión gingival. En este caso se utilizará el cubrimiento radicular con colgajo de avance coronal más injerto de tejido conectivo autólogo.

he root coverage procedure to treat gingival recessions is the best line of treatment, being the most used the coronal advanced flap. There have been multiple clinical and aesthetic results that cast doubt on whether this procedure by adding a connective tissue graft will be a more predictable and more aesthetic regarding defect removal. In this case report a patient 24-year-old male refers hypersensitivity and aesthetic discomfort in the area of gingival recession. An autologous graft with a coronal flap advancement of connective tissue will be used. After six months of healing the patient reports improvements in: sensitivity, plaque control and aesthetics.
ABSTRACT
Objective · To observe the clinical outcomes of a modified laterally moved and coronally advanced flap combined with a connective tissue graft (CTG) for the treatment of severe Miller class Ⅱ or class Ⅲ isolated recession defects. Methods · Three patients with initial defect depths of more than 5 mm and malposition in some teeth were enrolled and underwent a modified laterally moved and coronally advanced flap combined with CTG. Recession depth (RD), keratinized tissue height (KTH) of both donor and adopted site, pocket depth (PD), and clinical attachment loss (CAL) at baseline and follow-up one-year after treatment were documented. Root coverage rate (RC) was calculated and visual analogue scale (VAS) was used to evaluate patient's satisfaction degree. Results · The mean RDs at baseline and followup were (5.3±0.5) mm and (0.3±0.5) mm. The mean RC at follow-up was (93.3±9.4)% and two cases had complete root coverage. The KTHs at adopted and donor sites were (0.3±0.5) mm and (6.0±0.8) mm at baseline and (4.3±0.5) mm and (5.7±1.3) mm at follow-up, respectively. PD and CAL were decreased from (1.7±0.5) mm and (7.0±0.8) mm at baseline to (1.3±0.5) mm and (1.3±1.2) mm at follow-up, respectively. The VAS value was 9.0±0.8 and subjective evaluation of patients was improved significantly at one-year follow-up, including root sensitivity and aesthetics. Conclusion · The modified laterally moved and coronally advanced flap with CTG has ideal clinical outcomes and satisfaction degree for the treatment of patients with severe recession defects that lack keratinized tissue and combine with buccal malposition.
ABSTRACT
Background: Gingival recession (GR) is one of the most common esthetic and functional concerns associated with periodontal disease. A variety of surgical procedures has been introduced to the field of cosmetic periodontology for the treatment of GR. Aim: To evaluate and compare the clinical outcome of semilunar coronally advanced flap (SCAF) with and without button technique in the treatment of Miller’s Class I and II GRs. Study Design: A total of 12 subjects with bilateral single Miller’s Class I and II recession were selected for the study. Split mouth design was used. Materials and Methods: Surgical sites were randomly divided into test and control groups. In control sites, SCAF alone was done whereas in test site, a combination of SCAF and button technique was performed. The clinical parameters including GR, periodontal pocket depth, clinical attachment level (CAL), and width of keratinized gingiva were recorded at baseline and 6 months postsurgery. Data so collected were put to statistical analysis. Statistical Analysis: Student’s t‑test was used to find significance of parameters between baseline and 6 months. For inter‑group comparisons paired t‑test was performed. Results: Statistically significant improvements were recorded in both groups from baseline to 6 months. Inter‑group comparison yielded statistically significant differences in GR and CAL in favor of test group. Conclusion: Combination of SCAF and button technique resulted in statistically significant improvements in clinical parameters as compared to SCAF alone. Future clinical studies with much larger sample size and longer follow‑up periods are warranted.
ABSTRACT
Las recesiones gingivales son un hallazgo clínico muy frecuente que ocasionan problemas estéticos, hipersensibilidad dentaria y dificultad para llevar a cabo una correcta higiene oral en los pacientes. Uno de los objetivos de la terapia periodontal es corregir quirúrgicamente las recesiones; se han descrito una variedad de enfoques quirúrgicos como métodos efectivos para cubrir las superficies radiculares expuestas, siendo el injerto libre de tejido conectivo una de las técnicas que hoy en día ofrece un buen porcentaje de éxito y predecibilidad. Se presenta el caso de un paciente con retracción del margen gingival en el maxilar superior derecho; se describe el procedimiento quirúrgico usando una técnica bilaminar empleando un injerto subepitelial de tejido conectivo bajo un colgajo de espesor parcial posicionado coronalmente, y se obtienen buenos resultados estéticos y cobertura radicular.
Gingival recession is a very often clinic complaint which frecuently cause esthetic problems, hypersensibility and inadecuate oral hygiene to patients. One of the objetives of periodontal therapy is to correct gingival recession, for their treatment some techniques of mucogingival surgery have been designed, being the connective tissue graft, so far, one that offers good percentage of success as well as great predictibility. This clinical report describes a patient with gingival recession on the maxillar right side. A radicular covering using a bilaminar technique with a subepithelial connective tissue graft combined with a coronally advanced flap is used in order to solve the case providing good aesthetic results and root coverage.
ABSTRACT
Background: Coverage of gingival recession defects has been considered as a subject of interest for dental practitioners. Aim: The present study was aimed to compare the clinical outcomes of root coverage (RC) procedures, using coronally advanced flap (CAF) in combination with acellular dermal matrix (ADM) with or without enamel matrix derivatives (EMD). Materials and Methods: A total of 36 Miller class I or II recession defects in 15 eligible patients were selected. The defects were randomly allocated to test (CAF+ADM+EMD) and control (CAF+ADM) groups. Recession depth (RD), recession width (RW), width of keratinized tissue (WKT), clinical attachment level (CAL), and the position of mucogingival junction (MGJ) were measured at baseline, two and six months after treatment. Statistical Analysis: Data were analyzed using repeated measures ANOVA and paired sample t-test with the patients as statistical unit. Results: At two-month follow-up, the mean RC for CAF+ADM+EMD and CAF+ADM was 82.75 ± 22 and 88.89 ± 22 percent, respectively. However, these values did not change significantly after six months. Both treatments led to significant RC (P < 0.001), whereas no significant differences were observed in WKT, CAL, and MGJ between the study groups. Conclusion: The application of EMD does not improve the clinical efficacy of ADM in combination with CAF in RC procedures.

PURPOSE: The treatment of gingival recessions is needed to reduce root sensitivity and improve esthetical satisfaction. Several surgical techniques have been proposed to achieve these goals. The use of connective tissue grafts has made esthetic root coverage a predictable procedure. Numerous clinical studies have represented that using connective tissue grafts to cover exposed root surface showed high success rates. This is a case report which demonstrates the technique to obtain root coverage of a buccal recession defect. MATERIALS AND METHODS: A 35-year-old patient with a high level of oral hygiene was selected for the study. This patient had one Class I Miller recession defect in the mandible. A coronally advanced flap in combination with the connective tissue graft was chosen for the treatment. After surgery, the patient was told to visit the hospital once a week for his oral management and professional prophylaxis. The depth of initial recession was 4.0 mm. RESULT: After three months, it reduced to 0.0 mm, and the average recession reduction was 4.0 mm. The average root coverage was 100%. CONCLUSION: The connective tissue graft is both effective and predictable way to produce root coverage in increasing the width of CAL and KT of various adjacent gingival recessions.

O objetivo do presente trabalho foi avaliar clinicamente, o enxerto de tecido conjuntivo subepitelial (CO), o Alloderm® (ALL) e o retalho reposicionado coronariamente (RPC) quando utilizados no tratamento da recessão gengival tipo classe I de Miller. Trinta pacientes participaram do estudo. Os pacientes foram distribuídos em três grupos de 10 pacientes. Dez pacientes com idade média de 38.7(±10.3) anos foram tratados pela técnica do RPC, incluindo 18 recessões. Dez pacientes com idade média de 40.2(+/-9.9) anos foram tratados pela técnica do CO, totalizando 23 recessões. Dez pacientes com idade média de 37.7(±11.2) anos foram tratados através da utilização do ALL, totalizando 18 recessões. Os pacientes não poderiam apresentar cárie sobre a superfície radicular exposta, a junção amelocementária deveria ser visível e identificável, não poderia ter sido submetido a nenhum tipo de tratamento cirúrgico nos elementos envolvidos no experimento nos últimos 24 meses e não apresentar bolsa periodontal ou tratamento endodôntico nos elementos dentários candidatos à cobertura das superfícies radiculares expostas. As seguintes mensurações foram realizadas: índice de placa (IP), índice gengival (IG), profundidade de bolsa à sondagem (PBS), nível de inserção à sondagem (NIS), largura de gengiva ceratinizada (GI), profundidade da recessão gengival (PRG), posição da linha muco-gengival (PLMG). As medidas de IP, IG, PBS, NIS, GI, PRG e PLMG, foram executadas com sonda periodontal calibrada nos dias 0, 30, 60, 90, 120 e 180, exceto PBS e NIS que não foram mensuradas no dia 30. Avaliações subjetivas relativas ao resultado estético alcançado foram realizadas pelo operador e pelo paciente no sexto mês pós-operatório. O teste T de Student para amostras pareadas foi utilizado nas análises intragrupos e o ANOVA foi utilizado nas análises entre os grupos (p<0.05). Os resultados mostraram uma cobertura radicular média de 66.8% para o grupo RPC, enquanto a cobertura radicular média dos grupos ALL e CO foi de 75.9% e de 87.9%, respectivamente. Não houve diferença estatisticamente significante entre os valores de cobertura radicular média entre os grupos ALL e CO. Os valores para o grupo CO eram significantemente maiores que o do grupo RPC. Os valores médios de ganho de inserção clínica de 4.2(±0.9) mm e de 3.5(±1.0) mm dos grupos CO e ALL, respectivamente, foram significantemente maiores que os valores de 2.1(±0.7) mm do grupo RPC. O aumento médio de largura de gengiva ceratinizada foi de 1.41(±0.3) mm no grupo CO e de 1.3(±0.2) mm no grupo ALL, não havendo diferença significativa entre os dois grupos. Não houve alteração na largura de gengiva ceratinizada no grupo RPC. Concluindo, as técnicas de CO e ALL apresentaram resultados clínicos semelhantes e superiores ao RPC em relação ao ganho de inserção clínica, aumento na largura de gengiva ceratinizada e cobertura radicular
The aim of the present study was to clinically evaluate the subepithelial connective tissue graft (CTG), Alloderm (ALL) and coronally advanced flap (CAF) in the treatment of gingival recessions Class I of Miller. 30 patients were included in the study, and were divided in 3 groups of 10 patients. 10 patients with mean age of 38.7 (± 10,3) years were treated with CAF, including 18 defects. 10 patients with mean age of 40.2(± 9.9) years were treated with CTG, including 23 defects, while 10 patients with mean age of 37.7(±11.2) were treated with ALL, including 18 gingival recessions. The patients should not have caries over the denuded root surface, the cementoename junction should visible and easily identified, should not have received any surgical treatment during the last 24 months, and not have periodontal pockets or endodontic treatment at the tested teeth. The following measurements were performed: Plaque index (PI), gingival index (GI), probing pocket depth (PPD), probing attachment level (PAL), width of keratinized gingiva (KG), depth of gingival recession (GR) and position of the mucogingival junction (MGJ). PI, GI, PPD, PAL, KG, GR, MGJ were made with a calibrated periodontal probe on days 0, 30, 60, 90, 120 and 180. PPD and PAL were not measured on day 30. Subjective evaluations were performed by the patient and the dentist on day 180. Paired T Test was used to observe differences within the groups in the different time periods, and ANOVA was performed to analyze differences between the 3 surgical procedures (p<0.05). The results showed that the mean root coverage was 66.8% for the CAF group, while the corresponding values for ALL and CTG were 775.9% and 81.4%, respectively. There was no significant difference between the values of ALL and CO, but the mean values for root coverage of CO group were statistically higher than the CAF group. The mean values of clinical attachment gain of 4.2 (± 0.9) mm and 3.5 (± 1.0) mm in CTG and ALL groups, respectively, were statistically higher than the corresponding values for CAF group (2.1 ± 0.7 mm). There was no significant difference between the mean increase of KG of 1.4 (± 0.3) mm in CTG group and 1.3(± 0.2) mm in ALL group. KG was not different in the CAF group. In conclusion, CTG and ALL procedures presented similar and better results than CAF procedure in relation to clinical attachment gain, increase in the width of KG and the % of root coverage
