Filter by:Gingival recession is defined as the displacement of the soft tissue margin apical to the cemento-enamel junction with exposure of the root surface. It affects a broad population with presence of periodontal disease as well as periodontally healthy individuals. The occurrence of gingival recessions is age-dependent and their development begins relatively early in life. For instance, gingival recessions were noticed in more than 60% of Norwegian 20-year-olds and in more than 90% of the older population. Similar findings were reported in Brazilian and French population. In populations deprived of dental care, the occurrence of gingival recessions was even higher. Many factors have been implicated in the etiology of gingival recession, including plaque, position of the tooth in the arch and improper toothbrushing. It is difficult to see a single cause for the development of labial gingival recession. It has been demonstrated in several investigations that if left untreated, the probability of progression of the recession is high even with good oral hygiene. The indications for treatment of gingival recession are: esthetics, dental hypersensitivity, and the prevention of caries as well as further progression of the recession. Therapeutic options for recessions have been well documented with a high degree of success. Their ultimate goal is the location of the gingival margin coronal to the CEJ, with minimal probing depth and a pleasant soft tissue integration with the adjacent teeth. With such a prevalent condition, it becomes critical to discriminate when to treat these lesions and which are the anatomical and surgical characteristics that are going to determine the amount of root coverage. Regarding surgical characteristics, it has been demonstrated that the accomplishment of complete root coverage may be prejudiced by the post-surgical position of the gingival margin (the more coronal to the CEJ the greater the chance to achieve root coverage). The same author conducted a randomized clinical trial showing that the higher the flap tension, the lower the recession reduction. Another surgical factor affecting root coverage may be the use of microsurgical approaches by the use of smaller diameter sutures. According to a recently published systematic review, early suture removal (less than 10 days) can negatively affect root coverage outcome. The healing process after pedicle graft was investigated in an animal model study. The healing was divided into four different stages, the adaption stage (0-4 days), the proliferation stage (4-21 days), the attachment stage (27-28 days) and the maturation stage (1-6 months). During the proliferation stage, connective tissue invades the fibrin layer from the basal level of the flap, and after 6-10 days a layer of fibroblasts is seen in apposition to the root surface. These cells are believed to differentiate into cementoblasts at a later stage of healing. At the end of the proliferation stage, thin collagen fibers are formed adjacent to the root surface, but a fibrous union between the connective tissue and the root has not been observed. It seems logical that stabilizing the flap with sutures for a prolonged period of time during the proliferation phase would help maintain the gingival margin on a more coronal position postoperatively. On the other hand, the longer the sutures remain postoperatively, the greater the chances of plaque accumulation and inflammation affecting negatively to root coverage. The systematic review by Tatakis and Chambrone included 17 randomized clinical trials that provided an overall data of 325 single recession defects that were treated by coronally advanced flap. While they investigated time of suture removal, the studies included in this study did not account for this variable, thus leading to some bias. Moreover, different suture materials, type of suturing technique may also play an important role in the healing process. Therefore, the aim of this study is to evaluate the clinical outcome of timing suture removal regarding root coverage on coronally advanced flap.
A total of 24 healthy non-smoker patients requiring FGG recruited for the study. Subjects were equally and randomly assigned into two groups. Test group, local application of HYADENT BG on both donor and recipient sites. Control group, application of normal saline on both sites as placebo. The FGG dimensions were evaluated at 1, 3- and 6-month recall using digital photographs. Post-operative pain was evaluated for 14 days. Color matching and patient satisfaction were evaluated at 6 months.
Introduction: Gingival recession is a lesion characterized by the loss of attachment of root surface of the tooth, resulting in an apical migration of the gingival margin that occasionally generates aesthetic problems, hypersensitivity and difficulty in maintaining proper hygiene. Several anatomical factors have been associated both with the incidence and progression of gingival recession and with the prognosis of the surgical treatments proposed for its correction. These factors include the absence of keratinized tissue, the gingival phenotype, root prominence and shallow vesrtibular depth. Objectives: The objective of the study is to evaluate, through a series of prospective cases, the influence of each of the anatomical factors on the success of root coverage. Methods: 20 patients with gingival recession defects will be treated with CAF+CTG using various autogenous gingival graft. Three-dimensional analysis of superimposed preoperative and postoperative images will be performed. Linear and surface root coverage will be calculated and correlated to various anatomical parameters such as vestibular depth and root prominence. A multilevel statistical analysis will be conducted, adjusting for the correlation among multiple observations.
OrACell has been tested as a barrier in bone regenerative procedures showing promising results in new bone formation after socket preservation, but no data is available on root coverage procedures. Moreover, it has been suggested that keratinized tissue width (KTW) ≥2mm and gingival thickness (GT) ≥1.2 mm at 6 months of the surgical procedures are two important predictors for long term stability of gingival margin Therefore, it was hypothesized that soft tissue thickness and keratinized tissue width may influence the percentage of root coverage. By means of a prospective case series (12 patients in total), the aim is to study the performance of the OrACell dermal matrix in the treatment of multiple and adjacent gingival recessions, determining the amount of complete root coverage obtained at 6 months of follow-up. At the same time, it is intended to evaluate the effect of initial gingival thickness, by means of digital scanning, upon the success of root coverage procedure with OrACell.
The aim of the present study is to evaluate, whether use of the modified free gingival graft (mod-FGG) technique improves treatment outcomes after surgical root coverage at mandibular incisors with gingival recession defects.
The purpose of the study is to compare the clinical effectiveness of gingival unit graft (GUG) and connective tissues graft (CTG) in Miller's class I and II gingival recession.
Prospective, randomized, within subjects-controlled design
The purpose of this study was to compare the effectiveness of microsurgical and macrosurgical approaches on CPFs plus SCTGs for the treatment of localized gingival recession defects (Miller class I or II) over the course of 6 months based on clinical periodontal parameters, periodontal phenotypes, and the postoperative complaints and satisfaction levels of the patients. We hypothesized that root coverage achieved through microsurgery in Miller I or II gingival recessions would improve clinical periodontal outcomes and the periodontal phenotype, with greater postoperative comfort and aesthetic satisfaction in comparison with conventional macrosurgical techniques. Miller Class I and II gingival recession defects, at least 3.0 mm deep, were selected and randomly assigned to receive micro or macrosurgical techniques. Both techniques were performed using a coronally positioned flap with a subepithelial connective tissue graft. Plaque and gingival indices, gingival recession depth and width, probing pocket depth, bleeding on probing, clinical attachment level, width of keratinized gingiva, aesthetic score and percentage of root coverage, postoperative complaints, and satisfaction of the participants completing the study were evaluated at follow-up 1st, 3rd and 6th months.
This randomized controlled clinical study aimed to evaluate the success of the combination of tunnel technique and concentrated growth factor membrane for root coverage in treating multiple gingival recessions and compare with the gold standard connective tissue graft.
Recession presents a day to day challenge due to the high esthetic demand of the patients. The prevalence, extent, and severity of recession associated with intra-bony defects due to periodontitis increases with age rendering the success of the root coverage procedures questionable due to loss of interdental papillary support. . Therefore, connective tissue graft wall technique in cases of Cairo's RT2 and RT3 gingival recession associated with intra bony defects seems promising with regard to recession depth reduction and radiographic bone fill.
