  • Marginal tissue recession makes problems like esthetics, root caries, hypersensitivity and plaque accumulation. Request for root coverage is higer than ever, especially esthetic problems involved. So techniques for root coverage hav been developed. There are some kinds of surgical techniques using soft tissue for root coverage. For example, free gingival graft, kinds of pedicle flap, subepithelial connective tissue graft(SCTG), and so on. Subepithelial connective tissue graft has many advantage for root coverage, that is less pain on donor site, good blood supply for graft, and more esthetic result. For this reaseon, this case report was performed to evaluate the effect of root coverage using subepithelial connective tissue graft. Three patients has Miller's class I marginal tissue recession and one patients has Miller's class III marginal tissue recession. The following period is 36.5 month on average. The results are as follows: 1. Root coverage of 100% was obtained in 5 of 6 defects, and 80% was obtained in 1 of 6 defects, The mean root coverage was 96,6% in six cases on 4 patients. 2. The mean root coverage was 3.83mm and mean recession depth decreased from 4mm to 0.16mm. 3. The mean width of clinical attached gingiva increased from 1.5mm to 4mm. The mean width of gained attached gingiva after surgery was 2.5mm. 4. The mean follow up period was 36.5 months. The longest follow up period was 50 months and the shortest follow up period was 22 months. 5. The result that obtained by surgery was stable during follow up period. Within the above results, root coverage with SCTG is an effective procedure to cover marginal tissue recession defect with long term stability.

  • Root coverage can be an efficacious treatment not only in aspect of dental symptoms like root caries and hypersensitivity, but also in aspect of esthetic problem. There are several predictable methods for gaining a connective tissue attachment to an exposed root surface. Among them, this case report will deal with three cases using enamel matrix derivative and connective tissue graft to recover esthetic and physiological periodontal environment and its form. This case report deals with three patients with gingival recession which has occurred by different causes. They were treated with de-epithelialized graft accompanied by application of enamel matrix derivative. 6-12 months later, all three patients showed considerable root coverage and clinically stable condition of healing. In conclusion, within the limitation of this study, de-epithelialized connective tissue graft accompanied by application of enamel matrix derivative shows stable and clinical acceptable results in aspect of root coverage.

  • Patients, who have gingival recession and complain of root sensitivity, or esthetic concerns, are candidates for root coverage. When free gingival grafting is used for complete root corverage, the results may not be entirely predictible unless the recession is shallow and narrow because a free gingival graft depends on collateral circulation from the lateral and apical parts of the recipient bed to survive over the avascular root. Various pedicle graft techniques can produce more esthetic results, but these procedures are only indicated when adequate donor tissues are available adjacent to the defect. This case report presents three cases for root coverage using the various connective tissue graft techniques. In the first case(Class III & IV), subepithelial connective tissue grafting was done and resulted in gingival coverage on the two-thirds of exposed root surface and blended with the adjacent tissue in color and texture. In the second case(Class I), connective tissue and partial thickness double pedicle graft resulted in complete coverage of denuded root surface. In the third case(Class I), recession was treated by supraperiosteal envelope technique. The root surface was covered completely and esthetically. Finally, the esthetics in both colors and tissue contours were acceptable to patients in all cases by the connective tissue grafting. However, in the case of the reduced interdental bone, the denuded root surfaces were hardly covered completely.

  • Purpose: One of the main objectives of periodontal reconstructive surgery is the coverage of exposed roots that occur due to gingival recession. and Aestheic concerns are usually the reason to perform root coverage procedure. This case report was performed to evaluate the effect of root coverage using subepithelial connective tissue graft(SCTG) on Miller's Class I marginal tissue recession. Materials and Methods: One patient, with two Miller's class I marginal tissue recession on both maxiallay canines, was treated with root coverage using SCTG (modified Nelson's technique). At baseline, the following measurements were recorded: 1) recession depth; 2) width of keratinized giniga. At 9, 10 months post-surgery, all clinical measurements were repeated. Result: 1) The mean root coverage from baseline to 9, 10 months post-surgery was 92.3%. 2) The mean recession depth decreased from 6.5 mm to 0.5 mm. 3) The mean width of keratinized gingiva increased from 1.25 mm to 3.5 mm. Conclusion: Within the above results, root coverage using SCTG is an effective procedure to cover Miller's class I marginal tissue recession defect. Also, patient with aesthetic concern could be satisfied with this result.

  • Exposed root surfaces can cause esthetic problems, hypersensitivity, and root caries. Numerous efforts have been tried to cover the recessed root surfaces, and various techniques have been developed and introduced. Among these, subepithelial connective tissue graft which shows high coverage rate in various researches, has the advantage of good color match, less discomfort to the donor site, rich vascularity, and high predictability. Following results were obtained after investigating 6 and 18 months post operatively, 98 cases of subepithelial connective tissue graft from 48 patients who underwent subepithelial connective tissue graft procedure in the department of periodontology, college of dentistry, Yonsei university. 1. The total average root coverage of Miller class I, II & III were 76.2?24% at 6 months follow-up and 75?25.2% at 18 months follow-up with no statistically significant difference between the follow-up periods.(p<0.05) 2. The percentage of teeth showing complete coverage were 41.9% at 6 months follow-up and 39.2% at 18 months follow-up. 3. At 6 months follow-up, Miller classification I showed 84.9?20.7%, class II showed 82.5?17.7%, and class III showed 62.3?24.5% of coverage. In class III recession, statistically significantly less root coverage was observed compared to class I & II. (p(0.05) 4. At 18 months follow-up, Miller classification I showed 92.2?13.5%, class II showed 84.3?17.4%, and class III showed 59.5?24.5% of coverage. In class III recession, statistically significantly less root coverage was observed compared to class I & II. (p<0.05) In conclusion, subepithelial connective tissue graft for class I and II recession can be used as a clinically predictable treatment modality for root coverage.

  • 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.

  • In dental esthetics, soft tissue plays an important part, probably very large portion of it. A clear understanding of the periodontal tissues and its management around teeth and implants help us to develop concepts for a modern dental treatment that addresses the needs of demanding patients in regard of esthetics and durability. When we talk about esthetic, we can say that one of the most important element is a harmonization with gingiva (soft tissue) called 'Pink Esthetic' As for the pink esthetics, gingival line(contour) takes most of the influence on esthetic result; it consists of labial gingival level, interproximal papilla height, and a line that connects them. In the gingival recession, labial gingival level and gingival contour move to the apical portion, and the root area is exposed. It leads to the unesthetic result. Root coverage technique is classically used to treat gingival recession (marginal tissue recession) of natural teeth. It is an essential technique on periodontal plastic surgery part. It is also a very useful technique to recover soft tissue problems in implant dentistry. So, root coverage technique must be mastered for a good implant esthetic result. The general overview of root coverage procedures will be discussed with step by step explanation to get more esthetic result.

  • Purpose: The subepithelial connective tissue graft(SCTG) has been proven to be a highly predictable treatment modality for coverage of gingival recession. This case report was performed to evaluate the effect of various root coverage procedures using SCTG on gingival recession. Materials and Methods: Three patients presents with Miller's class I recession defect on the maxillary canine. Each other SCTG(coronally advanced flap, Bruno's Tech., envelope Tech.) were performed for root coverage. Clinical parameters assessed included recession depth, recession width, and keratinized gingival width. Measurements were taken at baseline and 2 months and follow up end. Results: The average of root coverage was 4 mm(100% of the pre-operative recession depth) at the 2, 5 months examination. The average increase of keratinized tissue between the baseline and the 2 months amounted to 3.2mm. Conclusion: Within the above results, various root coverage using SCTG is an effective procedure to Miller's class I recession defect and patient could be satisfied aesthetic requirement.

  • Purpose: The integrity of interproximal hard/soft tissue has been widely accepted as the key determinant for success or degree of root coverage following the connective tissue graft. However, we reason that the gingival biotype of an individual, defined as the distance from the interproximal papilla to gingiva margin, may be the key determinant that influence the extent of root coverage regardless of traditional classification of gingival recession. Hence, the present study was performed with an aim to verify that individual gingival scalloping pattern inherent from biotype influence the level of gingival margin following the connective tissue graft for root coverage. Methods: Test group consisted of 43 single-rooted teeth from 21 patients (5 male and 16 female patients, mean age: 36.6 years) with varying degrees of gingival recession requiring connective tissue graft; 20 teeth of Miller class I and 23 teeth of Miller class III gingival recession, respectively. The control group consisted of contralateral teeth which did not demonstrate apparent gingival recession, and thus not requiring root coverage. For a biotype determination, an imaginary line connecting two adjacent papillae of a test tooth was drawn. The distance from this line to gingival margin at mid-buccal point and this distance (P-M distance) was designated as "gingival biotype" for a given individual. The distance was measured at baseline and 3 to 6 months examinations postoperatively both in test and control groups. The differences in the distance between Miller class I and III were subject to statistical analysis by using Student.s t-test while those between the test and control groups within a given patient were by using paired t-test. Results: The P-M distance at 3 to 6 months postoperatively was not significantly different between Miller class I and Miller class III. It was not significantly different between the test and control group in a given patient, either, both in Miller class I and III. Conclusions: The amount of root coverage following the connective tissue graft was not dependent on Miller's classification, but rather was dependent on P-M distance, strongly implying that the gingival biotype of a given patient may play a critical impact on the level of gingival margin following connective tissue graft.
