| Abstract|| |
The periosteum that covers the bone is highly composed of cellular connective tissue which is rich in vascularity with greater regenerative potential, thereby making it suitable to use as an autogenous graft material. This technique of periosteal eversion uses periosteum to cover the denuded root surface of multiple teeth prior to orthodontic treatment. Therefore, the purpose of the case series was to assess the amount of root coverage obtained with the help of eversion of periosteum where a single surgical site is involved in cases of periodontally compromised teeth that needs orthodontic correction. Patients with Miller's Class II/III were selected with malpositioned teeth. Partial thickness flap was elevated, and the periosteum was separated from the underlying bone surface. It is then everted to cover the exposed root surface and stabilized with vicryl suture. After 6 months of evaluation, periosteal eversion technique covered 75% of the denuded root surface. Hence, the periosteal eversion technique can be used as a preliminary procedure for the treatment of gingival recession that gives support for the tooth for further orthodontic treatment.

| Clinical Relevance to Interdisciplinary Dentistry|| |
This study indicates that, with simultaneous treatment of orthodontic correction and recession coverage with periosteum gives good results.
| Introduction|| |
Gingival recession is the migration of the marginal gingiva apical to the cementoenamel junction leaving the root surface exposed to the oral environment. The American Academy of Periodontology's 1996 position paper on mucogingival surgery stated that root coverage is indicated to increase esthetic demands, reduction of root sensitivity, management of root caries, or cervical abrasions. Various techniques have been described in the literature including subepithelial connective tissue graft and subpedicle connective tissue graft.,, However, the success of these cases is very limited due to various reasons such as donor site morbidity, requires second surgical site, technique sensitive, postoperative pain, and requires blood supply from both periosteum and bone as well. There are several predisposing factors that lead to gingival recession; such factors include bone dehiscence, thin gingival biotype, and malposition of the teeth. Gingival recession could occur as a result of trauma resulting from excessive or improper tooth brushing and any inflammatory reactions of the gingival leading to periodontitis. Malaligned teeth with class II/III recession require two-stage surgical procedure. At baseline, the parameters measured were clinical probing depth, recession depth, and width. All the parameters were evaluated at baseline and 3 months' and 6 months' interval after the surgery. Hence, this case series describes the recession coverage of multiple teeth with a periosteal eversion technique as a preliminary procedure.

Case report 1
A patient aged 23 years old has come to the Dental College and Hospital, Chennai, with a chief complaint of spacing and proclined anteriors in both upper and lower jaw. On clinical examination, class III gingival recession defected was diagnosed according to the classification given by Miller in 1985 in relation to 31.41 [Figure 1]a. Written informed concern was obtained from the patient detailing the procedure with the risks and benefits involved with it. The treatment planned with initiation of orthodontic procedure with simultaneous root coverage with decortication of the edentulous area.

The site of incision was anesthetized with 1:80,000 dilution of lignocaine hydrochloride. A partial thickness flap was elevated on the buccal surface from 32 to 42. The periosteum was scored at the base and is separated from the underlying bone. The periosteum was pushed to lingual side where full thickness flap was elevated [Figure 1]b. The edentulous site was decortisized and covered with particulate graft. Later, PRF was placed in the recession site and it was covered by the exposed periosteum and stabilized with vicryl 4-0 suture [Figure 1]c. The flap closed back with the same and coepak as periodontal dressing was given. The patient was instructed to refrain from mechanical plaque control measure for a period of 30 days and advised for chemical plaque control. The follow-up period was carried out at 1 month and at 6 months and the results were satisfactory [Figure 1]d.
Case report 2
A female patient aged 33 years old has come to the department with a chief complaint of spacing and proclination of her lower front teeth with receded gums from 32 to 42 [Figure 2]a. After thorough clinical examination, the treatment planned was orthodontic treatment along with recession coverage using periosteal eversion technique.

The exposed roots to be treated were thoroughly planned and a local anesthetic solution was given with 1:80,000 dilution of lignocaine hydrochloride with adrenaline. A partial thickness flap was elevated on both labial and buccal side from 33 to 43. The periosteum was scored at the base on the lingual side and whole of the periosteum was pushed to labial side [Figure 2]b. The edentulous area was decorticised and particulate graft (xenograft-osseograft) was placed. All the exposed root surfaces were covered with GTR (Guided Tissue Regeneration) membrane over which the periosteum was covered passively and sutured with 4-0 vicryl suture [Figure 2]c. The flap was closed back with silk suture. Clinical follow-up was performed at 1st and 6 months [Figure 2]d.
Case report 3
A female patient aged 29 years old has come to the hospital with a chief complaint of spacing and receding gums in her lower front tooth region. On clinical examination, the case was diagnosed to have Millers class II recession in respect to 31, 41 [Figure 3]a. The treatment planned was to correct the spacing with orthodontics and cover recession as well.

After anesthetizing the surgical site, a partial thickness flap has been raised from 32 to 42. The periosteum was scored on the lingual side and the periosteum separated from the underlying bone [Figure 3]b. Decortication of the edentulous area was done with simultaneous grafting (xenograft-osseograft) in that area. GTR was placed covering the recession over which the periosteum was covered and stabilized with vicryl 4-0 suture. The flap was closed with silk suture [Figure 3]c. Follow up was done at 1st and 6 months [Figure 3]d.
| Discussion|| |
The purpose of this case series was to describe the importance of recession coverage as a preliminary procedure prior to orthodontic treatment using periosteal eversion technique. The periosteum, an envelope covering the alveolar bone and the root surface was selected for root coverage procedure. Various benefits of using periosteum as a root coverage material were due to the presence of cumbersome properties of it such as its highly osteogenic, fibrogenic nature, it has both neuroproliferative and vasculoproliferative activity caused after surgical trauma., In addition, there was no need of second surgical site for graft procuring and thereby results in less morbidity and patient discomfort as well. Considering the cells present in the periosteum, it has diverse population of cells that include fibroblasts, fibroblast progenitor cells, osteoblast progenitor cells, osteoblast, pericytes, and multipotent stem cells.,,, A study by De Bari et al. reported that when the periosteal progenitor cells and stem cells were subjected to differentiation in culture medium, with good cell viability these cells were able to differentiate into various lineages: osteoblasts, fibroblasts, adipocytes, chondroblasts, and skeletal myocytes.
The periosteal eversion technique which is also called as perioplasty was first proposed by Gaggl et al., where periosteum was used to cover the denuded root surfaces. This technique involves the partial thickness flap reflection, eversion and reposition of flap coronally and is placed on the denuded root surfaces. In this case series, similar technique was used to cover the denuded surfaces of multiple roots. Virnik et al., used the similar technique to cover the single denuded root surface and has showed better results. Mahajan assessed the root coverage with periosteal pedicle graft for a period of 1 year in class I recession case and the results showed that the denuded root surfaces was covered completely. A recent report on isolated tooth root coverage using marginal periosteum as a pedicle graft by Singh and Kiran showed that at the end of 6 months, there was a completed coverage of denuded root surface covering 5 mm of gingival height leaving 1 mm of probing depth. In a recent study, comparing the periosteum eversion techinique and coronally advanced flap, both techniques showed equally effective in Miller's class I and II recession coverages.
It was also reported that, periosteum also contains cytokines and various growth factors such as transforming growth factor-β, platelet derived growth factor, insulin-like growth factor, bone morphogenic proteins 2 and 7. Periosteum itself acting as a scaffold with various cells possessing in it and numerous growth factors is an ideal source of tissue engineering.
| Conclusion|| |
Within the limits, with the several benefits of periosteum in terms of quality and quantity and less donor site morbidity, the periosteum can be successfully used as a root coverage material for denuded root surface as an end stage procedure or can be used as a preliminary procedure to cover the root surface that give support for orthodontic therapy in cases where other types of grafts will not be successful.
