  • Protocol summary

    In a double blinded clinical trial using split-mouth design twelve periodontally healthy patients, aged over 18 years with lack of adequate attached gingiva on at least two sites in the mandible are included in the study. Patients with any systemic disease or condition affecting wound healing such as diabetes; Use of immunosuppressive medications; Current or former smokers; Inadequate oral hygiene are excluded from the study. Subsequent to recipient site preparation, a standardized 10*15 mm template is used to harvest a graft from premolar and first molar area of the hard palate and is fixed in the recipient site. On the day of surgery and 2 days after surgery, on the test site 1ml of the gel containing 4,000 IU ml-1 Erythropoietin and on the donor site, 2ml gel with out Erythropoietin is applied on the wound. Then the wound sites are covered with a foil and the coe-pak is placed over them. Clinical examinations Epithelialization A 3% H2O2 was utilized to evaluate the wound epithelialization rate on days 7, 14, 21, 28 after surgery. The results are reported as 0,1/3,2/3, 3/3, for each wound site.

    در یک مطالعه کار آزمایی بالینی split mouth و double blinded دوازده بیمار بالای 18 سال که حداقل در دو ناحیه از فک پایین دارای کمبود عرض لثه کراتینیزه هستند انتخاب می شوند. معیارهای حروج:ابتلا به بیماری های سیستمیک و یا هرگونه بیماری که با ترمیم زخم تداخل داشته باشد از قبیل دیابت؛ مصرف داروهای تضعیف کننده سیستم ایمنی؛ سابقه مصرف سیگار در گذشته یا حال؛ پلاک کنترل ناکافی پس از آماده سازی ناحیه گیرنده با استفاده از یک تمپلیت استاندارد با اندازه 10 در 15 میلیمتر بافت پیوندی از ناحیه کام دندان های پرمولر و مولر اول برداشته می شود و در ناحیه گیرنده توسط بخیه ثابت می شود. پس از کنترل خونریزی در روز جراحی و 2 روز بعد، در ناحیه تست 1 میلی لیتر ژل حاوی اریتروپوییتین 4000 واحد و در ناحیه کنترل 2 میلی لیتر ژل فاقد اریتروپوییتین قرار داده می شود.در انتها هر دو ناحیه توسط فویل و coe-pak پوشانده می شود. میزان اپیتلیزاسیون با قرار دادن H2O2 3% در ناحیه در روزهای 7و14و21 و 28 پس از جراحی بررسی می شود. نتایج به صورت 0، 1/3، 2/3، 3/3 برای هر ناحیه گزارش می شود.

    A standardized 10*15 mm graft is harvested from premolar and first molar area of the hard palate. In the donor site: On the day of surgery and 2 days after surgery, on the test site 1ml of the gel containing 4,000 IU ml-1 EPO and on the donor test site, 2ml gel without EPO is applied on the control site. In the recipient site: Test sides are treated with 1 ml erythropoietin (EPO) 4000 IU and the control sites receive 1 ml of distilled water. After two minutes, the harvested gingival graft is stabilized with synthetic absorbable 4/0 sutures. both sites are then covered with surgical dressing. The outcomes are evaluated on days 7,14,21,28,60,90.

    Control group: A 10*15 mm template is used to harvest a graft from premolar and first molar area of the hard palate and is fixed in the recipient site. In control site: After bleeding control in the donor site, the day of surgery and 2 days after surgery 1ml of the hydroxy ethyl cellulose without Erythropoietin is applied on the wound site. Then the wound sites are covered with a foil and the periodontal pack (coe pak, GC America) is placed over them.

The control sides receive 1 ml of distilled water. After two minutes, the harvested gingival graft is adapted on the site and stabilized with synthetic absorbable 4/0 sutures (Polyglycolate coated; SUPABON, SUPA, Iran). Then the wound sites are covered with a foil and the periodontal pack (coe pak, GC America Co., USA).
    گروه کنترل: در ابتدا یک تمپلیت در ابعاد 10 * 15 میلیمتر تهیه شده و از ناحیه کام پرمولر دوم و مولر اول پیوند با ضخامت 1.5 میلیمتر برداشته می شود و توسط نخ قابل جذب ویکریل 0-4 ، در ناحیه گیرنده ثابت می شود.بعد از کنترل خونریزی در روز جراحی و دو روز بعد از جراحی 1 cc از ژل با غلظت 1.5% تهیه شده از ماده هیدروکسی اتیل سلولز بدون اریتروپوییتین توسط سواب در محل زخم کام به کار برده می شود. ناحیه دهنده و گیرنده توسط فویل و پک پریودنتال (coe pak) پوشانده می شود.

Protocol summary

Study aim
Evaluating the effect of local Erythropoietin(EPO) on palatal wound epithelialization and healing and inflammation in free gingival graft(FGG) recipient site
Design
This is a split-mouth randomized controlled clinical trial on seventeen patients who need FGG for at least two sites in mandible. The patient, the surgeon, the initial and final examiner, and the data analyzer are blinded to the intervention.
Settings and conduct
A standardized 10*15 mm graft is harvested from premolar and first molar area of the hard palate. In the donor site: On the day of surgery and 2 days after surgery, on the test site 1ml of the gel containing 4,000 IU ml-1 EPO and on the donor test site, 2ml gel without EPO is applied on the control site. In the recipient site: Test sides are treated with 1 ml erythropoietin (EPO) 4000 IU and the control sites receive 1 ml of distilled water. After two minutes, the harvested gingival graft is stabilized with synthetic absorbable 4/0 sutures. both sites are then covered with surgical dressing. The outcomes are evaluated on days 7,14,21,28,60,90.
Participants/Inclusion and exclusion criteria
Inclusion criteria : 1) age of 18 years old or above; 2) periodontal health; Exclusion criteria: 1) compromised systemic health, such as diabetes mellitus and immune suppression; 2) consumption of anti-inflammatory or antibiotics during last 3 months; 3) smoking, and 4) O’Leary plaque index>15% after phase I periodontal therapy.
Intervention groups
Application of Gel with or without EPO on test or control sites of palate. application of EPO or stilled water on test or control sites before graft suturing.
Main outcome variables
epithelialization rate in palate healing degree in recipient site inflammation around recipient site

Scientific title
The Eeffect of Topical Erythropoietin on Palatal Wound Healing Subsequent to Free Gingival Graft in patients with insufficient keratinized gingiva. Evaluation of Topical Erythropoietin Application on the Healing Outcome of Gingival Graft Recipient Site; A Randomized Controlled Clinical Trial.
Public title
Effects of erythropoietin in palatal wound healing, Effect of Erythropoietin on healing of gingival graft
Purpose
Supportive
Inclusion/Exclusion criteria
Inclusion criteria:
age of 18 years old or above periodontal health; need for gingival graft in order to augment keratinized gingiva in at least two mandibular areas
Exclusion criteria:
Age
From 18 years old
Gender
Both
Phase

Sample size
Target sample size: 24
Randomization (investigator's opinion)
Randomized
Randomization description
Balanced block randomization was used to allocate each patient into one of the following categories: - Right side surgery first, treated with distilled water on recipient site and gel without EPO on donor site - Right side surgery first, treated with EPO on recipient site and gel containing EPO on donor site - Left side surgery first, treated with distilled water on recipient site and gel without EPO on donor site - Left side surgery first, treated with EPO on recipient site and gel containing EPO on donor site
Blinding (investigator's opinion)
Triple blinded
Blinding description
The patient, the surgeon, the initial and final examiner, and the data analyzer are blinded to the intervention. To meet the assumptions of randomization, a number of sealed non-transparent coded envelopes are prepared with letters A, B, C, or D printed on them. A third individual opens each envelope and explains the sequence of surgery and gel application to the surgeon.

Intervention groups

1

Description
Control group:A 10*15 mm template is used to harvest a graft from premolar and first molar area of the hard palate and is fixed in the recipient site.In control site: After bleeding control in the donor site, the day of surgery and 2 days after surgery 1ml of the hydroxy ethyl cellulose without Erythropoietin is applied on the wound site.To prepare the bed, a split thickness horizontal incision at mucogingival junction (15 mm long) and two vertical incisions at both ends (10 mm long) is made with scalpel blade no. 15. The control sides receive 1 ml of distilled water. After two minutes, the harvested gingival graft is adapted on the site and stabilized with synthetic absorbable 4/0 sutures (Polyglycolate coated; SUPABON, SUPA, Iran). Then the wound sites are covered with a foil and the periodontal pack (coe pak, GC America Co., USA).
