هدف نهايي درمان هاي پريودنتال بازسازي كامل انساج از دست رفته به نحوي است كه با بافت هايي با همان عملكرد و ساختار، جايگزين شوند. باتوجه به نتايج اميدبخش مهندسي بافت در تسهيل رژنراسيون پريودنتال، هدف اين مطالعه مرور نظام مند بررسي رژنراسيون انساج پريودنتال تحت تاثير تغييردهنده هاي زيستي در ضايعات داخل استخواني مدل هاي حيواني است.
مواد و روش ها
با جست وجو در منابع اطلاعاتي، تمامي مطالعاتي كه به بررسي اثر تغييردهنده هاي زيستي بر بازسازي انساج پريودنتال در ضايعات داخل استخواني مدل هاي حيواني در بازه مارس 2020-2010 ميلادي پرداخته بودند، جمع آوري شدند. غربالگري مطالعات براساس معيارهاي مورد نظر انجام و ارزيابي كيفيت مقالات با ابزار SYRCLE صورت گرفت. سپس فراتحليل براي مطالعات واجد شرايط انجام شد.

The ultimate goal in periodontal treatment is to achieve a functional
and anatomical regeneration of lost tissues. Due to the promising outcomes of biologic modifiers in
regenerative therapies, this systematic review aimed at evaluating the effects of various biologic
modifiers used in intra-bony osseous defects in animal models.
Materials and methods: Electronic databases were searched for articles published in March
2010-March 2020 that had evaluated the effect of bio-modifiers used in periodontal intra-bony osseous
defects in animal models. Screening was performed based on inclusion/exclusion criteria and SYRCLE
tool was used for studies’ quality assessment.
Results: After screening the titles, abstracts, and full-texts, 18 studies were included in
qualitative analysis and five studies entered the meta-analysis. According to the configuration of osseous
defects, the studies were categorized into three subgroups. Based on histological findings, all these biologic
markers significantly enhanced new bone and cementum formation compared to control groups (P<0.001).
The meta-analysis showed that biologic modifiers could significantly increase bone regeneration
(1.58 mm, 95% CI: 1.12-2.03, P˂0.001) and cementum regeneration (1.27 mm, 95% CI: 0.84-1.70, P˂0.001)
in one-wall osseous defects.
Conclusion: Biologic modifiers namely growth factors could positively affect periodontal
regeneration, particularly the cementum and bone in animal models. Further human studies are necessary
to address the clinical use of these biomaterials.
