[ 1 ] - بررسی کارایی پلیت روی مخاطی در درمان شکستگی‌های تیغه کامی فک فوقانی
مقدمه: در ترومای ناحیه میانی صورت، شکستگی‌های کامی اغلب با شکستگی‌های فک فوقانی (لفورت) همراه هستند. این شکستگی‌ها ممکن است چالش‌هایی در تشخیص و درمان به وجود آورند و اگر به‌طور صحیح درمان نشود منجر به مشکلات بد جوش خوردن، مال اکلوژن و فیستول دهانی ـ بینی می‌شوند. هدف از این مطالعه، بررسی کارایی مینی پلیت معمولی روی مخاطی در درمان شکستگی تیغه کامی فک فوقانی بود. مواد و روش‌ها: در بیماران با تشخ...
[ 2 ] - بررسی اثر فرایند سلول زدایی بر بافت غشاء اشنایدریان سینوس فک بالا به عنوان داربست در مهندسی بافت
مقدمه: واژه ماتریکس بیولوژی جایگاه مهمی در تحقیقات بیولوژی و پزشکیاخیر کسب نموده است. در بافتهای زنده سلولها توسط یک ساختار به نام ماتریکس خارج سلولی حمایت می‌شوند. ماتریکس خارج سلولی به عنوان یک داربست برای مورفوژنز بافتی، تکثیر،مهاجرت، تمایز بافتی و حفظ این تمایز عمل میکند. ماتریکس خارج سلولی درمهندسی بافت جهت جایگزینی بافتی استفاده شود.بافت غشای سینوس حاوی سلول و ماتریکس خارج سلولی متشکل ...
[ 3 ] - In vitro Assay of Human Gingival Scaffold in Differentiation of Rat’s Bone Marrow Mesenchymal Stem Cells to Keratinocystes
Objective(s)Tissue engineering is an attractive science because it promises new therapeutic strategies for repairing organs that have lost functions due to damage. The purpose of this study was to evaluate induction effect of human gingival scaffold in tissue engineering for skin regeneration.Materials and MethodsTissue samples were obtained from crown-lengthening procedures and wisdom teeth re...
[ 4 ] - Reconstruction of Lateral Mandibular Defects with Soft Tissue Loss: The Role of the Submental Flap
Introduction: Mandibular continuity defects after pathologic resections or traumatic events are difficult cases for reconstruction. Defects involving both hard and soft tissue loss are more challenging, because of problems in soft tissue coverage. The role of the submental flap in this regard is presented. Materials and Methods: In a retrospective study from the archived files of Ghaem Hospi...
[ 5 ] - The Role of Lingual Bone Grafting in the Treatment of Displaced Edentulous Mandibular Fracture with Severe Atrophy
Introduction: Treatment of edentulous atrophic mandible with severe atrophy is a challenge based on local conditions and systemic diseases confronted by the age group affected. If bone grafting is indicated, it is often used in lateral or inferior aspects of the mandible. Case Report: A 70-year-old male with a unilateral fracture of the atrophied left mandibular body was managed by lingual bon...
[ 6 ] - Random Pattern Vertically Oriented, Partial Thickness Buccinator Myomucosal Flap for Intraoral Reconstruction: A Report of Two Cases
Introduction: Reconstruction of the oral cavity witha flap design containing the buccal mucosa and buccinator muscle but excluding the facial artery and vein is the topic of these case reports. Case Reports: This article uses random pattern vertically oriented partial thickness buccinator myomucosal flap for intraoral reconstruction in two cases. The first was for lining the mandibular anterior...
[ 7 ] - Primitive Neuroectodermal Tumor of the Kidney
Primitive neuroectodermal tumor (PENETs) is an uncommon malignancy of bone and soft tissue witch rarely occurs in the kidney. In more than 90% of the cases, the tumor cells relieves a balanced translocation (11; 22) (q24; q12). Immunohistochemical staining may be required for diagnosis of PENET. The cells of tumor express CD99, vimentin, NSE, FL1 but do not express Ck, LCA, myogenin, and WT1. W...
[ 8 ] - Central Odontogenic Fibroma
In 1991, Handlers and colleagues described the Central odontogenic fibroma (COF) as a distinct entity which is a rare benign odontogenic tumour and up to the present, only 78 cases of it have been published. COF usually occurs in an adult patient and has a predilection for the anterior region of the jaws. A 2.8:1 female to mail ratio is typically noted. This article presents a case of COF in a ...
[ 9 ] - Apical Force Application in the Management of Dentoalveolar Fractures: Indications, Procedure and Limitations
Dentoalveolar fracture is defined as a fracture in the bone surrounding the teeth without any extension to the basal bones of the maxilla or mandible (1). As for other parts of the facial skeleton, the treatment strategy for dentoalveolar fractures consists of fracture reduction, fixation and immobilization (2); however, some dentoalveolar fractures are difficult to treat. In some dentoalveola...
[ 10 ] - Biologic Basis of De-Epithelialized Transverse Platysma Flap for Oral Cavity Reconstruction
Introduction: The inferiorly and laterally based platysma myocutaneous flap contains hair in some ethnics; therefore, it is required to change the myocutaneous flap to myofascial flap to prevent the hair growth after its transfer to the oral cavity. Materials and Methods: Five male mongrel dogs were selected for this study. De-epithelialized laterally based platysma fl...
