The objective of this study was to determine whether the local administration of stromal cell-derived factor-1 (SDF-1) using ultrapurified alginate gel (UPAL gel) could improve reparative tissues of osteochondral defects compared with those without treatment. For the investigation, a full-thickness osteochondral defect 4.5 mm in diameter and 3 mm in depth was created in the patella groove of th...

purpose: to present our experience with cyanoacrylate tissue adhesive in eyes with exposed hydroxyapatite orbital implants. methods: cyanoacrylate tissue adhesive was used in 3 patients with hydroxyapatite orbital implant exposure defects. results: cyanoacrylate glue was applied on the defective area of 3 patients presenting with small exposure (<4mm). the patients were followed for 33 months (...

Spontaneous herniation of the temporomandibular joint along a bony defect in external auditory canal is an uncommon condition that may lead to otologic symptoms. A 43-year-old gentleman presented with otalgia and soft tissue lesion, which flattens upon opening jaw. Computed tomography scan temporal region confirmed presence lesion herniated through wall defect. This should be included different...

Objective(s):Various methods for repairing bone defects are presented. Cell therapy is one of these methods. Bone marrow stromal cells (BMSCs) seem to be suitable for this purpose. On the other hand, lots of biomaterials are used to improve and repair the defect in the body, so in this study we tried to produce a similar structure to the bone by the chitosan and hydroxyapatite. Materials and Me...

periodontal regeneration is a main aspect in the treatment of teeth affected by periodontitis. periodontal regeneration in furcation areas is quite challenging, especially when it is in interproximal region. there are several techniques used alone or in combination considered to achieve periodontal regeneration, including the bone grafts or substitutes, guided tissue regeneration (gtr), root su...
