background: since the treatments of long tracheal leisions are associated with some limitations, tissue enginered trachea is considered as an alternative option. this study aimed at preparing a composite scaffold, based on natural and synthetic materials for tracheal tissue engineering. methods: nine chitosan silk-based scaffolds were fabricated using three freezing rates (0.5, 1, and 2°c/min) ...

BACKGROUND Calcaneal fractures are relatively rare and difficult to treat. Treatment options vary based on the type of fracture and the surgeon's experiences. In recent years, surgical procedures have increasingly been used due to the better long-term results. We present a case where guided tissue regeneration was performed in a calcaneal fracture that needed primary subtalar arthrodesis. We us...

abstract this experiment was conducted for optimizing a suitable medium for callus induction, regeneration and rooting of anthurium. leaf and petiol explants of antadra and casino varieties were used for callus production. ms medium was supplied with growth regulators (naa, ba, kin and iba). a complete randomized design with 3 replication was used in this expriment. result indicates that variet...

INTRODUCTION The purpose of this study was to determine factors and clinical situations that influence an endodontist's decision to use guided tissue regeneration (GTR) techniques during endodontic root-end surgery. METHODS An invitation to participate in a web-based survey was e-mailed to 3,750 members of the American Association of Endodontists. Data were collected from 1,129 participants, ...

Tissue engineering in the orofacial region with bioactive components by activation of immune complexes or other proteins is current focus biomaterials research. Consequently, natural ground materials and tissue are being created. Bioactive glass one most promising has properties making it suited for a range different clinical dental applications, including regeneration hard tissues craniofacial...
