The structure of an osteochondral biphasic scaffold is required to mimic native tissue, which owns a calcified layer associated with mechanical and separation function. The two phases of biphasic scaffold should possess efficient integration to provide chondrocytes and osteocytes with an independent living environment. In this study, a novel biphasic scaffold composed of a bony phase, chondral ...

Fingertip amputation is a popular injury with variety of treatment methods from simple to complex, including skin graft, local flaps, regional and microsurgery anastomosis. One method that has been gaining attention recently secondary wound healing. This study aims evaluate the effectiveness second-stage healing care for bony proximal wounds. The authors used descriptive cross-sectional monitor...

The present study was performed to evaluate the effects of hydroxylapatite (HAP) on tissue regeneration in various types of furcation involvement. Upper premolar tooth sites of 9 beagle dogs (3-6 years old) were used. HAP particles were implanted into three types of furcation defects: Class III lesion (by Glickman) in 2nd premolar sites, artificially caused by intrafurcal suturing or spontaneou...

background: recently, there has been interest in non‑mammalian collagen sources such as fish collagen in the development of biomatrices and scaffolds for periodontal regeneration. in the present study, a novel collagen barrier membrane of fish origin was assessed in the treatment ofperiodontal intra‑bony defects. materials and methods: ten systemically healthy chronic periodontitis patients hav...

Background and Objective: The craniofacial structures are complex esthetically the most important component of appearance. Defects in this region lead to noticeable deformities that physically psychologically devastating patients. Advances grafting tissue transfer techniques have improved surgical outcomes but our ability fully regenerate lost or defective is limited. purpose narrative review g...

Adenosquamous carcinoma is an aggressive and rare variant of squamous cell that has both glandular differentiation. We present a case occipital scalp adenosquamous in 43-year-old male who presented with mass was initially marble size, which progressively enlarges over years. There were no constitutional symptoms. No neurological deficit locoregional lymph nodes not palpable. Contrast enhanced c...

AIM To evaluate the integration of implants installed at the interface of pristine and grafted tissue augmented with particulate autologous bone or deproteinized bovine bone mineral (DBBM), concomitantly with a collagen membrane. MATERIAL AND METHODS In 6 Labrador dogs, the distal root of (3)P(3) and (4)P(4) was endodontically treated and hemi-sected, and the mesial roots extracted concomitan...
