Evaluation of the biocompatibility, antibacterial and anticancer effects of a novel nano-structured Fe-Mn-based biodegradable alloys in-vitro study.

Scientific Backgrounds: Development of nanostructured biodegradable alloys has generated a great deal of interest in the recent years as they offer promising bioactive materials for reconstruction of bony defects following traumatic fractures or surgical excision of tumors.

Objectives: The aim of the current study was to investigate the biocompatibility of Iron-Manganese -based alloys (Fe-Mn) with addition of copper (Cu), Tungsten (W) and cobalt (Co) to obtain 3 different alloys namely, Fe-Mn-Cu, Fe-Mn-W, and Fe-Mn-Co on normal oral epithelial cell line,and their possible anticancer effect on MG-63: osteosarcoma cell line.

Materials And Methods: The sulforhodamine B (SRB) assay was used to assess cell viability percentage of both cell lines after exposure to discs of the proposed experimental alloys.

A retrospective analysis of 5-year post surgery recurrence of N0 neck and the role of methylene blue in sentinel lymph node biopsy.

Unlabelled: of this study is to perform a retrospective analysis of the feasibility of the clinical application of SLNB using methylene blue dye (MBD) for the identification of SLN followed by frozen section biopsy to detect occult metastasis in clinically N0 necks. Hence, to know the reliability of MBD in reducing the need for extensive surgery.

Methods: We retrospectively analyzed the clinic pathological data of 48 patients with early oral cancer.

Functional outcomes after using the glenoid fossa as a fixed anchorage for the temporomandibular joint discopexy in patients with disc displacement without reduction.

The aim of the present study was to evaluate the use of the glenoid fossa as an anchorage for the temporomandibular joint (TMJ) disc repositioning in patients with a disc displacement (DD) without reduction. A prospective case series study included patients with DD without reduction. According to the Wilkes staging system for the TMJ internal derangement, preoperative magnetic resonance imaging (MRI) scans and clinical examinations determine the stage of the DD.
