The Therapeutic Effects of Mesenchymal Stem Cells and their Secretome on Oral Squamous Cell Carcinoma.

Oral cancers are prevalent in the human population, particularly in unindustrialized countries. In 90 % of oral cancers, the tumors arise from squamous cells, which is called oral squamous cell carcinoma (OSCC). Despite new treatment strategies, the morbidity and mortality rates are still high.

Recent Approaches to Enhance Osteogenesis of Dental Pulp Stem Cells on Electrospun Scaffolds.

Critical-sized bone defects are a challenging issue during bone regeneration. Bone tissue engineering is aimed to repair such defects using biomimicking scaffolds and stem cells. Electrospinning allows the fabrication of biocompatible, biodegradable, and strengthened scaffolds for bone regeneration.

Fracture strength and three-dimensional marginal evaluation of biocompatible high-performance polymer versus pressed lithium disilicate crowns.

Statement Of Problem: Despite the acceptable physical properties of biocompatible high-performance polymer (BioHPP), little is known about the marginal accuracy and fracture strength of restorations made from this material.

Purpose: This in vitro study assessed the marginal and internal adaptation and fracture strength of teeth restored with lithium disilicate (LD) ceramics and BioHPP monolithic crowns.

Material And Methods: Twenty-four extracted premolars were prepared for complete coverage crowns and divided into 2 groups to receive pressed IPS e.
