Evaluation of stress generation in core build up-material of mutilated primary teeth: a comparative finite element analysis between BioFlx, stainless steel and zirconia crowns.

Stainless-steel crowns (SSCs) are the most durable restorative option for deciduous teeth, although they are unsightly. However, prefabricated zirconia crowns (ZCs) look more pleasant but require substantial dental preparation. Recently, BioFlx crowns have been introduced as a white-colored alternative to SSCs, providing both flexibility and aesthetics.

Scaffolds--The Ground for Regeneration: A Narrative Review.

Aim: The aim of this study was to comprehensively review the various biomaterials used as scaffolds, rates of biodegradability of natural, artificial and composite hybrid scaffolds, and the role of controlled biodegradability in tissue engineering.

Materials And Methods: An electronic search for systematic review was conducted in PubMed/MEDLINE (www.ncbi.
