Enamel is a hard nanocomposite bioceramic with significant resilience that protects the mammalian tooth from external physical and chemical damages. The remarkable mechanical properties of enamel are associated with its hierarchical structural organization and its thorough connection with underlying dentin. This dynamic mineralizing system offers scientists a wealth of information that allows t...

Selective laser sintering (SLS), which is a additive rapid manufacturing technique, it is capable of producing the required product directly and automatically from a 3D computer model representation, have been selected to build implant and scaffold structures using composite materials consisting of a polymer and a bioactive ceramic. Hydroxyapatite (HA), a bioceramic that encourages bone apposit...

Introduction: This study compared the apical sealing ability of a bioceramic based root canal repair filling material (iRoot FS) with mineral trioxide aggregate (MTA). Methods and materials: Forty single-canal teeth were prepared and randomly divided into two experimental groups (n=18) and two control groups (n=2). Teeth in experimental groups were retrofilled with either MTA or iRoot FS. After...

BACKGROUND AND AIMS The aim of this study was to assess the radiopacity of two bioceramic-based root canal sealers, the conventional TotalFill BC sealer (FKG Dentaire Switzerland) and a new experimental filling material developed in collaboration with 'Raluca Ripan' Institute for Research in Chemistry, Cluj-Napoca. METHODS Five disc samples were prepared using both materials (10 mm diameter ×...

background: the aim of this study was to compare push-out bond strength of a new bioceramic endodontic sealer, endosequence bc sealer (brasseler usa, savannah, ga), used with gutta-percha in the presence or absence of phosphate-buffered saline solution (pbs) within the root canals. materials and methods: forty single-rooted human teeth were prepared and randomly divided into four groups. sample...

Abstract Hydroxyapatite (HAp) is a well-known bioceramic known for its high biocompatibility and good bioactivity. The structure of HAp mimics the natural bone thus, it widely used as implants hard tissues. Despite possessing above properties, lacks mechanical strength, susceptible to growth microbes over time has low degradability. Polymers can be synthetic or natural. They better choice addit...
