Titanium (Ti) implants are extensively used in a number of biomedical and dental applications.This work introduces Ti into the glass phase of a zinc based Glass Polyalkenoate Cement (GPC) and investigates changes in handling and mechanical properties considering two molecular weight polyacrylic acids (PAA), E9 and E11. Considering the handling properties, the working time (T w ) increased from 50s E9 , 32s E11 (BT 101, Ti-free) to 169s E9 , 74s E11 with TW-Z (highest Ti content) respectively. The setting time (T s ) increased from 76s E9 , 47s E11 (BT 101) to 303s E9 , 232s E11 with TW-Z respectively. Ti was also found to have a significant increase on both compressive (σ c ) and biaxial flexural strength (σ f ), where σ c increased from 36 MPa E9 , 56 MPa

“…It was stated that the pure C 3 S has good bioactivity 24 , the ability to be coated with HA 25,26 and maintenance of the bonebiomaterial interface once implanted 27 . Also C 3 S has been proved to have adequate physical properties 21 , shorter setting time than MTA, and acceptable in vitro degradability (the ability for the implanted cement to be replaced by natural tissue) 27 .…”

Nano particles made of pure single phase Mineral trioxide [tricalcium silicate (C 3 S)] and Tetracalcium phosphate (TTCP) bio ceramics were prepared via solid state reaction at high temperature. Setting times, compressive strength, pH, XRD, FTIR and scanning electron microscopy (SEM) were investigated. Cytotoxicity and antibacterial activity of both C 3 S and TTCP to human gingival fibroblasts were studied. Both C 3 S and TTCP compounds undergo hydration reaction when mixed with distilled water. A delayed setting time and very poor mechanical properties for TTCP were detected compared to those of C 3 S phase. The nano-structure C 3 S bio ceramic was found to be completely safe to BHK cells compared with TTCP. The prepared C 3 S and TTCP pastes were applied to the demineralized dentin specimens for seven days. The ultramorphology of dentin revealed that both C 3 S and TTCP are successful in dentinal tubules occlusion, thus they are beneficial for dental application in the treatment of teeth hypersensitivity.

“…There is a history of use in the literature for 'hydraulic silicate cement' , 'calcium silicate cement' and 'hydraulic calcium silicate cement' (13)(14)(15). The term 'hydraulic cement' is a term that originates in the engineering literature and refers to materials that react 'under water' , which can be extended to include GICs and related glass-based cements that set using acid-base aqueous reactions (16).…”

Objective: Under the Global Medical Device Nomenclature (GMDN) system, the newly introduced term 'hygroscopic dental cement' (HDC) encompasses MTA as well as cements based on bioceramics, calcium silicate or calcium sulphate. Many HDCs have a long history of use in dentistry. There is a need for a consistent, logical and informed approach to the nomenclature of traditional and novel HDCs. Methods: Commercial manufacturers of HDC were contacted requesting information on the compositions of products. Manufacturers that were unknown to the authors, that were unable to be contacted, that wished to be excluded from this paper, or that did not send their information on compositions in due time were not included. Results:The compositions of commercial HDCs include various hybrids of calcium silicates, calcium aluminates, calcium phosphates, calcium sulphate as well as zinc sulphates. Furthermore, there are variations in the radiopacifier as well as additives that change the handling or setting processes. Conclusion:The inclusion of different additives to HDCs enables variation in handling properties such that they now exist as distinct putties and sealers as well as cements.
