Análise da composição química dos cimentos MTA Angelus® branco, cinza e HP Repair® através de Microscopia Eletrônica de Varredura (MEV) acoplada a Espectrômetro de Energia Dispersiva (EDS)

ABSTRACT:
Após a análise dos elementos químicos, foram observados para o MTA branco: O, Na, K, Mg, Al, Si, Ca e Bi; para o MTA cinza: O, Mg, Al, Si, Ca, Bi, Fe e S, e para o Repair HP: O, Al, Mg, Si, Ca, Fe, Sr, C, Rb e W. Foram identificados 14 elementos químicos nas amostras analisadas (O, Na, Al, Mg, Si, S, K, Ca, Fe, Sr, Bi, C, Rb e W). Destes, cinco foram encontrados em todos os cimentos estudados: O, Al, Mg, Si e Ca. Conclusão: Os elementos Rb, W e C foram encontrados somente na nova formulação de MTA da Angelus, o Repair HP. Nas amostras analisadas, o Ca e o O foram os que se apresentaram em maior quantidade.

Physicochemical, cytotoxicity andin vivo biocompatibility of a highplasticity calcium-silicate basedmaterial

ABSTRACT:
MTA HP showed similar in vivo biocompatibility to the WMTA and the control group in all time-points. The MTA HP presented adequate physicochemical and biological properties with improved flow ability when compared to WMTA. Such improved flow ability may be a result of the addition of a plasticizing agent and should be related to an improvement in the handling of MTA HP.

Biological effects of acid-eroded MTA Repair HP and Pro Root MTA on human periodontal ligament stem cells

ABSTRACT:
These results may suggest that MTA Repair HP and ProRoot exhibited optimal biological properties in terms of cell viability, cell death and cell attachment in acidic environment, being considered as materials for root-end filling and perforations.

Addition of phosphates and chlorhexidine to resin-modified MTA materials

ABSTRACT:
The addition of phosphates and chlorhexidine to resinmodified MTA was performed to synthesize a novel type of endodontic sealer for root-end filling procedure. This study showed that MTA resin-modified root-end fillings without chlorhexidine digluconate are promising materials for endodontic treatments, since these experimental sealers presented effective physico-chemical and biological properties.

The effects of sodium hypochlorite and ethylenediaminetetraacetic acid on the microhardness of Mineral Trioxide Aggregate and Total Fill Bioceramic Putty

ABSTRACT:
MTAA had a higher baseline microhardness than BCP. NaOCl reduced the microhardness of MTAA but increased that of BCP. EDTA reduced the microhardness for both materials at 24 h. At 8 days, EDTA reduced the microhardness of MTAA, while BCP exhibited an increase in microhardness. Enabling these materials to set for a week prior to exposure to irrigants improves their microhardness.
