Micropush-out dentin bond strength and bioactivity analysis of a bioceramic root canal sealer

Penetration of bioceramic and epoxy-resin endodontic cements into lateral canals

“…Bioceramic cements show excellent tissue biocompatibility, mainly because they induce the formation of hydroxyapatite during the setting of the material. 8,11,12 The results obtained in the present study are related to laboratory studies, where conditions were carefully reproduced to simulate the natural environment and the anatomical characteristics of the dental element as much as possible; therefore, precautions should be taken when extending these to clinical settings.…”

“…11 Recently, a study demonstrated that the Endosequence BC Sealer indicated bioactivity, as hydroxyapatite was formed after setting of the material. 12 This characteristic is fundamental for its biological and physical-chemical properties. [8][9][10][11][12] AH Plus is an epoxy-based resin endodontic sealer that presents excellent physical-chemical properties including high radiopacity, 9 suitable flow 9 , and excellent bond strength with dentin.…”

Cimentos biocerâmicos em endodontia: revisão de literatura

“…Os materiais EndoSequence Root Repair Material (ERRM) 10,13 , BioAggregate e iRoot 11 , ProRoot MTA and MTA-Angelus 13 e Endosequence BC sealer 14,18 apresentaram biocompatibilidade aceitável, não induzindo efeitos citotóxicos críticos 12 . Um material bioativo é capaz de interagir com tecidos vivos, resultando na formação de uma camada de apatita, biomineralização, na interface material-tecido 39,40 .…”

“…Assim, a avaliação da formação de apatita na superfície de um material, quando exposta a um fluido corporal simulado, é um método aprovado para examinar a bioatividade in vivo dos tecidos duros 40 . A bioatividade de materiais biocerâmicos endodônticos foi confirmada no Bioagregado 12 , EndoSequence Root Repair Material 12,18 , ProRoo tMTA 12 , iRoot SP 17 . Com relação à adaptação marginal, essa propriedade foi considerada aceitável para materiais biocerâmicos 21,22 , com elevada resistência adesiva nas paredes do canal radicular 24,25 , as quais sofrem pouca influência dos métodos de irrigação 16 .…”
