Os altos níveis de pH são, geralmente, verificados nos períodos iniciais, antes da completa presa dos cimentos, sendo o mesmo verificado no estudo, corroborando com outros estudos (DUARTE, et al, 2003;DE VASCONCELOS, et al, 2009;VIVAN, et al, 2010;SILVA, et al, 2014). O nível do pH diminuiu com o tempo, porém se manteve alcalino.…”

“…Este processo ocorre de maneira lenta, resultando em um tempo de presa em torno de 3 horas (TORABINEJAD, M., et al, 1995a (BORTOLUZZI, et al, 2009a;VIVAN, et al, 2010). Por outro lado, a liberação de íons cálcio mostra-se mais elevada para o cimento Portland com óxido de bismuto (DE VASCONCELOS, et al, 2009;VIVAN, et al, 2010).…”

“…Um aspecto que ocorre com os cimentos à base de silicato de cálcio é a liberação de íons cálcio e o pH mais elevados nos períodos inicias, logo após a sua manipulação (DUARTE, et al, 2003;DE VASCONCELOS, et al, 2009;VIVAN, et al, 2010). Com o decorrer do tempo, ocorre um declínio tanto da liberação de cálcio quanto do pH, porém ainda permanece alcalino (VIVAN, et al, 2010).…”

“…Com o decorrer do tempo, ocorre um declínio tanto da liberação de cálcio quanto do pH, porém ainda permanece alcalino (VIVAN, et al, 2010). Essa característica está relacionada à uma maior liberação dos íons cálcio e hidroxila logo após a manipulação até ocorrer a completa presa do cimento.…”

Objectives To examine the dimensional changes of endodontic sealers during 18 months using three‐dimensional (3D) surface scanning and subtraction radiography in a novel in vitro sealer‐extrusion model. Material and Methods Fifty endodontically instrumented acrylic teeth were randomly allocated to five groups ( n = 10) filled with Apexit Plus, AH Plus, BioRoot RCS, TubliSeal EWT, and gutta‐percha (control). Freshly mixed sealers were intentionally extruded during obturation. All teeth were immersed in a physiologic solution for up to 18 months. Blinded 3D surface scans (resolution: ~10 μm) and digital radiographs of the teeth were obtained at baseline (immediately after obturation); and then after 1 week, and at 1, 3, and 18 months. For blinded assessment of sealer dimensional change, 3D models and radiographs were superimposed using specific software. Volumetric differences, root mean square (RMS), and area change from subtraction radiography measured at each period within each sealer group were thereafter calculated. Repeated measures analyses were done with Bonferroni adjustment for multiple comparisons; standard errors, p values, and 95% confidence intervals (CI) were reported. Results Analyses of the volumetric data confirmed significant, progressive material loss for Apexit Plus when compared to the other investigated sealers or the control group ( p ≤ 0.02). Immersion period significantly influenced the volumetric dimensional changes of Apexit Plus already after 1 month ( p < 0.01). For TubliSeal EW, the effect of the immersion period on the dimensional changes was noted after immersion for 3 months ( p ≤ 0.02), while for BioRoot RCS this was evident only at 18 months ( p < 0.01). Same trends were noted for the RMS data, whereas progressive dimensional changes using subtraction radiography only revealed significant changes for Apexit Plus ( p = 0.01). Conclusions The largest dimensional changes were shown by Apexit Plus, followed by Tubliseal EWT and BioRoot RCS. AH Plus remained stable throughout 18 months.
