“…In the present study, the null hypothesis was rejected, as significant differences were found between the calcium silicate-based materials in most of the evaluated parameters. Although previous studies have evaluated BD using similar methodologies (Adl et al, 2019;Farrugia et al, 2018;Marconyak et al, 2015;Ochoa-Rodrıguez et al, 2019;Ochoa-Rodriguez et al, 2020;Oliveira et al, 2020;Shokouhinejad et al, 2016;Vallés et al, 2015;Yoldas et al, 2016), few studies have used BCT (Guerreiro et al, 2021;Oliveira et al, 2020;Villa et al, 2020) and BCR (Benetti et al, 2019;Ghilotti et al, 2020;López-García et al, 2019), which are new ready-to-use materials. To assess crown discolouration by these materials in the presence of blood components, a model was designed to simulate the clinical situation of partial pulpotomy.…”
