摘要
Aim This randomized clinical trial evaluated clinical sign/symptoms as well as histological pulp reactions in terms of inflammation and mineralized bridge formation after partial pulpotomy of sound human premolars and placement of a bioceramic paste (iRoot BP) or tooth-colored ProRoot MTA as pulp-covering biomaterials. Methodology Twenty-four human sound premolars were randomly allocated into two experimental groups (n = 12) treated either with iRoot BP or MTA subsequent to partial pulpotomy. Six weeks after treatment, clinical sign/symptoms and radiographic changes were evaluated. The teeth were then extracted and examined histologically for inflammatory status of the pulp, formation of hard tissue bridge and appearance of the bridge. In terms of pulp inflammation and dentinal bridge formation, the Mann-Whitney U, and for clinical signs, the chi-square test was used (alpha = 0.05). Results In terms of pulp inflammation, formation of hard tissue bridge and its appearance, the differences between the two experimental groups were not significant. However, clinical sensitivity to cold was significantly less for teeth treated with MTA (P < 0.05). All cases had formed a hard tissue bridge, and none of the specimens in either group had pulpal necrosis. Conclusion When treating teeth with healthy pulps, the response to partial pulpotomy treatment with both MTA and iRoot BP was favourable. However, pulps covered with iRoot BP were more sensitive to cold stimuli.
