| Abstract [eng] |
The objective of this study was to assess the porosity distribution of BioRoot RCS/singlegutta-percha point root-canal fillings performed by a general dental practitioner and endodontist.Fourteen plastic models of maxillary premolars with two roots were selected and shaped with HyFlexEDM instruments to a size 40/0.04 taper and randomly divided into two experimental groups. Atotal of 14 canals in each group were obturated by two different operators with one HyFlex EDM size40 gutta-percha point and BioRoot RCS sealer. The specimens were scanned with a high-resolutionmicro-computed tomography scanner, and the porosity of the fillings at the coronal, middle, andapical thirds of the root canals was qualified and quantified. The differences between groups androot-canal thirds were compared using Mann–Whitney, Friedman, and Wilcoxon tests with thesignificance level set atp< 0.05. The highest number of pores was observed in the apical third ofroot-canal fillings in both groups; however, the porosity distribution between the two groups was notsignificantly different in the apical and middle thirds (p> 0.05). Statistically significant differenceswere determined only in the coronal third (p< 0.05). The predominance of open pores was detected inall root-canal thirds and groups, with no significant differences in the number of open pores betweenthe coronal and middle thirds (p> 0.05). |
