ABSTRACT
Background: Intracanal medicaments Ca(OH)2 must have the ability to contact
directly with bacteria adhering to the dentinal tubules. However, the narrow and
complex shape of the root canal makes it difficult for Ca(OH)2 to penetrate the root
canal apically. This study aimed to evaluate the flowability of Ca(OH)2 nanoparticle
synthesized from CaCO3 source from natural limestone in Palimanan, Cirebon,
West Java, Indonesia with an average particle size of 278 nm by quantifying the
penetration of the coronal, middle, and apical thirds of the root canal.
Methods: This research comprised two distinct groups: one group included
nanoparticles of Ca(OH)2 Palimanan, while the other consisted of conventional
Ca(OH)2. The paste was then applied to standardized root canals (n=3 per group)
with 5 times measurements for each sample. All samples were then incubated at
37oC, 100% humidity. The flowability of the root canals was measured using
scanning electron microscopy (SEM) on day 14. The data was analyzed using
ANOVA and a post-hoc t-test, with a significance level of p
