Introduction
Bioceramic and Mineral Trioxide Aggregate (MTA) root canal
sealers were recently introduced into the endodontic feld to beneft
from the formation of hydroxyapatite during the setting reaction in
the presence of tissue fuid and establish a chemical bond at the dentin
interface [1]. Solubility, pH changes and released elements of root canal
sealers have an impact on their clinical, biological and antibacterial
behaviors. Most sealers exhibit a variable degree of solubility that afects
the integrity of the apical seal of a root canal flling [2]. Terefore,
insolubility is a standard property for root canal sealer. Te alkaline
pH is closely related to the increased hydroxyl and calcium ion (Ca
2+
)
release afer root canal obturation, which inhibits growth of residual
microbes, and this enhances healing of periapical pathosis [3,4].
Recent Calcium Silicate Sealers (CSS) have been claimed to be
excellent sealers with alkaline pH, low solubility and providing good
sealing owing to their setting expansion [5]. To date, there are not
enough publications that prove their physiochemical behavior.
Te aim of this study was to evaluate solubility, pH changes, calcium
ions released and degradable elements of diferent brands of CSS. Te
null hypothesis is that there is no signifcant diference between the
tested root canal sealers.

According to American Dental Association (ADA) specifcation
number 57 for root canal flling, standard discs (15 mm diameter, 3 mm
thickness) of fresh mixed sealers were prepared (10 for each material),
according to manufacturer instructions. Tey were lef in an incubator
at 37

impermeable nylon thread and the initial weight (W

an analytical balance machine (Balance and Scale Model AW-220,
Shimadzu Corporation, Kyoto, Japan). Ten they were immersed in
20 ml deionized water and incubated for 1, 7, 14 and 28 days in 100%
humidity at a constant temperature of 37

Abstract
Introduction: Bioceramic technology has been introduced recently in endodontics to beneft from the formation of
hydroxyapatite during the setting reaction in the presence of tissue fuid and establish a chemical bond at the dentin interface.
Objectives: To evaluate some of physiochemical properties of new different Bioceramic (iRoot-SP, EndoSequence,
Smartpastebio) versus mineral trioxide aggregate (MTA-Fillapex) root canal sealers. Adseal and ActiV-GP sealers
were used as control.
Methods: Standard discs (10 for each) were prepared and immersed in 20 ml deionized water. After 1, 7, 14 and
28 days, solubility, pH changes and released elements were calculated and statistically analyzed with ANOVA test.
Results: A signifcantly greater solubility and higher alkalinity were displayed by the tested sealers (in
descending order) Smartpastebio, iRoot-SP, EndoSequence and MTA-Fillapex (P<0.05). Their solubility exceeded
the acceptable limit (3%). Their maximum alkaline pH was exhibited after 7 days. Adseal and ActiV-GP exhibited
initial neutral and acidic pH respectively. Finally both had neutral pH. EndoSequence exhibited the signifcantly
greatest calcium release followed by iRoot-SP, Smartpastebio and MTA-Fillapex, whereas, ActiV-GP and Adseal
exhibited the signifcantly lowest values (P<0.05). There was no silicon released from iRoot-SP, Smartpastebio
and MTA-Fillapex. ActiV-GP exhibited the greatest silicon, aluminum and iron release. The greatest phosphorous,
manganese and magnesium content was obtained by Adseal, MTA-Fillapex and EndoSequence respectively.
Conclusion: Under the condition of this study, the prolonged alkalinity of calcium silicate sealers was synchronized
with their ongoing solubility. The higher calcium ions released indicated strong alkalinity. The inequality in aluminum,
iron, manganese and magnesium released by the tested sealers may expect the variance in their behaviors.
