Abstract
Introduction: The aim of this study was to compare the
incidence of root cracks observed at the apical root
surface and/or in the canal wall after canal instrumenta-
tion with 3 single-file systems and the ProTaper system
(Dentsply Maillefer, Ballaigues, Switzerland). Methods:
One hundred mandibular incisors were selected. Twenty
control teeth were coronally flared with Gates-Glidden
drills (Dentsply Maillefer). No further preparation was
made. The other 80 teeth were mounted in resin blocks
with simulated periodontal ligaments, and the apex was
exposed. They were divided into 4 experimental groups
(n = 20); the root canals were first coronally flared with
Gates-Glidden drills and then instrumented to the full
working length with the ProTaper, OneShape (Micro-
Mega, Besancon, France), Reciproc (VDW, Munich,
Germany), or the Self-Adjusting File (ReDent-Nova, Ra’a-
nana, Israel). The apical root surface and horizontal
sections 2, 4, and 6 mm from the apex were observed
under a microscope. The presence of cracks was noted.
The chi-square test was performed to compare the appear-
ance of cracked roots between the experimental groups.
Results: No cracks were found in the control teeth and
teeth instrumented with the Self-Adjusting File. Cracks
were found in 10 of 20 (50%), 7 of 20 (35%), and 1 of
20 (5%) teeth after canal instrumentation with the Pro-
Taper, OneShape, and Reciproc files, respectively. The
difference between the experimental groups was statisti-
cally significant (P < .001). Conclusions: Nickel-titanium
instruments may cause cracks on the apical root surface
or in the canal wall; the Self-Adjusting File and Reciproc
files caused less cracks than the ProTaper and OneShape
files. (J Endod 2013;39:1054–1056)

Abstract
Introduction: Sodium hypochlorite (NaOCl) solutions
with added wetting agents are advertised to dissolve
necrotic tissue in root canals faster than their counter-
parts without a lowered surface tension. This was tested
in the current study, and the null hypothesis formulated
was that there was no difference between a commer-
cially available NaOCl solution with a lowered surface
tension (Chlor-XTRA; Vista Dental Products, Racine,
WI) and a counterpart containing the same amount of
available chlorine without added wetting agents
regarding the soft tissue that remains in oval-shaped
canals after mechanical preparation and irrigation.
Methods: Formerly vital extracted teeth (N = 44, 22
pairs) with similar anatomy were radiographically paired
and chemomechanically prepared. In 1 tooth from each
pair, a 5.25% NaOCl solution with reduced surface tension
was used; in the other, a pure, technical-grade NaOCl solu-
tion of 5.25% was used. The percentage of remaining pulp
tissue (PRPT) was histologically assessed in root cross-
sections. The non-Gaussian raw data were subjected to
Kruskal-Wallis and Mann-Whitney U tests to verify the
respective effect of the cross-section level and solution
on the PRPT. The relationship between the cross-section
level and the PRPT was estimated by the Spearman corre-
lation test. The alpha-type error was set at 5%. Results:
The cross-section level significantly influenced the PRPT
(P < .05), whereas the PRPT was not influenced by the
solution used (P > .05). A significant inverse correlation
was found between the cross-section level and the
PRPT (P < .05, r = 0.330). The lower the distance to
the apex, the higher the PRPT regardless of the solution
used. Conclusions: Contrary to the advertised statement,
the dental solution with a reduced surface tension did not
dissolve vital pulp tissue in oval root canals any better than
a conventional NaOCl solution of similar strength. Closer
to the apex, pulp tissue dissolution is less efficient irre-
spective of the solution. (J Endod 2013;39:1039–1043)

JOE august 2013 - One-Visit Versus Two-Visit Root Canal Treatment: Effectiveness in the Removal of Endotoxins and Cultivable Bacteria
One-Visit Versus Two-Visit Root Canal Treatment: Effectiveness in the Removal of Endotoxins
and Cultivable Bacteria

Abstract
Introduction: This clinical study was conducted to
compare the effectiveness of 1-visit versus 2-visit root
canal treatment in removing endotoxins and cultivable
bacteria from primarily infected root canals. Methods:
Forty-eight primarily infected root canals were selected
and randomly divided into 4 groups: G1, 1% NaOCl; G2,
2% chlorhexidine (CHX) gel; G3, 1% NaOCl + Ca(OH)2;
and G4, 2% CHX gel + Ca(OH)2 (all, n = 12). G1 and G2
involved 1-visit treatment, whereas G3 and G4 involved
2-visit treatment with the placement of Ca(OH)2 medica-
tion for 14 days. Samples were collected before and after
root canal procedures. A chromogenic LAL assay test was
used to quantify endotoxins. Culture techniques were
used to determine bacterial counts. Results: Endotoxins
and cultivable bacteria were detected in 100% of the
initial samples. All treatment protocols were effective in
reducing bacterial load from infected root canals: G1
(1% NaOCl, 99.97%), G2 (2% CHX gel, 99.75%), G3
(1% NaOCl + Ca(OH)2, 99.90%), and G4 (2% CHX gel
+ Ca(OH)2, 96.81%), respectively (P < .05). No differ-
ences were found in bacterial load reduction when
comparing 1-visit and 2-visit treatment groups, irrespec-
tive of the irrigant tested (P > .05). Higher median
percentage values of endotoxin reduction were achieved
in the 2-visit treatment groups (G3, 98.01% and G4,
96.81%) compared with 1-visit treatment groups (G1,
86.33% and G2, 84.77%) (all P < .05). Conclusions:
Both 1-visit and 2-visit root canal treatment protocols
were effective in reducing bacteria and endotoxins, but
they were not able to eliminate them in all root canals
analyzed. Furthermore, 2-visit root canal treatment proto-
cols were more effective in reducing endotoxins than
1-visit root canal treatment protocols.
