Post-obturation pain is one of the primary problems following
root canal treatment. Although in most cases pain does not last
long, but could be a source of embarrassment to the dentist and
annoying for the patient.
This study was conducted to in
vestigate and compare the
incidence of postoperative pain after one-visit root canal
treatment (RCT) on teeth with vital pulps using three different
obturation techniques.
90 cases were assigned into three treatment groups, each group
30 cases(10 anterior, 10 premolar, 10 molars), The canals of all
teeth were prepared using Protaper rotary system and then filled
at the same visit using one of the three obturation techniques
(lateral condensation technique, HEROFILL technique, E&Q
PLUS technique). The postoperative pain was recorded on a
visual analogue scale (VAS) of 0 - 100 after 2 hours, 24 hours,
48 hours and 7 days.
The specimen consists of 72 extracted teeth with curved roots
(15-35)degree . They were cleaned and preserved in formalin
for 48 hours. Each tooth was mounted in a self curing acrylic
block. The samples were divided into three groups. Each
group
(24 canals) was instrumented with one of the systems
(WaveOne, Reciproc, OneShape).
Objective: the Purpose of this study was to evaluate in vitro the
apical microleakage of methacrylate risen-based sealer (EndoREZ )
after root canal irrigation with sodium hypochlorite or chlorhexidine
digluconate.
Aim of the study was To Compare the efficiency of R
ProTaper and R-Endo retreatment files in the removal of
conventional gutta-percha and resin coated gutta-percha and
time required. 60 extracted single root premolars were selected,
and then divi
ded into two groups according to the obturation
material. Next, each group was divided into two groups
according to the methods of retreatment.
One aim of the root canal treatment is providing compact
three dimensional seal for the canal system to prevent germs
enter and its products across both the apical and coronal
ways.
Gutta-Percha is the most use material to fill the radicalism
ca
nals. It has limited importance in spite of many
specifications as lack of the link to the ridge canal.
