Comparative Evaluation of Post Endodontic Pain Following Root Canal Treatment With Two Rotary System: Neolix & Waveone
Today, dentists tend to use rotary systems. Despite the increasing diversity of these systems as well as a few studies on the prevalence of pain after root canal treatment by rotary systems, And in particular, comparing the amount of pain after treatment, between systems RECIPROCAL AND FULL ROTATION single-file, the aim of this study was to evaluate the effect of applying canal preparation by the system, Neolix and WaveOne, on the prevalence of pain after endodontic treatments.
Many studies of pain after root canal treatment experience were taken into consideration.
Pain after endodontic treatment is still one of the major problems of patients. The
prevalence that widely studied as 6/10% to 9.82% have been reported.
One of the important strategies in endodontic treatment, prevention and control of pain
after treatment. This multi-factorial disorder resulting in a complex process occurs, which
affects the patient's intrinsic factors, the tooth and the dentist's skill.
Mechanical factors include channel instrumentation techniques, over instrumentation or
filling material extrusion channels associated with the presence of pain after treatment
were considered.
Apical extrusion of infected debris during instrumentation channel can create or exacerbate
inflammatory process. Channel shaping the apical debris extrusion process can increase even
if the preparation is limited to the channel. Leaving debris in both methods of preparation,
either manually with stainless steel files and rotary technique with nickel titanium files
happen.
The use of rotary technique among dentists has increased. developing of NITI files and
rotary instrumentation system, reduce apical extrusion of debris, so can be expected to
reduce the incidence of inflammation and pain after treatment, achieved by these means.
Recent studies have shown that reciprocal shaping techniques, compared with full-rotation
techniques, significantly increased the amount of debris extruded from the apical region of
the root are causing increasing pain after treatment.
Two rotary system available on the market are:
1) Neolix (france Neolix SAS) recently introduced the file NITI, single file, with full
rotation movements, with square and rectangular cross-section, with a non-uniform shape
along the blade, tip sizes, 25 and Tipper 0 / 08, and a system, Wave one, (DENTSPLY
Maillefer), which is a file NITI, Single file and Single use, and the reciprocation
movements, and cross-Convex triangular Modified and in three sizes: small, primary (tip size
25 and Tipper 0/08), large is contained, which according to the size of the canal, one of
them is selected.
In a study by Ana Arias et al., Patients in the experimental group by the Rotary Files roots
were treated and patients in control group were treated by the step-back technique, the
results showed that more patients in the control group, experienced pain after root canal
therapy. While the duration of the pain in the control group comparison to the experimental
group, less has been reported.
In a study by Aqrabawi, teeth with vital pulp were divided into two groups. Root canal
therapy in the first group, was done by manual file, and the second group, by Protaper
rotary files were performed.
And no significant difference in pain after root canal treatment has not been detected.
Gambarini was shown in the study, patients treated by waveone system they have done,
significantly more pain after treatment compared to TF and TF adaptive experienced.
Today, dentists tend to use rotary systems. Despite the increasing diversity of these
systems as well as a few studies on the prevalence of pain after root canal treatment by
rotary systems, And in particular, comparing the amount of pain after treatment, between
systems RECIPROCAL AND FULL ROTATION single-file, the aim of this study was to evaluate the
effect of applying canal preparation by the system, Neolix and WaveOne, on the prevalence of
pain after endodontic treatments.
