Post-operative Pain, Apical Periodontitis
About this trial
This is an interventional treatment trial for Post-operative Pain focused on measuring diode laser, EDDY, post-operative pain, sypmtomatic apical periodontitis
Eligibility Criteria
Inclusion Criteria:
- Healthy adult patients aged between 18 and 65 years
- Moderate to severe pain (4-10) according to a visual analogue scale (VAS)
- Mandibular molar teeth diagnosed with symptomatic apical periodontitis (a painful response during mastication and/or percussion or palpation)
Exclusion Criteria:
- Pregnancy or lactation
- Taking analgesics or anti-inflammatory drugs 12 hours before the treatment
- Taking antibiotics in the month prior to the treatment
- Teeth with calcified root canals, greater than grade I mobility and a 4 mm pocket depth, non-restorable damage, occlusal trauma and previous root canal treatment or an open apex
- Allergy to articaine or non-steroid anti-inflammatory drugs
Sites / Locations
- Biruni University

Group 4 (EDDY and laser irradiation)
After finishing the mechanical instrumentation, each root canal was irrigated with 5 ml of 5.25% NaOCl using a 31-gauge needle positioned 2 mm shorter than the WL. To remove the smear layer, 5 ml of 17% ethylenediaminetetraacetic acid (EDTA) was used in each canal for 1 minute, and 5 ml of saline was then administered to neutralize all the residues.
In group 2, 1 ml of 5.25% NaOCl was agitated for 20 seconds three times with the EDDY tip positioned 2 mm shorter than the WL. The root canals were then irrigated with 2 ml of 5.25% NaOCl again. Subsequently, the EDDY tip was activated with short pumping movements, and 2 ml of 17% EDTA was activated for 30 seconds, as described above. The final irrigation followed the same procedures as in group 1.
In group 3, final irrigation followed the same procedures as in group 1 and group 2. During the laser therapy, both the operator and the patient wore eyewear for protection. Laser irradiation was performed using a 980-nm diode laser (Medency Primo 10 W Diode Laser; Vicenza, Italy), coupled with optical fibre (200 µm). The settings were as follows: average power of 1.2 W with a low frequency of 50 Hz and energy of 12 J (each cycle) in pulsed mode, irradiation for 10 seconds, followed by a 10 second pause, which constituted one cycle. This cycle was applied four times to each root canal. The optical fibre tip was located at the WL. The root canals were then slowly (at a speed of 2 mm/s) irradiated from the apical to the coronal portion using a continuous helicoidal movement, with optical fibre tip contacting the root canal walls in one cycle for each power.
In this group, after agitation using the EDDY (VDW) system was performed using the same procedures as in group 3, final irrigation and laser irradiation were done as in group 2.
