Clinical Trial Summary

As part of root canal treatment, canals should be sealed to prevent further contaminations. There are multiple accepted techniques to fill-obturate canals. In the past, different obturation techniques have been compared. The most current technique used, a single cone with bioceramic sealer, has not been compared. This clinical investigation will compare the postoperative pain of this technique to another common technique used in our clinic.

Intervention

Procedure:
• Non-surgical root canal treatment filled with WVT
All eligible teeth were isolated with a rubber dam during root canal treatment. The procedures were performed under a microscope (OPMI Pico; Carl Zeiss, Gottingen, Germany). After access, location of canals, and determination of working length (WL) with Root ZX II apex locator (J Morita, Kyoto, Japan), the canals were instrumented using various .04 taper rotary NiTi instruments to a minimum apical size of 35. 4% Sodium hypochlorite was used as the main irrigant with a 31-gauge needle. 17% EDTA was used as the final irrigant. Passive ultrasonic irrigation with size 20 Acteon tip inserted 2mm short of WL was performed with both 4% sodium hypochlorite and 17% EDTA for 10 seconds in each canal. After final irrigation, the canals were dried with paper points. The master gutta-percha cone fit was verified with periapical radiographs before filling the tooth. WVT was used to fill the tooth when the months were January, March, May, July, September, and November.
• Non-surgical root canal treatment filled with SBT
All eligible teeth were isolated with a rubber dam during root canal treatment. The procedures were performed under a microscope (OPMI Pico; Carl Zeiss, Gottingen, Germany). After access, location of canals, and determination of working length (WL) with Root ZX II apex locator (J Morita, Kyoto, Japan), the canals were instrumented using various .04 taper rotary NiTi instruments to a minimum apical size of 35. 4% Sodium hypochlorite was used as the main irrigant with a 31-gauge needle. 17% EDTA was used as the final irrigant. Passive ultrasonic irrigation with size 20 Acteon tip inserted 2mm short of WL was performed with both 4% sodium hypochlorite and 17% EDTA for 10 seconds in each canal. After final irrigation, the canals were dried with paper points. The master gutta-percha cone fit was verified with periapical radiographs before filling the tooth. SBT was used to fill the tooth when the months were February, April, June, August, October, and December.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Visual Analogue Scale (VAS)	Patients were asked to rate the intensity of preoperative pain on a visual analogue scale (VAS) from 0 (no pain) to 10 (worst pain ever) before receiving root canal treatment. At the end of the visit, the patients were given a survey and asked to rate the intensity of postoperative pain (VAS 0-10) at 4 hours, 24 hours, and 48 hours after the procedure.	4-, 24-, and 48-hour after receiving root canal treatment
