Post-endodontic Pain Survey

Not Applicable

Completed

• Conditions: Endodontic Disease; Postoperative Pain; Obturation
• Interventions: Procedure: Non-surgical root canal treatment filled with WVT; Procedure: Non-surgical root canal treatment filled with SBT

• Registration Number: NCT04462731
• Lead Sponsor: Ya-Hsin Yu, DDS, MS

Brief 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. Postoperative pain after one-visit root-canal treatment on teeth with vital pulps: Comparison of three different obturation techniques.

• Medical history with ASA Class III & IV
• Non-restorable teeth
• Teeth with a non-vital pulp
• Periodontal probing depths were more than 4mm

Arm && Interventions

Group	Intervention	Description
Obturation technique: WVT	Non-surgical root canal treatment filled with WVT	Warm vertical compaction technique (WVT): Teeth filled with AH Plus Jet Root Canal Sealer were filled with .04 taper gutta-percha points by WVT. The sealer was introduced with the master cone. The depth of heated plugger was within 3-5 mm of WL in the WVT group, and the remaining canal space was backfilled with additional sealer and thermoplasticized gutta-percha.
Obturation technique: SBT	Non-surgical root canal treatment filled with SBT	Sealer-based filling technique (SBT): Teeth filled with SBT were obturated with EndoSequence BC Sealer by injecting the sealer into the coronal third of each canal. Size 30 Lentulo spiral coated with additional sealer was introduced 3 mm short of WL depth at 300rpm. Bioceramic coated gutta-percha was dipped in BC sealer and introduced into the canal to WL. A heated plugger was used to sear the gutta-percha point at each orifice.

Primary Outcome Measures

Name	Time	Method
Visual Analogue Scale (VAS)	4-, 24-, and 48-hour after receiving root canal treatment	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.
