Details and patient eligibility

About

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.

Enrollment: 194 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Diagnosis of asymptomatic or symptomatic irreversible pulpitis according to AAE consensus. The diagnosis was based on clinical examinations and confirmed upon accessing the teeth.
• Consenting adults age 18 years and older
• Non-contributory medical history (ASA Class I & II)
• Included patients were given oral and written information agreed for participation and signed the informed consent

Exclusion criteria

• Non-consenting patients and patients below 18 years of age
• Medical history with ASA Class III & IV
• Non-restorable teeth
• Teeth with a non-vital pulp
• Periodontal probing depths were more than 4mm
• Pre-medication with antibiotics and/or analgesics 24 hours before the treatment
• Patients taking analgesics routinely for non-dental reasons

194 participants in 2 patient groups

Obturation technique: WVT

Experimental group

Description:

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.

Treatment:

Procedure: Non-surgical root canal treatment filled with WVT

Obturation technique: SBT

Active Comparator group

Description:

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.

Procedure: Non-surgical root canal treatment filled with SBT
