Brief Summary

The aim of this study is to evaluate the clinical effectiveness of total pulpotomy (TP), radicular pulpotomy (RP), and root canal treatment (RCT) in mandibular premolar and/or molar teeth diagnosed with symptomatic irreversible pulpitis, with respect to postoperative pain control and treatment success.Materials and Methods:A total of 99 mandibular premolar and molar teeth will be included in this study. The teeth will be randomly allocated into three groups (n = 33 per group): total pulpotomy, radicular pulpotomy, and root canal treatment.Root canal treatment will be performed using standardized endodontic protocols.Total pulpotomy will be carried out to the level of the canal orifices, followed by hemostasis achieved with 2.5% sodium hypochlorite (NaOCl). A 3-mm-thick layer of mineral trioxide aggregate (MTA) will be placed as the pulpotomy material.Radicular pulpotomy will be performed by removing the pulp tissue a few millimeters apical to the canal orifices. Hemostasis will be achieved using 2.5% NaOCl, and a 3-mm-thick layer of MTA will be placed as the pulpotomy agent.All treated teeth will be restored with glass ionomer cement, followed by a composite resin restoration.Postoperative pain intensity will be assessed using a visual analog scale (VAS) at the following time points: preoperatively, and at 12 hours, 24 hours, 48 hours, and 7 days postoperatively. Clinical and radiographic evaluations will be performed at 3, 6, and 12 months to assess treatment success and periapical health.

Outcome Measures

Primary Outcomes (2)

  • Periapical healing

    Radiographic periapical status will be assessed using the Periapical Index (PAI) according to Ørstavik et al., with scores ranging from 1 (normal periapical structures) to 5 (severe apical periodontitis), based on the degree of periapical radiolucency. The primary outcome will be periapical lesion healing, evaluated by changes in periapical index (PAI) scores on periapical radiographs taken before treatment and at the 12-month follow-up.

    1 year

  • Post-operative pain

    Pre-operative and post-operative pain scores were determined according to the Heft-Parker Visual Analog Scale (HP VAS), which consisted of a 10 mm long horizontal line where numerical values were divided into visual categories. Patients were instructed to score their pain with a value on the HP VAS. The presence or absence of pain was classified according to 4 categories: No pain (level 1, 0), Mild pain (level 2, 1-3 mm), Moderate pain (level 3, 4-6mm), Severe pain (level 4, 7-10 mm).

Study Arms (3)

Total Pulpotomy

EXPERIMENTAL

After the access cavity is prepared, the vitality of the pulp will be visually confirmed. The coronal pulp tissue will be removed using a high-speed sterile diamond bur with copious water cooling. A cotton pellet moistened with 2.5% NaOCl will be applied to the pulp chamber. If necessary, this procedure will be repeated for up to 10 minutes. The time required to achieve hemostasis will be recorded.

Procedure: Total Pulpotomy

Radicular Pulpotomy

EXPERIMENTAL

Inflamed coronal pulp tissue will be removed using a large sterile round bur on a high-speed handpiece with air-water spray, down to the level of the canal orifices. The canal orifices will be located, and the depth of the pulp chamber will be measured using a Williams probe. A sterile long-shank round carbide bur will be marked with an endodontic file stopper (pulp chamber depth + 3 mm), and radicular pulp tissue will be removed from the canal orifice level to approximately 2-3 mm apical depth. Small cotton pellets moistened with 2.5% NaOCl will be individually placed into each canal orifice, down to the level of pulp excision; if necessary, the procedure will be repeated for up to 10 minutes. The time required to achieve hemostasis will be recorded.

Procedure: Radicular pulpotomy

Root Canal Treatment Procedure

ACTIVE COMPARATOR

After the access cavity is prepared, the vitality of the pulp will be visually confirmed. Once the canal orifices are located, the working length (WL) will be determined using a No. 10 K-file and an apex locator, and then confirmed radiographically. Chemomechanical preparation will be performed to the working length using Reciproc files. After every three pecking motions, the root canals will be irrigated with 2.5% NaOCl. The final irrigation sequence will be as follows: * 5 mL of 17% EDTA for 1 minute * 5 mL of distilled water * 5 mL of 2.5% NaOCl maintained in the canal for 1 minute * 5 mL of distilled water (to neutralize NaOCl) After irrigation, canals will be dried with sterile paper points and obturated in a single visit using a calcium silicate-based sealer.

Procedure: Root canal treatment
