Brief Summary

Background The European Society of Endodontology (ESE) and the American Association of Endodontists (AAE) position statements on the management of deep caries and exposed pulp recommended adoption and promotion of strategies aimed at preserving the pulp, but also acknowledged the need for well-designed and adequately powered randomised control trials to provide the evidence needed to support vital pulp treatment (VPT) and change clinical practice.

Objectives

1. To undertake a randomised controlled clinical trial comparing full pulpotomy with root canal treatment for mature maxillary and mandibular posterior teeth with signs and symptoms indicative of irreversible pulpitis and normal apical tissues in adults.

2. Undertake a cost-effectiveness analysis to examine the potential long-term costs and benefits of pulpotomy.

3. Undertake a process evaluation to assess the acceptability of the intervention to both dentists and patients, while exploring the barriers and enablers to implementation.

Conditions

Pulpitis - Irreversible

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: DOUBLE

Study Groups

Root canal treatment (Control)

The procedure can be carried out in single or two visits. Variations in root canal treatment protocols however will make it difficult to compare with pulpotomy so the aim is to standardize the protocols for the following variables including use of rubber dam, Irrigation protocol with 2-2.5% sodium hypochlorite; working length with combined radiographs and apex locators, automated instrumentation to accompany hand instrumentation and preparation to apical size 2-3 larger than the initial binding file. Canal to be medicated with non-setting calcium hydroxide if done in two visits and root canal filling with gutta percha and traditional sealers (warm or cold lateral condensation) and good coronal seal.

Group Type: OTHER

Root canal treatment (Control)

Intervention Type: PROCEDURE

Root canal treatment - Removal of the inflamed pulp tissues from the whole root canals of the tooth.

Full pulpotomy

The clinical procedure will be completed over one or two visits. Following adequate anesthesia and isolation with rubber dam, access to the pulp will be gained following caries removal to de-roof the pulp chamber and excision of the entire coronal pulp. The pulp chamber is irrigated with 2% sodium hypochlorite solution and the resultant bleeding from the remaining pulp will be controlled with a cotton pellet soaked in 2% sodium hypochlorite solution. Following complete haemostasis, the pulp stump will then be covered with Biodentine (Septodont Ltd., Saint Maur des Fausse ́s, France) and the tooth permanently restored with a restoration if treatment is completed in single visit or temporized with glass ionomer cement for the final restoration to be placed in the 2nd visit if operator opted for 2-visit treatment.

Group Type: EXPERIMENTAL

Full pulpotomy (Experimental)

Intervention Type: PROCEDURE

Full pulpotomy - Removal of the inflamed coronal pulp tissues from the crown of the tooth.

Eligibility Criteria

Inclusion Criteria

• Patients aged 12 years or older (with a mature permanent tooth demonstrating radiographic evidence of a deep caries/restorations and signs/ symptoms indicative of IRP (moderate to severe spontaneous lingering pain). Tooth will be responsive to cold and EPT sensibility testing, restorable and can be adequately isolated during treatment. One posterior tooth (molar or premolar) only per patient.

Exclusion Criteria

• Teeth with active periodontal disease (pocket depth >5mm); teeth indicated for elective root canal treatment for restorative purposes, teeth with apical periodontitis, patients with complex medical histories that may affect their caries experience and healing ability (immunocompromised, radiotherapy), patients who are unable to consent; history of previous trauma to the tooth, presence of apical radiolucency and patients who are pregnant or breast-feeding. Intraoperatively, any evidence of purulence or excessive bleeding that cannot be controlled with a cotton pellet with 2-4% hypochlorite for 10 minutes will be excluded.

• Minimum Eligible Age: 12 Years
• Eligible Sex: ALL
• Accepts Healthy Volunteers: Yes
