Pulpotomy vs Root Canal Treatment for Teeth With Symptomatic Irreversible Pulpitis
Pulpotomy vs Root Canal Treatment for Teeth With Symptomatic Irreversible Pulpitis
This study is a randomised controlled trial for complete pulpotomy as an alternative to root canal treatment for teeth with clinical diagnosis of symptomatic irreversible pulpitis (i.e. signs and symptoms indicative of irreversible pulpitis) conducted at the National University Centre for Oral Health Singapore (NUCOHS) Endodontic unit. Up to 70 teeth, 35 in each group, will be enrolled.
Clinical and radiographic outcome data will be collected and analysed, and a parallel cost-effectiveness analysis will also be undertaken to examine the potential costs and benefits of pulpotomy. A process evaluation will also be conducted to assess the acceptability of the intervention to both dentists and patients, while exploring the barriers and enablers to implementation.
Mature permanent teeth with deep caries/restorations and symptoms indicative of irreversible pulpitis (moderate to severe spontaneous lingering pain) will be included in the study. The teeth will be randomised to receive one of two treatments: RCT or complete pulpotomy (n=35 in each group).
Baseline clinical and radiographic data will be collected at the first visit. In addition, patients (or their guardians, if relevant) will be invited to complete the acceptability and willingness to pay questionnaires for health economics analysis at both the first visit and at 12 months from the date of completed treatment. Pain data will be collected via a pain diary after completion of treatment at days 3 and 7 post-treatment. Patients will be clinically and radiographically reviewed at 6 and 12 months from the date of completed treatment. Review clinical data collected will include the absence of pain (and details on the nature of pain, if relevant), tenderness to percussion and palpation, presence of a swelling or a sinus tract, pathological mobility, structural integrity of tooth, intact and non-defective restoration, and response to electric pulp testing (for the pulpotomy group only). Radiographic data collected will include the presence of periapical radiolucency, presence of inter-radicular radiolucency, presence of resorption, and presence of calcifications. The need for any further intervention (including details of any procedure) or any adverse events or unscheduled visits over the follow-up period will also be recorded.
Success will be defined as 1) the absence of pain indicative of irreversible pulpitis, 2) the absence of signs and symptoms indicative of acute or chronic periapical disease, and 3) the absence of radiographic evidence of failure including radiolucency or resorption. SPSS Statistical Package (IBM SPSS Statistics) will be used for all statistical analysis, with the significance level for all statistical tests set at p-value<0.05.
