Clinical Trial Summary

The study design is a multicentric randomized controlled non-inferiority trial. 160 subjects (teeth) requiring a primary or a secondary root canal treatment will be enrolled in 2 groups (80 in each group). The aim of the study is to assess the efficacy rate and the safety 2 years after root canal obturation undertaken using a ready-to-use calcium silicate sealer (PA1704) compared to the control calcium silicate sealer BioRoot™ RCS.

Procedures of root canal treatment will be conventional and standardized for all investigational centers. The canals will be cleaned, shaped and then obturated using a calcium silicate sealer (the ready to use sealer PA1704 or BioRoot™ RCS) with a single cone technique or cold lateral condensation of gutta-percha. Follow-up assessments will be conducted at 6, 12 and 24 months in both groups. The performance and safety of the sealer PA1704 will also be evaluated at 3.5 and 5 years after surgery. Retroalveolar radiographs will be taken at each study visit. The preoperative, postoperative and follow-up clinical and radiographic data will be analyzed.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Efficacy rate of root canal obturation	Efficacy rate of root canal obturation using clinical and radiological criteria. The radiographic criterion will be assessed by blinded evaluators. The efficacy rates will be compared between the 2 groups.	24 months post-treatment
Secondary	Efficacy rate of root canal obturation	Efficacy rate of root canal obturation using clinical and radiological criteria. The radiographic criterion will be assessed by blinded evaluators. The efficacy rates will be compared between the 2 groups at 6 and 12-months post-treatment.; The efficacy rate after 3.5 and 5 years will measured only in the PA1704 group.	6-, 12-months, 3.5 and 5 years post-treatment
Secondary	Radiological evaluation of the canal obturation	Radiological evaluation of the level of apical obturation and density	baseline, 6-, 12-, 24-months, 3.5 and 5 years post-treatment
Secondary	Postoperative pain	The pain is assessed by patients in a diary using a Visual Analogue Scale (VAS: 0-100 mm) at different times after endodontic treatment (at the end of the root canal obturation, 12h postoperative, 24h, Day 2, Day 3, Day 7). The maximum pain felt will be compared between the 2 groups.	from the end of the root canal treatment (Day 0) to Day 7.
Secondary	Use of oral pain treatment	Patients reported the consumption of analgesic treatment in a diary. The proportion of patients who took oral pain medication and the treatment categories will be compared between the 2 groups.	from the end of the root canal treatment (Day 0) to Day 7
Secondary	Adverse events	Adverse events reported by patients on a diary from Day 0 to Day 7 and adverse events clinically observed by the dental surgeon at each follow-up visit will be used to assess the safety of root canal sealers and endodontic procedures	from the end of the root canal treatment (Day 0) to 5 years
