NCT04757753

Brief 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 Measures

Primary Outcomes (1)

  • Efficacy Rate of Root Canal Obturation

    Efficacy rate of root canal obturation using clinical and radiological criteria. A successfull treatment is defined in this study, based on some loose criteria, as: a functional tooth with no lesion on the radio, or a functional tooth with a size reduction of the lesion on the radio, or a functional tooth with a lesion size stabilisation.

    24 months post-treatment

Secondary Outcomes (5)

  • Efficacy Rate of Root Canal Obturation

    12 months post-treatment

  • Efficacy Rate of Root Canal Obturation

    6 months post-treatment

  • Radiological Evaluation of the Canal Obturation

    24-months post-treatment

  • Postoperative Pain

    Before endodontic treatment*; before session#2 initiation**; T0 (after canal obturation); 12; 24; 48; & 72h; 7 days after endodontic treatment. *Evaluation on same day for 1-session treatment; up to 18 days before if 2 sessions needed. **On same day.

  • Use of Oral Pain Treatment

    From Day 0 to Day 7

  • Endodontic treatment on tooth with calcified root canal assessed radiographically,
  • Endodontic treatment on tooth with suspected perforation,
  • Patient with an uncontrolled systemic disease such as diabetes or thyroid disorders, or with an immunocompromised condition or who has undergone radiation therapy to the jaw.
  • Patient suffering from uncontrolled active periodontitis, not supported
  • Participation to another interventional clinical study at the same time,
  • Vulnerable subjects referred to in articles L.1121-5 to 8 and L.1122-1-2 of the Public Health Code and article 66 of Regulation (EU) 2017/745 on medical devices are excluded from the investigation (such as known pregnancy or lactation, patients with legal protection).
