NCT04885686

Brief Summary

The study is a post-marketing performance and safety study, designed as a comparative, prospective, multicenter, simple-blind, randomized clinical trial. 300 subjects requiring a primary or a secondary root canal treatment will be enrolled in 2 groups (150 in each group). The aim of the study is to demonstrate the superiority of the hydrocortisone-containing root canal sealer Endomethasone N RCS, compared to the hydrocortisone-free root canal sealer Endomethasone SP RCS, with regard to reduction of the maximum post-operative spontaneous pain during the 7 days following the root canal treatment. Root canal treatment procedures will be in accordance with the allocation by randomisation of Endomethasone N RCS or Endomethasone SP RCS. The spontaneous and the Masticatory pain will be record at predefined times, a phone call will be done at 48h and a visit will be realized at day 7 (max Day 14).

Outcome Measures

Primary Outcomes (1)

  • Maximum post-operative pain using a visual analogue scale (VAS : 0-100)

    The pain is assessed by patients in a diary using a Visual Analogue Scale (VAS: 0-100 mm; 0 no pain - 100 maximum pain) at different times after endodontic treatment (at the end of the root canal obturation, 3h, 6h 12h, 24h, Day 2, Day 3, Day 4 Day 5, Day 5, 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 Outcomes (7)

  • Spontaneous pain intensity

    from the end of the root canal treatment (Day 0) to Day 7

  • Occurrence of spontaneous pain flare-ups

    From Day 3 to Day7

  • Masticatory pain intensity

    from the end of the root canal treatment (Day 0) to Day 7

  • Maximum Masticatory pain intensity using a visual analogue scale (VAS : 0-100mm)

    from the end of the root canal treatment (Day 0) to Day 7

  • Use of oral pain treatment

    from the end of the root canal treatment (Day 0) to Day 7

  • +2 more secondary outcomes

  • Other dental treatment ongoing or scheduled within the study period;
  • At least one symptomatic tooth among those that are not included in this study
  • Known hypersensitivity to steroids, local anesthetics, or any component of study medical devices;
  • Subject using long term anti-inflammatory drugs;
  • Use of illicit substances during the 48h before the first visit (cannabis, cocaine…);
