About this study

Official title: Assessment of Tooth Retention 10 Years After Root Canal Treatment With Endomethasone N: a Retro-prospective, National and Multicentre Clinical Study

The aim of root canal treatment, or endodontic treatment, is to treat pulpal or periapical diseases and thus transform a pathological tooth into a healthy, asymptomatic and functional entity on the dental arch. The diagnosis of pulp pathology is based on the symptomatology described by the patient, on data from the clinical examination and tests performed as well as the radiographic examinations.

Different families of root canal sealers are used in endodontics: cements based on zinc oxide-eugenol (ZOE), resin-based materials, and calcium silicate-based cements. They provide a stable and hermetic sealing. The Septodont laboratory has developed and manufactured endomethasone N, a zinc oxide-eugenol root canal sealer.

The aim of this retro-prospective PMCF study is to collect long term clinical and safety data on root canal obturation after treatment or retreatment by Endomethasone N.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Endomethasone NDevice

    Endomethasone N is a powder intended to be mixed extemporaneously with a eugenol-based liquid (i.e, Endomethasone Liquid) to obtain a permanent root canal sealer. After selection of dentists, they will screen consecutively and systematically eligible patients, will send them the Patient Information Letter and will enroll them in the clinical investigation if non opposition from the patient. Patient clinical data will be recorded in an electronic Case Report Form. Pseudonymized retro-alveolar radiographies at baseline consultation and at 5 and 10 years post-obturation consultations will be recorded in the e-CRF. These radiographies will be examined by 2 independent endodontists and the results of these examinations will be recorded in the e-CRF. Site data will be collected on a Site Questionnaire with Visual Analog Scales.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Assessment of tooth functional retention

    Rate of tooth functional retention after Root Canal Treatment with Endomethasone N

    Measured: 10 years

Secondary outcomes (7)
  1. Assessment of tooth functional retention

    Rate of tooth functional retention after Root Canal Treatment with Endomethasone N.

    Measured: 5 years

  2. Assessment of the tooth functional retention after Root Canal Treatment with Endomethasone N according to initial treatment or retreatment

    Rate of tooth functional retention after Root Canal Treatment with Endomethasone N according to initial treatment or retreatment, on the basis of the same definition above

    Measured: 5 and 10 years

  3. Assessment of the periapical healing

    The periapical healing (success of obturation with Endomethasone N based on radiological criteria) at 5 and 10 years after Root Canal Treatment, will be evaluated in patients with retro-alveolar radiographs at the follow-up consultation (in parallel of the baseline consultation).

    The periapical healing is defined as follows:

    • a periapical status considered "normal" (PAI score <3) (See Appendix 2)
    • no resorption of the filling cement in the root, detectable on radiography
    • dense and homogeneous filling, limited to the canal,
    • a filling with the maintenance of the canal anatomy

    Measured: 5 and 10 years

  4. The technical characteristics of the sealer Endomethasone N

    The technical characteristics of the sealer Endomethasone N at 5 and 10 years after Root Canal Treatment "Not resorbable once hardened", "Not retractable over the years" and "Radiopaque" will be evaluated in patients with retro-alveolar radiographs at the follow-up consultation (in parallel of the baseline consultation). The technical characteristics are defined as follows:

    • no resorption of the filling cement in the root, detectable on radiography
    • dense and homogeneous filling, limited to the canal, with no apparent void along the root canal walls
    • a filling with the maintenance of the canal anatomy

    Measured: 5 and 10 years

  5. The ease of use and insertion of Endomethasone N in the canal

    The ease of use and insertion of Endomethasone N in the canal will be evaluated with the score obtained on the Visual Analog Scale: score from 0 (Not at all) to 10 (Certainly Yes).

    Measured: 5 and 10 years

  6. The Investigator overall satisfaction of the experience with Endomethasone N

    The Investigator overall satisfaction of the experience with Endomethasone N will be evaluated at 5 and 10 years after Root Canal Obturation with the score obtained on the Visual Analog Scale : score from 0 (Not at all) to 10 (Certainly Yes).

    Measured: 5 and 10 years

  7. The immediate and long-term post-obturation adverse device effects

    The immediate and long-term post-obturation adverse device effects will be evaluated with the list of adverse events immediately appearing after root canal filling and appearing at long-term (5 and 10 years) after root canal filling

    Measured: Immediately after root canal filling, and at long-term (i.e. 5 and 10 years)

Questions about this trial

What is this clinical trial studying?

An observational study of Dental Root Canal Obturation, run by Septodont at 5 sites in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 6 May 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Assessment of tooth functional retention (time frame: 10 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 May 2026.
