METHODOLOGY:

This study is performed only in adults who required a non-surgical root canal obturation. The studied indication is the root canal sealing.

This multi-centre and open-label study comprises two groups corresponding to tested root canal sealer (a reference product and investigational product). Randomization is required.

Investigational product that is a dental cement based on biosilicate technology (PA0903) will be applied with lateral compaction or single cone technique. On the contrary, reference product that is a zinc oxide-eugenol used in dental practice (Pulp Canal Sealer) will be applied with a single wave technique.

Study start: 01/12/11

Inclusion period: 24 months

Study duration: 2 years after the end of inclusion period

OBJECTIVES: The trial objective is to illustrate the clinical and radiographic outcome of PA0903 in the described indication.

Primary objectives:

The primary objective is to evaluate: clinical and radiographic outcome of root canal treatment at two years when using PA0903 as an endodontic sealer with gutta-percha. The success rate is defined as no pain (score of 0 at the VAS scale) and absence or decrease in the size of LEO (fulfilment of Strindberg's criteria). If a pre-existing lesion, the size decrease associated with normal contours, width and structure of the periodontal margines is considered as success. All cases in which lesion increases or is stabilized after 2 years were judged as unsuccessful . Moreover, all cases in which Strindberg's criteria if they are suitable were not fulfilled were judged as unsuccessful. A follow-up of two years is described as the predictive time of success.

Secondary objective:

The secondary objectives are to evaluate the following criteria and in an indicative way, to compare them between patients receiving the PA0903 and those receiving the reference product:

  • The success rate at each time point and also the components of this composite variable (i.e. pain and Healing process for total class (vital teeth and necrotic teeth) of endodontic status of teeth).

In case of pre-existing LEO associated with necrotic teeth, size of LEO and suitable Strindgberg's criteria will be used to judge the outcomes of the root canal therapy as described below :

At visit 2 (6 months) treatment is considered successful when LEO is stable or decreased in comparison with V0 associated with Strindberg's criteria suitable.

At V3 (1 year), treatment is considered successful when LEO is decreased in comparison with V2 associated with Strindberg's criteria suitable.

  • the Healing process associated with PA0903 application in each endodontic status
  • the handling, consistency and physical characteristics of PA0903
  • the longevity and safety of the product associated with PA0903 after two years.

TRIAL POPULATION AND NUMBER OF PATIENTS: about 60 patients will have to be included in the study, 20 by center with a ratio 2 (PA0903): 1 (reference). Adults will be included without gender distinction.

Coordinating center Endodotontic service of Pitié Salpétrière Pitié Salpétrière Hospital 75634 Paris Cedex 13 France

DURATION OF TREATMENT:

The product is applied on D0 (inclusion) of the study. The follow-up period includes 2 years with 4 visits: Visit 1(Week 2), Visit 2 (Month 6), Visit 3 (Year 1) and Visit 4 (Year 2).

What is being measured

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

  1. clinical and radiographic outcome of PA0903 as root canal sealer

    to evaluate clinical and radiographic outcome of root canal treatment at two years when using PA0903 as an endodontic sealer with gutta-percha. The success rate is defined as no pain (score of 0 at the VAS scale) and absence or decrease in the size of LEO (fulfilment of Strindberg's criteria). If a pre-existing lesion, the size decrease associated with normal contours, width and structure of the periodontal margines is considered as success. All cases in which lesion increases or is stabilized after 2 years were judged as unsuccessful .A follow-up of two years is described as the predictive time of success.

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

A study testing Pulp Canal Sealer (Kerr) and PA0903 in people with Root Canal Obturation, run by Ascopharm Groupe Novasco at 3 sites in 2 countries.

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 10 inclusion and 23 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

clinical and radiographic outcome of PA0903 as root canal sealer (time frame: 2 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?
