Dental Pulp Disorder clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Monocentric Study and Prognostic of Treatments Endodontics of Teeth With Periapical Pathology Realized CSERD (Nantes University Hospital)

Start date: March 2009
Phase: N/A
Study type: Interventional

Endodontic therapy is to achieve the eviction of the inflamed or infected pulp and fill the canal opening with a hermetic sealing material. The analysis of the literature on intracanal therapeutic shows great variability of the results obtained, the reported success rate is 53 to 95%. This is explained by the difficulty of the surgical procedure, but also by the multiplicity of possible factors of failure, related practitioner, canal anatomy, the operating procedures, the preparation techniques and root canal filling. This success rate is variable depending on the presence or absence of periapical pathology before treatment: more than 85% for teeth treated without initial periapical pathology against only 62% for teeth with pathology before treatment. Furthermore, the literature review revealed two contradictory assumptions about the dominant factor failure in endodontics: the failure of the sealing canal system (bad level shutter) against the failure of the endovascular disinfection. Main hypothesis of the research objectives: The probability of success in a year endodontic treatments carried out according to the recommendations and the operating standards on teeth with periapical pathology is approximately 60%. The primary prognostic factors would be the existence of intracanal obstacles (stop calcification ...) responsible for a sub-obturation of the canal, factors inherent to the tooth (situation ductal anatomy and complexity), the operating techniques used, the practitioner ( skill level), the quality of the restoration.
