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

Not Applicable

Completed

• Conditions: Dental Pulp Disorder
• Interventions: Other: Endodontic treatment

• Registration Number: NCT02819258
• Lead Sponsor: Nantes University Hospital

Brief Summary

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.
