Dental Pulp Disorder Clinical Trial
Official title:
Monocentric Study and Prognostic of Treatments Endodontics of Teeth With Periapical Pathology Realized CSERD (Nantes University Hospital)
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.
