Purpose: To compare the success rates of teeth with three different root end materials (Amalgam, SuperEBA and IRM)
N= 488 cases.
Materials and methods:
•The sample was collected from two private endodontic clinics.
•All patients that had apicectomy with a retro-grade filling in the past 10 years
•Radiographs taken at the completion of surgery and the last recall ( minimum 6 months recall )
•a) Healed lesion in which complete regeneration of PDL demonstrated radiographically
•b) Tendency to heal when the lesion decreased in size but still present •Failure: Lesions that increased in size or remained the same.
•Teeth with VRF and periodontal failures were eliminated from the study
Most highlighted results:
•The success rate for amalgam was 75%
•The success rates for SuperEBA and IRM were 95% and 91% respectively.
With the presence of SuperEBA and IRM as retrograde filling materials, amalgam should not be considered as a material of choice.
