Purpose: To compare the long-term clinical outcomes of teeth obturated with Resilon/Real-Seal (RS) and teeth obturated with GP/AH Plus.
n= 100 teeth, RS:50; GP:50
- Teeth with initial RCT from 2007-2012 with no PARL were included
- Recall for RS was 5.8 years and GP was 6.6 years.
- Success was achieve by the lack of clinical S&S and normal PA tissue(evaluated by 3 examiners using image J software to quantify the PARL of failed cases)
Most highlighted Results:
- Success rate of teeth obturated with RS was 56% and 88% with GP.
- Teeth obturated with RS were 5.7 more likely to fail when compared to GP.
- The area of PARL did not differ significantly between the two groups.
- No association was found between outcome and patient age, gender, preoperative diagnosis, or one versus multiple visits.
- PARLs in the failed RS cases tended to be associated with root resorption involving more than 1 root Fig. 1.
Teeth obturated with RS had a 5.7 times greater chance of failure compared with teeth obturated with GP.
