- Evaluate outcome of pulpectomy in 2 treatment sessions with calcium hydroxide as an intracanal dressing was compared to a procedure comprising instrumentation and root-filling in 1 session.
- N= 256 patients from 2 practices in Italy. Included only vital pulps.
- Patients were randomly assigned to one of 2 groups: 1 or 2 visit RCT. Patients were followed up at 1 week for painful symptoms and at 1-3 yrs for signs of apical periodontitis and radiographic healing.
- 244 patients recalled
- 17 teeth had PARL at recall
- Evenly distributed between the 2 groups
- Post-op pain at 1 week associated with overfill
- No association with presence of overfilling and radiographic lesion at end point of recall.
2 visit RCT does not increase success in vital teeth, but overfill is strongly associated with post-op pain.
