To compare post op pain with conventional irrigation vs EndoVac
Single operator (endodontist) in private practice. Duration: 25 months. Effort made to standardize clinical endodontic procedure as much as possible. Same volume of irrigant used for both groups – 2.5% NaOCl, 17% EDTA. Patient given eight 200mg ibuprofen tablets to take for pain prn.
(1) Patient questionnaire for pain evaluation – Borg scale 1-10
(2) Frequency and quantity of analgesic use
Data collected for times points at 4, 24, 48 h after tx
1.Significantly less overall pain associated with EV group.
2.Significantly less analgesic consumption between 0-4 h in the EV group. No statistically significant difference in analgesic consumption at 24 or 48 h.
1.Reasons for post op pain can be mechanical, chemical, or microbial. Study tried to minimize other confounding variables with inclusion criteria.
2.EndoVac shown to decrease post-op pain vs conventional irrigation.
