Purpose:
To compare post op pain with conventional irrigation vs EndoVac
Materials/Methods:
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.
Evaluation criteria:
(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
Results:
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.
Clinical Significance:
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.
