Abstract

BACKGROUND:

Periapical lesions are inflammatory diseases that result in periapical bone destruction because of host defensive-microbial disturbances.

OBJECTIVE:

To evaluate the role of prophylactic ibuprofen and N-acetylcysteine (NAC) on the levels of tumor necrosis factor alpha (TNF- α), interleukin- 6(IL-6) and IL-17 and post-treatment pain level in chronic periapical lesions.

MATERIALS AND METHODS:

Eighty patients with chronic apical lesions less than 1 cm were randomly assigned to receive NAC tablets (400 mg), ibuprofen tablets (400 mg), NAC (400 mg)/ibuprofen (200 mg) combination and placebo 90 minutes prior to sampling. Periapical exudates were collected from root canals. TNF- α, IL-6 and IL-17 levels were determined by ELISA and post-treatment pain was assessed using a visual analog scale (VAS).

RESULTS:

There was a significant difference in IL-6 level between ibuprofen group and placebo (p = 0.019). Significant difference in IL-17 level was observed between NAC/ibuprofen combination group and placebo (p = 0.043). Four hours after treatment, a significant difference was observed in VAS pain score between ibuprofen group and placebo (p = 0.017). Eight hours post-treatment, VAS pain score for NAC group was statistically lower than placebo group (p = 0.033). After 12 hours VAS pain score showed a significant decrease in NAC group compared to placebo (p = 0.049).

CONCLUSION:

The prophylactic ibuprofen and NAC failed to clearly reflect their effect on cytokines levels in exudates of chronic periapical lesions. On the other hand it seems that NAC can be a substitute for ibuprofen in the management of post endodontic pain.
