Abstract
Objective
The aim of this study was to evaluate the effect of calcium hydroxide (Ca[OH]2) and chlorhexidine (CHX) gel on matrix metalloproteinase-9 (MMP-9) and vasoactive intestinal peptide (VIP) secretion in periapical lesions.
Materials and methods
A total of 60 patients were randomly divided into two groups that were to receive different medications. Pre-and post-treatment samples were collected from the interstitial fluid of periapical lesions using sterile paper points. VIP and MMP-9 levels were measured by enzyme-linked immunosorbent assay kits, and the data were statistically analyzed.
Results
Gender and smoking habits had no effect on the pre- and post-treatment VIP and MMPs levels. Intragroup analyses revealed that in the Ca(OH)2 group, the post-treatment VIP level was found to be significantly higher than the pre-treatment VIP level. In the CHX group, the post-treatment MMP-9 level was significantly higher than the pre-treatment MMP-9 level.
Conclusion
According to the results of the present study, the type of the medication affected the amount of periapical VIP and MMP-9 secretion.
Clinical relevance
VIP is a neuropeptide that promotes new bone formation. Thus, intracanal Ca(OH)2 medication may accelerate the repair process of bone tissue.
