Objective:To analyze osteopontin mRNA expression levels in subjects with periodontitis prior to (baseline) and 7, 14, and 28 days following scaling and root planing (SRP). Material and Methods:Gingival crevicular fluid was collected as clinical samples from four subjects with periodontitis (pocket depth, 4-5 mm) aged 35-54 years old as well as from three healthy subjects (controls). The osteopontin mRNA expression levels were measured by quantitative real-time polymerase chain reaction. Spearman’s rank correlation between osteopontin levels in gingival crevicular fluid and the modified gingival index (MGI) was also performed. Results:The Wilcoxon signed-rank test showed no significant difference in osteopontin mRNA expression levels between baseline and 28 days following SRP (p=0.068). The Friedman test showed no significant difference in osteopontin mRNA expression levels between baseline and following SRP (7, 14, or 28 days) (p>0.05). Spearman’s rank correlation showed no significant correlation between osteopontin mRNA expression levels and MGI (r=0.087; p=0.749). Conclusion:Following SRP of periodontal tissue, there was a decreasing trend in osteopontin mRNA expression; however, this finding was not statistically significant. Nevertheless, osteopontin can be used as a biomarker to monitor the healing process; however, further studies are required to clarify our results.
