Abstract
AimThe aim of the present randomized, double blind, parallel, 2-arm clinical study was to examine the safety and efficacy of frequent applications of chlorhexidine chip (CHX) and flurbiprofen chip (FBP) in patients with chronic periodontitis.MethodsSixty patients were randomized into CHX and FBP groups. Following OHI and scaling and root planing (SRP), baseline pocket depth (PD) measurements, gingival recession and bleeding on probing (BOP) were performed and repeated at week 4 and 8. The assigned chip was placed at weeks 0, 1, 2, 3, 5, 7.ResultsMean PD reduction in the CHX group was 2.08 mm (7.17 to 5.09, p < 0.0001). Mean PD reduction in the FBP group was 2.27 mm (6.72 to 4.45, p < 0.0001). Ninety-seven percentage and 95% of these sites exhibited PD reduction ≥1 mm, while 38% and 34% of the sites exhibited PD ≥3 mm (FBP and CHX, respectively). Clinical attachment level gain (1.66 and 1.95 mm, respectively) was statistically significant (p < 0.0001). Baseline BOP dropped from 98% and 100% to 24% and 30% for the CHX and FBP groups, respectively (p < 0.0001).ConclusionFrequent applications of CHX and FBP chips resulted in a significant improvement in the periodontal condition in these sites. Furthermore studies will be required to compare this new treatment regimen to SRP or SRP with single chip application.
Highlights
Mean baseline pocket depth (PD) was 7.17 ± 0.14 mm and 6.72 ± 0.13 mm for the chlorhexidine gluconate (CHX) and flurbiprofen chip (FBP) groups, respectively, which were very similar to the screening measurements for both groups (7.29 and 6.78 mm, respectively)
Frequent application of CHX and FBP chips together with single session of scaling and root planing (SRP) at baseline resulted in a mean PD reduction of more than 2 mm within 8 weeks in patients with chronic periodontitis
The greater clinical attachment level (CAL) gain in the present study might be associated with the greater intensity of the application of the chips; this in turn results in higher local concentration of the drug that might be responsible for the greater effect
Summary
The aim of the present randomized, double blind, parallel, 2-arm clinical study was to examine the safety and efficacy of frequent applications of chlorhexidine chip (CHX) and flurbiprofen chip (FBP) in patients with chronic periodontitis. The aim of the present study was to explore the efficacy and safety of a new drug (FBP chip) and well-known LDS medication (CHX Chip) using a new, intensive placement protocol
