Pengaruh Aplikasi Topikal Chlorhexidine Gel dan Chlorhexidine-Sodium Fluoride Gel terhadap Akumulasi Plak dan Gingivitis akibat Pemakaian Alat Orthodontik Cekat (Kajian pada pasien usia 11-14 tahun di rsgm prof. Soedomo klinik kedokteran gigi anak)

Abstract

      Orthodontic fixed appliances may increased plaque accumulation on the tooth surface and lead gingivitis. Both can be inhibited chemically by topical drug application. The purpose of this study was to determine the effect of topical application of chlorhexidine gel and chlorhexidine-sodium fluoride gel on plaque accumulation and gingival inflammation caused by the use of fixed orthodontic appliances on children.
      A Quasi-experimental with pre test-post test control group research design was performed on 12 children aged 11-14 years who were being treated orthodontics with Roth bracket in 42nd days. Subjects were divided in 2 groups, the first group received chlorhexidine gel application and the second received chlorhexidine-sodium fluoride gel application. The plaque accumulation data was assessed by Orthodontic Plaque Index (OPI), and the gingivitis was assessed by the Gingival Index (GI) and volume of gingival crevicular fluid (GCF). The data were taken 4 times, namely before drug application, 4 days, 8 days and 15 days after drug application. Data were analyzed by multivariate ANOVA, paired and independent sample t-test with 95% of confidence level.
      The results showed that both chlorhexidine gel and chlorhexidine-sodium fluoride gel could significantly reduce OPI, GCF volume and GI based on observation time. However, the chlorhexidinesodium fluoride gel showed a significant decline over OPI in 8 days after  drug application, while chlorhexidine gel after 15 days. A significant decrease in gingivitis signed by GCF volume and GI occurred after 4 days of drug application of chlorhexidine-sodium fluoride gel.
       It was concluded that the use of chlorhexidine gel and chlorhexidine-sodium fluoride gel can reduce the accumulation of plaque, GCF volume, and GI, but the combination of chlorhexidine-sodium fluoride gel was faster in reducing plaque accumulation and gingivitis.
