Latar Belakang: Kerusakan jaringan periodontal terjadi karena inflamasi terhadap invasi bakteri. Human beta defensin-1 adalah peptida antimikroba dan pertahanan pertama terhadap infeksi.
Tujuan Penelitian: Membandingkan kadar ekspresi HBD-1 antara kelompok periodontitis kronis, periodontitis agresif dan normal
Bahan dan Metode: Kadar HBD-1 dari 94 sampel CKG subjek periodontitis kronis, periodontitis agresif dan normal diukur dengan ELISA
Hasil: Analisis Mann-Whitney menunjukkan perbedaan kadar HBD-1 antara periodontitis kronis dengan normal (p<0,05) dan tidak terdapat perbedaan signifikan (p>0,05) antara periodontitis agresif dengan normal, dan antara periodontitis kronis dengan periodontitis agresif.
Kesimpulan: Kadar HBD-1 pada CKG menurun pada kondisi periodontitis kronis dan periodontitis agresif.
Background: Periodontal disease is happened because inflammation reaction ro bacterial invasion. Human beta defensin-1 (HBD-1) is antimicroba peptide which regulate the first defense mechanism.Objectives: To compare level of HBD-1 between chronic periodontitis, aggressive periodontitis, and normal group.Material and Methods: Level of HBD-1 from GCF sample of chronic periodontitis, aggressive periodontitis, and normal group were assessed with ELISA.Results: Mann-Whitney analysis show different level of HBD-1 expression between chronic periodontitis and normal (p<0,05) and there was no significant difference (p>0,05) between aggressive periodontitis and normal, and between chronic periodontitis and aggressive periodontitis.Conclusion: Level of HBD-1 in GCF decreased in chronic periodontitis and aggressive periodontitis.
