Plak gigi diawali oleh bakteri primer seperti Streptococcus sanguinis membentuk biofilm matang melalui koagregasi dengan bakteri kariogenik seperti Streptococcus mutans . Kontrol plak menggunakan obat kumur klorheksidin 0,2% dapat menimbulkan efek samping. Keanekaragaman hayati di Indonesia berpotensi sebagai alternatif kontrol plak berbahan herbal, seperti ekstrak daun kersen ( Muntingia calabura ). Tujuan: Mengetahui aktivitas antibakteri ekstrak daun kersen ( Muntingia calabura ) dalam menghambat pertumbuhan bakteri Streptococcus sanguinis . Metode: Penelitian laboratoris in vitro dengan post-test only control group design . Besar sampel sebanyak 28 sampel, terdiri dari K+ (klorheksidin glukonat 0,2%), K- (akuades), serta kelompok perlakuan yaitu ekstrak daun kersen ( Muntingia calabura ) P1 (6,25%), P2 (12,5%), P3 (25%), P4 (50%), dan P5 (100%). Uji daya hambat dengan metode dilusi agar berdasarkan pengamatan visual tumbuh atau tidak tumbuh bakteri Streptococcus sanguinis . Data dianalisis menggunakan uji Cramer's V dan Fisher’s Exact. Hasil: Ekstrak daun kersen ( Muntingia calabura ) P3 (25%), P4 (50%), dan P5 (100%) tidak menunjukkan pertumbuhan bakteri serupa dengan hasil K+ dan berbeda signifikan dengan K-, dengan nilai KHM pada konsentrasi 25%. Kesimpulan: Terdapat efektivitas antibakteri ekstrak daun kersen ( Muntingia calabura ) terhadap pertumbuhan Streptococcus sanguinis pada konsentrasi 25%. }, issn = {3090-7411}, pages = {15--24} doi = {10.14710/actodont.29568}, url = {https://ejournal2.undip.ac.id/index.php/actodont/article/view/29568} }
