Latar Belakang: Early childhood caries (ECC) merupakan penyakit kronik infeksius yang sering terjadi pada anak usia prasekolah, ditandai dengan adanya satu atau lebih gigi yang rusak atau hilang atau ditambal akibat karies. ECC disebabkan oleh mikroorganisme kariogenik seperti S. mutans serotype e dan Candida albicans. Faktor laju alir saliva pada dorsal lidah dapat memengaruhi perkembangan ECC. Tujuan: Menganalisis kuantitas antigen S. mutans serotype e dan antigen Candida albicans yang diisolasi dari dorsal lidah serta kaitannya dengan laju alir saliva anak ECC dan caries free. Metode: S. mutans serotype e dan Candida albicans dari dorsal lidah sampel ECC dan caries free diuji menggunakan indirect ELISA untuk memperoleh antigen dan dibaca dengan panjang gelombang 450 nm, kemudian nilai optical density kedua antigen tersebut dikorelasikan dengan laju alir saliva anak ECC dan caries free. Hasil: Tidak terdapat perbedaan (p>0,05) kuantitas antigen S. mutans serotype e dan Candida albicans pada anak ECC dan caries free. Terdapat kecenderungan hubungan positif antara kuantitas antigen S. mutans serotype e dan Candida albicans pada anak ECC dan caries free. Kuantitas antigen S. mutans serotype e dan Candida albicans paling tinggi ditemukan pada laju alir saliva normal anak ECC. Kesimpulan: Kuantitas antigen Streptococcus mutans serotype e lebih banyak ditemukan pada dorsal lidah anak ECC dibandingkan dengan antigen Candida albicans. Pada laju alir saliva normal anak ECC dan caries free terjadi peningkatan kuantitas antigen S. mutans serotype e dan Candida albicans.

Background: Early childhood caries (ECC) is a chronic infectious disease that often occurs in preschool children, characterized by the presence of one or more teeth that are damaged or missing or restored due to caries. ECC is caused by cariogenic microorganisms such as S. mutans serotype e and Candida albicans. Salivary flow rate in the dorsal tongue can influence the development of ECC. Objective: To analyze the quantities of S. mutans serotype e and Candida albicans antigens isolated from the dorsal tongue and their relation to the salivary flow rate in ECC and caries free children. Method: S. mutans serotype e and Candida albicans from the dorsal tongue of children with ECC and caries free children were tested using indirect ELISA to obtain the antigens and they were being read with wavelengths of 450 nm, then the optical density values of the two antigens were correlated with the salivary flow rate of ECC and caries free children. Result: There was no significance (p> 0.05) quantity of S. mutans serotype e and Candida albicans antigens in ECC and caries free. There is a tendency for a positive correlation between quantity of S. mutans serotype e and Candida albicans antigens in ECC and caries free children. The highest quantity of S. mutans serotype e and Candida albicans antigens was found in the normal salivary flow rate of ECC children. Conclusion: Quantity of Streptococcus mutans serotype e antigens were higher than Candida albicans in the dorsal tongue of ECC children. At the normal salivary flow rate of ECC and caries free children, there was an increase quantity of S. mutans serotype e and Candida albicans antigens.
