Karies gigi pada anak usia dini merupakan masalah kesehatan yang sangat serius karena merupakan penyakit infeksi kronis yang menular. Dalam beberapa tahun terakhir pandangan tentang neutrofil telah berubah secara dramatis. Neutrofil tidak hanya berperan sebagai pembunuh mikroba melalui proses fagositosis, pelepasan reactive oxigen species (ROS) dan peptida antimikrobialnya tetapi neutrofil turut mengatur aktifasi respon imun. Interleukin-8 (IL-8) berfungsi sebagai aktivator kuat dan kemoatraktan neutrofil oleh karena itu IL-8 merupakan mediator kunci dalam migrasi neutrofil ke lokasi peradangan dan infeksi. Untuk menganalisis hubungan dari jumlah S. mutans dan ekspresi IL-8 neutrofil saliva pada anak usia dini bebas karies dan severe early childhood caries (S-ECC). Perlakuan dilakukan pada dua kelompok yaitu isolasi dan menghitung jumlah S. mutans pada sampel saliva dan sampel hasil kumur dengan NaCl 1,5% yang diisolasi neutrofilnya kemudian dianalisis ekspresi IL-8 menggunakan flow cytometry dari 20 anak bebas karies dan 20 anak severe early childhood caries. Hasil nilai rata-rata diketahui bahwa jumlah S. mutans anak usia dini bebas karies lebih rendah (513.500,00±185.565,28 CFU/ml) dibandingkan dengan S-ECC (977.000,00±222.500,15 CFU/ml), sedangkan ekspresi IL-8 neutrofil saliva anak usia dini bebas karies lebih tinggi (3,31±0,50) dibandingkan dengan S-ECC (2,95+0,56). Penurunan ekspresi IL-8 neutrofil saliva kemungkinan sebagai penyebab meningkatnya jumlah S. mutans pada S-ECC.Correlation of Streptococcus mutans (S. mutans) Level and Interleukin 8 (IL-8) Expressions of Salivary Neutrophils in Severe Early Childhood Caries. Early childhood caries is a very serious health problem because it is a chronic infectious disease that is contagious. Dental caries begins after the primary teeth grow and develop on the tooth surface very quickly and progressively. In recent years the views of neutrophils have changed dramatically. Neutrophils not only act as a microbe killer through phagocytosis, the release of reactive oxigen species (ROS) and its antimicrobial peptide, but neutrophil activation also helps regulate the immune response. To analyze the relationship between the amount S. mutans and IL-8 expression of salivary neutrophils in severe early Childhood caries. Two groups, namely Isolation of S. mutans were performed on saliva samples taken from 20 caries-free and 20 severe early childhood caries and samples Nacl 1,5% mouthwash results of 20 caries-free and 20 severe early childhood caries salivary neutrophils that were analysis of IL-8 expression by flow cytometry. Based on the average value, it is known that S. mutans level in early Childhood caries-free is lower (513.500,00 +185.565,28 CFU/ml) in comparison to the severe early Childhood caries (977.000,00 +222.500,15 CFU/ml), but the expression of IL-8 neutrophil salivary neutrophils in early Childhood caries-free is higher (3,31+0,50) in comparison to the severe early Childhood caries (2,95+0,56). The increased S. mutans level is probably caused by the decrease in the expression of IL-8 salivary neutrophils in severe early childhood caries.

Abstract Objectives To analyze CD35/CD89 expression ratio on the surface of neutrophils as an early detection marker for S-ECC. Materials and Methods Saliva was collected from 4- to 6-year-old kindergarten students. Salivary neutrophils were obtained by instructing the subjects to rinse their mouth with 1 mL of sterile 1.5% NaCl for 30 seconds before expectorating it into a sterile glass. The expression of CFSE+CD35+ and CFSE+CD89+was measured and analyzed using flow cytometry. Results The expression of CFSE+CD89+ in the caries-free group (2.46 ± 0.39) was significantly lower than that in the S-ECC group (3.41 ± 1.11), with a p-value of 0.0001, while the expression of CFSE+CD35+ in the caries-free group was (2.35 ± 0.56) compared with (1.54 ± 0.35) (p = 0.0001) in the S-ECC group. Conclusions The expression ratio of CFSE+CD89+ and CFSE+CD35+constitutes a marker for S-ECC.

Abstract Background Streptococcus mutans (S. mutans) is one of the main cariogenic bacteria for caries. It was found that the clinical strains of S. mutans isolated from caries active population have stronger cariogenic ability than the isolates from caries-free (CF) people. Previous studies have found that curcumin can inhibit biofilm formation of S. mutans UA159. The objective of this study is to explore the antibiofilm effect of curcumin on the clinical isolates of S. mutans from severe early childhood caries(SECC). Results The isolates from SECC group had more biomass than CF group (t = 4.296, P < 0.001). The acidogenicity and aciduricity of the strains from two groups showed no significant difference. After treatment with curcumin, the viability of biofilm was reduced to 61.865% ± 7.108% in SECC and to 84.059% ± 10.227% in CF group at 24 h (P < 0.05). The net reduction of live bacteria and total bacteria in the SECC group was significantly higher than that of the CF group (live bacteria t = 3.305, P = 0.016; total bacteria t = 2.378, P = 0.045) at 5 min. For 24 h, the net reduction of live bacteria and total bacteria in the SECC group was significantly higher than that of the CF group (live bacteria t = 3.305, P = 0.016; total bacteria t = 2.378, P = 0.045). The reduction of biofilm thickness reduced significantly in 5 min (t = 4.110, P = 0.015) and in 24 h (t = 3.453, P = 0.014). Long-term (24 h) curcumin treatment inhibited the amount of EPS in SECC group from (25.980 ± 1.156) μm3/μm2 to (20.136 ± 1.042) μm3/μm2, the difference was statistically significant (t = 7.510, P < 0.001). The gene of gtfC, gtfD, ftf, gbpB, fruA and srtA in the CF group and the gtfB, gtfC, gtfD, ftf, gbpB, srtA in SECC group were respectively reduced after 5 min curcumin treatment. After 24 h treatment, the gtfB, gtfC, gtfD, ftf, gbpB, fruA and srtA in both two groups were downregulation, all the differences were statistically significant. Conclusions Curcumin has antibiofilm activity on clinical strains of S. mutans, especially for those isolated from SECC.
