"Latar belakang: Trietylene glycol dimethacrylate (TEGDMA) merupakan salah satu monomer yang terkandung dalam bahan tambal resin komposit. Jika polimerisasi tidak sempurna, TEGDMA dapat dengan mudah terlepas ke dalam rongga mulut beberapa menit hingga jam setelah penambalan, dan dapat berpenetrasi ke dalam pulpa. TEGDMA yang terlepas dilaporkan bersifat toksik terhadap jaringan dan sel tubuh.
Tujuan: menentukan efek TEGDMA terhadap protein total dan profil protein sel-sel pulpa gigi.
Metode: sel-sel pulpa didapat dari jaringan pulpa gigi sehat yang baru diekstraksi, kemudian dikultur pada medium kultur DMEM. Setelah sel kultur tampak confluent (±2 malam), dilakukan subkultur dari kultur primer tersebut, yang kemudian diinkubasi kembali pada suhu 37° C dan 5% CO2 selama 1 malam pada 24- well plate. Kemudian dilakukan pemaparan TEGDMA dengan konsentrasi 4mM, 8mM dan 12mM, selama 24 jam, sedangkan pada kelompok kontrol tidak dilakukan pemaparan TEGDMA. Penentuan konsentrasi protein total sel pulpa dilakukan dengan menggunakan Bradford protein assay. Profil protein sel pulpa diidentifikasi dengan teknik SDS-PAGE. Analisa berat molekul protein sampel dilakukan dengan menggunakan Gel Doc (Band Analysis Quick Guide).
Hasil: Rerata konsentrasi protein total sel (µg/ml ± SD) pada kelompok perlakuan dengan TEGDMA 4mM (22762,27±3385,87) dan 8mM (20268,44±1701,14) memiliki nilai dibawah kelompok kontrol (24253,77±3072,88). Sedangkan kelompok perlakuan dengan TEGDMA 12mM (23706,51±3214,52) memiliki nilai konsentrasi protein total sel di atas kelompok 4mM dan 8mM, namun masih tetap di bawah kelompok kontrol. Berdasarkan uji statistik dengan one way ANOVA, hanya kelompok TEGDMA 8mM yang memiliki perbedaan rerata konsentrasi protein total sel yang bermakna (p=0.037) terhadap kelompok kontrol. Selanjutnya dari gambaran profil protein yang terbentuk pada gel elektroforesis, tampak perubahan profil protein sel pada setiap kelompok setelah paparan TEGDMA.
Kesimpulan: Pada penelitian ini terjadi penurunan konsentrasi protein total sel dan perubahan profil protein sel pulpa gigi setelah pemaparan TEGDMA dengan konsentrasi 4mM, 8mM, dan 12mM.

Konsentrasi protein dan polipeptida yang ada dalam saliva penting dalam pemeliharaan kesehatan mulut dan homeostasis dengan perubahan kualitatif dan kuantitatif dari proteome saliva. Tujuan: Penelitian ini bertujuan untuk menganalisis hubungan total konsentrasi protein dan profil protein saliva dengan status kebersihan rongga mulut (OHI-S) dan status karies dental (DMF-T dan def-t) pada subjek kelompok usia dewasa muda dan anak-anak. Metode: Penelitian ini bersifat deskriptif laboratorik dengan menggunakan Uji Bradford untuk menetapkan total konsentrasi protein dan Uji SDS-PAGE untuk menetapkan profil protein saliva. Sampel uji berupa sampel saliva berjumlah 18 sampel masing-masing kelompok usia (total 36 sampel), dengan diketahui status kebersihan rongga mulut (OHI-S) dan status karies dental (DMF-T dan def-t). Analisis statistik dijalankan dengan menggunakan uji normalitas, kemudian Uji T test-independent. Untuk menganalisis hubungan dilakukan uji korelasi spearman. Analisis data menggunakan SPSS iOS versi 22.0. Hasil: Terdapat perbedaan signifikan antara total konsentrasi protein saliva kelompok usia dewas muda dan anak-anak (p = 0.001 (p<0.05)), namun tidak terdapat korelasi signifikan antara total konsentrasi protein saliva kelompok usia terhadap OHI-S dan DMF-T atau def-t, serta terdapat perbedaan profil protein saliva berupa perbedaan frekuensi protein bands yang muncul pada masing-masing profil protein.  Kesimpulan: Total konsentrasi protein dan profil protein saliva tidak berhubungan dengan OHI-S dan DMF-T atau def-t pada kelompok usia dewasa muda dan anak-anak, namun tetap memiliki tendensi korelasi.

Human oral health contains various microorganisms that can form a community that affects oral health. According to Riskesdas 2018, the prevalence of caries in Indonesia ranges from 60-80%. The concentration of proteins and polypeptides in saliva is important in maintaining oral health and homeostasis through qualitative and quantitative changes in the salivary proteome.  Objective: This study aims to analyze the relationship between total protein concentration and saliva protein profile with oral hygiene status (OHI-S) and dental caries status (DMF-T and def-t) in adult and child age groups. Methode: This study is a deskriptive laboratory analysis using Bradford tests to determine total protein concentration and SDS-PAGE tests to determine saliva protein profiles. The sample consisted of 18 saliva samples from each age group (total 36 samples), with OHI-S and dental caries status (DMF-T and def-t) determined. Statistical analysis was performed using normality tests, followed by independent sample t-tests. To analyze the relationship, Spearman's correlation test was conducted. Data analysis used SPSS iOS version 22.0. Result: A significant difference was found in the total saliva protein concentration between the young adult and child groups (p = 0.001, p < 0.05), but no significant correlation was found between total saliva protein concentration and OHI-S and DMF-T or def-t status. There was a difference in saliva protein profiles, manifested as differences in the frequency of protein bands in each protein profile.  Conclusion: The total protein concentration and saliva protein profiles do not have a significant relationship with OHI-S and DMF-T or def-t status in young adult and child age groups, but they still show a tendency to correlate."

"Triethylene glycol dimethacrylate (TEGDMA) is a common component of the bonding agents and resin composites used in dentistry for restorative dentistry. However, TEGDMA could be released from composite resins following incomplete polymerization and degradation processes by salivary enzymes in the mouth. Subsequently, TEGDMA is available in saliva and diffuses toward and affects the dental pulp which contains various cells, and thus may cause severe cytotoxic effects.
Objectives: To determine the total protein concentration of human dental pulp cells following exposure to TEGDMA.
Materials & methods: Dental pulp cells were isolated from the pulp of the freshly extracted teeth and cultured in DMEM for 48 h (37°C, 5% CO2). Then, 2 mM, 4mM and 8 mM TEGDMA were added to these cells and incubated for 24 h. The total protein was measured by Bradford Protein Assay.
Results: The total protein concentration of dental pulp cell after expsured to 4 mM, 8mM, and 12 mM TEGDMA were statistically lower (22762.27 ug/ml ± 3385.87; 20268.44 ug/ml ± 1701.14; 23706.51 ug/ml ± 3214.52; respectively) than the control group (24253.77 ug/ml ± 3072.88). Furthermore, the total protein concentration of culture medium after exposured to 4 mM, 8mM, and 2 mM TEGDMA, were statustically higher (28635 ug/ml ± 2373.4; 35288.41 ug.ml ± 3469.48; 38199.79 ug/ml ± 2752.47; respectively) when compared with the controls (27073.85 ug/ml ± 2772.47).
Conclusion: 2 mM, 4 mM, and 8 mM TEGDMA caused cytotoxicity to human dental pulp cells showed by decreasing the total protein of cells and increasing total protein of the culture medium."

"Demam dengue (DD) merupakan penyakit infeksi virus dengue (DENV) dengan vektor Aedes aegypti dan Aedes albopictus. Secara global, terjadi peningkatan kasus DD sebanyak enam kali lipat dari tahun 2010 hingga 2016 namun sampai saat ini regimen terapi DD adalah terapi suportif yaitu terapi cairan dan simptomatik. Ekstrak Curcuma longa telah diteliti memiliki potensi sebagai antiviral untuk DENV. Namun, mekanisme penghambatannya masih belum diketahui sehingga penelitian ini dilakukan untuk mengetahui efek ekstrak Curcuma longa terhadap penghambatan reseptor dan penempelan virus dengue serotipe 2 (DENV-2) secara in vitro dan ikatan curcumin dengan protein E secara in silico.
Penelitian ini merupakan studi eksperimental untuk menganalisa mekanisme kerja dari ekstrak Curcuma longa sebagai antivirus terhadap DENV-2 menggunakan sel Vero sebagai sel uji dan in silico untuk mengetahui ikatan energi curcumin dengan protein E DENV. Focus assay dan MTT Assay digunakan untuk menilai penghambatan reseptor dan protein virus, serta viabilitas sel secara berturut-turut. Konsentrasi ekstrak Curcuma longa yang digunakan yaitu dua kali IC50 (17,91 μg/mL). DMSO digunakan sebagai kontrol.
Persentase hambat pada reseptor sel dan protein virus masing-masing adalah 98,67 ± 1,33% dan 2,29 ± 1,19%. Persentase viabilitas sel pasca pemberian ekstrak Curcuma longa adalah 97,07 ± 0,50%. Energi ikatan pada konformasi terbaik curcumin dengan protein E bernilai -2,71 kkal/mol dengan konstanta inhibisi 10,34 mM. Ekstrak Curcuma longa memiliki efek penghambatan reseptor sel lebih baik daripada protein E virus serta memiliki ikatan yang relatif baik dengan protein E.

Dengue fever (DF) is an disease caused by dengue virus infection (DENV). From 2010 to 2016, there has been a sixfold increase of DF cases globally. However, therapy for DF currently only consist of supportive treatments. Curcuma longa (turmeric) extract has been studied and its potential antiviral activity against dengue serotype 2 virus was found but inhibitory mechanism is still unknown. This research aims to find the inhibitory effect of turmeric extract against cell receptor and attachment protein of DENV-2 in vitro and binding energy between curcumin and dengue protein E in silico.
Experimental, in vitro study was done to analyze inhibitory mechanism of turmeric extract as antivirus to DENV-2 using Vero cell as test cell. In silico calculation of binding energy between curcumin and DENV protein E was also done using a docking software. Focus assay and MTT assay were used to evaluate receptor and viral attachment protein inhibition as well as cell viability, respectively. Turmeric extract concentration used was twice of IC50 (17,91 μg/mL) . DMSO was used as control.
Inhibition percentage on cell receptor and viral attachment protein yielded 98,67±1,33% and 2,29±1,19% respectively. Viability percentage of the cells after treatment with turmeric extract is 97,07 ± 0,50%. Binding energy at the best conformation between curcumin and viral protein E is -2.71 kcal/mol with inhibition constant of 10,34 mM. Turmeric extract has a higher inhibition effect against cell receptor compared to viral attachment protein and has a relatively strong bond with protein E.
