Latar Belakang: Celah bibir dan palatum merupakan kelainan kongenital yang paling sering terjadi pada regio orofasial. Pasien celah bibir dan palatum menunjukkan sejumlah permasalahan seperti defek tulang alveolar yang lebar, kehilangan gigi kongenital, supernumerary teeth, hipoplasia dan gigi impaks. Autologous alveolar bone grafting dianggap sebagai perawatan gold standard untuk rekonstruksi tulang alveolar dengan menggunakan tulang kanselus dari puncak ilium anterior. Namun, pengambilan tulang ilium bersifat invasif dan memiliki potensi terjadinya komplikasi. Mengingat hal tersebut, teknik rekayasa jaringan yang memanfaatkan scaffolds, faktor pertumbuhan, dan sel punca dipertimbangkan sebagai pilihan perawatan yang baru. Sel punca mesenkim bisa didapatkan dari jaringan pulpa, yang disebut dengan sel punca pulpa gigi sulung atau stem cells from exfoliated deciduous teeth (SHED) dan sel punca pulpa gigi permanen atau dental pulp stem cells (DPSC). Salah satu kriteria yang harus dimiliki sel punca mesenkim adalah mengekspresikan surface marker CD73, CD90, dan CD105. Pada pasien normal, penelitian yang membandingkan karakteristik antara SHED dan DPSC telah membuktikan bahwa keduanya merupakan sel punca mesenkim dengan mengekspresikan surface markersesuai dengan kriteria. Namun, pada pasien celah bibir dan palatum belum banyak diteliti. Tujuan: Menganalisis perbedaan persentase sel yang mengekspresikan surface marker (CD73, CD90, dan CD105) pada SHED dan DPSC pasien celah bibir dan palatum. Metode: Sel punca pulpa gigi sulung dan gigi permanen diisolasi dari jaringan pulpa pasien celah bibir dan palatum. Persentase sel yang mengekspresikan surface marker (CD73, CD90, dan CD105) dianalisis dengan uji flow cytometry. Hasil: Analisis flow cytometry menunjukkan bahwa baik SHED maupun DPSC mengekspresikan masing-masing surface marker dalam persentase yang tinggi (>90%). Setelah dilakukan uji Independent T-test untuk membandingkan ekspresi masing-masing surface markerpada kedua grup, didapatkan hasil >0,05. Kesimpulan: Tidak terdapat perbedaan bermakna antara ekspresi masing-masing surface marker pada SHED dan DPSC pasien celah bibir dan palatum.
Background: Cleft lip and palate is the most common congenital anomaly in the orofacial region. Cleft lip and palate patients present with a number of complaints such as wide alveolar bone defects, congenitally missing teeth, supernumerary teeth, hypoplastic dan impacted teeth. Autologous bone grafting is considered to be the gold standard for alveolar bone reconstruction using the cancellous bone harvested from the anterior iliac crest. However, the procedure is invasive and carries a risk of complications. Bearing all that in mind, tissue engineering that utilizes scaffolds, growth factors, and stem cells arises as a new therapeutic option. Mesenchymal stem cells can be obtained from dental pulp, which are called stem cells from exfoliated deciduous teeth (SHED) and dental pulp stem cells (DPSC). One of the criterias to define mesenchymal stem cells is the expression of surface markers CD73, CD90, and CD105. In normal patients, both SHED and DPSC have been known to express those surface markers. However, the expression of CD73, CD90, and CD105 in SHED and DPSC from cleft lip and palate patients has not been fully explored. Objective: To analyze the difference in the percentage of cells that express CD73, CD90, and CD105 in SHED and DPSC from cleft lip and palate patients. Methods: SHED and DPSC were isolated from dental pulp. The expression of surface markers were analyzed with flow cytometry. Results: Flow cytometry analysis showed that SHED and DPSC from cleft lip and palate patients highly express (>90%) surface markers that are associated with mesenchymal stem cells such as CD73, CD90, and CD105. The Independent T-Test was then performed to see a comparison between the expression of each surface marker in both groups and the value was >0.05. Conclusions: There is no significant difference between the percentage of cells that express each surface marker in SHED and DPSC from cleft lip and palate patients.
"Latar Belakang: Periodontitis disebabkan oleh infeksi mikroba sepertiStreptococcus sanguinisyang mengganggu respon imun dan integritas jaringan pendukung gigi.Ekstrak etanol kelopak bunga rosela (Hibiscus sabdariffa Linn.) memiliki kandungan antimikrobial terhadap bakteri Gram-positif seperti S. sanguinis. Untuk mengembangkan bentuk sediaan, dibuat gel ekstrak etanol kelopak bunga rosela.Tujuan: Mengetahui efektivitas antibakteri gel ekstrak etanol kelopak bunga rosela terhadap S. sanguinis. Metode: Studi in vitro metode difusi agar yang mengukur zona hambat (mm) gel rosela 10%, 15%, dan 25% yang dipaparkan pada agar Mueller Hinton terinokulasi bakteri S. sanguinis, diinkubasi 6 jam, serta metode total plate count (CFU/mL) untuk menghitung jumlah koloni hidup bakteri S. sanguinis setelah terpapar gel rosela 10%, 15%, dan 25%. Kontrol positif yaitu gel klorheksidin 0,2% dan kontrol negatif yaitu gel basis tanpa zat aktif. Hasil: Zona hambat gel ekstrak etanol kelopak bunga rosela konsentrasi 15% dan 25% berbeda bermakna dibandingkan kontrol (p<0,05), gel konsentrasi 10% tidak menghasilkan zona hambat. Ketiga konsentrasi gel secara signifikanmenurunkan jumlah koloni bakteri dibandingkan kontrol (p<0,05). Efek penghambatan terbesar terdapat pada gel konsentrasi 25%. Kesimpulan: Gel ekstrak etanol kelopak bunga rosela memiliki efek hambat terhadap bakteri S. sanguinis.
Background: Periodontitis is caused by microbial infection, such as Streptococcus sanguinisthat disturbs immune response and the integrity of tooth-supporting tissue. Roselle (Hibiscus sabdariffa Linn.) calyx ethanol extract has antibacterial properties against Gram-positive bacteria, including S. sanguinis. In order to develop the dosage form, roselle calyx ethanol extract gel was made. Objective:To observe the antibacterial effectiveness of roselle calyx ethanol extract gel against S. sanguinis. Method: in vitrostudy using disk diffusion method which measures clear zone of inhibition (mm)of 10%, 15%, and 25% roselle gel applied on Mueller Hinton agar inoculated with S. sanguinis, incubated for 6 hours, and total plate count method which counts the number of living S. sanguiniscolonies (CFU/mL)after being exposed to 10%, 15%, and 25% roselle gel. Positive control is 0.2% chlorhexidine gel and negative control is gel without active substances.Result: Inhibitory zones of 15% and 25% roselle gel have significant differences compared controls (p<0.05), 10% roselle gel did not show inhibitory zones.All three concentrations of gel significantly reduced the number of colonies compared to controls (p<0.05). Highest inhibitory effect was observed in 25% roselle gel.Conclusion: roselle calyx ethanol extract gel showed inhibitory effect against S. sanguinis.
