In such conditions, a combination of dentin and a polymer like chitosan or poly (lactic co-glycolic) acid (PLGA) can be preferably used.…”

Objective: Dentin has become an interesting potential biomaterial for tissue engineering of oral hard tissues. It can be used as a scaffold or as a source of growth factors in bone tissue engineering. Different forms of dentin have been studied for their potential use as bone substitutes. Here we systematically review different methods of dentin preparation and the efficacy of processed dentin in bone tissue engineering.Methods: An electronic search was carried out in PubMed and Scopus databases for articles published from 2000 to 2016. Studies on dentin preparation for application in bone tissue engineering were selected. Results:The initial search yielded a total of 1045 articles, of which 37 were finally selected.Review of studies showed that demineralization was the most commonly used dentin preparation process for use in tissue engineering. Dentin extract, dentin particles (tooth ash), freeze-dried dentin, and denatured dentin are others method of dentin preparation. Conclusion:Based on our literature review, we can conclude that preparation procedure and the size and shape of dentin particles play an important role in its osteoinductive and osteoconductive properties. Standardization of these methods is important to draw a conclusion in this regard.

“…Sumber hidroksiapatit telah digunakan dengan berbagai sumber yang mengandung kalsium seperti: sisik ikan [6], batu kapur [7][8], membran cangkang telur [9], gigi sapi [10], tulang sapi [11], dan tulang ikan [12]. Ketersediaan hidroksiapatit menjadi masalah utama bagi dokter gigi sebagai pengguna utama biomaterial ini.…”

Tulang ikan patin telah berhasil disintesis menjadi hidroksiapatit melalui metode presipitasi. Tulang ikan Patin digunakan karena akan menghasilkan hidroksiapatit yang lebih biokompatibel dengan tulang. Model yang digunakan adalah percobaan laboratorium melalui metode presipitasi yang mensintesis tulang ikan patin yang telah dikalsinasi dengan asam nitrat, aquades, ammonium hidroksida dan diammonium hidrogen fosfat sehingga menghasilkan produk hidroksiapatit. Hasil FTIR menunjukkan bahwa terdapat gugus-gugus penyusun hidroksiapatit pada puncak puncaknya. XRD menunjukkan bahwa porduk yang dihasilkan memang benar hidroksiapatit karena sesuai dengan standar dari ICCS. Hasil dari SEM menunjukkan terdapat aglomerasi dari produk yang dihasilkan dikarenakan metode presipitasi itu sendiri.

“…Komposisi kimia tulang yang telah kering terdiri dari bahan organik dan anorganik dengan rasio 1:2. Bahan anorganik pada tulang sapi mengandung kalsium (32,6%), fosfor (15,2%), dan sisanya terdiri dari natrium, kalium, magnesium, tembaga, kobal, seng, mangan, dan sulfur [7]. Penyusun tulang sapi sebagian besar adalah bio-anorganik hidroksiapatit [Ca 10 (PO 4 ) 6 (OH) 2 ].…”

ABSTRAK: Tujuan penelitian ini adalah mempelajari kemampuan adsorpsi arang tulang sapi teraktivasi NaOH 0,4 M untuk menurunkan (reduksi) karakteristik tingkat kekeruhan, COD (chemical oxygen demand), kandungan Cr dan Pb dari limbah garmen yang dibandingkan dengan tanpa aktivasi. Kemampuan adsorpsi arang tulang tanpa dan teraktivasi (bio-anorganik-sorben) terhadap karakteristik limbah tersebut dikaitkan dengan karakterisasi (keasaman permukaan, jumlah situs aktif, gugus fungsi dan luas permukaan spesifik) serta waktu dan volume interaksi optimum. Hasil yang diperoleh bahwa aktivasi arang tulang dengan larutan NaOH 0,4 M dapat meningkatkan karakteristiknya (keasaman permukaan, jumlah situs aktif, intensitas gugus fungsi O-H dan luas permukaan spesifik) dibandingkan dengan yang tanpa aktivasi. Aktivasi NaOH pada arang tulang dapat meningkatkan kemampuan adsorpsi dalam menurunkan tingkat kekeruhan, COD, dan kandungan Cr dan Pb dari sampel limbah cair garmen dibandingkan dengan kemampuan arang tanpa aktivasi. Waktu interaksi optimum yang diperlukan dalam menurunkan karakteristik tingkat kekeruhan dan COD adalah 90 menit, dengan volume interaksi optimum 20 mL. ABSTRACT: The aim of this reseach was to study the adsorption ability of cow bone charcoal activated with 0.4 M NaOH to reduce the turbidity level, the chemical oxygen demand (COD), the Pb and Cr content of garment waste water and to compare with the non-activated ones. The adsorption ability of both activated and non-activated bone charcoal (bio-inorganic-sorbent) was related to their characteristics which are the surface acidity, the active sites, the fuction groups, the specific surface area, the volume and time optimum interaction as well. The result showed that activation can increase the surface acidity, the active sites, the O-H fuction groups intensity and the specific surface area compared with non-activated ones. The activated charcoal significantly reduced the COD and the turbidity level, the Pb and Cr content of garment waste water comparing with the non-activated ones. Time contact optimum to reduce its characteristics is 90 minutes and volume interaction optimum is 20 mL.
