"In cases of advanced alveolar bone loss frequently associated with periodontal pockets that may not be accessible by conservative therapy, corrective surgery is often indicated as osseous resective and complete debridement therapy. Transplantation of osseous fill material is often necessary, as a surgical intervention may create an alveolar bone defect. In this reported case of surgery, a cortico-cancellous bone graft taken from the mandibular symphysis was transplanted in a mixture with human mineralized bone from the Dr. Soetomo Hospital Surabaya Bone Bank, expecting for osseous regeneration to reduce the bony defect. Six months after surgery the morphology of the reconstructed alveolar process was satisfactory and showing new growth of bone"

"Latar Belakang: Trauma dentoalveolar merupakan trauma umum terjadi di seluruh dunia yang melibatkan area gigi, tulang alveolar dan jaringan pendukung gigi. Tatalaksana alternatif untuk meregenerasi tulang secara cepat dan aman sehingga dapat berintegrasi baik dengan tubuh adalah dengan prosedur bone grafting. Beberapa jenis bone graft yang tersedia adalah Bio-Oss® dan prototipe karbonat hidroksiapatit. Kedua jenis bone graft memiliki perbedaan pada sumber material. Tujuan: Mengevaluasi perbandingan sitotoksisitas dan mineralisasi sel MC3T3-E1 pada bone graft prototipe karbonat hidroksiapatit dan Bio-Oss®. Metode: Jumlah spesimen yang digunakan dalam penelitian sebanyak 21 spesimen yang terdiri dari uji sitotoksisitas dengan MTT Assay sebanyak 12 spesimen pada 96 well-plate dan uji mineralisasi dengan pewarnaan Alizarin Red sebanyak 9 spesimen pada 24 well-plate. Uji sitotoksisitas dimulai dengan sel MC3T3-E1 dalam medium ekstrak bone graft selama 24 jam. Kemudian, dilanjutkan dengan inkubasi sel dengan larutan MTT selama 2 jam. Uji mineralisasi dilakukan dengan inkubasi sel MC3T3-E1 dalam medium diferensiasi bone graft selama 21 hari. Uji pewarnaan Alizarin Red dilakukan selama 20 menit. Hasil: Berdasarkan uji MTT assay, nilai viabilitas sel pada kedua bone graft yang diuji berada di atas 70% yang dikategorikan tidak sitotoksik berdasarkan acuan SNI ISO 10993-5:2015. Kedua bone bone graft tersebut memiliki perbedaan viabilitas sel secara signifikan (p<0,05). Bone graft prototipe karbonat hidroksiapatit memiliki persentase viabilitas sel lebih tinggi dibandingkan dengan Bio-Oss®. Berdasarkan uji pewarnaan Alizarin Red, bercak kecoklatan yang diperoleh pada spesimen yang tidak terkontaminasi dapat diduga bukan hasil mineralisasi tulang. Kesimpulan: Berdasarkan uji MTT assay, Bone graft prototipe karbonat hidroksiapatit dan Bio-Oss® bersifat tidak sitotoksik. Viabilitas sel pada bone graft prototipe karbonat hidroksiapatit lebih tinggi dari Bio-Oss®. Berdasarkan uji pewarnaan Alizarin Red, nodul mineralisasi tulang melalui pewarnaan Alizarin Red belum berhasil dilakukan sempurna karena adanya kontaminasi. Berdasarkan data spesimen yang tidak terkontaminasi, diperoleh bahwa prototipe karbonat hidroksiapatit dan Bio-Oss® tidak menghasilkan bercak nodul mineralisasi.

Background: Dentoalveolar trauma is a common global trauma involving the teeth, alveolar bone and supporting tissues of the teeth. An alternative treatment to regenerate bone quickly and safely so that it can integrate well with the body is the bone grafting procedure. Some types of bone graft available are Bio-Oss® and the carbonate hydroxyapatite prototype. The two types of bone graft have differences in material sources. Objective: To evaluate the comparison of cytotoxicity and mineralization of MC3T3-E1 pre-osteoblast cells in carbonate hydroxyapatite prototype and Bio-Oss®. Methods: The number of specimens used in the research was 21 specimens, consisting of 12 specimens cytotoxicity tests with MTT Assay on 96-well plates and 9 specimens mineralization tests with Alizarin Red staining on 24-well plates. The cytotoxicity test was initiated with MC3T3-E1 cells in bone graft extract medium for 24 hours. The cells were then incubated with MTT solution for 2 hours. The mineralization test was carried out by incubating MC3T3-E1 cells in bone graft diferentiation medium for 21 days. The Alizarin Red staining test was performed for 20 minutes. Results: Based on the MTT assay test, the cell viability value in the two bone grafts tested was above 70% which was categorized as non-cytotoxic based on the SNI ISO 10993-5:2015. The two bone grafts showed significant differences in cell viability (p<0.05). The carbonate hydroxyapatite prototype bone graft has a higher percentage of cell viability compared to Bio-Oss®. Based on the Alizarin Red staining test, the brownish spots obtained in the uncontaminated specimens are not considered to be the result of bone mineralization. Conclusion: Based on the MTT assay test, carbonate hydroxyapatite prototype and Bio-Oss® bone grafts are not cytotoxic. Cell viability in the hydroxyapatite carbonate prototype bone graft was higher than Bio-Oss®. Based on the Alizarin Red staining test, bone mineralization nodules using Alizarin Red staining have not been completely successful due to contamination. Based on uncontaminated specimen data, it was found that the hydroxyapatite carbonate prototype and Bio-Oss® did not produce mineralized nodules."

"Defek tulang merupakan kondisi yang sering dijumpai di daerah mulut dan maksilofasial. Rekonstruksi perlu dilakukan untuk mengatasi hal ini. Rekonstruksi dapat dilakukan dengan menggunakan material tandur tulang sintetik, salah satunya adalah biomaterial komposit hidroksiapatit-kitosan. Suatu biomaterial yang bertindak sebagai bahan tandur tulang harus memiliki kemampuan bioaktivitas, yang dinilai secara in vitro dari kemampuannya membentuk lapisan bone-like apatite pada permukaannya setelah diberikan perlakuan dalam cairan yang analog plasma tubuh. Pada uji in vitro dalam simulated body fluid selama 2, 4, 6 dan 8 hari nampak terbentuk lapisan bone-like apatite pada permukaan yang dikonfirmasi dengan pemeriksaan SEM dan XRD.

Bone defect in oral and maxillofacial region is common occurred. Reconstruction, regardless the etiology is required. Bone graft materials as reconstruction material can be made synthetically, one of them is hydroxyapatite-chitosan composite. This biomaterial needs bioactive ability to act as bone graft. Bioactive ability can be examined by the formation of bone-like apatite on the composite surface after incubating in human plasma analogue solution. In this study, the hydroxyapatite-chitosan granules show bone-like apatite formation on the surface after incubation in simulated body fluid which then confirmed using SEM and XRD analysis for 2, 4, 6 and 8 days."

"Latar Belakang : Teknik bone engineering dalam rekonstruksi mandibula banyak dilakukan di bidang bedah mulut guna keberhasilan proses rehabilitasi. Penambahan dua hal yang memungkinkan untuk membantu proses penyembuhan adalah dengan bone graft dan penambahan growth factors seperti Platelet Rich Plasma (PRP). Penggunaan bone graft pada defek tulang yang besar dapat membantu penyembuhan luka. Autogenous bone graft merupakan jenis graft yang paling sering digunakan, dikarenakan sifatnya yang osteogenik, osteoconductive dan osteoinductive. Vascularized bone graft merupakan terapi pilihan pada defek mandibula dengan panjang lebih dari 6 cm. Namun non vascularized bone graft juga menjadi pilihan karena memiliki beberapa keuntungan seperti kontur yang lebih baik, memiliki volume tulang yang cukup untuk keperluan estetik atau insersi implan. Serta merupakan terapi pilihan pada defek tulang kurang dari 6 cm. Tetapi resiko resorpsi pada non vascularized bone graft lebih besar. Penambahan PRP yang mengandung banyak growth factor dapat membantu proses rehabilitasi penyembuhan jaringan tulang. Salah satunya TGF-β yang membantu peningkatan jumlah osteoblas untuk penyembuhan jaringan tulang. Pada penelitian ini penambahan PRP pada autogenous bone graft non vascularized diharapkan mampu membantu penyembuhan tulang, dengan melakukan pengamatan pada jumlah osteoblas. Tujuan : Mengevaluasi pengaruh penambahan platelet rich plasma pada penyembuhan tulang mandibula dengan autogenous bone graft dilihat dari jumlah osteoblas (studi pada Ovis Aries) Material dan Metode : Penelitian quasi eksperimental in vivo dengan membagi dua kelompok, kelompok dengan pemberian autogenous bone graft dan kelompok dengan pemberian autogenous bone graft dan penambahan PRP. Kemudian dilakukan evaluasi pengaruh pemberian platelet rich plasma pada penyembuhan tulang mandibula dengan autogenous bone graft dilihat dari jumlah osteoblas (studi pada Ovis Aries) Kesimpulan : Terdapat perbedaan bermakna antara jumlah osteoblas kelompok dengan pemberian autogenous bone graft dan kelompok dengan pemberian autogenous bone graft dan penambahan PR

Background: Bone engineering techniques in mandibular reconstruction are mostly performed in the field of oral surgery for the success of the rehabilitation process. Two additional things that make it possible to help the healing process are bone graft and the addition of growth factors such as Platelet rich plasma (PRP). The use of bone grafts in large bone defects can aid in wound healing. Autogenous bone graft is the type of graft that is most often used, because of its osteogenik, osteoconductive and osteoinductive properties. Vascularized bone graft is the treatment of choice in mandibular defects longer than 6 cm. However, non-vascularized bone graft is also an option because it has several advantages such as better contours, having sufficient bone volume for aesthetic purposes or implant insertion. And is the treatment of choice for bone defects less than 6 cm. But the risk of resorption in the non-vascularized bone graft is greater. The addition of PRP which contains a lot of growth factors can help the rehabilitation process of healing bone tissue. One of them is TGF-β which helps increase the number of osteoblass for healing bone tissue. In this study, the addition of PRP to non-vascularized autogenous bone graft is expected to be able to help bone healing, by observing the number of osteoblass. Objective: To evaluate the effect of platelet rich plasma administration on the healing of mandibular bone with autogenous bone graft based on the number of osteoblass (study on Ovis Aries). Material and Methods: This in vivo analytical experimental study was divided into two groups, a group with autogenous bone graft and a group with autogenous bone graft and the addition of PRP. Then an evaluation of the effect of platelet rich plasma on the healing of mandibular bone with autogenous bone graft was evaluated from the number of osteoblass (study in Ovis Aries). Conclusion: There is a significant difference between the number of osteoblass in the group with autogenous bone graft and the group with autogenous bone graft and the addition of PRP."

"ABSTRAKPendahuluan Penggunaan tandur tulang lokal saat ini masih menjadi pilihan utama dalam tatalaksana fusi posterolateral pada kasus spondilosis lumbal di negara berkembang. Rendahnya tingkat fusi yang dihasilkan oleh tindakan ini mendorong penggunaan alternatif material lain. Penambahan aspirat sumsum tulang pada tandur tulang lokal dapat menjadi pilihan yang efektif dalam tatalaksana fusi posterolateral pada pasien spondilosis lumbal, namun saat ini belum ada data mengenai luaran klinis dari tatalaksana jenis ini di Indonesia. Metode Penelitian ini merupakan metode Kohort Retrospektif pada 38 pasien dengan tatalaksana fusi posterolateral dengan menggunakan tandur tulang lokal yang terbagi atas 19 pasien kelompok dengan penambahan aspirat sumsum tulang dan 19 pasien kelompok tanpa penambahan aspirat sumsum tulang. Seluruh pasien mendapatkan tindakan operasi setelah tindakan konservatif gagal dalam mengatasi keluhan nyeri. Evaluasi klinis pada masing-masing kelompok menggunakan skor IDO dinilai sebelum operasi, bulan ke-3 dan ke-6 setelah operasi. Hasil Tiga orang Ahli Orthopaedi Divisi Tulang Belakang melakukan operasi fusi posterolateral dan stabilisasi posterior. Perbandingan skor IDO sebelum operasi di antara kedua kelompok tidak menunjukan perbedaan yang bermakna. Tidak terdapat perbedaan bermakna rerata skor IDO pada kedua kelompok hingga bulan ketiga. Namun, perbandingan skor IDO pre operasi dan 6 bulan paska operasi menunjukkan kelompok dengan penambahan aspirat sumsum tulang akan menghasilkan rerata skor IDO lebih baik. Kesimpulan Luaran klinis pasien spondilosis lumbal yang menjalani fusi posteralateral menggunakan tandur tulang lokal dengan penambahan aspirat sumsum tulang menunjukkan hasil yang baik. Penambahan aspirat sumsum tulang pada fusi posterolateral menggunakan tandur tulang lokal dapat dipertimbangkan sebagai alternatif bagi pasien spondilosis lumbal yang diindikasikan untuk tindakan operatif.

ABSTRACTIntroduction The use of local bone graft still a mainstay in posterolateral fusion surgery for lumbar spondylosis cases in developing countries. Low rates of fusion encourage the alternative use of other materials. The addition of bone marrow aspirates in the local bone graft may be an option in the treatment of posterolateral fusion in the lumbar spondylosis patients, however there is no data on the clinical outcomes of treatment of this procedure in indonesia. Methods A retrospective cohort study was conducted in 38 patients treated by posterolateral fusion using local autograft that were divided into 19 patients with addition of bone marrow aspirates and 19 patients without addition of bone marrow aspirates. All patients received surgery after conservative treatments failed to address the complaint of pain. Clinical evaluation in each group using ODI score assessed preoperatively, 3rd, and 6th month postoperatively. Results Three Orthopedic Spine Surgeon performed posterolateral fusion and posterior stabilization. Comparison of preoperative ODI score between the two groups showed no significant difference. There were no significant differences in ODI score mean in both groups in 3 months after surgery. However, the bone marrow aspirate group produced a better mean difference of ODI score after 6 months. Conclusions The clinical outcomes of lumbal spondylosis patients undergoing posteralateral fusion using local autograft with addition of bone marrow aspirate showed good results. The addition of bone marrow aspirates in posterolateral fusion using local bone graft can be considered as an alternative for lumbar spondylosis patients who are indicated for surgery. "

"Purpose of the study: This study is undertaken to investigate the prevalence of smoking among dental undergraduates students in the University of Malaya, and to study the effects of smoking on the interproximal bone heights. Materials and method: A smoking habits questionnaire was distributed to the 299 Dental Undergraduate students of Year 2 to Year 5. Students were divided into groups of smokers (history of smoking for at least 1 year), former smokers (history of smoking and stopped more than 1 year) and non smokers (no smoking history). Two bitewing radiographs (left and right) were taken from 14 smokers and 5 former smokers. In addition, 14 students were randomly picked as control group, and their previously taken bitewing radiographs were collected. Interproximal bone loss defined as the distance (mm) from CEJ to the alveolar crest (AC) was measured using caliper, magnifier and metal ruler. Results: The prevalence of smokers and former smokers among dental students was 5.57% and 1.99%, respectively. Mean ± SEM of the CEJ-AC distance for smokers and non smokers was 1.063 ± 0.066 mm and 0.849 ± 0.050 mm, respectively. The difference was statistically significant between the smokers and non smokers (p<0.05). Mean ± SEM of bone loss among the smoker was 0.204 ± 0.066 mm. There was no satistically significant difference between former smokers and non smokers (p>0.05). Premolar is the most affected tooth in smokers, with a mean ± SEM of the CEJ-AC distance of 1.350 ± 0.102 mm. Conclusions: Smoking prevalence among dental undergraduate students was very low. Smokers have more bone destruction than the non-smokers."

"Latar Belakang: Alveolar bone loss dapat terjadi karena ketidakseimbangan remodeling tulang. Selain kehilangan tinggi, tulang alveolar juga mengalami penurunan volume tulang trabekula. Sudah banyak studi yang menilai densitas tulang dengan status periodontal, namun masih sangat sedikit yang melakukannya pada subjek dengan metabolisme tulang yang sehat. Tujuan: Memperoleh hasil evaluasi densitas radiografik interproksimal individu laki-laki dan perempuan usia 25-40 tahun dengan kondisi kehilangan tinggi alveolar sampai dengan setengah akar. Metode: Studi cross-sectional dengan 160 sampel (80 tinggi alveolar normal dan 80 kehilangan tinggi alveolar) radiograf panoramik digital individu laki-laki dan perempuan usia 25-40 tahun dari data sekunder di RSKGM FKG UI. Evaluasi densitas radiografik menggunakan metode pixel intensity dari hasil pengukuran nilai rerata graylevel menggunakan aplikasi I-Dixel Morita di interproksimal alveolar regio premolar dua mandibula. Selanjutnya, evaluasi kesepakatan pengukuran intraobserver dan interobserver dilakukan dengan uji reliabilitas interclass correlation coefficient (ICC). Analisis deskriptif dan uji komparatif dilakukan antar kategori kondisi tinggi alveolar dan jenis kelamin. Hasil: Hasil analisis rerata densitas berdasarkan kondisi tinggi alveolar, didapati terdapat perbedaan bermakna secara statistik antara kondisi tinggi alveolar normal dan kehilangan tinggi alveolar. Evaluasi densitas interproksimal kondisi kehilangan tinggi alveolar lebih rendah (120.61 ± 1,92) dibandingkan kondisi tinggi alveolar normal (135.71 ± 1,57). Pada analisis rerata densitas antar jenis kelamin, terdapat perbedaan bermakna antar jenis kelamin dengan kondisi tinggi alveolar berbeda, tetapi antar jenis kelamin dengan kondisi tinggi alveolar yang sama tidak ditemukan perbedaan yang bermakna. Densitas interproksimal pada kondisi tinggi alveolar normal kelompok subjek perempuan (135,10 ± 1,90) memiliki rata-rata densitas lebih rendah dibandingkan kelompok subjek laki-laki (137,80 ± 2,41). Kesimpulan: Terdapat perbedaan bermakna densitas interproksimal alveolar antara kelompok kondisi tinggi alveolar normal dan kehilangan tinggi alveolar, serta tidak ditemukan perbedaan bermakna antar jenis kelamin pada kondisi tinggi alveolar yang sama.

Background: Alveolar bone loss occur because of the imbalance of bone remodeling process. In addition to decrease of alveolar height, it reduce trabecular volume as well. Several studies have already address the assessment of bone density with periodontal status, but there is little knowledge to assess it with healthy subjects. Objective: The aim of this study was to obtain results of interproximal radiographic density evaluation of male and female individuals aged 25-40 years old with the condition og losing alveolar height up to half of the root. Method: Cross-sectional study with 160 samples (80 normal alveolar height and 80 loss of alveolar height) digital panoramic of male and female individuals 25-40 years old using secondary data at RSKGM FKG UI. Evaluation of radiographic density used the pixel intensity method from the result of measuring mean graylevel value with I-Dixel Morita application in the alveolar interproximal region of the mandibular second premolar. Furthermore, the reliability evaluation of intraobserver and interobserver measurement was carried out by testing interclass correlation (ICC). Descriptive and comparative tests were permorfed between categories of alveolar height conditions and gender. Result: The analysis of average density between different alveolar height showed there was a statistically significant difference between normal alveolar height and decreased alveolar height. Evaluation of interproximal density in condition loss of alveolar height was lower (120,61 ± 1,92) than in condition normal alveolar height (135.71 ± 1,57). In average density between genders analysis showed statistically significant differences were found between genders with different alveolar height conditions, but there is no significant difference were found between gender with same alveolar height conditions. The interproximal density in normal alveolar height of the female subject group (135,10 ± 1,90) had an average density lower than the male subject group (137,80 ± 2,41). Conclusion: There was significant difference of interproximal density between normal alveolar height group and loss of alveolar height, and there was no significant difference between genders on same alveolat height condition"
