Latar belakang : Rekonstruksi defek jaringan tulang merupakan tantangan utama yang dihadapi ahli bedah mulut dan maksilofasial. Elemen dasar yang dibutuhkan dalam suatu rekayasa jaringan adalah sel, scaffold matriks serta molekul stimulan growth factors . Bagaimana sifat mekanik dari scaffold kitosan/hidroksiapatit/kolagen produksi BATAN, Jakarta, belum pernah diteliti. Tujuan : Menganalisa sifat mekanik scaffold kitosan/hidroksiapatit/kolagen produksi BATAN, Jakarta, sebelum dan setelah direndam dalam simulated body fluid selama 8 hari. Metode : Menyediakan scaffold komposit kitosan/hidroksiapatit/kolagen, kemudian merendam scaffold didalam simulated body fluid pada suhu 37 0C, selama 8 hari. Kemudian masing ndash; masing scaffold diangkat dan dikeringkan pada suhu ruang pada hari 0, 2, 4, 6, 8. Untuk diuji kekuatan tekan dan kekuatan tarik. Data yang diperoleh diolah dan dianalisa. Hasil : Variasi nilai kekuatan tekan dan kekuatan tarik dapat dihubungkan dengan beberapa hal , ukuran spesimen yang tidak seragam, komposisi scaffold, ukuran pori scaffold yang tidak sama dan adanya degradasi dari kandungan polimer. Kesimpulan : Scaffold kitosan/hidroksiapatit/kolagen tidak memiliki kekuatan tarik dan kekuatan tekan sebelum dan setelah perendaman masing ndash;masing hari dengan simulated body fluid.

ABSTRACTBackground The reconstruction of bone tissue defect is a major challenge for the oral and maxillofacial surgeon. The basic elements needed in a tissue engineering is a cell, scaffold matrix and stimulant molecules growth factors . How mechanical properties the scaffold of chitosan hydroxyapatite collagen production BATAN, Jakarta, has never been in research. Purpose Analyze the mechanical properties the scaffold of chitosan hydroxyapatite collagen from BATAN, Jakarta, before and after immersion in simulated body fluid for 8 days. Method Provides a composite scaffold of chitosan hydroxyapatite collagen, then soaking the scaffold in SBF at 37 0 C, for 8 days. Then each scaffold is removed and dried at room temperature on the day of 0, 2, 4, 6, 8. To test the compressive strength and tensile strength. The data obtained were processed and analyzed. Results Variations in the value of the compressive strength and tensile strength can be attributed to several things, the size of the specimen which is not the same, the composition of the scaffold, scaffold pore size is not the same and the degradation of the content polimer. Summary Scaffold chitosan hydroxyapatite collagen does not have differences the tensile strength and compressive strength before and after immersion with simulated body fluid."

""ABSTRAK"Insidensi trauma maksilofasial dipengaruhi oleh beberapa faktor seperti: budaya, latar belakang penduduk, ekonomi, dan kepadatan penduduk. Penelitian ini bertujuan untuk mengetahui insidensi kasus trauma maksilofasial yang terdapat di Rumah Sakit Umum Daerah Provinsi DKI Jakarta RSUD Tarakan, RSUD Koja, RSUD Cengkareng, RSUD Budhi Asih, RSUD Pasar Rebo, RSKD Duren Sawit, RSUD Kepulauan Seribu . Ditemukan 957 pasien trauma maksilofasial dan 138 fraktur maksilofasial yang dikelompokkan berdasarkan usia, jenis kelamin, penyebab dan lokasi fraktur. Kelompok usia 21-27 tahun adalah kelompok usia tertinggi dari trauma maksilofasial, jenis kelamin laki-laki 74,82 , Perempuan 25,18 dengan perbandingan 3:1. Penyebab trauma maksilofasial yang tertinggi adalah kecelakaan lalu lintas."

""ABSTRACT"Incidence of maxillofacial trauma affected by several factors culture, population background, economical status, and population density. This study aimed to determine the incidence of maxillofacial trauma occured in the General Hospital of DKI Jakarta RSUD Tarakan, RSUD Koja, RSUD Cengkareng, RSUD Budhi Asih, RSUD Pasar Rebo, RSKD Duren Sawit, RSUD Kepulauan Seribu . There is 957 patient with maxillofacial trauma cases and 138 patients with maxillofacial fractures cases by age, sex, cause and location of fracture. The age group of 21 27 years old is the highest group of maxillofacial trauma found, male 74.82 , 25.18 women with a ratio of 3 1. The cause of maxillofacial trauma were highest traffic accident."

"Gigi impaksi merupakan kondisi patologis dimana gigi mengalami kegagalan untuk erupsi secara sempurna pada rongga mulut sesuai posisi fungsionalnya. Tatalaksana untuk gigi molar 3 impaksi adalah odontektomi, dapat dilakukan dalam anestesi lokal maupun anestesi umum atau narkose (general anesthesia). Edema merupakan salah satu komplikasi yang dapat terjadi akibat adanya akumulasi cairan pada jaringan yang disebabkan karena pelepasan mediator inflamasi, vasodilatasi, dan peningkatan permeabilitas kapiler pembuluh darah pasca odontektomi gigi molar 3. Edema pasca odontektomi biasanya memuncak pada 48 jam pasca tindakan odontektomi, dan akan menurun pada hari ke 7 hingga hari ke 10 pasca odontektomi. 3D Scanner ekstra oral ini mampu menghasilkan pengukuran linear dan pengukuran volumetrik yang akurat karena mampu menampilkan pengukuran baik dari bidang aksial, sagital, dan koronal. Penelitian ini dilakukan di Rumah Sakit Universitas Indonesia (RSUI) dengan rentang waktu penelitian Januari 2024-Maret 2024. Berdasarkan analisa sampel pada penelitian ini memiliki responden terbanyak dengan interval usia 18 hingga 40 tahun. Scan pasien dilakukan pada hari pertama dilakukannya odontektomi (H0), hari ke-2 (H2) dan hari ke-7 (H7) sejak tindakan odontektomi dengan narkose dilaksanakan. Scan subjek dianalisis menggunakan software Simplify3D® 4.0 dan 3D Builder. 1. Berdasarkan hasil penelitian, terdapat perbedaan yang sangat signifikan (p<0.001) evaluasi edema pada wajah pasca odontektomi gigi molar tiga impaksi dengan narkose yang dinilai dengan 3D Scanner ekstra oral. Terjadi kenaikan pada hari ke-2 dibandingkan dengan hari ke-0, serta penurunan kembali di hari ke-7 bila dibandingkan dengan hari ke-2 hingga mendekati pengukuran awal di hari ke-0. Penelitian ini menjadi pilot study pengukuran dengan reliabilitas dan keakuratan tinggi menggunakan scanner 3D ekstraoral.

Impacted teeth are a pathological condition where teeth fail to erupt properly in the oral cavity in their functional position. The management for impacted third molars involves a procedure called odontectomy, which can be performed under local anesthesia or general anesthesia. Edema is one of the complications that may occur due to the accumulation of fluid in tissues caused by the release of inflammatory mediators, vasodilation, and increased capillary permeability post-odontectomy of third molar teeth. Edema post-odontectomy typically peaks at 48 hours after the procedure and decreases by days 7 to 10 post-odontectomy. Extraoral 3D scanner is capable of producing accurate linear and volumetric measurements because it can display measurements from axial, sagittal, and coronal planes. This study was conducted at the University of Indonesia Hospital (RSUI) within the timeframe of January 2024 to March 2024. Based on sample analysis in this study, the majority of respondents fell within the age range of 18 to 40 years old. Patient scans were performed on the day of odontectomy (H0), on day 2 (H2), and on day 7 (H7) following odontectomy with anesthesia. Subject scans were analyzed using Simplify3D® 4.0 and 3D Builder software. 1. According to the research findings, there was a very significant difference (p<0.001) in the evaluation of edema on the face post-odontectomy of impacted third molar teeth with general anesthesia as assessed by the extraoral 3D scanner. There was an increase on day 2 compared to day 0, followed by a decrease on day 7 compared to day 2, approaching the initial measurement on day 0. This study serves as a pilot study for measurements with high reliability and accuracy using an extraoral 3D scanner."
