  • analisis gambaran complex odontoma pada radiografi panoramik panoramic radiograph analysis of complex odontoma
    Jurnal Kedokteran Gigi Universitas Padjadjaran, 2018
    Co-Authors: Fitri Angraini Nasution, Suhardjo Sitam
    Abstract:

    Pendahuluan: Odontoma merupakan tumor odontogenik yang memiliki sifat klinis jinak. Odontoma terdiri dari dua jenis yaitu compound dan complex odontoma . Perbedaan diantara keduanya adalah compound odontoma berbentuk seperti struktur gigi, sedangkan complex odontoma tersusun atas massa enamel dan dentin yang tidak teratur dan tidak memiliki kemiripan anatomi. Tujuan laporan kasus untuk menganalisis gambaran radiograf panoramik pada kasus complex odontoma. Laporan kasus: Pasien perempuan berusia 24 tahun datang ke klinik Bedah Mulut RSUD Arifin Achmad Pekanbaru dengan keluhan pembengkakan pada rahang bawah bagian kiri. Pembengkakan tidak disertai rasa sakit. Hasil pemeriksaan radiograf panoramik menunjukkan lesi radioopak homogen, well-defined yang dikelilingi halo radiolucent . Suspek radiodiagnosis adalah complex odontoma yang berhubungan dengan impaksi gigi permanen molar. Radiograf panoramik dapat digunakan untuk menganalisis gambaran complex odontoma. Simpulan: Gambaran radiografi complex odontoma umumnya radioopak homogen yang dikelilingi halo radiolucent dengan batas jelas ( well-defined, soft tissue capsule border ). Kata kunci: Complex odontoma, impaksi molar, tumor odontogenik. ABSTRACT Introduction: Odontomas are odontogenic tumour with benign clinical properties. Odontoma consists of two types, namely compound and complex odontoma. The difference between them is that the compound odontoma is shaped like a tooth structure, whereas complex odontoma is composed of an irregular mass of enamel and dentine with no anatomical resemblance. The purpose of this case report was to analyse the panoramic radiograph of complex odontoma cases. Case report: A 24-years-old female patient came to the Arifin Achmad Pekanbaru Oral Surgery Clinic with a complaint of swelling in the left mandibular. The swelling was not accompanied by pain. The panoramic radiograph result showed a homogeneous, well-defined radioopaque lesions surrounded by a halo radiolucent halo. Radiodiagnosis suspect was a complex odontoma associated with impaction of permanent molar teeth. Conclusion: Panoramic radiograph can be used to analyse complex odontoma images. Radiographic features of homogeneous complex odontoma are homogeneous Radiopaque surrounded by halo radiolucent with a well-defined, soft tissue capsule border. Keywords: Complex odontoma, molar impaction, odontogenic tumour.

  • detection of organ movement in cervix cancer patients using a fluoroscopic electronic portal imaging device and Radiopaque markers
    International Journal of Radiation Oncology Biology Physics, 2002
    Co-Authors: Robert S J P Kaatee, Manouk J J Olofsen, Marjolein Verstraate, S Quint, Ben J M Heijmen
    Abstract:

    Abstract Purpose: To investigate the use of a fluoroscopic electronic portal imaging device (EPID) and Radiopaque markers to detect internal cervix movement. Methods and Materials: For 10 patients with Radiopaque markers clamped to the cervix, electronic portal images were made during external beam irradiation. Bony structures and markers in the portal images were registered with the same structures in the corresponding digitally reconstructed radiographs of the planning computed tomogram. Results: The visibility of the markers in the portal images was good, but their fixation should be improved. Generally, the correlation between bony structure displacements and marker movement was poor, the latter being substantially larger. The standard deviations describing the systematic and random bony anatomy displacements were 1.2 and 2.6 mm, 1.7 and 2.9 mm, and 1.6 and 2.7 mm in the lateral, cranial-caudal, and dorsal-ventral directions, respectively. For the marker movement those values were 3.4 and 3.4 mm, 4.3 and 5.2 mm, 3.2 and 5.2 mm, respectively. Estimated clinical target volume to planning target volume (CTV-PTV) planning margins (≈11 mm) based on the observed overall marker displacements (bony anatomy + internal cervix movement) are only marginally larger than the margins required to account for internal marker movement alone. Conclusions: With our current patient setup techniques and methods of setup verification and correction, the required CTV-PTV margins are almost fully determined by internal organ motion. Setup verification and correction using Radiopaque markers might allow decreasing those margins, but technical improvements are needed.

  • composition property relationships for Radiopaque composite materials pre loaded drug eluting beads for transarterial chemoembolization
    Journal of Biomaterials Applications, 2015
    Co-Authors: Nancy Kilcup, Elena Tonkopi, Robert J Abraham, Daniel Boyd, S Kehoe
    Abstract:

    The purpose of this study was to synthesize and optimize intrinsically Radiopaque composite embolic microspheres for sustained release of doxorubicin in drug-eluting bead transarterial chemoembolization. Using a design of experiments approach, 12 Radiopaque composites composed of polylactic-co-glycolic acid and a Radiopaque glass (ORP5) were screened over a range of compositions and examined for radiopacity (computed tomography) and density. In vitro cell viability was determined using an extract assay derived from each composition against the human hepatocellular carcinoma cell line, HepG2. Mathematical models based on a D-Optimal response surface methodology were used to determine the preferred Radiopaque composite. The resulting Radiopaque composite was validated and subsequently loaded with doxorubicin between 0 and 1.4% (wt% of polylactic-co-glycolic acid) to yield Radiopaque composite drug-eluting beads. Thereafter, the Radiopaque composite drug-eluting beads were subjected to an elution study (up t...

  • Biodegradable and biocompatible Radiopaque iodinated poly-3-hydroxy butyrate: synthesis, characterization and in vitro/in vivo X-ray visibility

    Abstract:

    Hazer, Baki/0000-0001-8770-805XWOS: 000511700600016TARAMASCOPUSTARAMAWOSSome novel Radiopaque biodegradable and biocompatible iodinated polymers based on poly-3-hydroxy butyrate (PHB) were obtained. Following the attachment of diethanol amine to PHB, the hydroxyl ends were capped with 4-iodobenzoic acid and 2,3,5-tri-iodobenzoic acid. In this manner, tri-novel Radiopaque polymers were obtained. The resulting polymers were structurally characterized by NMR technique. They were evaluated with respect to their possible use as Radiopaque implant biomaterials indicating X-ray visibility in a noninvasive manner using routine X-ray absorption imaging techniques. These polymers exhibited good radiopacity with conventional imaging X-ray techniques in vivo. Additionally, biocompatibility of these iodinated polymers was also evaluated. There were no signs of infection or abscess formation on the surgical area. These novel Radiopaque PHBs should be promising biomaterials for a new-generation Radiopaque materials.Kapadokya University [KUN.2018-BAGP-001]; Bulent Ecevit University Research FundsBulent Ecevit University [BEU-2017-72118496-01]This work was supported by the Kapadokya University (#KUN.2018-BAGP-001) and Bulent Ecevit University Research Funds (#BEU-2017-72118496-01).
