Abstract

Regional odontodyplasia (RO) merupakan anomali yang terjadi secara lokal, nonherediter developmental abnormality dengan kerusakan parah pada pembentukan enamel, dentin serta pulpa. Gambaran radiografis menunjukkan kamar pulpa besar dengan lapisan enamel dan dentin yang sangat tipis serta penurunan densitas sedangkan ukuran gigi normal atau sedikit lebih kecil daripada normal sehingga tampilan gambaran tersebut tampak seperti “ghost teeth”. Kompleksitas abnormalitas yang membutuhkan visualisasi gambaran hubungan gigi dan skeletal dapat dilakukan dengan pemeriksaan Cone Beam Computed Tomography (CBCT). Laporankasus berikut memaparkan gambaran radiografik CBCT pasien RO melibatkan regio anterior kanan rahang atas dan insisivus sentral kiri rahang atas. Pasien anak laki-laki usia 8 tahun 8 bulan dengan gigi depan atas kanan permanen belum tumbuh. Pada panoramik reconstruction tampak kehilangan gigi 51, 52, 53 dan gigi 61 resorpsi akar mencapai 1/3 apikal. Benih gigi 11, 12, 13, 21 berukuran kecil dan belum erupsi. Diagnosis banding kasus ini adalah dentinogenesis imperfekta dan segmental odontomaxillary dysplasia. Perawatan yang dilakukan berupapembuatan gigi tiruan sebagian lepasan akrilik regio 51, 52, 53. RO yang melibatkan dua regio sangat jarang terjadi. Pada laporan kasus ini dilakukan evaluasi menggunakan CBCT dengan tampilan Multiplanar reformatted (MPR), panoramic Volume Rendering (VR) pada potongan axial, panoramic view, transaxial-sagittal, and 3D view sehingga dapat dilakukan evaluasi perkembangan benih gigi secara menyeluruh dalam segala aspek. Gambaran radiografik yang khas dari RO menunjukkan bahwa pemeriksaan radiografik merupakan metode diagnostik utama dalam menegakkan diagnosis yang penting dalam menentukan rencana perawatan yang tepat.

Abstract

Background: Several factors must be considered when selecting the appropriate field of view (FOV) and voxel size for good image quality on Cone Beam Computed-Tomography (CBCT). The purpose of this study is to determine the factors that must be considered in selecting the appropriate FOV and voxel size to achieve good image quality according to the purpose of the examination. Method: Articles in Q1 and Q2 journals published within the period from January 2016 to September 2021 were searched from Scopus and PubMed online using the keywords field of view/FOV in CBCT, voxel size in CBCT, and FOV and voxel size in CBCT. On the basis of the article selection criteria, 13 journals were included in the study. Also included in the study were several types of three-dimensional (3D) CBCT machines: Planmeca ProMax® 3D ProFaceTM, i-Cat Cone Beam 3D, Picasso Trio CBCT: Carestream unit® CS 9300 CBCT, and Accuitomo F17D 3D CBCT. Result: It is generally recommended that a 0.2 mm voxel size be used to detect periodontal disease, secondary caries, fractures, external resorption, and endodontic complications. Meanwhile, for root fractures with an intracanal metallic post and an anatomic isthmus in the root canal, a 0.1 mm voxel size is recommended to be used, and for evaluating the implant, 0.3 mm and 0.4 mm voxel sizes are recommended. Conclusion: It was found in the review that most of the selected studies recommended using the smallest FOV available in the CBCT unit to detect pathological conditions and important anatomical structures.
