Abstract The aim of this study was to determine the diagnostic accuracy swept‐source optical coherent tomography (SS‐OCT) in detecting and estimating depth proximal caries posterior teeth vivo. SS‐OCT images bitewing radiographs were obtained from 86 surfaces 53 patients. Six examiners scored locations according a lesion scale (0–4) using radiographs. results compared with clinical observations after treatment. could detect presence tomograms that synthesized based on backscatter signal...
Abstract Objectives This study compared the silicone replica method with swept-source optical coherence tomography (SS-OCT) to analyze marginal adaptation and investigated effect of light incidence angle SS-OCT on measurement precision. Materials methods A typodont-prepared mandibular right first molar was scanned using an intraoral scanner (Trios 3). Fourteen crowns were fabricated from CAD/CAM resin blocks (Katana Avencia P) a 5-axis milling machine (DWX-50). Marginal at buccal, lingual,...
Internal adaptation of restorations to the cavity wall is one important topics in clinical dentistry. The purpose this study was investigate possibility utilize non-invasive tomographic imaging system for teaching importance at dental school pre-clinical training. Swept-source optical coherence tomography (SS-OCT) used detection marginal and internal defects composite resin as an educational device. Class 1 2 melamine molar tooth were assigned students prepared during skill test, SS-OCT...
(1) Background: Dental caries, if diagnosed at the initial stage, can be arrested and remineralized by a non-operative therapeutic approach preserving tooth structure. Accurate reproducible diagnostic procedure is required for successful management of incipient caries. The aim this study was to evaluate accuracy 3D swept-source optical coherence tomography (3D SS-OCT) enamel caries smooth surface lesion with remineralization. (2) Methods: Forty-seven surfaces 24 extracted human teeth visibly...
The first objective was to determine if dual-curing of resin cement with reduced light could affect interfacial adaptations zirconia restoration. second examine whether type and pretreatment method universal adhesive affected adaptation. final compare the polymerization degree under different reduced-light conditions.Inlay cavities were prepared on extracted third molars. Translucent restorations milled using Katana UTML (Kuraray Noritake) in three groups restoration thicknesses 1, 2, 3 mm,...

歯科医療現場における齲蝕の診断は困難を伴い,病変の深さや拡がりを正確に行う非侵襲的な画像表示方法の開発が望まれている.歯科用X線写真の初期齲蝕に対する感度は低く,透過像として検出できるのは象牙質内部まで深く進行している病変であることが多い.本研究は光干渉断層計(OCT)を用いた齲蝕の診断精度の検証を目的とし,in vitroおよびin vivo実験を行った.平滑面齲蝕,咬合面齲蝕,隣接面齲蝕ならびにコンポジットレジン修復の窩底部の齲蝕に対するSS-OCTの感度,特異度,受信者動作特性曲線の面積を計測し,視診またはX線写真の結果と比較した.SS-OCTの断層画像では,齲蝕病変部を輝度の上昇によって表示することができた.厚さ2 mmまでのコンポジットレジン修復窩底部の齲蝕も明るく表示され,健全な窩底象牙質と区別することができた.
Optical coherence tomography （OCT） is a non-destructive, non-invasive diagnostic method that uses near-infrared light, which considered to be harmless the human body. An OCT system includes an interferometer illuminates light and photodetector detects backscattered obtained from inside subject obtain precise tomographic images of tissue. has recently been used in dental-plaque studies measure plaque thickness morphology. Reports on observation biofilms: Xi C. et al. for high-resolution...
Purpose: Optical coherence tomography (OCT) is an imaging device that can create cross-sectional images of tooth structure. This study evaluated the diagnostic performance dental OCT system for occlusal caries in a real clinical situation.
Introduction: Swept-source optical coherence tomography （SS-OCT） is a new modality for noninvasively capturing cross-sectional images of not only biological structures but also any objects that are transparent to near-infrared light. With no exposure radiation, SS-OCT can be used safely even pregnant women and children. Features: The center wavelength 1,310nm the sweep range 110nm. has low extinction enamel enables observation deep internal structures. However, as it does penetrate full...
