Estimation of lesion progress in artificial root caries by swept source optical coherence tomography in comparison to transverse microradiography.
J Biomed Opt. 2011 Jul; 16(7): 071408 Natsume Y, Nakashima S, Sadr A, Shimada Y, Tagami J, Sumi Y This study aimed to investigate whether swept source optical coherence tomography (SS-OCT) could estimate the lesion depth and mineral loss quantitatively without the use of polarization sensitivity, and to examine a relationship between OCT data and … Continue reading »
Non-invasive quantification of resin-dentin interfacial gaps using optical coherence tomography: Validation against confocal microscopy.
Dent Mater. 2011 Jun 12; Bakhsh TA, Sadr A, Shimada Y, Tagami J, Sumi Y OBJECTIVES: Regardless of the cause, gap formation at the tooth-restoration interface may result in treatment failure; non-destructive assessment and monitoring of these defects are important. The aim of this in vitro study is to assess the tooth-restoration interface using a … Continue reading »
Non-destructive 3D imaging of composite restorations using optical coherence tomography: Marginal adaptation of self-etch adhesives.
J Dent. 2011 Apr; 39(4): 316-25Makishi P, Shimada Y, Sadr A, Tagami J, Sumi Y To investigate the potential use of swept-source optical coherence tomography (SS-OCT) as a new tool to evaluate marginal adaptation of composite restorations in class I cavities.Round-shaped class I cavities (3mm diameter×1.5mm depth) were prepared on buccal enamel of bovine teeth … Continue reading »
Validation of swept-source optical coherence tomography (SS-OCT) for the diagnosis of occlusal caries.
J Dent. 2010 Aug; 38(8): 655-65Shimada Y, Sadr A, Burrow MF, Tagami J, Ozawa N, Sumi Y In this laboratory study, we examined the use of a swept-source optical coherence tomography (SS-OCT) as a diagnostic tool for occlusal caries.One-hundred and eleven investigation sites of occlusal fissures were selected from 62 extracted teeth and examined visually … Continue reading »
