Objectives
<p>The objective of this study was to investigate the stability of voxel values from cone‐beam <hi rend="fc">CT</hi> (<hi rend="fc">CBCT</hi>) using a flat panel detector in changing surrounding circumstances mimicking clinical situations.</p>
Materials and methods
<p>Seven hydroxyapatite (<hi rend="fc">HA</hi>) rods (0, 40, 80, 120, 160, 199, and 239 mg Ca/cm<hi rend="superscript">3</hi>) were set in a 16 cm diameter water phantom and scanned with <hi rend="fc">CBCT</hi> (FineCube) and also with multislice <hi rend="fc">CT</hi> (<hi rend="fc">MSCT</hi>) used as reference. The voxel values from <hi rend="fc">CBCT</hi> were measured by the obtained images with OsiriX software (<ref type="url">http://www.osirix-viewer.com</ref>), and compared with the <hi rend="fc">CT</hi> numbers from <hi rend="fc">MSCT</hi>. We examined the correlation between the voxel values and the <hi rend="fc">HA</hi> contents, the variance of voxel values, and the influence of changing surrounding circumstances on the voxel values.</p>
Results
<p>The voxel values from <hi rend="fc">CBCT</hi> were different from the <hi rend="fc">CT</hi> numbers from <hi rend="fc">MSCT</hi>, but there was a linear Pearson correlation between the voxel values and the <hi rend="fc">HA</hi> contents. The voxel values were greatly influenced when the samples were scanned surrounded in air. However, the voxel values were not affected significantly in the existence of materials simulating oral hard tissues and/or a metal core post.</p>
Conclusions
<p>There was a linear correlation between the voxel values of <hi rend="fc">CBCT</hi> and the contents of <hi rend="fc">HA</hi> rod samples. Our study indicated that it might be possible to evaluate bone mineral content<hi rend="fc">(BMC)</hi> from the voxel values of <hi rend="fc">CBCT</hi> for dental implant treatment.</p></abstract><textClass><keywords><term xml:id="clr2420-kwd-0001">bone mineral content</term><term xml:id="clr2420-kwd-0002">computed tomography</term><term xml:id="clr2420-kwd-0003">cone‐beam</term><term xml:id="clr2420-kwd-0004">dental implant</term><term xml:id="clr2420-kwd-0005">flat panel detector</term></keywords><keywords rend="articleCategory"><term>Original Research</term></keywords><keywords rend="tocHeading1"><term>Original Articles</term></keywords></textClass><langUsage><language ident="en"></language></langUsage></profileDesc></teiHeader></istex:fulltextTEI><json:item><extension>txt</extension><original>false</original><mimetype>text/plain</mimetype><uri>https://api.istex.fr/document/849C9F16EF5C73589E5F8E9600BFB512E0BC8B2D/fulltext/txt</uri></json:item></fulltext><metadata><istex:metadataXml wicri:clean="Wiley, elements deleted: body"><istex:xmlDeclaration>version="1.0" encoding="UTF-8" standalone="yes"</istex:xmlDeclaration><istex:document><component type="serialArticle" version="2.0" xml:id="clr2420" xml:lang="en"><header><publicationMeta level="product"><doi origin="wiley" registered="yes">10.1111/(ISSN)1600-0501</doi><issn type="print">0905-7161</issn><issn type="electronic">1600-0501</issn><idGroup><id type="product" value="CLR"></id></idGroup><titleGroup><title sort="CLINICAL ORAL IMPLANTS RESEARCH" type="main">Clinical Oral Implants Research</title><title type="short">Clin.
