Objectives
<p>To study residual ridge dimensions at edentulous first molar sites in relation to periodontal bone loss among cohorts of partially edentulous Asian Indian and Hong Kong Chinese subjects seeking tooth replacement.</p>
Materials and methods
<p>A total of 628 edentulous maxillary first molar sites were analyzed on Cone Beam Computed Tomography scans of 225 Asian Indian (I) and 232 Hong Kong Chinese (C) partially edentulous adults seeking tooth replacement. Age, ethnicity, gender, total tooth loss, the presence or absence of adjacent teeth, categories of periodontal status defined according to radiographic alveolar bone loss (P0: periodontal health, P1: incipient to moderate disease, P2: severe periodontal disease) and sinus membrane abnormalities were noted. Alveolar ridge height (<hi rend="fc">RH</hi>), widths at 1 and 3 mm from crest (<hi rend="fc">RW</hi>1; <hi rend="fc">RW</hi>3), and relative position of the bone crest (<hi rend="fc">RR</hi>) were measured.</p>
Results
<p>Prevalence of P2 status was most frequent in both cohorts(C: 50.4% I: 49.2%). P2 had lowest ridge heights; 13.1% C P2 and 14%I P2 had <hi rend="fc">RH</hi> < 2 mm. Sites with both <hi rend="fc">RH</hi> <8 mm and <hi rend="fc">RW</hi>1 < 6 mm occurred at 59%C P2 and 68%I P2. Sinus membrane abnormalities were most frequent in P2. Periodontal status and sinus membrane abnormality increased the odds of <hi rend="fc">RH</hi> <5 mm and <hi rend="fc">RH</hi> <8 mm more than 2‐fold; additionally, gender and ethnicity significantly impacted <hi rend="fc">RH</hi> <8 mm. Gender and adjacent tooth status significantly affected <hi rend="fc">RW</hi>1.</p>
Conclusion
<p>Incident advanced periodontal disease was common among Asian Indian and Hong Kong Chinese subjects seeking tooth replacement and associated with lower available bone heights. Ethnicity, gender, sinus membrane thickening affected available bone height in the subsinus region, while the presence of adjacent teeth‐ and age‐affected residual ridge width.</p></abstract><textClass><keywords><term xml:id="clr12292-kwd-0001">clinical assessment</term><term xml:id="clr12292-kwd-0002"><hi rend="fc">CT</hi> imaging</term><term xml:id="clr12292-kwd-0003">diagnosis</term><term xml:id="clr12292-kwd-0004">imaging</term><term xml:id="clr12292-kwd-0005">radiology</term></keywords><keywords rend="articleCategory"><term>Original Article</term></keywords><keywords rend="tocHeading1"><term>Original Articles</term></keywords></textClass><langUsage><language ident="en"></language></langUsage></profileDesc></teiHeader></istex:fulltextTEI></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="clr12292" 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.
