Abstract
Abstract: Purpose: Individuals with developmental deformities of the jaws may be less efficient at chewing food. Previous studies have reported masticatory deficiency in patients with such deformities. This study was designed to detect any changes in masticatory performance that accompany orthognathic surgery. Materials and Methods: Masticatory performance was tested in 18 patients with various jaw deformities before application of orthodontic appliances and 2 to 3 years after surgical correction of their malocclusion. A control group was tested at three 6-month intervals. The subjects chewed carrots and masticatory performance was measured using a standard sieve technique. The Rosin-Rammler equation was used to calculate the median particle size and broadness index of each set of carrots. The number of chewing cycles required for each subject to swallow one piece of carrot was also recorded. Results: A statistically significant difference in median particle size between patients and controls was found both preoperatively and postoperatively (P < .05), but no difference in median particle size or broadness index was seen between trials for controls or patients (P > .05). Conclusion: It was concluded that before surgery patients have a lower level of performance than controls and surgical correction of the malocclusion does not significantly enhance performance.

The number of chewing cycles required for each subject to swallow one piece of carrot was also recorded. Results: A statistically significant difference in median particle size between patients and controls was found both preoperatively and postoperatively (P < .05), but no difference in median particle size or broadness index was seen between trials for controls or patients (P > .05). Conclusion: It was concluded that before surgery patients have a lower level of performance than controls and surgical correction of the malocclusion does not significantly enhance performance.</p></abstract></profileDesc><revisionDesc><change when="1995">Published</change></revisionDesc></teiHeader></istex:fulltextTEI><json:item><extension>txt</extension><original>false</original><mimetype>text/plain</mimetype><uri>https://api.istex.fr/document/14E66B2095AFD6C86499E728FF8A07E7F90AEC43/fulltext/txt</uri></json:item></fulltext><metadata><istex:metadataXml wicri:clean="Elsevier, elements deleted: tail"><istex:xmlDeclaration>version="1.0" encoding="utf-8"</istex:xmlDeclaration><istex:docType PUBLIC="-//ES//DTD journal article DTD version 4.5.2//EN//XML" URI="art452.dtd" name="istex:docType"></istex:docType><istex:document><converted-article version="4.5.2" docsubtype="fla"><item-info><jid>YJOMS</jid><aid>95903313</aid><ce:pii>0278-2391(95)90331-3</ce:pii><ce:doi>10.1016/0278-2391(95)90331-3</ce:doi><ce:copyright type="unknown" year="1995"></ce:copyright></item-info><head><ce:article-footnote><ce:label>☆</ce:label><ce:note-para>Received from the University of Texas Southwestern Medical Center, Dallas, TX.</ce:note-para></ce:article-footnote><ce:article-footnote><ce:label>☆☆</ce:label><ce:note-para>This research was supported by a grant from the American Association of Oral and Maxillofacial Surgeons.</ce:note-para></ce:article-footnote><ce:dochead><ce:textfn>Clinical article</ce:textfn></ce:dochead><ce:title>A longitudinal study of changes in masticatory performance of patients undergoing orthognathic surgery</ce:title><ce:author-group><ce:author><ce:given-name>Hooman M</ce:given-name><ce:surname>Zarrinkelk</ce:surname><ce:degrees>DDS</ce:degrees><ce:cross-ref refid="FN1"><ce:sup>∗</ce:sup></ce:cross-ref></ce:author><ce:author><ce:given-name>Gaylord S</ce:given-name><ce:surname>Throckmorton</ce:surname><ce:degrees>PhD</ce:degrees><ce:cross-ref refid="FN2"><ce:sup>†</ce:sup></ce:cross-ref></ce:author><ce:author><ce:given-name>Edward</ce:given-name><ce:surname>Ellis</ce:surname><ce:suffix>III</ce:suffix><ce:degrees>DDS, MS</ce:degrees><ce:cross-ref refid="COR1"><ce:sup>1</ce:sup></ce:cross-ref><ce:cross-ref refid="FN2"><ce:sup>‡</ce:sup></ce:cross-ref></ce:author><ce:author><ce:given-name>Douglas P</ce:given-name><ce:surname>Sinn</ce:surname><ce:degrees>DDS</ce:degrees><ce:cross-ref refid="FN4"><ce:sup>§</ce:sup></ce:cross-ref></ce:author><ce:correspondence id="COR1"><ce:label>1</ce:label><ce:text>Address correspondence and reprint requests to Dr Ellis: Division of Oral and Maxillofacial Surgery, University of Texas Southwestern Medical Center, 5323 Harry Hines Blvd, Dallas TX 75235-9109.</ce:text></ce:correspondence><ce:footnote id="FN1"><ce:label>∗</ce:label><ce:note-para>Research Fellow, Department of Oral and Maxillofacial Surgery.</ce:note-para></ce:footnote><ce:footnote id="FN2"><ce:label>†</ce:label><ce:note-para>Associate Professor, Department of Cell Biology and Neuroscience.</ce:note-para></ce:footnote><ce:footnote id="FN4"><ce:label>§</ce:label><ce:note-para>Professor and Chairman, Department of Oral and Maxillofacial Surgery.</ce:note-para></ce:footnote></ce:author-group><ce:abstract><ce:section-title>Abstract</ce:section-title><ce:abstract-sec><ce:simple-para><math altimg="si1.gif"><unl type="bar">Purpose:</unl></math> Individuals with developmental deformities of the jaws may be less efficient at chewing food.
