Relationships between MRI image changes of lateral pterygoid muscle, disc position and condylar mobility in Class II patients / 中华口腔医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the relationships between MRI image changes of lateral pterygoid muscle (LPM), disc position and condylar mobility.</p><p><b>METHODS</b>Twenty Class II patients were chosen and MRI images of LPM were taken. The relationships between MRI image changes of LPM, disc position and condylar mobility were analyzed.</p><p><b>RESULTS</b>The rate of MRI image changes of LPM in Class II patients was about 45%. No significant correlations were found between MRI image changes of LPM, condylar mobility and disc position.</p><p><b>CONCLUSIONS</b>MRI image changes of LPM in Class II patients was common but no significant correlations were found between MRI image changes of LPM, condylar mobility and disc position.</p>
