单侧第三磨牙伸长患者翼外肌的MRI图像纹理分析研究
MRI image texture analysis of lateral pterygoid muscle in patients with unilateral over-erupted third molar
摘要
Abstract
Objective:To evaluate the changes of lateral pterygoid muscle in patients with unilateral over-erupted third molar by MRI image texture analysis and to clarify the correlation between unilateral over-erupted third molar and lateral pterygoid muscle.Methods:A total of 28 patients with unilateral over-erupted third molar,were enrolled in the outpatient clinic of the First Affiliated Hospital&Stomatological Hospital of Xinjiang Medical University from October 2020.According to the over-erupted side of the unilateral third molar,the patients were divided into two groups:the over-erupted side group and the non-over-erupted side group.The gray level co-occurrence matrix(GLCM)was used to measure the texture parameters of lateral pterygoid muscle in closed position,including angular second moment,contrast,correlation,inverse difference mo-ment and entropy,to compare the changes of lateral pterygoid muscle between over-erupted side group and non-over-erupted side group in patients with unilateral over-erupted third molar.Results:There was statistically significant in angular second moment,contrast,inverse difference moment and entropy of lateral pterygoid muscle between the over-erupted side group and the non-over-erupted side group(P<0.05).The area under the ROC curve(area under the curve,AUC)of entropy for evalua-ting the changes of lateral pterygoid muscle in patients with unilateral over-erupted third molar was 0.702,the Yoden index was 0.429,and the best truncation value was 7.565.The sensitivity and specificity of evaluating lateral pterygoid muscle changes were 64.3％and 78.6％.Conclusion:The texture parameter of entropy can be used to evaluate the changes of later-al pterygoid muscle in patients with unilateral over-erupted third molar.关键词
