不同方法对口腔前庭沟深度测量的一致性研究

The consistency studyon different methods of oral vestibular groove depth measurements

目的评价4种口腔前庭沟深度(oral vestibular groove depth,OVGD)测量方法的一致性。方法3名检查者测量16例受试者16、14、11、46、44、41六个牙位的口腔前庭沟深度,均采用4种测量方法:硅橡胶模型测量(silicone rubber mold mea⁃surment,SMM)、藻酸盐模型测量(alginate mold,AMM)、口内直接测量(intra⁃oral direct measurement,IDM)和口腔扫描测量(oral scan measurements,OSM)。结果3名检查者间的一致性接近完美(ICC=0.87),4种测量方法间的一致性为一般(ICC=0.49);4种测量方法的结果由大到小依次为IDM>SMM>OSM>AMM;Bland⁃Altman图显示检查者之间一致性良好,测量方法之间一致性差。结论在4种口腔前庭沟深度测量方法中,检查者对结果几乎没有影响,不同测量方法得到的结果有差异。

Objective To study the consistencyamong four methods for measuring oral vestibular groove depth(OVGD).Methods Sixteen subjects were selected,and four measuring methods were used:silicone rubber mold measurement(SMM),alginate mold meas⁃urement(AMM),intra⁃oral direct measurement(IDM),and oral scan measurement(OSM).Three examiners(A,B,C)measured the vestibular groove depth of 16,14,11,46,44,and 41 tooth positions respectively.Results The consistency among the three examin⁃ers was nearly perfect(ICC=0.87),and the consistency among the four measuring methods was moderate(ICC=0.49).Results of the four measuring methods were IDM>SMM>OSM>AMM from the largest to the smallest.Bland⁃Altman plots showed good consistency a⁃mong examiners and poor consistency among measuring methods.Conclusion Among the four methods of measuring oral vestibular groove depth,examiners have little influence on the results,and the results obtained by different methods are different.
