The purpose of the present study was to determine reproducibility of the photographic technique, intra- and inter-examiner reliability of the moiré method for investigating tooth and palatal morphology as well as the agreement between the moiré method and the palatometer in measuring palatal height. Intraclass correlation coefficients (ICC) of 0.88 to 0.95 for three separate photographs for each of the same 40 casts taken by three examiners and measured by a single examiner exhibited high reproducibility of the photographic technique. For studying tooth morphology, the moiré lines were counted from the cusp tips to the mesiobuccal and distolingual fossae. ICC of 0.92 to 0.99 with 95% confidence limits for triple measurements and Pearson correlation coefficients of 0.92 to 1.00 for double measurements showed high intra- and inter-examiner consistency, respectively. For palatal height at the level of the first maxillary molars ICC with 95% confidence limits for triple measurements was 0.98 and correlation coefficient between two examiners 0.98, respectively. Correlation coefficients between the moiré method and the palatometer were also high, with a value of 0.98. In summary, with careful calibration before use, the moiré method proved to be useful and reliable in studying tooth and palatal morphology.
本研究的目的是确定摄影技术的可重复性、用于研究牙齿和腭部形态的云纹法在检查者内部和检查者之间的可靠性，以及云纹法与腭高测量仪在测量腭高方面的一致性。由三名检查者对40个相同模型中的每个模型分别拍摄三张照片，并由一名检查者进行测量，组内相关系数（ICC）为0.88至0.95，表明摄影技术具有较高的可重复性。为了研究牙齿形态，从牙尖到近中颊侧和远中舌侧窝计数云纹线。三次测量的ICC为0.92至0.99，置信区间为95%，两次测量的Pearson相关系数为0.92至1.00，分别表明检查者内部和检查者之间具有较高的一致性。在上颌第一磨牙水平处的腭高，三次测量的ICC（置信区间为95%）为0.98，两名检查者之间的相关系数为0.98。云纹法与腭高测量仪之间的相关系数也很高，为0.98。总之，在使用前进行仔细校准后，云纹法在研究牙齿和腭部形态方面被证明是有用且可靠的。
