研究者暗示腭皱对每个人来说都是独特的。然而，这些研究者对于法律的鉴定是否可以仅仅基于腭皱有不同意见。以前的研究使用了较差的复制材料，可能没有考虑到生长、拔牙、腭部扩张或这些因素的组合的影响。无意中使用其他特征的石膏，如牙齿，无牙嵴形态，肌肉附着，前庭深度，或这些的一些组合，以帮助识别，可能会影响他们的结果。本研究的目的是确定是否腭皱可以依赖于识别。25例正畸病例被选择与治疗前和治疗后的石膏;正畸治疗已经采取了18至60个月。随机选择100名演员作为变量。所有的模型都被修剪，以便除去硬腭的皱褶区域以外的所有区域。25个正畸后的模型被分散在100个随机选择的模型中。9名研究人员获得了25个正畸前的石膏模型，并要求将其与其他125个石膏模型进行比较，以寻找可能的匹配。收集了正确匹配百分比和比较所需时间的数据。每组正畸前和正畸后的石膏模型由8名研究者正确识别（100%），其余研究者正确匹配25个石膏模型中的22个（88%）。得出了这些结论。（250字处删节）
Investigators have implied that palatal rugae are unique to each individual. However, these researchers have disagreed as to whether or not legal identification could be based solely on palatal rugae. Previous studies used poor duplicating materials and may not have considered the effects of growth, extractions, palatal expansion, or some combination of these. The inadvertent use of other features of the cast, such as teeth, edentulous ridge morphology, muscle attachments, vestibular depth, or some combination of these, to aid in the identification, may have influenced their results. The purpose of this investigation was to determine if palatal rugae can be relied upon for identification. Twenty-five orthodontic cases were selected with pre- and post-treatment casts; orthodontic treatment had taken eighteen to sixty months. One hundred casts were randomly selected as variables. All casts were trimmed so that all areas except for the rugae area of the hard palate were removed. The twenty-five post-orthodontic casts were dispersed within 100 randomly selected casts. Nine investigators were given the twenty-five pre-orthodontic casts and asked to compare them to the other one hundred and twenty-five casts for possible matches. Data were collected as to percentage of correct matches and time required for comparison. Each set of pre- and post-orthodontic casts was properly identified (100%) by 8 investigators, and the remaining investigator correctly matched 22 out of 25 casts (88%). These conclusions were drawn.(ABSTRACT TRUNCATED AT 250 WORDS)
