The depth of the lingual fossa in permanent incisors of Norwegians (plaster casts and extracted teeth) was studied. In the plaster casts the depth of the lingual fossa in the right side incisors was (in mm): I,sup=0.51,I(2)sup= 0.30, I(1)inf =0.07 and I (2)inf =0.08. For 1(1)sup significant bilateral asymmetry was found (p<0.00l). All incisors were positively correlated in the depth of the lingual fossa, mandibular higher than maxillary. In both jaws centrals were better correlated across the midline than laterals, and centrals to laterals were less correlated than centrals to centrals and laterals to laterals. Interjaw correlations of 1(1)sup were higher than interjaw correlations with I(2)sup. Dental field theory is confirmed: The upper lateral and lower central were the most variable incisors in each jaw for lingual fossa depth. The values for this trait in Norwegians are within the Caucasoid range.
本文研究了挪威人（石膏模型和拔出的牙齿）恒切牙舌窝的深度。在石膏模型中，右侧切牙舌窝的深度（以毫米计）为：I，sup=0.51，I（2）sup=0.30，I（1）inf=0.07 和 I（2）inf=0.08。对于 1（1）sup，发现了明显的双侧不对称性（p<0.001）。所有切牙的舌窝深度均呈正相关，下颌切牙高于上颌切牙。在上下颌中，中切牙的中线间相关性优于侧切牙，而中切牙与侧切牙的相关性低于中切牙与中切牙、侧切牙与侧切牙的相关性。1（1）sup 的颌间相关性高于 I（2）sup 的颌间相关性。牙区理论得到证实：在上颌外侧和下颌中央，每个颌的切牙中舌窝深度的变异性最大。挪威人的这些特征值在白种人范围内。
