The dimensions of the incisive fossae of 960 Negroid skulls were measured and the frequency of nasopalatine duct cysts in this material was determined. A random sample of 200 of the above skulls was radiographed under standardized conditions and the radiographic dimensions of the incisive fossae were compared statistically with their actual dimensions. Incisive fossa widths of greater than 6 mm were found in 148 specimens (15.3%), and anteroposterior dimensions of greater than 7 mm were found in 799 specimens (82.4%). Thirteen cysts were found. Radiographic measurements of incisive fossae were significantly different from those made on the skulls. Mean dimensions of the fossae in this sample were greater than those previously reported and there was a higher frequency of nasopalatine duct cysts.
对960个黑人颅骨的切牙窝尺寸进行了测量，并确定了该材料中鼻腭管囊肿的发生率。在标准化条件下，对上述200个颅骨的随机样本进行了X线摄影，并将切牙窝的X线摄影尺寸与其实际尺寸进行了统计学比较。发现148个标本（15.3%）的切牙窝宽度大于6mm，799个标本（82.4%）的前后径大于7mm。发现了13个囊肿。切牙窝的X线摄影测量结果与颅骨测量结果有显著差异。该样本中窝的平均尺寸大于先前报道的尺寸，且鼻腭管囊肿的发生率更高。
