We found pure primary supernumerary teeth in the maxillary right deciduous incisor region of a 3 year 11 month old girl. We reported the results of her oral and X-ray analysis results. We would like to report our findings on the results of her oral and X-ray analysis. 1) Two of the primary supernumerary teeth were found between the incisor and canine teeth in the right side of the primary dental arch, and their color, form and size were very similar to normal primary lateral incisor teeth. 2) We also found pure secondary supernumerary teeth by means of X-ray analysis. 3) We suggest that the permeability of the X-ray is important for the ascertainment of both primary and secondary supernumerary teeth by mean of X-ray analysis.
我们在一名3岁11个月大女孩的右上颌乳牙切牙区发现了单纯性原发性多生牙。我们报告了她的口腔及X线分析结果。我们想汇报关于她口腔及X线分析结果的发现。1）在乳牙牙弓右侧的切牙和尖牙之间发现了两颗原发性多生牙，它们的颜色、形态和大小与正常的乳牙侧切牙非常相似。2）我们还通过X线分析发现了单纯性继发性多生牙。3）我们认为，X线的穿透性对于通过X线分析确定原发性和继发性多生牙都很重要。
