In the context of a study of the life-spans of primary teeth subjected to formocresol pulpotomy, 152 such teeth were compared with the corresponding teeth on the contralateral sides. The life-span of each tooth was determined by registration of the time of exfoliation or extraction. In addition, data were collected concerning factors which may influence the life-spans of teeth. The principal conclusions are: There was no significant difference in life-spans between primary teeth with or without pulpotomy. Premature loss due to extraction exerted virtually no influence on the mean life-span of primary teeth, regardless of whether a pulpotomy had been performed. There was no significant difference in the number of extractions of primary teeth with or without a formocresol pulpotomy. There was no significant difference in the mean life-span between primary teeth with vital and those with nonvital pulp at the time of formocresol pulpotomy.
在一项关于接受甲醛甲酚牙髓切断术的乳牙寿命的研究中，将152颗这样的牙齿与其对侧相应的牙齿进行了比较。每颗牙齿的寿命通过记录脱落或拔除时间来确定。此外，收集了有关可能影响牙齿寿命的因素的数据。主要结论如下：接受或未接受牙髓切断术的乳牙在寿命上没有显著差异。无论是否进行了牙髓切断术，因拔除导致的过早脱落对乳牙的平均寿命几乎没有影响。接受或未接受甲醛甲酚牙髓切断术的乳牙在拔除数量上没有显著差异。在进行甲醛甲酚牙髓切断术时，牙髓活力正常的乳牙与牙髓无活力的乳牙在平均寿命上没有显著差异。
