The purposes of this study were to evaluate the: effect of a 1-minute application of full-strength Buckley's formocresol with concur- rent hemostasis using the medicated cotton pledget in human primary teeth on their successors; and exfoliation times compared to the contralateral nonpulpotomized tooth.
Using a retrospective chart review, clinical and radiographic data were available for 557 primary molars in 320 patients.
There was no difference between treated and control teeth in the number of enamel defects of succedaneous teeth (P<.45). Approximately 66% exfoliated at the same time as their contralateral counterpart and approximately 29% exfoliated earlier (P<.001).
This 1-minute technique showed a tendency toward early exfoliation, but no effect on clinical management, and no increase in incidence of defects on succedaneous teeth was observed. The 1-minute full-strength formocresol technique may be considered an acceptable alternative to the 5-minute formocresol pulpotomy.
本研究的目的是评估：使用含药棉球对人类乳磨牙应用1分钟全强度巴克利氏甲醛甲酚并同时止血对其继承恒牙的影响；以及与对侧未进行牙髓切断术的牙齿相比的脱落时间。
通过回顾性病历审查，获得了320例患者557颗乳磨牙的临床和影像学数据。
治疗组和对照组恒牙釉质缺陷数量无差异（P<0.45）。约66%的牙齿与其对侧牙齿同时脱落，约29%的牙齿提前脱落（P<0.001）。
这种1分钟技术显示出早期脱落的趋势，但对临床处理无影响，且未观察到继承恒牙缺陷发生率增加。1分钟全强度甲醛甲酚技术可被视为5分钟甲醛甲酚牙髓切断术的可接受替代方法。
