The purpose of this study was to assess the clinical and radiographic outcomes of a 1-minute application of full-strength Buckley's formocresol with concurrent hemostasis using the medicated cotton pledget in human primary teeth.
Using a retrospective chart review, clinical and radiographic data were available for 557 primary molars in 320 patients. Descriptive statistics and survival analysis were used to assess outcomes.
Overall clinical success, radiographic success, and cumulative 5-year survival rates were approximately 99%, 90%, and 87%, respectively. Internal root resorption (∼5%) and pulp canal obliteration (∼2%) were the most frequently observed radiographic failures. Thirty-nine teeth were extracted due to clinical and or radiographic failure. Mandibular molars were 6 times more prone to radiographic failure than maxillary molars.
Success rates for the modified technique are comparable to techniques that use the 5-minute diluted or full-strength solutions reported in the literature. This 1-minute full-strength formocresol technique is an acceptable alternative to published traditional techniques.
本研究旨在评估在人类乳牙中使用含药棉球同时止血的情况下，1分钟应用全强度巴克利甲醛甲酚的临床和影像学结果。
通过回顾性病历审查，获取了320例患者557颗乳牙的临床和影像学数据。使用描述性统计和生存分析来评估结果。
总体临床成功率、影像学成功率和5年累积生存率分别约为99%、90%和87%。牙根内吸收（约5%）和根管闭锁（约2%）是最常见的影像学失败情况。39颗牙齿因临床和/或影像学失败而被拔除。下颌磨牙发生影像学失败的可能性是上颌磨牙的6倍。
改良技术的成功率与文献中报道的使用5分钟稀释或全强度溶液的技术相当。这种1分钟全强度甲醛甲酚技术是已发表的传统技术的可接受替代方法。
