The purposes of this retrospective chart review were to determine: (1) how primary molars in need of vital pulp therapy (VPT) have been treated over a period of four years at a university-based pediatric dental practice (UBP); and which treatments-indirect pulp therapy (IPT), formocresol pulpotomy (FCP), and ferric sulfate pulpotomy (FSP)-have been successful.
Electronic patient records (axiUm) that contained the procedure codes D3120 (pulp cap-indirect) or D3220 (therapeutic pulpotomy) were totaled by year. Visit records were queried again to identify treatment failures (i.e., extractions [D7140] or pulpectomy [D3221/D3240]). A total of 2,001 primary molar teeth were included in the study. Success was compared using a Kaplan-Meier analysis.
At the three-year follow-up, IPT had a 96.2 percent survival rate, FCP had a 65.8 percent survival rate, and FSP had a 62.9 percent survival rate (P<.0001).
Over a four-year period of time, IPT became the more commonly used vital pulp therapy treatment at a university-based pediatric dental practice and had a significantly better survival rate than FCP or FSP.
本回顾性病历审查的目的是确定：（1）在一所大学附属儿科牙科诊所（UBP），需要进行牙髓活力治疗（VPT）的乳磨牙在四年时间里是如何治疗的；以及哪些治疗方法——间接盖髓术（IPT）、甲醛甲酚牙髓切断术（FCP）和硫酸铁牙髓切断术（FSP）——是成功的。
按年份汇总包含程序代码D3120（间接盖髓）或D3220（治疗性牙髓切断术）的电子病历（axiUm）。再次查询就诊记录以确定治疗失败情况（即拔牙[D7140]或根管治疗[D3221/D3240]）。本研究共纳入2001颗乳磨牙。使用Kaplan-Meier分析比较成功率。
在三年随访时，IPT的存活率为96.2%，FCP的存活率为65.8%，FSP的存活率为62.9%（P<0.0001）。
在四年时间里，IPT成为大学附属儿科牙科诊所更常用的牙髓活力治疗方法，其存活率明显高于FCP或FSP。
