The aim of this trial was to compare clinical and radiographic success rates of direct pulp capping (DPC) using a novel biomaterial called Calcium Enriched Mixture (CEM) cement versus Mineral Trioxide Aggregate (MTA) in primary molar teeth.
In this randomized clinical trial 42 deciduous molars in 21 patients who had at least two teeth requiring DPC, were treated. The enrolled patients were between 5-8 years. The molar teeth were randomly divided into two experimental groups. Patients and operators were blinded. The teeth were anaesthetized, caries were removed and after pinpoint exposure of dental pulp, haemostasis was achieved. The exposure points were capped with MTA or CEM cement. All teeth were restored with amalgam. Patients were recalled for the 6-month follow up. Statistical analysis was carried out using McNemar test.
Thirty-eight teeth were available for follow up (19 in each group). The radiographic evaluations did not show failure in experimental groups; however, in clinical examinations one sinus tract was found in CEM cement group. Clinical success rates in CEM cement and MTA groups were 94.8% and 100%, respectively. Dentinal bridge formation was not observed in the two experimental groups.
There is no significant difference between treatment outcomes of direct pulp capping with either CEM cement or MTA; therefore, both biomaterials can be used successfully for DPC in primary molar teeth.
本试验的目的是比较在乳磨牙中使用一种名为富钙混合物(CEM)粘固粉的新型生物材料与三氧化矿物凝聚体(MTA)进行直接盖髓术(DPC)的临床成功率和影像学成功率。
在这项随机临床试验中,对21例至少有两颗牙齿需要进行直接盖髓术的患者的42颗乳磨牙进行了治疗。入选患者年龄在5至8岁之间。将乳磨牙随机分为两个试验组。患者和操作人员均不知情。对牙齿进行麻醉,去除龋坏组织,在牙髓点状暴露后实现止血。暴露点用MTA或CEM粘固粉覆盖。所有牙齿均用银汞合金修复。对患者进行为期6个月的随访。使用McNemar检验进行统计分析。
38颗牙齿可供随访(每组19颗)。影像学评估未显示试验组有失败情况;然而,在临床检查中,CEM粘固粉组发现一个窦道。CEM粘固粉组和MTA组的临床成功率分别为94.8%和100%。两个试验组均未观察到牙本质桥形成。
使用CEM粘固粉或MTA进行直接盖髓术的治疗结果之间无显著差异;因此,这两种生物材料均可成功用于乳磨牙的直接盖髓术。
