Abstract

OBJECTIVE: To investigate the pulpal response to direct pulp capping in healthy human teeth with Portland cement (PC) as against mineral trioxide aggregate (MTA) as control.METHODS: Forty healthy human third molars indicated for extraction were randomly divided into two groups: PC and MTA. The teeth had iatrogenic pulp exposed and direct pulp capping with PC or MTA. After 1, 7, 14 and 21 days, the teeth were extracted and prepared for histological examination and bacterial detection. The Mann-Whitney test was applied for statistical analysis (p < 0.05).RESULTS: The MTA presented higher capacity to form of dentin bridges at 14- and 21-day intervals (p < 0.05). However, no significant statistical difference was found between the groups at all evaluated intervals (p > 0.05) for the response variables of inflammatory cells, soft tissue organization and bacterial staining.CONCLUSION: The PC has a biocompatibility equivalent to the MTA but with a lower capacity to form of dentin bridges. Therefore, MTA should be the material of choice for direct pulp capping.

人牙髓对硅酸盐水泥和MTA的反应

目的：研究硅酸盐水泥（PC）直接盖髓对健康人牙齿的牙髓反应，并与三氧化二矿物聚集体（MTA）作对照。方法：将40颗健康人第三磨牙随机分为PC组和MTA组。牙齿暴露于医源性牙髓，并用PC或MTA直接盖髓。在1、7、14和21天后，取出牙齿并准备进行组织学检查和细菌检测。应用Mann-Whitney检验进行统计分析（p<0.05）。结果：MTA在14天和21天的时间间隔内表现出更高的牙本质桥形成能力（p<0.05），但在炎症细胞、软组织组织组织和细菌染色的反应变量方面，两组在所有评估时间间隔内没有发现显著的统计学差异（p>0.05）。结论：PC具有与MTA相当的生物相容性，但形成牙本质桥的能力较低。因此，MTA应该是直接盖髓的首选材料。

Its abbreviation is Rev Odonto Cienc, which should be used in references, bibliographic legends, and footnotes. The Revista Odonto Ciência is an international scientific journal dedicated to provide a forum for academics, researchers, and practitioners to communicate relevant basic, clinical, education, and epidemiological studies in Dentistry and related fields. The Journal seeks to publish articles on new conceptual models, innovative technology, alternative procedures or treatment to reduce disease burden in the general population or specific groups, thus contributing to translating science into practice and social development. Contributions falling into the following categories will be considered for publication: 1) original research reports of basic and applied oral sciences, epidemiological, and education studies; 2) review article; 3) case report. The Revista Odonto Ciência only accepts manuscripts written in English. Manuscripts submitted to this journal should not have been published before nor have publication pending elsewhere.
