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.
期刊介绍:
Cessation. The Revista Odonto Ciência is a peer-reviewed journal published online (ISSN 1980-6523), four times per year, supported by the Pontifical Catholic University of Rio Grande do Sul – Dental School since 1986. 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.
