Abstract
Introduction Central carious dentine can be covered by a layer of Vitrebond™ in the treatment of deep carious lesions, where after the tooth can be restored with composite as usual. The treatment is called indirect pulp capping. At the Centre for Dentistry and Oral Health in Groningen, Vitrebond™ is used as a material for indirect pulp capping. Mineral trioxide aggregate (MTA) could be used as a material for direct pulp capping. MTA presented good results in a randomized controlled trial as a material for indirect pulp capping. The aim of the indirect pulp capping is to protect the pulp for infiltrating bacteria, as well as give the pulp the change to clean up the already presented bacteria and to heal. A material used for indirect pulp capping should therefore adapt to the dentine in such a manner that bacteria could not pass. In the literature there are different researches about adaptation, where it is defined in different ways. In this Systematic Review it is determined that the gap between the applied material and dentine may not be greater than 0.2μm for good adaptation. This is the size of the smallest bacterium. The dentine tubules should be filled for an ideal seal. The tubules near the pulp have a diameter of 2.5μm. In the literature researches about penetration report in penetration/no penetration. In this Systematic Review it is determined that the material for indirect pulp capping should be able to penetrate into dentine tubules to any extend. Aim A Systematic Review will be accomplished, where results about adaptation and penetration of MTA and Vitrebond™ to dentine and in dentine tubules will be assembled. The results will be compared and a decision for the most appropriate material for indirect pulp capping will be made. Materials and methods The Systematic Review was performed using the PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). A search was conducted in the databases of The National Center for Biotechnology Information (NCBI, PubMed), The Cochrane Library, Embase® and the Web of Science™. 245 studies where found that where published before June 10, 2016, and of these, 19 were included. The results were compared and a decision for the most appropriate material for indirect pulp capping could be made. Results The gaps between MTA and Vitrebond™ and the dentine are greater than 0.2μm. The results for penetration of MTA into the dentine tubules are contradictory. MTA can and cannot penetrate into the tubules according to three studies. Vitrebond™ can penetrate into the tubules. Discussion According to the results about adaptation and penetration of MTA and Vitrebond™ to and into dentine, a decision cannot be made for what material is more appropriate for indirect pulp capping. Other researches about adaption are not appropriate for describing the adaptation to dentine precisely. Conclusion Instead of making a decision about the adaptation of a material or the ability to penetrate the dentine tubules, one may make a choice for a material based on other positive features
