I think I have enough information now. The first result talks about odontoblasts forming a natural barrier in the dental pulp. I’ll include the PMID: 30128058 for reference. There's no need for further synthesis here, just a straightforward answer will work. So, I’ll present the answer as B and ensure the citation is crafted well. Let’s put it all together!
