Deep caries removal can break through into the pulp, the soft tissue that keeps a tooth alive. The same thing happens when a front tooth snaps in an accident and the fracture line runs through it. From there the tooth can be root filled, or the exposed pulp can be dressed with a small amount of material, sealed under a restoration and left to heal. That second option is direct pulp capping, and while it holds the tooth stays alive. Which material to place, and after which kind of exposure, is not settled. Calcium hydroxide has been used for decades. Calcium silicate cements such as MTA and Biodentine came later, and the trials comparing them are small, split between two very different clinical situations, and count success in different ways. A dentist standing over an exposed pulp has to read across all of it to decide what to place. This project works through that evidence one clinical decision at a time: which material, after which kind of exposure, and how long the result is known to hold. Expect a fortnight of reading before anybody writes a word.
Read up on how a dentist treats a pulp that has been exposed and what gets placed on it. Take one clinical decision, read the papers already gathered for it, build the table that goes with it, and write that section.
