简要总结
Symptomatic irreversible pulpitis is an abnormal condition characterized by severe pain which lingers even after the removal of stimulus and is spontaneous. According to the older concept, pulp once inflamed gets affected in toto and treatment requires complete removal of diseased pulp tissue from root canal space. However, new concept refutes the older one and states that pulpal inflammation occurs by tissue compartment and even in the cases of irreversibly inflamed pulp, there are areas of uninflamed and disease free pulp tisuue. This has led to a paradigm shift in the treatment protocol from root canal treatment to pulp preservation by pulpotomy. MTA is currently the most preferred material for pulpotomy. But MTA have a long setting time. Hence, it is advised to place a final definitive restoration over MTA after 24 hours. This two-step MTA pulpotomy technique have certain disadvantages such as more time consuming, increased chances of possible iatrogenic errors,Inceased cost and increased chances of microleakage. However, current evidences from recent in-vitro studies suggests that glass ionomer cement can be placed over MTA in same visit without any adverse reaction between the two materials. Till this date there are no clinical studies in the literature that has compared one and two step technique for MTA pulpotomy. Hence, it is proposed to conduct a comparative study for the evaluating the outcome of MTA pulpotomy after one and two step technique.
