67.78% of subjects (61/90) secured successful pulpal anaesthesia and had no pain or mild pain during
access cavity preparation and pulp extirpation while 32.22% of subjects (29/90) felt moderate to severe pain during the procedure and were recorded as unsuccessful in their respective technique (Table 2).

access cavity preparation," in Pathways of Pulp, K.
Chi square test was used to compare success of inferior alveolar nerve block in group A and B after 45 minutes and
access cavity preparation.
Similarly, the distribution of types of
access cavity errors and types of instrumentation errors were significantly different by gender (Table 1).
The final step after the last walking bleach technique is the restoration of the
access cavity with resin composite.
The
access cavity was prepared using an Endo Access kit (Dentsply).
A small moist cotton pellet was placed over the MTA, and the
access cavity was sealed with temporary filling material.
The
access cavity was modified using a round bur (Dentsply- Maillefer, Ballaigues, Switzerland).
In contrast, if the
access cavity restoration is leaking or absent, oxygen as well as moisture will enter.
After anesthesia with 4% septocaine with 1 : 100,000 adrenaline (Ubistesin Forte, 3M ESPE, Seefeld, Germany) and rubber dam isolation (Hygenic Dental Dam, Coltene Whaledent, Langenau, Germany), an
access cavity through the crown was prepared.
