Access cavity temporarily closed with reinforced zinc oxide eugenol.
At the end of the procedure, paper points were used to dry the canals and a temporary restoration placed to seal the
access cavity. No intracanal medication was used to confuse the effects of the irrigation solutions.
The integration of optical impressions allows the occlusal surface to be visualized precisely, thus optimizing planning for the
access cavity and the exact determination of the working lengths.
Pulp chamber was reentered through the previously prepared
access cavity. The root canal was exposed and irrigated with saline.
Endodontic
access cavity was prepared after the injection of local anesthesia and rubber dam isolation.

access cavity was restored with temporary restorative material
Subjects' self reported pain response was recorded on Heft Parker Visual Analogue Scale after local anesthetic administration during
access cavity preparation and pulp extirpation.
The shape of the
access cavity at cementoenamel junction (CEJ) was examined in cross-sectional view and classified based on Jou et al.'s [15] description of root canal.
Paul, MN USA) was densely packed into the
access cavity.
Tooth was isolated using rubber dam and
access cavity was prepared using high speed handpice with round bur and patient was asked about pain, if sensitive it was recorded in proforma.
(1) Such errors during any stage of root canal treatment (
access cavity preparation, instrumentation, and obturation) will complicate the treatment and ultimately may lead to failure of treatment.
