Abstract

Access cavity preparation is defined as endodontic coronal preparation which enables unobstructed access to the canal orifices, a straight line access to apical foramen, complete control over instrumentation and to accommodate obturation technique. The main objective of the access cavity preparation is to create a smooth, straight line access to the canal system and the apex. The optimal access cavity results in the straight entry into the canal orifices with line angles forming a funnel which drops smoothly into the canals. Any improperly prepared access cavity can impair the instrumentation, disinfection and therefore obturation resulting in poor prognosis of the treatment. Sometimes depending upon the location and number of canals, modification of the outline form may be needed.
