The purpose of this study was to determine the capability of sodium hypochlorite to digest organic debris when used as a irrigating agent during the in vivo preparation of the root canal system in root canal therapy, with emphasis on accessory canals. Sodium hypochlorite's potential to digest detached tissue was first determined on isolated pulpal tissue within the root canal system in vitro. Upon accomplishing this, teeth with clinically vital and necrotic pulps were prepared in vivo for root canal therapy using sodium hypochlorite as the irrigating solution. The teeth were then extracted, studied histologically, and the resultant effects described. An attempt was then made at correlating histologic findings with clinical variables. Sodium hypochlori te displayed active ability to digest detached and/or necrotic tissue -in vitro. Sodium hypochlorite appeared to demonstrate a similar ability to digest detached and/or necrotic tissue in the root canal system during clinical use in vitro, while it did not appear to effect vital tissue under controlled clinical conditions. A fairly consistant trend was demonstrated by sodium hypochlorite to digest organic debris from accessory canals under clinical (in vivo) conditions which appeared to be influenced by access of the solution to the organic debris and the duration of contact, although further study is required to substantiate these observations.
