X-ray examination was performed before surgery to explore
periapical tissue and root conditions.
Incorrect use of devitalizing agents is related to secondary pain, the drug filtering into the marginal periodontium, and irritation and inflammation of the
periapical tissue.
It was due to infected root canal system and remnant of the necrotic pulp induced the colonisation and formation of bacterial biofilm within the complexity of root canal system which in turn the bacterial invasion reached the
periapical tissue to cause apical periodontitis.
Periapical tissue reactions to calcium hydroxide and MTA after external root resorption as a sequela of delayed tooth replantation.
In such scenario use of Intra-canal medicaments can help in eliminating these bacteria remaining after chemicomechanical instrumentation and can provide the environment conducive to
periapical tissue repair (15-16).
In addition to the biological and immunological factors, the followings can be effective in causing pain: Chemical mediators, changes in local adaptation of
periapical tissue, changes in cyclic nucleotides, immunological phenomena and psychosomatic factors [2].
Periapical tissue responses and cementum regeneration with amalgam, superEBA, and MTA as root-end filling materials.
Microbiological examination of roots canal and
periapical tissue of human teeth.
Chow, The
periapical tissue reaction to a calcium phosphate cement in the teeth of monkeys, J.
Vitapex has some disadvantages like irritation to
periapical tissue if extruded beyond apex and has less antimicrobial properties.
There is no evidence of adverse histological reaction at the
periapical tissue.
Periapical tissue reactions to rootfilled teeth whose canals had been instrumented short of their apices.
