The effect of changing apical foramen diameter on regenerative potential of mature teeth with necrotic pulp and apical periodontitis

ConclusionIncreasing the apical size diameter was associated with less inflammatory cell count, less percentage of bone resorption, more tissue ingrowth, and more percentage of new hard tissue formation inside root canal. The minimum apical diameter that should be enlarged for RET is 0.4  mm.Clinical relevanceRET could be used as an alternative procedure to RCT for the treatment of mature teeth with necrotic pulp and apical periodontitis.
