title: Acute apical periodontitis: incidence of post-operative pain using two different root canal dressings.
abstract: A clinical study using non-vital maxillary central incisors exhibiting acute apical periodontitis was carried out to evaluate the incidence of post-operative pain after biomechanical preparation and dressing with a calcium-hydroxide paste or a corticosteroid-antibiotic solution. Sixty teeth from 48 patients were prepared and dressed on the first visit and re-evaluated clinically 7 days later. No difference was observed in the incidence of post-operative pain between the two groups.
