Introduction/Objective. This study determined the 12 months clinical and
radiographic periapical healing of teeth with apical periodontitis treating
with different formulations of calcium hydroxide (CH): paste (CHpaste) and
gutta-percha points (CH-GP), and chlorhexidine (CHX): gel (CHX-gel) and
gutta-percha points (CHX-GP). Methods. Eighty patients with chronic apical
periodontitis were randomly allocated to 4 different treatment groups
according to the intracanal medicament used: CH-paste, CH-GP, CHX-gel and
CHX-GP group. Seventy eight patients were analyzed clinically and
radiographically 12-month postoperatively. The Periapical index (PAI) was
used for radiographic evaluation of treatment success. Results. Overall
outcome was classified according to radiographic evaluation only, because in
all patients clinical success was observed. In all groups significant
reduction in PAI scores were observed (p < 0.001). The proportions of healed
teeth (PAI ≤ 2) were 73.7%, 60.0%, 68.4% and 65.0% in CH-paste, CH-GP, CHXgel
and CHX-GP group, respectively, with no significant differences between the
groups. Conclusion. The results suggested that there are no differences
between investigated CH- and CHXdelivery systems regarding treatment outcome
of teeth with apical periodontitis.
