Abstract :
Introduction: The aim of the present investigation was to compare the efficacy of mineral
trioxide aggregate (MTA) and 0.2% chlorhexidine (CHX) mixture to pure MTA, as a pulp
capping material. Methods and Materials: The pulp of 24 lateral incisors and canines from
four dogs were exposed and capped either with MTA or MTA+0.2% CHX. After 2 months
the animals were sacrificed and the teeth were prepared for histological evaluation in terms
of calcified bridge formation, the degree of inflammation and presence of necrosis. The
Fisher’s exact test was used for data analysis. Results: The results showed that formation
of complete calcified bridge in MTA specimens was significantly more than MTA+CHX
(P<0.05). No significant difference was found in the degree of inflammation and necrosis
between MTA and MTA+CHX groups (P>0.05). Conclusion: Mixing MTA with CHX as
pulp capping agent had a significant negative impact on formation of calcified bridge on
directly capped dog’s teeth.
