| Abstract: | AIM: To observe the effect of mineral trioxide aggregate (MTA) combined with fibronectin as pulp capping agents. METHODS: The 48 pulps of 4 cats were exposed mechanically and then capped directly with MTA, MTA combined with fibronectin, calcium hydroxide, fibronectin and starch as control. After 12 weeks observation, the experimental teeth were extracted and observed with scanning electronic microscope. RESULTS: In calcium hydroxide group and MTA group, specimens showed irregular dentin bridge structures along the pulp-MTA interface. In MTA combined with fibronectin group, continuous and complete dentin bridge structures were found along the pulp-MTA interface, the crystalline-like structures were in direct contact with the dentin wall of pulp chamber, the exposed pulp sites were closed by the dentin bridge. In fibronectin and starch group, no reparative dentin was observed. CONCLUSION: The present experiment indicated that MTA combined with fibronectin was an effective pulp-capping material and may have potential for clinical application. |
