Human pulp response after direct pulp capping with an adhesive system

الملخص EN

Background : The adhesive systems are experimentally used in direct pulp capping procedure.

The aim of this study was to evaluate the histological responses of pulp tissues after direct pulp capping with an adhesive agent.

Materials and Methods : The pulps of twenty human teeth scheduled for extraction were mechanically exposed and capped with an adhesive system and calcium hydroxide cement for 60 days.

The teeth were extracted and prepared for examination under light microscope for inflammatory responses and dentin bridge formation.

Results : The slides showed that there were variable responses which ranged from moderate to severe and progressive extension of tissue necrosis with time for teeth capped with the adhesive system.

After the application of calcium hydroxide paste, only mild tissue response was elected with complete hard tissue bridging.

Conclusion : Based on the experimental conditions, the application of the adhesive system in direct contact with mechanically exposed pulp cannot lead to acceptable repair of dentin-pulp complex.
