The Reaction of Dental Tissues to the Protective Adhesive Materials Used in the Treatment of Deep Caries

摘要

Dentin-pulp complex protection during deep caries treatment is a basic principle in dental practice and involves the use of specific materials as liners or bases. This study aims to determine dental tissue reaction consecutively applying a classic adhesive in deep cavities in comparison with calcium hydroxide which is the biological material of choice for the protection of the dental pulp. Histopathological images show the presence of significant vascular and cellular changes occur in the pulp tissue in case of dentin adhesive used as protective material compared to defensive reaction of calcium hydroxide generated by deposition of tertiary dentin.
