Introduction. The study included application of liners and dental composites
in to cavities of six experimental animals - rabbits (Oryctolagus cuniculus).
Objective. The aim of the study was to investigate rabbit dental pulp
response to different liners. Methods. Cavity preparation for class V were
made on the maxillary central incisors and one lower incisor, while the
second lower incisor served as a control tooth. These teeth were restored
with the use of one of the following liners - Calcimol LC, ANA Liner and Fuji
II LC Improved, and Ceram-X mono dental composite. After an observation
period of five days animals were sacrificed and prepared for histological
analysis. The existence and degree of the pulp inflammation was determined by
using a light microscope. Results. Results showed that the used liners do not
cause distortion of the structure and continuity of the odontoblastic layer.
Inflammation was not registered in the control group, while in each group of
tested materials one tooth with mild signs of hyperemia was registered.
Results showed that all three tested liners demonstrated favorable effects on
the pulp of the tooth and did not lead to inflammatory reactions. Conclusion.
Histological analysis of the dental pulp of experimental animals suggests
that the liners used in this study do not compromise the integrity of the
odontoblastic layer, if it is applied over a thin layer of dentin. In each
group of tested materials one tooth with mild signs of hyperemia and
vasodilation was registered.
