Since ancient times, propolis has been used in medicine, while in oral medicine and dentistry it has been indicated as a direct capping material. The aim of this study was to quantify the odontoblast activity in drilling holes on dog's teeth (canine and incisor) during direct capping. Perforations were carried out in a total sample of 12 dental pieces. In half of the sample teeth were capped with propolis, and in the other half with calcium hydroxide. In all cases teeth were obturated with glass ionomer cement. Extraction of the teeth was realized after two weeks, and teeth were fixed in buffered formalin. Histological cuts of the pieces were made and stained with hematoxylin-eosin in order to carry out quantification of nuclei presence in healthy areas (away from the perforation, as well as in areas adjacent to injuries. Results showed similar odontoblast activity while using either of the materials, (p=0.9325), only differing in the arrangement of newly formed cells which in the cases where propolis was used, were palisading, similar to healthy areas. On the other hand, the same order was not observed when calcium hydroxide was used.
