This experimental study evaluated the effects of polynucleotides on bone regeneration on rats.Defects with a diameter of 2 mm were prepared in the thickness of cortical bone of 32 rat tibiae and filled with different compounds: polynucleotide gel (PDRN), deproteinated porcine cortical bone (HDB) obtained by high temperature heating in the form of granules and a paste made of HDB granules and PDRN gel. Bone regeneration of the gaps was histologically analysed after a treatment time ranging from 1 to 12 weeks.Both PDRN and HDB stimulated bone growth and repair, but the paste prepared combining HDB granules and PDRN showed the best performance with faster filling, better osteconductive and biocompatible properties and easier handling. This study suggests that the paste prepared combining HDB and PDRN gel induces rapid bone regeneration in different clinical situations.
