Background: The present study aims to analyse the in vivo behaviour of nanohydroxyapatite and to assess its regenerative capacity in dogs affected by periodontal disease. Methods and findings: The dogs employed in the study were randomly subdivided into a control group and an experimental group. After clinical, instrumental and radiological examinations, all the subjects underwent dental prophylaxis and a bioptic sample was taken. A histopathological examination of the periodontal tissues, in correspondence to teeth with periodontopathy ranging between stages 2 and 3, followed. Regenerative therapy with applications of nanohydroxyapatite was administered only to the dogs of the experimental group. After a period of between 35 and 40 days, a further clinical, instrumental and radiological examination was carried out and a bioptic sample taken solely on the dogs whose histological examinations showed changes ascribable to periodontal disease. The results of the histopathological examination demonstrated that only the dogs in the experimental group, who underwent dental prophylaxis together with the administration of nanohydroxyapatite, showed clear signs of improvement with respect to their initial condition. Conclusions: In conclusion the study demonstrated that the nanohydroxyapatite represents a valid osteoconductive and osteoinductive graft product and confirmed its regenerative potential in periodontal therapy in dogs.

Abstract

Background: The present study aims to analyse the in vivo behaviour of nanohydroxyapatite and to assess its regenerative capacity in dogs affected by periodontal disease. Methods and findings: The dogs employed in the study were randomly subdivided into a control group and an experimental group. After clinical, instrumental and radiological examinations, all the subjects underwent dental prophylaxis and a bioptic sample was taken. A histopathological examination of the periodontal tissues, in correspondence to teeth with periodontopathy ranging between stages 2 and 3, followed. Regenerative therapy with applications of nanohydroxyapatite was administered only to the dogs of the experimental group. After a period of between 35 and 40 days, a further clinical, instrumental and radiological examination was carried out and a bioptic sample taken solely on the dogs whose histological examinations showed changes ascribable to periodontal disease. The results of the histopathological examination demonstrated that only the dogs in the experimental group, who underwent dental prophylaxis together with the administration of nanohydroxyapatite, showed clear signs of improvement with respect to their initial condition. Conclusions: In conclusion the study demonstrated that the nanohydroxyapatite represents a valid osteoconductive and osteoinductive graft product and confirmed its regenerative potential in periodontal therapy in dogs.
