Use of microporous hydroxyapatite material in regenerative treatment of periodontal tissues in dogs: a clinical study
One of the biomaterials used in veterinary dentistry is hydroxyapatite (HAp). It aids the biological process of bone reconstruction and provides the basis on which damaged tissues can be rebuilt. It is also exceptionally osteoconductive and bioactive towards bone and other tissues. The aim of the present study was to verify the usefulness of hydroxyapatite microporus ceramics for the treatment of periodontal diseases and post-extraction defects. The study was performed on 40 dogs. Dogs were qualified for the in vivo test: 2 study groups and 2 control groups (K1, K2) were created. Group G1 comprised 10 dogs diagnosed with periodontitis with 4-8 mm gingival pockets and mobility of mandibular/maxillary incisors. In order to avoid extraction, hydroxyapatite implantation into the bone pockets was performed. Group G2 comprised 10 dogs that required the extraction of maxillary canines, following which biomaterial was introduced into the post-extraction cavities. Control groups were performed without using of microporous hydroxyapatite. In group G1, animals displayed significant shallowing of gingival pockets. The mean depth of pockets was significantly reduced in those dogs and considerably better reconstruction of periodontal tissues was observed when compared to the control group K1. In group G2, significantly faster healing of bone cavities was stated when compared to the respective control group K2. The study confirmed the validity of using microporous hydroxyapatite granules and shaped blocks in reconstructive periodontal treatment as well as prevention of oronasal fistulas after canines extraction and facilitation of the post-extraction healing process..
