Periodontitis is challenging to cure
radically due to its complex
periodontal structure and particular microenvironment of dysbiosis
and inflammation. However, with the assistance of various materials,
cell osteogenic differentiation could be improved, and the ability
of hard tissue regeneration could be enhanced. This study aimed to
explore the appropriate concentration ratio of biofriendly transglutaminase-modified
gelatin hydrogels for promoting periodontal alveolar bone regeneration.
Through a series of characterization and cell experiments, we found
that all the hydrogels possessed multi-space network structures and
demonstrated their biocompatibility. In vivo and in vitro osteogenic
differentiation experiments also confirmed that the group 40-5 (transglutaminase–gelatin
concentration ratio) possessed a favorable osteogenic potential. In
summary, we conclude that such hydrogel with a 40-5 concentration
is most conducive to promoting periodontal bone reconstruction, which
might be a new route to deal with the dilemma of clinical periodontal
treatment.
