| Research Abstract |
In Japan, challenging cases of dental disease such as root surface caries become a problem in step with a rapid aging society. We tried to develop a new comprehensive treatment of caries based on minimum intervention. First, we developed the remineralization and reinforcement of decalcified tooth using ammonium hexafluorosilicate (SiF) with antimicrobial agents. Second, we developed the disinfection of caries related bacteria with electro-magnetic wave irradiation (EMWI). And finally, we examined the anti-inflammatory effects of tea catechin to fibroblasts to develop a new treatment for deep carious lesion.
We found the increase of crystallinity of hydroxyapatite with SiF treatment and antibacterial agents such as catechin are effective with SiF. Also, we found the bacteriocidal or inactive effects of EMWI on S. mutans. Catechin had inhibited the production of cytokines and chemokines from pulpal fibroblasts.
These results indicate the possibility of new caries treatment.
